Android 11 SystemUI(状态/导航栏)-状态栏下拉时图标的隐藏与通知面板的半透黑色背景
概述本文续自:Android 11 的状态栏的隐藏PS本文虽然同属于SystemUI, 但目前并 没有 打算整理成专橍或撰写一个系列的想法.仅仅为了记录一些过程, 留下那些容易被遗忘的点滴.开始下拉时状态栏图标被隐藏 状态橍的图标在用户开始触摸(ACTION_DOWN)后, 会开始展开, 显示扩展面板, 同时, 隐藏状态橍上的通知和状态图标. 在手机上表现有可能不同, 在android 13上, 在点击没有作用, 只有下拉一定的距离,才会开始隐藏.device-2022-12-21-190046隐藏从触摸下按开始, 参照下图:忽略过程代码, 直接上最后一部分:frameworks/base/packages/SystemUI//src/com/android/systemui/statusbar/phone/CollapsedStatusBarFragment.java@Override public void disable(int displayId, int state1, int state2, boolean animate) { if (displayId != getContext().getDisplayId()) { return; } state1 = adjustDisableFlags(state1); final int old1 = mDisabled1; final int diff1 = state1 ^ old1; mDisabled1 = state1; if ((diff1 & DISABLE_SYSTEM_INFO) != 0) { if ((state1 & DISABLE_SYSTEM_INFO) != 0) { hideSystemIconArea(animate); hideOperatorName(animate); } else { showSystemIconArea(animate); showOperatorName(animate); } } if ((diff1 & DISABLE_NOTIFICATION_ICONS) != 0) { if ((state1 & DISABLE_NOTIFICATION_ICONS) != 0) { hideNotificationIconArea(animate); } else { showNotificationIconArea(animate); } } // The clock may have already been hidden, but we might want to shift its // visibility to GONE from INVISIBLE or vice versa if ((diff1 & DISABLE_CLOCK) != 0 || mClockView.getVisibility() != clockHiddenMode()) { if ((state1 & DISABLE_CLOCK) != 0) { hideClock(animate); } else { showClock(animate); } } } protected int adjustDisableFlags(int state) { boolean headsUpVisible = mStatusBarComponent.headsUpShouldBeVisible(); if (headsUpVisible) { state |= DISABLE_CLOCK; } if (!mKeyguardStateController.isLaunchTransitionFadingAway() && !mKeyguardStateController.isKeyguardFadingAway() && shouldHideNotificationIcons() && !(mStatusBarStateController.getState() == StatusBarState.KEYGUARD && headsUpVisible)) { state |= DISABLE_NOTIFICATION_ICONS; state |= DISABLE_SYSTEM_INFO; state |= DISABLE_CLOCK; } if (mNetworkController != null && EncryptionHelper.IS_DATA_ENCRYPTED) { if (mNetworkController.hasEmergencyCryptKeeperText()) { state |= DISABLE_NOTIFICATION_ICONS; } if (!mNetworkController.isRadioOn()) { state |= DISABLE_SYSTEM_INFO; } } // The shelf will be hidden when dozing with a custom clock, we must show notification // icons in this occasion. if (mStatusBarStateController.isDozing() && mStatusBarComponent.getPanelController().hasCustomClock()) { state |= DISABLE_CLOCK | DISABLE_SYSTEM_INFO; } return state; }关于CollapsedStatusBarFragment 在读到CollapsedStatusBarFragment相关代码的时候, 一时没办法把Fragment与SystemUI串联起来, 这源于传统Fragment的使用习惯: 在Activity中, 获取一个FragmentManager, 创建各种Fragment, 调用replace, show, hide… 难道SystemUI也吃这一套? 状态栏和导航栏不一直是通过WindowManager.addView()直接往里面丢的么! CollapsedStatusBarFragment 本身没什么特别的, 它只是一个android.app.Fragment, 没有特殊的地方, 特殊的是FragmentController, 它与传统的Fragment使用方法完全不同, 参考 frameworks/base/packages/SystemUI/src/com/android/systemui/fragments/FragmentHostManager.java编写一段测试代码, 以便更直观了解它的用法:public class TestActivity extends Activity{ void testFragmentController(Context ctx, Handler h, int winAnim){ if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) { FragmentController fragCtrl = FragmentController.createController(new FragmentHostCallback<Object>(ctx, h, 0) { @Override public Object onGetHost() { return null; } @Override public <T extends View> T onFindViewById(int id) { return findViewById(id); } }); //java.lang.IllegalStateException: Activity has been destroyed // at android.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1913) fragCtrl.attachHost(null); fragCtrl.dispatchCreate(); fragCtrl.dispatchStart(); fragCtrl.dispatchResume(); //java.lang.IllegalArgumentException: No view found for id 0x7f08007c (com.android.factorytest:id/flRoot) for fragment SimpleFragment{2b5da47 #0 id=0x7f08007c} fragCtrl.getFragmentManager() .beginTransaction() .replace(R.id.flRoot, new SimpleFragment()) .commit(); } } public static class SimpleFragment extends Fragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { TextView tv = new TextView(getActivity()); tv.setLayoutParams(new ViewGroup.LayoutParams(UiTools.MATCH_PARENT, UiTools.MATCH_PARENT)); tv.setText("FragmentController"); tv.setTextSize(36); return tv; } } }重点关注代码中的createController和FragmentHostCallback, 当创建完成后, 便可以通过 FragmentController的getFragmentManager获取FragmentManager, 接下来就是熟悉的操作, 不多描述.下拉通知黑色背景 在下拉通知面板的过程中, 存在两部分的半透明背景, 第一部分(上)比较明显, 第二部分比较隐藏晦.效果如下图:这是一个自定义的View, 从layout文件中可以找到它: ScrimViewframeworks/base/packages/SystemUI/res/layout/super_notification_shade.xml<com.android.systemui.statusbar.phone.NotificationShadeWindowView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:sysui="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <!-- 省略代码 --> <com.android.systemui.statusbar.ScrimView android:id="@+id/scrim_behind" android:layout_width="match_parent" android:layout_height="match_parent" android:importantForAccessibility="no" sysui:ignoreRightInset="true" />frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/ScrimView.javadiff --git a/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/ScrimView.java b/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/ScrimView.java index 7f30009cda..907d58c267 100644 --- a/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/ScrimView.java +++ b/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/ScrimView.java @@ -69,7 +69,7 @@ public class ScrimView extends View { @Override protected void onDraw(Canvas canvas) { - if (mDrawable.getAlpha() > 0) { + if (false && mDrawable.getAlpha() > 0) {//强制不进行绘制, 就不会出现半透明背景 mDrawable.draw(canvas);

linphone android sdk 源码下载编译
前言 前面的有写过Android 使用Linphone SDK开发SIP客户端相关的文章, 在后续的开发过程中, 为了更深入了解linphone, 便尝试下载SDK源码自行编译. 关于linphone这里不作过多介绍, 可以参考前面的文章. Linphone-SDK 是一个将 Liblinphone 及其依赖项捆绑为 git 子模块的项目，目的是简化整个 Liblinphone 套件的编译和打包，包括 Mediastreamer2、Belle-sip、oRTP 等。 它的编译生成一个 SDK，适合创建在这些组件之上运行的应用程序。非 Linphone 团队开发或维护的子模块分组在 external/ 目录中。 当前支持的平台有 Android、iOS、Desktop（Linux、Windows、Mac OS X）和 UWP（Universal Windows Platform）。clone 代码GitLab linphone-sdkgit clone https://gitlab.linphone.org/BC/public/linphone-sdk.git注意: 为什么不使用GitHub上的仓库# ******** # **注意** # ******** #从GitHub上克隆下来的代码, 不能正常编译, 原因是有些模块找不到, 更新/下载不来. https://github.com/BelledonneCommunications/linphone-sdk git clone https://github.com/BelledonneCommunications/linphone-sdk.git源码下载[2GB]提取码: 4x4c环境及信赖系统: Ubuntu 20.04内存: 16GB存储: 512GB工具包:Cmake >= 3.11python >= 3.6pip (or pip3 if the build machine has both python2 and python3)yasmnasmdoxygenPystache (use pip install pystache or pip3 install pystache)six (use pip install six or pip3 install six)编译克隆下来解压出来后, 依赖的库代码基本为空, 通过下面的命令, 可以检索出所需要库代码.检索依赖项Linphone-SDK 的 git 存储库包含 git 子模块。 它必须使用 --recursive 选项进行克隆。 更新或切换分支后，永远不要忘记检查和更新子模块：git submodule update --init --recursive这个过程需要较长的时间, 具体看网络条件, 若出现失败建议检查下网络原因, 另外考虑下是否外网访问的问题.完成后, 目录文件 列表:linphone-sdk$ ll total 248 drwxrwxr-x 35 android android 4096 12月 16 15:57 ./ drwxrwxr-x 21 android android 4096 12月 16 09:22 ../ drwxrwxr-x 6 android android 4096 12月 15 20:09 bcg729/ drwxrwxr-x 10 android android 4096 12月 15 20:09 bcmatroska2/ drwxrwxr-x 8 android android 4096 12月 15 20:09 bctoolbox/ drwxrwxr-x 11 android android 4096 12月 15 20:09 bcunit/ drwxrwxr-x 9 android android 4096 12月 15 20:09 belcard/ drwxrwxr-x 9 android android 4096 12月 15 20:09 belle-sip/ drwxrwxr-x 9 android android 4096 12月 15 20:09 belr/ drwxrwxr-x 7 android android 4096 12月 15 20:09 bzrtp/ -rw-rw-r-- 1 android android 2069 12月 15 19:45 CHANGELOG.md drwxrwxr-x 8 android android 4096 12月 16 11:00 cmake/ drwxrwxr-x 10 android android 4096 12月 15 20:09 cmake-builder/ -rw-rw-r-- 1 android android 5602 12月 15 19:45 CMakeLists.txt drwxrwxr-x 2 android android 4096 12月 15 19:45 docker-files/ -rw-rw-r-- 1 android android 10 12月 15 19:45 .envrc drwxrwxr-x 26 android android 4096 12月 15 19:45 external/ -rw-rw-r-- 1 android android 7121 12月 15 19:45 flake.lock -rw-rw-r-- 1 android android 4274 12月 15 19:45 flake.nix drwxrwxr-x 9 android android 4096 12月 15 19:46 .git/ drwxrwxr-x 3 android android 4096 12月 15 19:45 .github/ -rw-rw-r-- 1 android android 302 12月 15 19:45 .gitignore drwxrwxr-x 9 android android 4096 12月 15 19:45 .gitlab-ci-files/ -rw-rw-r-- 1 android android 1598 12月 15 19:45 .gitlab-ci-tunnel.yml -rw-rw-r-- 1 android android 3439 12月 15 19:45 .gitlab-ci.yml -rw-rw-r-- 1 android android 4552 12月 15 19:45 .gitmodules drwxrwxr-x 17 android android 4096 12月 15 20:09 liblinphone/ -rw-rw-r-- 1 android android 34523 12月 15 19:45 LICENSE.txt drwxrwxr-x 9 android android 4096 12月 15 20:09 lime/ drwxrwxr-x 14 android android 4096 12月 15 20:09 mediastreamer2/ drwxrwxr-x 3 android android 4096 12月 15 20:09 msaaudio/ drwxrwxr-x 6 android android 4096 12月 15 20:09 msamr/ drwxrwxr-x 2 android android 4096 12月 15 20:09 msandroidcamera2/ drwxrwxr-x 3 android android 4096 12月 15 20:09 mscodec2/ drwxrwxr-x 4 android android 4096 12月 15 20:09 msoboe/ drwxrwxr-x 5 android android 4096 12月 15 20:09 msopenh264/ drwxrwxr-x 5 android android 4096 12月 15 20:09 mssilk/ drwxrwxr-x 3 android android 4096 12月 15 20:09 mswasapi/ drwxrwxr-x 4 android android 4096 12月 15 20:09 mswebrtc/ drwxrwxr-x 4 android android 4096 12月 15 20:10 mswinrtvid/ drwxrwxr-x 10 android android 4096 12月 15 20:10 ortp/ drwxrwxr-x 7 android android 4096 12月 15 20:10 postquantumcryptoengine/ -rw-rw-r-- 1 android android 13876 12月 15 19:45 README.md drwxrwxr-x 5 android android 4096 12月 15 19:45 tester/开始编译:# 设置Android SDK 路径 linphone-sdk$ export ANDROID_SDK_ROOT=/home/android/Android/Sdk # 设置Android NDK 路径 linphone-sdk$ export PATH=$PATH:/home/android/Android/Sdk/ndk/20.0.5594570 linphone-sdk$ mkdir build linphone-sdk$ cd build # 参考官方 linphone-sdk/build$ cmake .. -DLINPHONESDK_PLATFORM=Android -DLINPHONESDK_ANDROID_ARCHS=arm64,x86,armv7 -DENABLE_SILK=YES -DENABLE_G729==YES # 开始编译 linphone-sdk/build$ cmake --build . -j4编译时间比较长, 耐心等待即可.-DLINPHONESDK_ANDROID_ARCHS的值, 可以参考:arm -> armeabi 已不受支持:CMake Error at /home/android/Android/Sdk/ndk/20.0.5594570/build/cmake/android.toolchain.cmake:177 (message): armeabi is no longer supported.

Android 11 的状态栏的隐藏
概述Android 11 的状态栏与导航栏较之前的版本有较大的差异, 在Android 7.0 SystemUI 状态/导航栏的隐藏与显示中所描述的部分内容已不再适用.比如, 自动隐藏的时间, 隐藏的动画, 较之前的版本已面目全非, 本文将对隐藏状态栏部分的内容进行一些补充.APP如何隐藏状态栏参考文档:隐藏状态栏_Android 开发者_Android Developers.pdf)方法一:<application ... android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen" > ... </application>方法二: public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // If the Android version is lower than Jellybean, use this call to hide // the status bar. if (Build.VERSION.SDK_INT < 16) { getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); } setContentView(R.layout.activity_main); } ... }方法三:(在4.1(SDK 16)及之上)View decorView = getWindow().getDecorView(); // Hide the status bar. int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; decorView.setSystemUiVisibility(uiOptions); // Remember that you should never show the action bar if the // status bar is hidden, so hide that too if necessary. ActionBar actionBar = getActionBar(); actionBar.hide();状态栏是怎么被隐藏的1. 通过上面的方式主动调用接口设置窗口属性, 由系统判断并完成隐藏frameworks/base/core/java/android/view/InsetsController.java@Override public void onReady(WindowInsetsAnimationController controller, int types) { mController = controller; if (DEBUG) Log.d(TAG, "default animation onReady types: " + types); if (mDisable) { onAnimationFinish(); return; } mAnimator = ValueAnimator.ofFloat(0f, 1f); mAnimator.setDuration(mDurationMs); mAnimator.setInterpolator(new LinearInterpolator()); Insets hiddenInsets = controller.getHiddenStateInsets(); // IME with zero insets is a special case: it will animate-in from offscreen and end // with final insets of zero and vice-versa. hiddenInsets = controller.hasZeroInsetsIme() ? Insets.of(hiddenInsets.left, hiddenInsets.top, hiddenInsets.right, mFloatingImeBottomInset) : hiddenInsets; Insets start = mShow ? hiddenInsets : controller.getShownStateInsets(); Insets end = mShow ? controller.getShownStateInsets() : hiddenInsets; Interpolator insetsInterpolator = getInterpolator(); Interpolator alphaInterpolator = getAlphaInterpolator(); mAnimator.addUpdateListener(animation -> { float rawFraction = animation.getAnimatedFraction();

android WebRtc 视频通话(P2P)
概述 WebRTC名称源自网页实时通信(Web Real-Time Communication)的缩写，是一个支持网页浏览器进行实时语音对话或视频对话的技术，是谷歌2010年以6820万美元收购Global IP Solutions公司而获得的一项技术。Google于2011年6月3日开源的即时通讯项目，旨在使其成为客户端视频通话的标准。其实在Google将WebRTC开源之前，微软和苹果各自的通讯产品已占用很大市场份额（如Skype），Google也是为了快速扩大市场，所以将他给开源。在行业内得到了广泛的支持和应用，成为下一代视频通话的标准。更多介绍可以去官网上看。 WebRTC被誉为是web长期开源开发的一个新启元，是近年来Web开发的最重要创新。WebRTC允许Web开发者在其web应用中添加视频聊天或者点对点数据传输，不需要复杂的代码或者昂贵的配置。目前支持Chrome、Firefox和Opera，后续会支持更多的浏览器，它有能力达到数十亿的设备。 目前，WebRTC的应用已经不局限在浏览器与浏览器之间，通过官方提供的SDK，我们可以很容易的实现本地应用间的音视频传输。在Android平台上，我们也非常容易的集成WebRTC框架，用非常简洁的代码就能实现强大、可靠的音视频传输功能。实现说明本文代码修改自meshenger-androidTrue P2P Voice- and video phone calls without the need for accounts or access to the Internet. There is no discovery mechanism, no meshing and no servers. Just scan each others QR-Code that will contain the contacts IP address. This works in many local networks such as community mesh networks, company networks or at home.翻译如下:真正的 P2P 语音和视频电话呼叫，无需帐户或访问互联网。 没有发现机制，没有网格化，也没有服务器。 只需相互扫描包含联系人 IP 地址的二维码即可。 这适用于许多本地网络，例如社区网状网络、公司网络或家庭网络。版本: meshenger-android-3.0.3 最后的JAVA版本, 最新版本已经改用kotlin基本情况: 功能满足一个局域网P2P的视频通话功能二维码身份生成-----正常二维码扫码添加通讯录-----正常连接发起通话------异常主要问题在于无法创建两端之间的Socket连接, 与WebRTC本身无关通讯加解密 ----- 异常视频通话 ---- 只显示对方视频不显示自身感谢作者1.增加WebRtc支持build.gradledependencies { implementation 'org.webrtc:google-webrtc:1.0.32006' }2.关键代码及应用创建 PeerConnectionFactoryprivate void initRTC() { log("initRTC");

Android 使用Linphone SDK开发SIP客户端
平台RK3288 + Linphone 5.1.0 + Android Studio概述 简单来说, 有了解过互联网电话服务或IM(即时消息)功能的.一般都会接触到VOIP和SIP, 实现即时通讯, 发文本消息也好话音通话也好, 甚至于视频通话.关于SIP（Session Initiation Protocol，会话初始协议） VoIP是一个广义术语，可用于描述任何互联网电话服务，从低成本的住宅服务到企业统一通信工具的复杂实现。VoIP是一个可以用来描述任何基于Internet的电话服务的术语，而SIP是一种用于大多数类型VoIP部署的通信协议。 在早期开发android的SIP 客户端的时候, 常常可以看到sipdroid的身影, 在前面的文章中已经有提及过并使用测试过, 只是这个项目目前来看, 只能用于做做DEMO, 简单的测试一些功能, 如注册, 登陆, 发文本消息之类的, 项目的推进/更新也不积极,|-- 尝试过另外两个项目: |–csipsimple: 不好用/不会用 |–abto_sip: 可测试用, 某些平台崩溃,官方付费最终采用了Linphone 自 2001 年作为第一个在 Linux 上使用 SIP 的开源应用程序推出以来，Linphone 已经变得非常流行，尤其是在开源社区中。 我们的工程团队一直致力于 Linphone 项目，以支持最流行平台的最新版本，并提供高级语音/视频和即时消息功能。linphone-android客户端源码linphone-SDK使用Linphone-sdk打造一个SIP客户端Gradle 版本从linphone-SDK下载对应SDK并添加依赖当前使用的版本是 linphone-sdk-android-5.1.0-beta.aarbuild.gradledependencies { implementation files('libs/linphone-sdk-android-5.1.0-beta.aar') }SipPhone.java : 初始化import org.linphone.core.Account; import org.linphone.core.AuthInfo; import org.linphone.core.Call; import org.linphone.core.CallParams; import org.linphone.core.Config; import org.linphone.core.Core; import org.linphone.core.CoreListener; import org.linphone.core.CoreListenerStub; import org.linphone.core.Factory; public class SipPhone extends IPhone { Factory factory; Core core; AuthInfo user; AccountParams accountParams; Call currentCall; //初始化Factory, 在APP启动时调用. public static void loadSipLibs(){ Factory.instance(); } void initSip(Activity activity){ Logger.i(TAG, "initSip"); factory = Factory.instance(); core = factory.createCore(null, null, activity); core.addListener(coreListener); //配置视频通话 core.enableVideoCapture(true); core.enableVideoDisplay(true); core.getVideoActivationPolicy().setAutomaticallyAccept(true); //音频部分, 这里增加了一个遍历, 用于设置指定的音频格式. //h264, no VP8 fixed outgoing call no video.

Android 离线文字转语音功能-TTS(Text To Speech)
前言 在 Android 中，TTS全称叫做 Text to Speech，从字面就能理解它解决的问题是什么，把文本转为语音服务，意思就是你输入一段文本信息，然后Android 系统可以把这段文字播报出来。这种应用场景目前比较多是在各种语音助手APP上，很多手机系统集成商内部都有内置文本转语音服务，可以读当前页面上的文本信息。同样，在一些阅读类APP上我们也能看到相关服务，打开微信读书，里面就直接可以把当前页面直接用语音方式播放出来，特别适合哪种不方便拿着手机屏幕阅读的场景。 Android系统从1.6版本开始就支持TTS, 不过遗憾的是系统默认的TTS引擎:Pico TTS，并不支持中文。 在查找了许相关资料后, 发现很多的资源都已经失效, APK找不到, 对应的页面404. 更多的厂商则转成了开放平台甚至不再提供离线/免费服务.目前找到的离线TTS注:下面的链接可能需要科学上网才可以访问使用首先, 安装对应的TTS应用, 再在设置中设置对应的语音输出服务一般设置的步骤为: 设置>无障碍>文字转语音(TTS)输出程序调用只需使用SDK标准的TTS接口即可.在介绍TTS使用的文章中, 下面这一段的代码, 对于前面的科大讯飞或ITRI TTS并没什么效果, 只是多了一个弹窗, 当然, 也可以理解为, 这两个APP并没有按标准接口开发.//显示应用选择窗.

可以从packages/services/Telephony着手, 将PhoneApp中的代码移到Service中去执行, 这样改了之后, 会产生什么影响, 需要做更多验证, 至少目前测试来说, 4G部分功能及开机广播功能都正常.

Android 11 上的文件读写权限(MANAGE_EXTERNAL_STORAGE)
平台 Android11 + RK3566 + AndroidStudioAndroid 权限的变化, 几乎每个版本的SDK都会有, 其中最大的一次是在6.0时, 增加的动态权限申请读写存储的权限也几经更迭, 对开发人员来说, 越来越难.比如, 本文所要讨论的:允许管理所有文件如何出现上面两种不同的文件权限选项?1.首先是 targetSdkVersion 大于等于 30. (build.gradle)2.当声明了 READ_EXTERNAL_STORAGE和WRITE_EXTERNAL_STORAGE仅允许访问媒体文件3.当声明了 MANAGE_EXTERNAL_STORAGE 会增加允许管理所有文件4.targetSdkVersion <= 28 时, 只有允许管理所有文件和 拒绝 选项.编写测试代码执行以下动作:1.申请权限2.获取内部存储下的1.txt文件3.若文件存在, 删除并输出结果4.尝试写入文件5.读写失败:2022-09-03 07:25:11.067 1262-10770/com.android.providers.media.module E/MediaProvider: insertFileIfNecessary failed

Android 11 替换Launcher后导致近期任务无效
平台 RK3566 + Android 11概述 替换默认主界面, 更换为指定第三方Launcher后, 点击导航栏的RECENT键无效. 究其原因在于, 在旧版本SDK上, 删除Launcher3并不会影响RECENT的功能 , 而在新的SDK上, RECENT功能集成于Launcher3目录下, 删除 Launcher3后, 导致SystemUI调用对应的RECENT界面启动的服务失败.过程疏理frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarFragment.java@Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); mNavigationBarView = (NavigationBarView) view; final Display display = view.getDisplay(); // It may not have display when running unit test. if (display != null) { mDisplayId = display.getDisplayId(); mIsOnDefaultDisplay = mDisplayId == Display.DEFAULT_DISPLAY; } mNavigationBarView.setComponents(mStatusBarLazy.get().getPanelController()); mNavigationBarView.setDisabledFlags(mDisabledFlags1); mNavigationBarView.setOnVerticalChangedListener(this::onVerticalChanged); mNavigationBarView.setOnTouchListener(this::onNavigationTouch); if (savedInstanceState != null) { mNavigationBarView.getLightTransitionsController().restoreState(savedInstanceState); } mNavigationBarView.setNavigationIconHints(mNavigationIconHints); mNavigationBarView.setWindowVisible(isNavBarWindowVisible()); prepareNavigationBarView(); } private void prepareNavigationBarView() { mNavigationBarView.reorient(); ButtonDispatcher recentsButton = mNavigationBarView.getRecentsButton(); recentsButton.setOnClickListener(this::onRecentsClick); recentsButton.setOnTouchListener(this::onRecentsTouch); recentsButton.setLongClickable(true); recentsButton.setOnLongClickListener(this::onLongPressBackRecents); } private void onRecentsClick(View v) { if (LatencyTracker.isEnabled(getContext())) { LatencyTracker.getInstance(getContext()).onActionStart( LatencyTracker.ACTION_TOGGLE_RECENTS); } mStatusBarLazy.get().awakenDreams(); mCommandQueue.toggleRecentApps(); }frameworks/base/packages/SystemUI/src/com/android/systemui/recents/Recents.java@Override public void toggleRecentApps() { // Ensure the device has been provisioned before allowing the user to interact with // recents if (!isUserSetup()) { return; } mImpl.toggleRecentApps(); }frameworks/base/packages/SystemUI/src/com/android/systemui/recents/OverviewProxyRecentsImpl.java@Override public void toggleRecentApps() { Log.d(TAG, "toggleRecentApps"); // If connected to launcher service, let it handle the toggle logic IOverviewProxy overviewProxy = mOverviewProxyService.getProxy(); if (overviewProxy != null) { final Runnable toggleRecents = () -> { try { if (mOverviewProxyService.getProxy() != null) { mOverviewProxyService.getProxy().onOverviewToggle(); mOverviewProxyService.notifyToggleRecentApps(); } } catch (RemoteException e) { Log.e(TAG, "Cannot send toggle recents through proxy service.", e); } }; // Preload only if device for current user is unlocked if (mStatusBarLazy != null && mStatusBarLazy.get().isKeyguardShowing()) { mStatusBarLazy.get().executeRunnableDismissingKeyguard(() -> { // Flush trustmanager before checking device locked per user mTrustManager.reportKeyguardShowingChanged(); mHandler.post(toggleRecents); }, null, true /* dismissShade */, false /* afterKeyguardGone */, true /* deferred */); } else { toggleRecents.run(); } return; } else { // Do nothing } }重点看下overviewProxyframeworks/base/packages/SystemUI/src/com/android/systemui/recents/OverviewProxyService.javaprivate static final String ACTION_QUICKSTEP = "android.intent.action.QUICKSTEP_SERVICE"; @SuppressWarnings("OptionalUsedAsFieldOrParameterType") @Inject public OverviewProxyService(Context context, CommandQueue commandQueue, NavigationBarController navBarController, NavigationModeController navModeController, NotificationShadeWindowController statusBarWinController, SysUiState sysUiState, PipUI pipUI, Optional<Divider> dividerOptional, Optional<Lazy<StatusBar>> statusBarOptionalLazy, BroadcastDispatcher broadcastDispatcher) { super(broadcastDispatcher); mContext = context; mPipUI = pipUI; mStatusBarOptionalLazy = statusBarOptionalLazy; mHandler = new Handler(); mNavBarController = navBarController; mStatusBarWinController = statusBarWinController; mConnectionBackoffAttempts = 0; mDividerOptional = dividerOptional; //frameworks/base/core/res/res/values/config.xml // <string name="config_recentsComponentName" translatable="false">com.android.launcher3/com.android.quickstep.RecentsActivity</string> mRecentsComponentName = ComponentName.unflattenFromString(context.getString( com.android.internal.R.string.config_recentsComponentName)); mQuickStepIntent = new Intent(ACTION_QUICKSTEP) } //绑定服务 private void internalConnectToCurrentUser() { //..............

Android 裁剪摄像头预览窗口-SurfaceView
概述 Android 下, 使用SurfaceView显示摄像头预览, 通常使用的是一个矩形窗口, 如果, 要使用一个圆形窗口呢?先上效果图未打开摄像头打开摄像头实现过程视图布局实现圆形裁剪的方法有很多, 最简单的, 可以在SurfaceView上方增加一个视图遮罩, 挡住不需要显示的区域即可遮罩的方法有一个问题:上图中, 属于ImageView的红色区域也会被遮挡本文中采用的方法是:用一个RelativeLayout包含SurfaceView, 通过裁剪RelativeLayout来实现:@Override protected void dispatchDraw(Canvas canvas) { //裁剪圆型画布,使SurfaceView显示圆形区域图像 canvas.save(); canvas.clipPath(path); super.dispatchDraw(canvas); canvas.restore(); }增加按键位置的拖动功能, 主要是为了解决验证一个问题://设置输入监听, 用于拖动按键位置. btn.setOnTouchListener(new View.OnTouchListener() { float cx, cy, dx, dy; int tx, ty; @Override public boolean onTouch(View v, MotionEvent event) { cx = event.getRawX(); cy = event.getRawY(); switch(event.getAction()){ case MotionEvent.ACTION_DOWN: dx = cx; dy = cy; tx = lpBtn.leftMargin; ty = lpBtn.topMargin; break; case MotionEvent.ACTION_MOVE: lpBtn.leftMargin = (int)(tx + (cx - dx)); lpBtn.topMargin = (int)(ty + (cy - dy)); btn.setLayoutParams(lpBtn); break; case MotionEvent.ACTION_UP: //开始预览 cameraHelper.openCamera(false); cameraHelper.startPreview(null); //必须设置为FALSE //sv.setZOrderOnTop(false); rlRoot.requestLayout(); break; } return false; } });当写完代码开始在设备上运行调试时, 出现了一个奇怪的问题:当系统显示导航栏时, 可以正常显示裁剪后的圆形, 在全屏或隐藏导航栏后, 裁剪失效了:要解决这个问题也简单, 只需要在**XRelativeLayout(rl)**中的SurfaceView上, 覆盖一个控件, 源码中已注释//MUST add view overlay rl.addView(new View(this));当然也可以增加到rlRoot中, 从上面的动图可以看到, 裁剪的有效范围与Button的位置有关.参考代码import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Path; import android.graphics.PixelFormat; import android.os.Bundle; import android.os.SystemClock; import android.view.MotionEvent; import android.view.SurfaceView; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.RelativeLayout; import android.app.Activity; public class CameraPreview extends Activity { int cameraId = 1; //根控件 RelativeLayout rlRoot; CameraHelper cameraHelper; SurfaceView sv; RelativeLayoutX rl; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); rlRoot = new RelativeLayout(this); //显示于SurfaceView 下方的ImageView ImageView iv = new ImageView(this); RelativeLayout.LayoutParams lpIv = new RelativeLayout.LayoutParams(UiTools.WRAP_CONTENT, UiTools.WRAP_CONTENT); iv.setScaleType(ImageView.ScaleType.FIT_XY); iv.setImageResource(R.drawable.ic_drawer_product_imgs); iv.setOnTouchListener(new View.OnTouchListener() { float cx, cy, dx, dy; int tx, ty; @Override public boolean onTouch(View v, MotionEvent event) { cx = event.getRawX(); cy = event.getRawY(); switch(event.getAction()){ case MotionEvent.ACTION_DOWN: dx = cx; dy = cy; tx = lpIv.leftMargin; ty = lpIv.topMargin; break; case MotionEvent.ACTION_MOVE: //同样有效 //btn.setTranslationX(tx + (cx - dx)); //btn.setTranslationY(ty + (cy - dy)); lpIv.leftMargin = (int)(tx + (cx - dx)); lpIv.topMargin = (int)(ty + (cy - dy)); iv.setLayoutParams(lpIv); break; } return true; } }); rlRoot.addView(iv, lpIv); //SurfaceView rl = new RelativeLayoutX(this); sv = new SurfaceView(this); //当未打开摄像头开始预览时, 显示透明(不设置则显示黑色) //sv.setZOrderOnTop(true); //sv.getHolder().setFormat(PixelFormat.TRANSLUCENT); rl.addView(sv, new RelativeLayout.LayoutParams(UiTools.MATCH_PARENT, UiTools.MATCH_PARENT)); cameraHelper = new CameraHelper(camBase.getParameters(cameraId), sv, camBase); rlRoot.addView(rl); //MUST add view overlay //rl.addView(new View(this)); RelativeLayout.LayoutParams lpBtn = new RelativeLayout.LayoutParams(UiTools.WRAP_CONTENT, UiTools.WRAP_CONTENT); Button btn = new Button(this); btn.setText("Show"); //设置输入监听, 用于拖动按键位置. btn.setOnTouchListener(new View.OnTouchListener() { float cx, cy, dx, dy; int tx, ty; @Override public boolean onTouch(View v, MotionEvent event) { cx = event.getRawX(); cy = event.getRawY(); switch(event.getAction()){ case MotionEvent.ACTION_DOWN: dx = cx; dy = cy; tx = lpBtn.leftMargin; ty = lpBtn.topMargin; break; case MotionEvent.ACTION_MOVE: lpBtn.leftMargin = (int)(tx + (cx - dx)); lpBtn.topMargin = (int)(ty + (cy - dy)); btn.setLayoutParams(lpBtn); break; case MotionEvent.ACTION_UP: //开始预览 cameraHelper.openCamera(false); cameraHelper.startPreview(null); //必须设置为FALSE //sv.setZOrderOnTop(false); rlRoot.requestLayout(); break; } return false; } }); rlRoot.addView(btn, lpBtn); setContentView(rlRoot); } @Override protected void onDestroy() { super.onDestroy(); cameraHelper.stopPreview(); } static class RelativeLayoutX extends RelativeLayout{ public RelativeLayoutX(Context context) { super(context); } Path path = new Path(); @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(w, h, oldw, oldh); path.reset(); path.addCircle(w/2f, h/2f, Math.min(w, h)/2f, Path.Direction.CW); } @Override protected void dispatchDraw(Canvas canvas) { //裁剪圆型画布,使SurfaceView显示圆形区域图像 canvas.save(); canvas.clipPath(path); super.dispatchDraw(canvas); canvas.restore(); } } //非关键代码, 主要用于返回打开摄像头预览的参数 CameraHelper.CameraBase camBase = new CameraHelper.CameraBaseSimple(){ @Override public CameraHelper.CameraParams getParameters(int camIndex) { return new CameraHelper.CameraParams(cameraId, 640, 480, 30, 0, 0); } @Override public boolean sameParams(CameraHelper.CameraParams cp) { return true; } @Override public void onPreviewStarted(int camIndex) {} @Override public void onCameraError(int error) {} }; }PS虽然提出了需求, 也实现了想要的效果, 却也留下了一个问题, 问题虽然解决, 但却找不到具体的原因!1.浮动窗的情况未测试过2.Dialog或其它弹出窗口未测试过3.setZOrderOnTop(true)的情况未有好的解决办法参考解决SurfaceView渲染的各种疑难杂症android 圆形相机预览拍照_Android相机（摄像头）圆形预览窗口，圆形SurfaceView

SHARED # Provides a relative path to your source file(s). jniapi.cpp ) # Searches for a specified prebuilt library and stores the path as a # variable. Because CMake includes system libraries in the search path by # default, you only need to specify the name of the public NDK library # you want to add. CMake verifies that the library exists before # completing its build. find_library( # Sets the name of the path variable. log-lib # Specifies the name of the NDK library that # you want CMake to locate. log ) # Specifies libraries CMake should link to your target library. You # can link multiple libraries, such as libraries you define in this # build script, prebuilt third-party libraries, or system libraries. target_link_libraries( # Specifies the target library. apitester # Links the target library to the log library # included in the NDK. ${log-lib} )扩展关于Studio 中创建JNI创建JNI比较简单: 模块名, 右键 > Add C++ to Module伴随而来的一些问题1. CMake中版本兼容问题, 更改为已安装的版本 3.10.2, 修改build.gradle和 CMakeLists.txt2. 创建后, 在Android视图下, 只有一个CPP文件夹其它的问题现象还有:打开CPP文件:android studio this file does not belong to any project target等.不管如何sync或增加/修改文件, 甚至重启Studio也不能解决, 始终看不到CPP目录下的文件.最后解决:找到项目目录下的setttings.gradle注释当前的模块 -> sync now 去掉模块注释 -> sync now3. 新增加JNI函数: 选中函数 ALT + ENTER之后会有一个文件选择列表, 选中想要添加的位置即可自动生成代码, 相当方便

RK356X Android 11 增加自定义系统服务调用失败
平台RK3566 + Android 11概述为方便第三方应用调用系统功能, 增加系统服务提权并提供应用层调用开放接口, 在Android 9及以下版本已实现基本的实现步骤如下, 服务以MyService命名:1.在frameworks/base/core中增加 IMyService.aidl2.增加IMyService接口实现的应用, 可以存放在frameworks/base/packages/MyService3.修改frameworks/base/services启动MyService, 并增加到SystemService中.4.修改相关SELinux权限.Android 11上的问题相同的补丁, 打到Android 11上, 出现了新的问题.2022-02-10 01:05:48.340 5010-5010/com.ansondroider.apitester W/oider.apiteste: Accessing hidden method Landroid/os/IMyService$Stub;->asInterface(Landroid/os/IBinder;)Landroid/os/IMyService; (blacklist, linking, denied) 2022-02-10 01:05:48.344 5010-5010/com.ansondroider.apitester W/oider.apiteste: Accessing hidden method Landroid/os/IMyService;->reboot(IIIIIII)Z (blacklist, linking, denied) 2022-02-10 01:05:48.346 5010-5010/com.ansondroider.apitester W/oider.apiteste: Accessing hidden method Landroid/os/IMyService;->shutdown(IIIIIII)Z (blacklist, linking, denied)这个问题出现在第三方应用调用接口时, 初始化接口类的过程中, 接口类需要通过调用 IMyService.Stub.asInterface来获取服务实现跨进程调用, LOG中体现为 找不到相关的类, 理论上, 也会影响反射的方式,翻阅了相关资料后, 原因可以查看文末参考内容,解决方法是将增加的接口添加到源码下的hiddenapi-greylist.txt中(不能有空行):frameworks/base/config/hiddenapi-greylist.txtLandroid/os/IMyService$Stub;->asInterface(Landroid/os/IBinder;)Landroid/os/IMyService; Landroid/os/IMyService;->reboot(IIIIIII)Z Landroid/os/IMyService;->shutdown(IIIIIII)Z重新编译打包, 完成!参考1.针对非SDK接口的限制-Google 反射限制2.Android 11 中有关限制非 SDK 接口的更新3.SystemServer 启动新增服务APK

Android Modbus 通讯实现
平台Android 8.1 + RK3288Windows 8.1 + Modbus Slave 7.31概述在RK3288的主板上, 支持一路RS485串口, 再将外设通过这路串口连接后, 就可以实现外设与3288的通讯, 由于手上没有外设, 所以采用模拟的方式.连方式如下:准备1.买了一个RS485 U转串, 京东2.Windows 上安装 Modbus Slave下载地址直接装, 压缩中已包含注册码.3.接线:只接2根线开始1.接好线后, 打开Modbus Salve, 并连接.一定要仔细核对串口的参数是否正确, 由于一开始选错了红框中的参数, 导致数据发送不过来, 主要的表现有: 数据不完整, 数据错误. 单独一个一个发正常, 连着发3个以上就出错参考: 串口通信校验方式（even，odd，space，mark)不管GOOGLE还是百度, 都没有人解释为什么Modbus Slave 数据接收不全, 这或许对熟悉的人来说并不算是问题的问题主要参考下Modbus测试工具ModbusPoll与Modbus Slave使用方法红框部分是在调试过程中, 把地址改成了1, 导致读取异常, 特此记录寄存器部分, 很简单, 点击可修改, 数据发生变化也同样会刷新.通俗点可以把它理解为数据库, 没有主动发送数据的功能或接口, 当通讯数据准确, 它会自动把寄存器的数据通过响应发过去.当然, 整个数据处理过程, 均按标准的Modbus协议来2.Android端的实现: 串口通讯实现方式大同小异, 比如Acccord/AndroidSerialPort和利用android-serialport-api进行串口读写操作final UartComm uart = new UartComm(); uart.open("/dev/ttyS0"); int r = uart.setOpt(9600, 8, 0, 1); //剩下读写的实现不作细述.3.ModBus 协议读寄存器SlaveId + Function + address + value + CRC如://读取从 0 开始的 1e(30)个数据 SEND->01 03 00 00 00 1e c5 c2 //返回数据 3C(60)为数据长度对应上面要求的30个, 一个数据2个byte RECV<-01 03 3c 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 7a d7写寄存器SlaveId + Function + address + value + CRC//把地址0a 的值改为 1a SEND->01 06 00 0a 00 1a 28 03 //成功后返回 RECV<-01 06 00 0a 00 1a 28 03写多个寄存器 功能码 0x10(16)SEND->01 10 00 1B 00 03 06 00 DF 00 BE 00 FF 23 47 RECV->01 10 00 1B 00 03 F0 0F更多说明请查阅: Modbus协议中文版.pdf若无法打开, 请自行下载Modbus协议中文版【完整版】.pdf

Android 7.0 SystemUI 状态/导航栏的隐藏与显示
平台Android 7.1 + RK3288概述从Android 4.4开始支持沉浸式全屏体验,在沉浸式全屏模式下,状态栏、 虚拟按键动态隐藏,应用可以使用完整的屏幕空间,按照 Google 的说法,给用户一种 “身临其境” 的体验。增加了 IMMERSIVE 和 IMMERSIVE_STICKY 标记,可以用这两个标记与 SYSTEM_UI_FLAG_HIDE_NAVIGATION 和 SYSTEM_UI_FLAG_FULLSCREEN 一起使用， 来实现沉 浸模式。全屏的是通过隐藏状态栏和导航栏实现, 服务之间的交互如下:关键函数frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java//顾名思义, 状态栏的控制器与导航栏的控制器, 设置显示/隐藏, 或临时显示都需要它 private final StatusBarController mStatusBarController = new StatusBarController(); private final BarController mNavigationBarController = new BarController("NavigationBar", View.NAVIGATION_BAR_TRANSIENT, View.NAVIGATION_BAR_UNHIDE, View.NAVIGATION_BAR_TRANSLUCENT, StatusBarManager.WINDOW_NAVIGATION_BAR, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, View.NAVIGATION_BAR_TRANSPARENT); //WindowManagerService调用 @Override public int adjustSystemUiVisibilityLw(int visibility) { mStatusBarController.adjustSystemUiVisibilityLw(mLastSystemUiFlags, visibility); mNavigationBarController.adjustSystemUiVisibilityLw(mLastSystemUiFlags, visibility); // Reset any bits in mForceClearingStatusBarVisibility that // are now clear. mResettingSystemUiFlags &= visibility; // Clear any bits in the new visibility that are currently being // force cleared, before reporting it. return visibility & ~mResettingSystemUiFlags & ~mForceClearedSystemUiFlags; } //更新FLAG用, 比如, 会获取APP的指定FLAG, 再与前面的控制器交互并更新当前的系统FLAG private int updateSystemUiVisibilityLw() { // If there is no window focused, there will be nobody to handle the events // anyway, so just hang on in whatever state we're in until things settle down.

前言Android的摄像头的功能扩展越来越丰富, 近段时间因为涉及到RTSP推送的需求, 稍微了解记录踩过的坑.服务端纯JAVA开发的服务端项目, 几年前用过, 时至今日, 依然好用.spydroid-ipcamera使用高阶说明如: 使用音频和视频->rtsp://xxx.xxx.xxx.xxx:8086?aac&h264客户端客户端, PC上建议用VLC, 在调试很方便, 功能也强大.手机端, 这个重点说说, 毕竟, 在几年前, 踩过较深的坑就是它:Awesome Open Source 从这里找到开源的项目然后, 尝试后的结果是:SmarterStreaming [x] 太大了, 下不下来, 没耐心…EasyPlayer-RTSP-Android [v] 需要申请APPID, 国内开源SDK的套路EasyPlayer-RTSP-Android-APK [v] 需要申请APPID, 国内开源SDK的套路RTSP.Player.Android [v] 最终采用这个, 效果也不错, 但兼容性没测过.延迟这是个老生常谈的问题手机端的VideoView/MeidaPlayer控件, 在播放后, 经常会发现有5秒的延迟在PC上使用VLC测试, 默认设置的情况下, 会在2秒左右最开始, 怀疑是服务端的问题, 折腾了不少时间, 只能说, 还是太年轻了VLC中连接的设置:缓存适当降低, 如, 把1000ms 改为200ms手机端, 就要找到好用的播放控件或工具RTSPPlayer: 这个项目, 曾经效果还不错, 只是最近测试发现, 经常连不上或连上后没图像或花屏, 接口中, 延时可以支持100ms左右.vlc-android: 怎么说呢, 强大, 但要很能折腾, 曾经下载并编译过, 最终出来的效果却不尽如人意(跟官方发布的APK表现不同)扩展图像格式转换Android YUV图像转换算法和检测工具YUV420P、YUV420SP、NV12、NV21和RGB互相转换并存储为JPEG以及PNG图片GIT clone失败$ git clone https://github.com/tsingsee/EasyPlayer-RTSP-Android.git 正克隆到 'EasyPlayer-RTSP-Android'... remote: Enumerating objects: 50, done. remote: Counting objects: 100% (50/50), done. remote: Compressing objects: 100% (29/29), done. error: RPC failed; curl 18 transfer closed with outstanding read data remaining fatal: The remote end hung up unexpectedly fatal: 过早的文件结束符（EOF） fatal: index-pack failedgit clone时RPC failed; curl 18 transfer closed with outstanding read data remaining

重装Ubuntu系统后Mysql 数据恢复历程
1.概况为服务器重装了Ubuntu 16.04-server, 之前的一些数据丢失了, 好在硬盘并未格式化, 至少还有点希望能恢复Mysql的数据2.现有条件把旧的硬盘挂载到电脑上, 找到数据库目录下的文件: 默认的数据库目录为: /var/lib/mysql硬盘挂载目录为: /media/user/f101a309-d55a-4a50-8e1c-d63534146b6f$ ll /media/user/f101a309-d55a-4a50-8e1c-d63534146b6f/var/lib/mysql -rw-r----- 1 122 vboxusers 56 9月 6 2019 auto.cnf -rw------- 1 122 vboxusers 1680 11月 19 06:09 ca-key.pem -rw-r--r-- 1 122 vboxusers 1112 11月 19 06:09 ca.pem -rw-r--r-- 1 122 vboxusers 1112 11月 19 06:09 client-cert.pem -rw------- 1 122 vboxusers 1676 11月 19 06:09 client-key.pem -rw-r--r-- 1 122 vboxusers 0 2月 25 09:40 debian-5.7.flag drwxr-x--- 2 122 vboxusers 4096 9月 17 2019 FactoryTest/ -rw-r----- 1 122 vboxusers 750 4月 1 09:07 ib_buffer_pool -rw-r----- 1 122 vboxusers 79691776 4月 1 09:07 ibdata1 -rw-r----- 1 122 vboxusers 50331648 4月 1 09:07 ib_logfile0 -rw-r----- 1 122 vboxusers 50331648 9月 6 2019 ib_logfile1 drwxr-x--- 2 122 vboxusers 4096 10月 22 15:27 kanboard/ drwxr-x--- 2 122 vboxusers 4096 2月 25 09:41 mysql/ -rw-r--r-- 1 122 vboxusers 6 2月 25 09:41 mysql_upgrade_info drwxr-x--- 2 122 vboxusers 4096 2月 25 09:40 performance_schema/ -rw------- 1 122 vboxusers 1676 11月 19 06:09 private_key.pem -rw-r--r-- 1 122 vboxusers 452 11月 19 06:09 public_key.pem -rw-r--r-- 1 122 vboxusers 1112 11月 19 06:09 server-cert.pem -rw------- 1 122 vboxusers 1680 11月 19 06:09 server-key.pem drwxr-x--- 2 122 vboxusers 12288 11月 19 06:09 sys/ drwxr-x--- 2 122 vboxusers 12288 10月 22 10:18 zentao/需要恢复的数据库 FactoryTest, 所以, 不管如何先将它压缩保存下来, 丢到服务器去试试先.3.粗暴的尝试停止mysql /etc/init.d/mysql stop直接把上面找到的文件丢到服务器对应的mysql目录下, 并修改相应的文件权限启动mysql /etc/init.d/mysql start尝试访问读取数据失败…果然没那么简单.停止数据库, 删除前面的暴力尝试拷贝进去的文件夹4.Google 后, 见参考.14.1恢复表格需要用到工具mysqlfrm找不到, 就装一个sudo apt install mysql-utilities命令执行的效果 mysqlfrm --diagnostic FactoryTest/Wifi.frm# WARNING: Cannot generate character set or collation names without the --server option. # CAUTION: The diagnostic mode is a best-effort parse of the .frm file. As such, it may not identify all of the components of the table correctly. This is especially true for damaged files. It will also not read the default values for the columns and the resulting statement may not be syntactically correct. # Reading .frm file for FactoryTest/Wifi.frm: # The .frm file is a TABLE. # CREATE TABLE Statement: CREATE TABLE `FactoryTest`.`Wifi` ( `id` int(11) NOT NULL AUTO_INCREMENT, `ssid` varchar(32) NOT NULL, `pwd` varchar(32) NOT NULL, PRIMARY KEY `PRIMARY` (`id`) ) ENGINE=InnoDB; #...done.表格的query语句出来了, 接下来就简单了, 拷贝粘贴, 执行完, 表格都有了.4.2恢复数据进mysql执行下面的命令(所有的表格):ALTER TABLE example_table DISCARD TABLESPACE;执行完后, 数据库目录下的 .idb 文件都不见了执行上面的暴力拷贝, 只拷贝 .idb 文件: sudo cp -rn . /var/lib/mysql/FactoryTest/记得修改文件权限: sudo chown mysql:mysql -R /var/lib/mysql/FactoryTest再进mysql为每个表格执行语句ALTER TABLE example_table IMPORT TABLESPACE;完成5.参考1.

mWidgetInfo = getSearchWidgetProvider(launcher); if (mWidgetInfo == null) { // There is no search provider, just show the default widget. return getDefaultView(inflater, container, false); } SharedPreferences prefs = Utilities.getPrefs(launcher); AppWidgetManagerCompat widgetManager = AppWidgetManagerCompat.getInstance(launcher); LauncherAppWidgetHost widgetHost = launcher.getAppWidgetHost(); InvariantDeviceProfile idp = LauncherAppState.getInstance().getInvariantDeviceProfile(); Bundle opts = new Bundle(); Rect size = AppWidgetResizeFrame.getWidgetSizeRanges(launcher, idp.numColumns, 1, null); opts.putInt(AppWidgetManager.OPTION_APPWIDGET_MIN_WIDTH, size.left); opts.putInt(AppWidgetManager.OPTION_APPWIDGET_MIN_HEIGHT, size.top); opts.putInt(AppWidgetManager.OPTION_APPWIDGET_MAX_WIDTH, size.right); opts.putInt(AppWidgetManager.OPTION_APPWIDGET_MAX_HEIGHT, size.bottom); int widgetId = prefs.getInt(QSB_WIDGET_ID, -1); AppWidgetProviderInfo widgetInfo = widgetManager.getAppWidgetInfo(widgetId); boolean isWidgetBound = (widgetInfo != null) && widgetInfo.provider.equals(mWidgetInfo.provider); if (!isWidgetBound) { // widgetId is already bound and its not the correct provider. // Delete the widget id. if (widgetId > -1) { widgetHost.deleteAppWidgetId(widgetId); widgetId = -1; } widgetId = widgetHost.allocateAppWidgetId(); isWidgetBound = widgetManager.bindAppWidgetIdSkipBindPermission(widgetId, mWidgetInfo, opts); if (!isWidgetBound) { widgetHost.deleteAppWidgetId(widgetId); widgetId = -1; } } if (isWidgetBound) { mQsb = (LauncherAppWidgetHostView) widgetHost.createView(launcher, widgetId, mWidgetInfo); mQsb.setId(R.id.qsb_widget); mQsb.mErrorViewId = R.layout.qsb_default_view; if (!Utilities.containsAll(AppWidgetManager.getInstance(launcher) .getAppWidgetOptions(widgetId), opts)) { try{ mQsb.updateAppWidgetOptions(opts); }catch(Exception e){ Log.v("QsbContainerView", "getQsbBar error "+e.getMessage()); return null; } } mQsb.setPadding(0, 0, 0, 0); return mQsb; } // Return a default widget with setup icon. return getDefaultView(inflater, container, true); }这段代码的问题在于int widgetId = prefs.getInt(QSB_WIDGET_ID, -1);, widgetId一直是 -1.widgetId = widgetHost.allocateAppWidgetId();申请了一个ID, 并调用bindAppWidgetIdSkipBindPermission, 在这个操作完成后, system/users/0/appwidgets.xml 就增加了一行.而后, 在SearchWidgetProvider就得处理多一次, 在几千次后, 时间就不是那么容易忽略的问题了.后话这个问题在RK3288上面也同样存在
