RK3128 Android 7 BOX SDK 修改为MID界面-近期任务

简介: RK3128 Android 7 BOX SDK 修改为MID界面-近期任务

前文


RK3128 Android 7 BOX SDK 修改为MID界面


一文中已经调整好了Launcher和SystemUI, 满足日常调试使用.


新的问题


近期任务中的任务不能拖动, 只能用于切换, 这也就导致APP开发的调试中不能通过近期任务来结束后台应用.

跟踪


先看下当前的窗口信息: dumpsys window


Window #2 Window{a225ed0 u0 com.android.systemui/com.android.systemui.recents.tv.RecentsTvActivity}:
    mDisplayId=0 stackId=0 mSession=Session{a14766e 567:u0a10013} mClient=android.os.BinderProxy@d5ffe93
    mOwnerUid=10013 mShowToOwnerOnly=true package=com.android.systemui appop=NONE
    mAttrs=WM.LayoutParams{(0,0)(fillxfill) sim=#110 ty=1 fl=#83810500 pfl=0x24000 fmt=-2 wanim=0x103046c vsysui=0x700 needsMenuKey=2}

    mHasSurface=true mShownPosition=[0,0] isReadyForDisplay()=true hasSavedSurface()=false mWindowRemovalAllowed=false
    WindowStateAnimator{8110ee7 com.android.systemui/com.android.systemui.recents.tv.RecentsTvActivity}:
      Surface: shown=true layer=21010 alpha=1.0 rect=(0.0,0.0) 800.0 x 480.0

  mCurConfiguration={1.0 ?mcc?mnc [zh_CN] ldltr sw480dp w800dp h408dp 160dpi nrml land television -touch qwerty/v/h dpad/v s.5}
  mHasPermanentDpad=true
  mCurrentFocus=Window{a225ed0 u0 com.android.systemui/com.android.systemui.recents.tv.RecentsTvActivity}
  mFocusedApp=AppWindowToken{bfafe91 token=Token{b49c71b ActivityRecord{6dbfd2a u0 com.android.systemui/.recents.tv.RecentsTvActivity t18}}}


mCurrentFocus=Window{a225ed0 u0 com.android.systemui/com.android.systemui.recents.tv.RecentsTvActivity}

可知当前的窗口是RecentsTvActivity.


而期望使用的是:

mCurrentFocus=Window{7d2bd75 u0 com.android.systemui/com.android.systemui.recents.RecentsActivity}


Recent的分水领


frameworks/base/packages/SystemUI/src/com/android/systemui/recents/Recents.java


@Override
    public void start() {
        sDebugFlags = new RecentsDebugFlags(mContext);

        UiModeManager uiModeManager = (UiModeManager) mContext.
                getSystemService(Context.UI_MODE_SERVICE);
        if (uiModeManager.getCurrentModeType() == Configuration.UI_MODE_TYPE_TELEVISION) {
            mImpl = new RecentsTvImpl(mContext);
        } else {
            mImpl = new RecentsImpl(mContext);
        }
        ...
    }


public class RecentsTvImpl extends RecentsImpl{
    public final static String RECENTS_TV_ACTIVITY =
            "com.android.systemui.recents.tv.RecentsTvActivity";

    private final static String TAG = "RecentsImpl";
    // The minimum amount of time between each recents button press that we will handle
    private final static int MIN_TOGGLE_DELAY_MS = 350;
    // The duration within which the user releasing the alt tab (from when they pressed alt tab)
    // that the fast alt-tab animation will run.  If the user's alt-tab takes longer than this
    // duration, then we will toggle recents after this duration.
    private final static int FAST_ALT_TAB_DELAY_MS = 225;
    public final static String RECENTS_PACKAGE = "com.android.systemui";
    public final static String RECENTS_ACTIVITY = "com.android.systemui.recents.RecentsActivity";
}


取决于uiModeManager.getCurrentModeType() == Configuration.UI_MODE_TYPE_TELEVISION

frameworks/base/services/core/java/com/android/server/UiModeManagerService.java


@Override
    @Override
    public void onStart() {
        final Context context = getContext();
        final PowerManager powerManager =
                (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        mWakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, TAG);
        context.registerReceiver(mDockModeReceiver,
                new IntentFilter(Intent.ACTION_DOCK_EVENT));
        context.registerReceiver(mBatteryReceiver,
                new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
        mConfiguration.setToDefaults();
        final Resources res = context.getResources();
        mDefaultUiModeType = res.getInteger(
                com.android.internal.R.integer.config_defaultUiModeType);
        mCarModeKeepsScreenOn = (res.getInteger(
                com.android.internal.R.integer.config_carDockKeepsScreenOn) == 1);
        mDeskModeKeepsScreenOn = (res.getInteger(
                com.android.internal.R.integer.config_deskDockKeepsScreenOn) == 1);
        mEnableCarDockLaunch = res.getBoolean(
                com.android.internal.R.bool.config_enableCarDockHomeLaunch);
        mUiModeLocked = res.getBoolean(com.android.internal.R.bool.config_lockUiMode);
        mNightModeLocked = res.getBoolean(com.android.internal.R.bool.config_lockDayNightMode);
        final PackageManager pm = context.getPackageManager();
        mTelevision = pm.hasSystemFeature(PackageManager.FEATURE_TELEVISION)
                || pm.hasSystemFeature(PackageManager.FEATURE_LEANBACK);
        mWatch = pm.hasSystemFeature(PackageManager.FEATURE_WATCH);
        final int defaultNightMode = res.getInteger(
                com.android.internal.R.integer.config_defaultNightMode);
        mNightMode = Settings.Secure.getInt(context.getContentResolver(),
                Settings.Secure.UI_NIGHT_MODE, defaultNightMode);
        // Update the initial, static configurations.
        synchronized (this) {
            updateConfigurationLocked();
            sendConfigurationLocked();
        }
        publishBinderService(Context.UI_MODE_SERVICE, mService);
    }
    private void updateConfigurationLocked() {
        int uiMode = mDefaultUiModeType;
        if (mUiModeLocked) {
            // no-op, keeps default one
        } else if (mTelevision) {
            uiMode = Configuration.UI_MODE_TYPE_TELEVISION;
        } else if (mWatch) {
            uiMode = Configuration.UI_MODE_TYPE_WATCH;
        } else if (mCarModeEnabled) {
            uiMode = Configuration.UI_MODE_TYPE_CAR;
        } else if (isDeskDockState(mDockState)) {
            uiMode = Configuration.UI_MODE_TYPE_DESK;
        }
        if (mNightMode == UiModeManager.MODE_NIGHT_AUTO) {
            if (mTwilightManager != null) {
                mTwilightManager.registerListener(mTwilightListener, mHandler);
            }
            updateComputedNightModeLocked();
            uiMode |= mComputedNightMode ? Configuration.UI_MODE_NIGHT_YES
                    : Configuration.UI_MODE_NIGHT_NO;
        } else {
            if (mTwilightManager != null) {
                mTwilightManager.unregisterListener(mTwilightListener);
            }
            uiMode |= mNightMode << 4;
        }
        if (LOG) {
            Slog.d(TAG,
                "updateConfigurationLocked: mDockState=" + mDockState
                + "; mCarMode=" + mCarModeEnabled
                + "; mNightMode=" + mNightMode
                + "; uiMode=" + uiMode);
        }
        mCurUiMode = uiMode;
        if (!mHoldingConfiguration) {
            mConfiguration.uiMode = uiMode;
        }
    }


有两个地方决定了UI模式:


1.config_defaultUiModeType, 在overlay中值为4, 默认改为1.

frameworks/base/core/res/res/values/config.xml

device/rockchip/common/tv/overlay/frameworks/base/core/res/res/values/config.xml


<!-- Control the default UI mode type to use when there is no other type override
         happening.  One of the following values (See Configuration.java):
             1  UI_MODE_TYPE_NORMAL
             4  UI_MODE_TYPE_TELEVISION
             5  UI_MODE_TYPE_APPLIANCE
             6  UI_MODE_TYPE_WATCH
         Any other values will have surprising consequences. -->
    <integer name="config_defaultUiModeType">1</integer>


2.UiModeManagerService mTelevision

mTelevision = pm.hasSystemFeature(PackageManager.FEATURE_TELEVISION)
                || pm.hasSystemFeature(PackageManager.FEATURE_LEANBACK);


在PakcageManager中:


public static final String FEATURE_TELEVISION = "android.hardware.type.television";


进一步确认中主板中的内容:

cat /system/etc/permissions/tv_core_hardware.xml
