Android应用生死轮回的那些事儿(6) - 武器库完结篇

资源相关API

这些API虽然数量众多，但是功能相对简单，都是根据包头或者是ApplicationInfo或Activity信息去获取一些资源，如图标，文本等。

Android 1.0创始API

• getXml：获取xml
• getText:从资源中读取文本
• getResourcesForApplication(app)：获取资源对象
• getResourcesForApplication(appPackageName)：获取资源对象
• getResourcesForActivity：从Activity中获取资源对象
• getDrawable：获取Drawable
• getDefaultActivityIcon:Activity的默认Icon
• getApplicationLabel:获取Applicaiton的标签
• getApplicationIcon：获取图标
• getActivityIcon：获取图标

Android 2.3新增API

Android 2.3新增两个API，都是跟Logo相关。

• getApplicationLogo
• getActivityLogo

Android 4.4手表版新增API

手表上新增了Banner.

• getApplicationBanner
• getActivityBanner

Android 5.0新增API

Android 5.0新增了UserBadged UI，所以新增了三个方法：

• getUserBadgedLabel
• getUserBadgedIcon
• getUserBadgedDrawableForDensity

禁掉或者解禁相关API

Android中可以支持将应用或者组件禁掉或者解禁。
ComponentEnableSetting是通过组件名来设置，ApplicationEnableSetting是通过包名。

• setComponentEnabledSetting
• getComponentEnabledSetting
• setApplicationEnabledSetting
• getApplicationEnabledSetting

setApplicationEnabledSetting

原型：

void setApplicationEnabledSetting (String packageName, int newState, int flags)

参数：

• 包名
• 新状态：状态请见下面的3种。
• 标志位：要么是DONT_KILL_APP，要么是0.

状态可以为：

• COMPONENT_ENABLED_STATE_ENABLED
• COMPONENT_ENABLED_STATE_DISABLED
• COMPONENT_ENABLED_STATE_DEFAULT

例程：禁掉微信：

    public void testSetApplicationEnableSetting() {
        mPm.setApplicationEnabledSetting("com.tencent.mm", PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                PackageManager.DONT_KILL_APP);
    }

setComponentEnabledSetting

将包中的四大组件之一禁掉或解禁。

原型：

void setComponentEnabledSetting (ComponentName componentName, int newState, int flags);

参数与上面的针对整个应用的一致。

检查签名

Android 1.0时，只能检查两个包名的签名是否一致。

原型：

int checkSignatures (String pkg1, String pkg2);

到了Android 2.0，也可以支持对两个uid之间判断签名。
问题是，从包名获取uid的API，要到Android 7.0才有呢。。。

原型：

int checkSignatures (int uid1, int uid2);

Prefer相关

addPackageToPreferred API已经在Android 2.1被除名，所以Prefer相关的API，只剩下下面三个：

• getPreferredPackages
• getPreferredActivities
• clearPackagePreferredActivities

至此，Android 1.0的PackageManager提供的46个API全部讲完了。

feature相关API

Android 2.0开始引入feature的概念。我们可以通过getSystemAvailableFeatures方法获取系统支持哪些feature. 或者是通过hasSystemFeature(name)方法判断是否支持一个feature.
不过，Android 2.0的时候，feature是不分版本号的。支持版本号的或者是通过hasSystemFeature方法要到Android 7.0才会出品。

FeatureInfo类

属性：

• flags: FLAG_REQUIRED或0
• name:属性名
• reqGlEsVersion:在name为空时，为需要的OpenGL ES的版本号
• version:(Android 7.0才有)版本号

方法：

• getGlEsVersion(): 0x00010002代表1.2

getSystemAvailableFeatures

原型：

FeatureInfo[] getSystemAvailableFeatures ();

例程：

    public void testGetSystemAvailableFeatures(){
        final FeatureInfo[] fis = mPm.getSystemAvailableFeatures();
        if(fis!=null){
            for(FeatureInfo fi:fis){
                Log.d(TAG,"Feature Info:"+fi.toString());
            }
        }
    }
