Answer 1

• Create receiver for

  <receiver android:name=".PackageReceiver" android:enabled="true" android:exported="true"> <intent-filter> <action android:name="android.intent.action.PACKAGE_ADDED"/> <action android:name="android.intent.action.PACKAGE_CHANGED"/> <action android:name="android.intent.action.PACKAGE_REMOVED"/> <category android:name="android.intent.category.DEFAULT"/> <data android:scheme="package"/> </intent-filter> </receiver>

• In OnReceive() get action by intent.getAction()
  get package by intent.getData().getSchemeSpecificPart()

Answer 2

包名称在您从BroadcasReceiver获得的Intent中有，使用“ getData（）”函数，其中有已安装/未安装的包的ComponentName 。

Answer 3

Firstly get ComponentName in the way you are getting. After that get ApplicationInfo instance

PackageManager pm = context.getPackageManager();
ApplicationInfo appInfo = pm.getApplicationInfo(componentName.getPackageName(), 0);

Now get package name as appInfo.packageName. check here
