public class MyReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        String action = intent.getAction();        if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {            Log.e("包被安装了", "包名是" + intent.getData());        } else if (Intent.ACTION_PACKAGE_REMOVED.equals(action)) {            Log.e("包被卸载的", "包名是" + intent.getData());        }    }    public MyReceiver() {    }}

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