Hallo, ich versuche, die installierte Anwendung zu erkennen, damit ich einige Analysen für die Anwendung durchführen kann. Ich verwende dieses Beispiel, das ich im Stackoverflow gefunden habe, um nach Paketinstallationen aus meiner aktuellen Anwendung zu suchen, aber in meinem Logcat passiert nichts.

void registerReceiver() {
    IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
    filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
    filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
    filter.addDataScheme("package");

}

public void onReceive(Context context, Intent intent) {
    String actionStr = intent.getAction();
    if (Intent.ACTION_PACKAGE_ADDED.equals(actionStr)) {
        Uri data = intent.getData();
        String pkgName = data.getEncodedSchemeSpecificPart();
        //handle package adding...
        Log.i("Logging Service", pkgName);

    }

}

<receiver android:name="RealTimeActivity">
    <intent-filter>
   <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.PACKAGE_ADDED"  />
    <action android:name="android.intent.action.PACKAGE_CHANGED" />
    <action android:name="android.intent.action.PACKAGE_INSTALL" />
    <action android:name="android.intent.action.PACKAGE_REMOVED" />
    <action android:name="android.intent.action.PACKAGE_REPLACED" />
    </intent-filter>
 </receiver>
