Ich habe versucht zu erkennen, wann der Benutzer eine Anwendung auf seinem Gerät startet.

So fand ich diese Lösung:

https://stackoverflow.com/a/7239840/833219

Ich habe diesen Code in einen Thread eingefügt. Meine Anwendung erhält das Protokoll alle 3 Millisekunden, aber ich kann den Unterschied zwischen den Protokollen nicht feststellen, sodass ich nicht feststellen kann, welcher Code für den Start der Anwendung des Benutzers vorgesehen ist.

Hier ist ein Beispiel für das Protokoll, das ich beim Hinzufügen dieser Zeile erhalten habe:

String w = log.toString();
Log.i("LockService","w ="+w);

Wie kann ich anhand dieses Codes feststellen, dass der Benutzer eine Anwendung gestartet hat?
