The idea is very simple. Whenever an user comes back to my app from the Recents I want to show a simple dialog prompting with the password.<

Implement Application.ActivityLifecycleCallbacks, that will provide all activity callback in your application class.

public class AppController extends Application implements  
Application.ActivityLifecycleCallbacks  
{   
    @Override
    public void onCreate() {
        super.onCreate();
        registerActivityLifecycleCallbacks(this);

    }


    @Override
    public void onActivityCreated(Activity activity, Bundle bundle) {

    }

    @Override
    public void onActivityStarted(Activity activity) {

    }

    @Override
    public void onActivityResumed(Activity activity) {

    }

    @Override
    public void onActivityPaused(Activity activity) {

    }

    @Override
    public void onActivityStopped(Activity activity) {

    }

    @Override
    public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {

    }

    @Override
    public void onActivityDestroyed(Activity activity) {

    }
}
