AlarmManager gets killed on app destroy

Question

I have the following problem: I register my alarm manager in onCreate, It gets executed each minute now. However if i kill the app via the Android taskmanager (so the app state is destoyed) the AlarmReceiver stops excecuting. Why?

My Code:

AlarmReceiver

public class AlarmReceiver extends WakefulBroadcastReceiver {

private AlarmManager mAlarm;
private PendingIntent mAlarmIntent;

@Override
public void onReceive(Context context, Intent intent) {
    Intent service = new Intent(context, PortalPullService.class);

    startWakefulService(context, service);
}

public void setAlarm(Context context) {
    mAlarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
    mAlarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

    int interval = context.getResources().getInteger(R.integer.update_interval_in_mins) * 60 * 1000;

    mAlarm.setInexactRepeating(
            AlarmManager.ELAPSED_REALTIME_WAKEUP,
            SystemClock.elapsedRealtime() + interval,
            interval,
            mAlarmIntent);

    ComponentName reciever = new ComponentName(context, AlarmBootReceiver.class);
    PackageManager pm = context.getPackageManager();

    pm.setComponentEnabledSetting(reciever,
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);
}

public void cancelAlarm(Context context) {
    if(mAlarm != null) {
        mAlarm.cancel(mAlarmIntent);
    }

    ComponentName reciever = new ComponentName(context, AlarmBootReceiver.class);
    PackageManager pm = context.getPackageManager();

    pm.setComponentEnabledSetting(reciever,
            PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
            PackageManager.DONT_KILL_APP);
}
}

PullService

public class PortalPullService extends IntentService {

private static final String LOG_TAG = "PortalPullService";

public PortalPullService() {
    super(LOG_TAG);
}

@Override
protected void onHandleIntent(Intent intent) {


    //TODO make request to ** check if new Infos are available, then send notification

    Helper.sendNotification(this, "Test", "Testnotification"); //My test if this works

    AlarmReceiver.completeWakefulIntent(intent);
}

}

AndroidManifest.xml

<receiver android:name=".PortalUpdate.AlarmReceiver" />

<service
        android:name=".PortalUpdate.PortalPullService"
        android:exported="false" />   

The receiver gets registered via new AlarmReceiver().setAlarm(this);

I searched on sveral SO questions, but i can't find an answer... I don't know where is my fault...

Thanks in advance ;)

Okay it's a problem to install a debug version of your app on Huawei.

Because you can disable Background Services in Huawei, and Huawei doesn't recognize a debug version of your app as a proper app, it destroys all services maybe cause of security reasons ...

Installing it properly over Play Store helps!
