Android alarms, service as not been called

Question

In my activity:

Intent myIntent = new Intent(this, MyAlarmService.class);
pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

Toast.makeText(this, "Start Alarm", Toast.LENGTH_LONG).show();

The class to be called:

public class MyAlarmService extends Service {

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        Toast.makeText(this, "MyAlarmService.onCreate()", Toast.LENGTH_LONG).show();
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        Toast.makeText(this, "MyAlarmService.onBind()", Toast.LENGTH_LONG).show();
        return null;
    }

    @Override
    public void onStart(Intent intent, int startId) {
        // TODO Auto-generated method stub
        super.onStart(intent, startId);
        Toast.makeText(this, "MyAlarmService.onStart()", Toast.LENGTH_LONG).show();
    }
}

With this code, MyAlarmService as not been called. Why? This code removed from a sample, which therefore tested is functioning correctly. Will I have forgotten anything?

Answer 1

I think, your service is started properly. There is problem with Toast in service.

Try to change Toast.makeText() to Log.d() and see if record appears in your Logcat.

Problem with Toast in service has been explained here.

Answer 2

It seems to be right. I also tried this example in my code and it worked fine.

I think the problem is in the Manifest. You need to declare the service in the Manifest of your project like this:

< service android:name=".MyAlarmService" />
