Starting multiple Services with the same Intent but different requestCode uses same Object

Issue

I have an object that schedules a service through the AlarmManager like this:

public void schedule(MyEnum enum) {
    Intent intent = new Intent(context, MyService.class);
    intent.setAction(enum.name());

    Bundle args = new Bundle();
    args.putSerializable("MyEnum", content);
    intent.putExtra("Bundle", args);

    PendingIntent pendingIntent = PendingIntent.getService(context, enum.ordinal(),
        intent, 0);  
    alarmManager.set(AlarmManager.RTC_WAKEUP, 0, pendingIntent);
}

The service:

public class MyService extends IntentService {
    @Override
    public void onHandleIntent(Intent intent) {
        Log.d("this: " + this);
    }
}

The way I start the scheduler:

scheduler.schedule(MyEnum.ONE);
scheduler.schedule(MyEnum.TWO);

And What I see in the logs:

MyService@41ea7858
MyService@41ea7858

I tried using a BroadcastReceiver, I also played with the flags, but same result. Then I tried something like that:

button1.setOnClickListener() { scheduler.scheduler(MyEnum.ONE); }
button2.setOnClickListener() { scheduler.scheduler(MyEnum.TWO); }

And if I click on button1 then button2 right away, I see the same Id in the logs. But if I leave a bit more time between the clicks, I get two different Ids...

Any idea what's going on and how to avoid that? Thanks!

Solution

You can not.

Services and BroadcastReceivers are different from Activities in such a way, that there can only be one instance at the same time.
Only when the first instance is destroyed, a new is created. That's what you experience with your second experiment.
