  • 0

I have a BroadcastReceiver that listen for the “SMS_SENT” Intent after an SMS has been sent. As far as I know, SMSManager does provide a wakelock so that it can actually send the SMS (I don’t have any proof of this, but common sense would tell me that this is the case).

However, my BroadcastReceiver calls a WakefulIntentService, which uses its own wakelock, so that is ok. However, what about the receiver itself? Do I need to create a new wakelock so that I can guarantee that the WakefulIntentService is called? Or can I just safely ignore this, just like one can do with a receiver for AlarmManager?

Thanks

    Once your receiver calls WakefulIntentService.sendWakefulWork(), the WakefulIntentService engine acquires a WakeLock.

    So long as you are not doing much work before that call, you should be fine.
