android: AlarmManager and activity life cycle

I decided to write simple alarm clock (using AlarmManager). When alarm works out I want to show simple dialog with 2 buttons: OK and Snooze. So I have a question: what should I connect with my Pending Intent? I mean Service, Activity or BroadcastReceiver? At present version I use BroadcastReceiver where I start Activity that shows the dialog. I start it with flag FLAG_ACTIVITY_NEW_TASK. In onStrat() method I start music serv开发者_C百科ice. When OK button's pressed I call finish() for activity and stop music. In OnPause() I call finish() also. I do it because if two alarms run simultaneously then according to activity life cycle method onPause() will be called. It works... but sometime the music starts for a few seconds then finishes....then start again and finishes and so on. Why? Thanks.

Probably an activity in this case. Theme your activity to look the way you want (e.g., Theme.Dialog) rather than fussing around with a regular dialog box.

It is impossible to answer this question with the information you have supplied, sorry.
