You have no activity. That's the point. Most medication dosing is on a 24-hour basis -- you take the pills/drops/leeches once per day. The odds of your activity existing at the point in time the 24-hour alarm goes off are negligible. Even if the user had been visiting your application relatively recently, Android terminates processes to free up RAM as it goes along. You must not assume that you have an activity. Hence, when the alarm goes off, if you want to pop up an activity, you need to start one with startActivity(). If you are concerned about there then possibly being *two* instances of your activity, add FLAG_ACTIVITY_CLEAR_TOP and FLAG_ACTIVITY_SINGLE_TOP to the Intent you use with startActivity(). If you do have an existing instance of this activity, it will come to the foreground and be called with onNewIntent(); otherwise, a new instance will be created as normal. I recommend that you also give the user an option for a Notification instead of popping up an activity. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, One Low Price! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
