You don't need a thread *just* to schedule an event. There is an easier way, which should also fit your number of activities better.
1 - This needs to be done in the code for each of your activities. Use a base class, or a delegate object. 2 - In onCreate, make a Handler object with an anonymous inner Callback (just like for setOnClickListener). http://developer.android.com/reference/android/os/Handler.html#Handler(android.os.Handler.Callback ) 3 - Define a "what" constant for a special message, which will be used by this Handler. Doesn't have to be a system-wide unique, in fact a zero will do. 4 - When you want to schedule a delayed task, do this: mHandler.sendEmptyMessageAtTime or mHandler.sendEmptyMessageDelayed with the "what" constant defined above. http://developer.android.com/reference/android/os/Handler.html#sendMessageAtTime(android.os.Message, long) 5 - In the handler's callback, check the "what" of the message, and do whatever needs to be done. 6 - In the activity's onPause or onStop, call this to remove all pending messages with that "what" value from the event queue: http://developer.android.com/reference/android/os/Handler.html#removeMessages(int ) If the operation you're going to perform needs an argument, obtain a message using this: http://developer.android.com/reference/android/os/Handler.html#obtainMessage(int, java.lang.Object) and post with this: http://developer.android.com/reference/android/os/Handler.html#sendMessageAtTime(android.os.Message, long) or sendMessageDelayed -- Kostya 2011/6/11 Droid <rod...@gmail.com> > Thanks for your sensible suggestion.
