I would like to ask for some example, where two different activities (button in first activity open second activity), are communicating with one service (AIDL, etc.)
I\'ve tried
Each Activity is responsible for binding and unbinding from the Service. This is normally done in onResume / onPause, or onStart / onStop, depending on your requirements. One Activity cannot bind another Activity to a Service. That's just the way it is. :)
