What happens when you try to attach the debugger? Also what do you mean by kill the demo process debugger works as well? Sorry not sure what you're describing here.

@gpx1000 When I try to attach to the debugger, AS show me an error and tell me to close other adb, then the choose process dialog dismisses. After I kill the demo process, the AS debugger works and the choose process dialog doesn't dismiss as well.

Hmm... I'm not seeing this problem, and am not certain I understand what's happening. Can you please provide some logs? Perhaps that will point me in the direction to help diagnose what's happening here.
