How clear the back stack activities on press of back Key in android

I have an android application where there are 3 activities:

MA – MainActivity (Launched when the application is started) AC1 – Activity1 – declared as androidLaunchMode=”singleInstance” AC2- Activity2- declared as androidLaunchMode=”singleInstance”

Initial flow of activities is MA -> AC1 Go back to MA MA -> AC2

So the total flow is like MA -> AC1 -> MA -> AC2 Now when I press back I want the flow to be AC2 -> MA to close application.

So, on back press of MA I want to clear the back stack of activities. So, how to I handle this in onKeyDown() of MA?

While you are calling MA from AC1 put below flag as intent

FLAG_ACTIVITY_REORDER_TO_FRONT

and

FLAG_ACTIVITY_CLEAR_TOP
