OK Mike, so reading carefully through your explanation, it looks to me that the process you want is this:
A -> B -> C -> A -> (app close) Whilst what you are actually getting, with your current code, is this: A -> B -> C -> A -> A -> B -> (unknown) The complex nature of your activity jumping suggests that the code is simply too complex. I suggest you replace all the onKeyDown() and startActivityForResult() handling for something like this: ---------------- Activity A ---------------- // This code goes in the correct method of Activity A to start Activity B startActivity(new Intent(ActivityA, ActivityB)); ---------------- Activity B ---------------- // This code goes in the correct method of Activity B to start Activity C startActivity(new Intent(ActivityB, ActivityC)); // Set the "noHistory" attribute for Activity B in your AndroidManifest.xml <activity android:name="ActivityB" android:noHistory="true">...</activity> ---------------- Activity C ---------------- // This code goes in the correct method of Activity C to jump back to Activity A finish(); The outcome should be the navigation you are looking for. Activity B is skipped when you press the back button from Activity C. Pressing the back button again will close the application.
