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.
Cheers,
Sean
