Hi Dianne,
Thank you for this. It's working well with one half of the application, but I'm
having trouble with going back to the other half.
For example:
Area A
Activities 1 2 3 4 5
Area B
Activities 6 7 8 9
The application starts in Area A Activity 1. If I navigate to 6 => 7 => 8 => 1
=> 2 then navigate to Area B I am at 8 which is perfect.
However, when I try to go back to Area B, I end putting Activity 1 on the stack
(so if I hit the back button I go back to 2).
I was hoping I could simply group the Activities by using
android:taskAffinity=".otherstuff" alone but I'm probably misunderstanding the
flag or setting up the Intent incorrectly.
The intents I'm using (to move between Areas) are:
(to go to Area B)
i = new Intent(this, B.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
(to go to Area A)
i = new Intent(this,A.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
I feel like it's really close and was wondering if you (or someone) can see
where I might be going wrong.
Regards,
Julius.
