Question

My app contains 3 activitys: A1, A2 and A3.

There is a “loop” between these activitys:
A1–starts–> A2 –starts–> A3 –starts–> A1 and so on.

Furthermore it’s possible to go back from A3 to A2 and from A2 to A1 (only these 2 cases)

My Problem is, that my App becomes very sluggish after clicking through the activitys. I think its because the activitys aren’t closed correctly. I can’t finish the activitys A1 and A2 after starting the next one, because it’s (how i said) possible to go back.

How can i handle this problem?

Thanks

Answer 1

When you are at Activity A3 and want to launch Activity A1 again then do..

intent = new Intent(getApplicationContext(), ActivityA1.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(intent);

It would clear the stack and would relaunch the Activity A1
