活动堆栈自动清除？

Question

I have classes A, B, C, D; and they are done one after the other. When i get to class D then hit the back button it goes to class B (class C i have as a not history in the manifest) but instead of staying on class B from D, it goes back to class A after about a second all by itself.

why would it do that, how would you even debug something like that because the logcat does not say anything when it happens.

any suggestions?

Answer 1

I'd write some Log.d code like:

Log.d("MY_TAG", "Activity A, BC or D onCreate");

in every activity's onStart(), onCreate(), onResume(), onPause(), onStop() and on Destroy()

Then filter the logcat on MY_TAG

and see if that helps you track it down.
