问题
I am doing Android Wear project. Notification is displayed to user with contentAction, so user can tap it. After taping it SomeActivity is displayed with DelayedConfirmationView giving user time to cancel upcoming API request. When DelayedConfirmationView finish API call is made. After API call succeeds ConfirmationActivity is shown. When ConfirmationActivity returns we finish() SomeActivity and cancel the notification.
The problem I face is that after SomeActivity starts it is mysteriously stopped without a reason. The log together with the crash looks like follows:

I was trying many things to make it working but nothing really worked. Any ideas? Can DelayedConfirmationView cause such a misbehaviour? I saw examples in the Net and they start it even in onCreate, so it cannot be it.
What bothers me most is that there is onStop called before onPause. This is very strange. In the SomeActivity you can see that in onStop I disconnect from the GoogleApiClient but Activity is still alive, because logs shows that it tries to call API 3 seconds after activity was started (3 seconds take DelayedConfirmationView to finish). The problem is that this activity is not displayed to the user since mysterious onStop was called.

Looks like latest OS update solved the issue.
