WIN DEATH error in Android?

Question

Sometimes, my application is frozen and after that it is crashed.

I read the system logs and I saw some error on my Activity as "WIN DEATH" at last lines of the system logs.

Someone can tell me the reason and show me the solve?

Thank you so much!

Here is system logs:

Thank you!

Answer 1

Your app is probably killed due to the ANR (Application Not Responding). That may happen when you do some hard processing in the UI thread. You can read more here: http://developer.android.com/guide/practices/responsiveness.html

There is only one solution: move all the hard work into the background thread so the UI thread will stay responsive.
