There are currently few issues logged around this bug: http://code.google.com/p/android/issues/detail?id=3953
I don't know your specific case, but was easy to fix in my case, when I made sure that the dialogs/views/adapters that were being created are with the right context/activity. Pressing a back button usually finishes the activity, so if you have created for discussion sake created an static ListAdapter and passed it (this), an activity instance, this static adapter can no longer be used for showing dialogs etc. with the previous contexts. This behaviour gets complex depending on the launch modes/flags you set when starting an activity, and also whether you handle back button events. So "token android.os.binderpr...@431d28f0 is not valid; is your activity running? " means your activity instance is no longer in History stack, but your are trying to use it somewhere. Since there is no knowing when your activity got finished and the sequence of steps that caused it, depending on different modes, you get sporadic reports. -Chander On Nov 22, 1:23 pm, Mariano Kamp <[email protected]> wrote: > Hey, > > I sporadically get bug reports with a BadTokenException. > > As I don't see my app in the stacktrace I am wondering how to find the > cause of this?
