For some time, Android Studio doesn\'t show me stacktrace when developed application crashes. All I can see is following line:
06-09 16:12:36.875 26037-2603
The same thing started happening to me after I updated my Android Studio. After hours of frustration, I found out that clicking on the Filter dropdown menu on the right side of the logcat screen and clicking on No Filters, even if it's already set to No Filters, fixes the issue. I don't know if it will work in your case but you might as well give it a try if you haven't already.
