I keep getting a notification Buglog.txt. This happens this happens twice a day .The error log is 15mb. When I run alogcat I keep getting
D/AbsListView(19983):unregister IRListener() is called. I am not sure the problems are related. I tryed to figure out from the buglog what is happing but the is way too much info in the buglog 1500 pages. Does anyone have any idea what is causing this bug log?
