      Description

      Responsible for Catroid's extremely high ANR rate of 3.03%, six times higher than Google Play's bad behavior threshold of 0.47% (in comparison, Paintroid's ANR rate is below the threshold after we concentrated on fixing most of the ANR issues; currently it is on average 0.16% for Paintroid):

      Occurs on all Android devices and Android versions.
