Hi,

Thanks for reporting this. I'm not sure if this is a device issue or Android issue. From the logs I can read that it's running Android 4.1. Maybe backward-compatibility doesn't work well...
I'm also wondering why do you have jacoco in the logs as it should be executed during measuring test coverage only.
