regards your inquiry, there are several factors could be the reason behind the crash, including but not limited to:
* testing the device with API less than 19 "Android 4.4 KitKat"
* testing on a device that's not an emulator
* testing on a real device with Android Developer options not enabled
* using the "debug" version of the project, rather than the "release" version on a real device.
I'd assume that you're using the debug version since it's the only .apk file that exists in the downloaded folder.
to solve this you should do the following to your Android device:
1- Make sure that the device is running the minimum SDK version or greater, API >= 19
2- Open the device settings, tab the About Phone options, then tab the build number 7 times.
