To reproduce:
1) Open attached project (ReadyToBuild one)
2) Build and run on device (everything is already set in the project)
3) It will start loading, and crash

DUT: Motorola Moto G (Android 5.1) (Reproduced 100% in all versions)
Google Nexus 5 (Android 6.0.1) (Reproduced randomly. Sometimes it fails multiple times in row, sometimes it succeeds. Doesn't seem to be any recognizable pattern apart from note below. Cannot reproduce in 5.3.2p3)
HTC One M9+ (Android 6.0) (Reproduced like Nexus 5)
Samsung Galaxy S6 edge (Android 5.1.1) (Reproduced like Nexus 5)
Sony Xperia Z (Android 5.0.2) (Reproduced like Nexus 5)
Samsung Galaxy Tab 4 10.1 WiFi (Android 5.0.2) (Reproduced like Nexus 5)

Note: The crashes seem to be more consistent if the app is deleted and reinstalled. The more the app stays in device, the more random it gets, same if app is rebuilt/reinstalled without deleting the old one
