apps crash after splash screen on all devices..

i created a simple testing thing where i have a cube that moves around, following the tutorials I watched.
I have built and ran on my android phone, and i have also copied the .apk onto my phone same thing,
When I run it in Xcode and in the simulator it does the same thing.

Anyone know why it does this, or how i can fix it…?

Thanks,
Dominic

The best thing for you to do is check the logs. For Android on a Mac the best way to do that is through the ADB.

Open up the terminal and write:

./adb logcat

Look for null exceptions. Nasty little things.
