Do you guys have adb logcat output for the game starting time, logged from the mobile phone? That would be interesting. Without that log one can’t say a thing. Maybe the demo uses some GL command that is not available on the platform, or a shader with to extensive ressource usage or something. - If you know where the error is, you might be able to avoid it, e.g. by using a different or less complex shader.
Another wuestion would be: Does an almost empty project with only the simplest shader usage run on the phone? - If not it won’t work for the more complex context also.
