My game on android device shutting down, why?

I just can see s start screen, then the game shutting down. I have already tried it on two devices. I have setup drivers and SDK, JDK, turn on USB Debagging, in game i just set standart controllers for android game.

If you have Unity Pro you can use the Profiler to check for memory leaks. If you just have Unity Free you can use the basic Stats window (atop the gameplay window in the editor) to see how much VRAM you are using, not as helpful but still provides a little insight.

Use adb logcat to get the crash report from your device.
