a black screen appears and exit when running games android

Hi… I’m using Unity v5.3.1p1. Why when I run Games in Android that have built in Unity only a black screen appears and exit ? But at the time of building the Games in Unity there is no error and run smoothly.

why this is happening?

Thanks

It crashes. Debug your game on your device using logcat and paste the logcat error log here if you can’t make sense of it.
