+### Android get jni
+How to compile is in [example](https://github.com/gen2brain/raylib-go/blob/master/examples/others/android/example/README.md), this example:
+- show how get jni enviroment 
+- add build.sh which you need only rewrite paths and run
+- show what you need to add to your project to see fmt output in logcat in init_android.go
