please note:
Android 5.X and below is not supported for Android Studio version of glbasic. The app can run, but you can run into issues. Etc PNG, JPG and SOUND is not working for those platforms. This is property due change of a newer compiler. Im have not seen issues with Android 6 throught, but if you see glbasic bugs in those Android versions, submit them :-).
API 23 is required.
