i seem to be having a very strange problem, when the app is run on my test phone it works perfectly, and plays a sound from the raw folder via soundpool on button press, however when i submit my app to testing after building it it crashes on 120+ devices for 'Resource not found'

codes below: Please also note, the file is in fact there, in both the R file, in the compiled APK file and i have also cleaned numerous times.
