i have function run audio public void playsound(string filename){ mediaplr = mediaplayer.create(context, r.raw.s1); mediaplr.start(); } the problem r.raw.s1 , want replace s1 filename , doesn't take string. can do??? thanks help if file stored in res/raw/ directory, can retrieve identifier through following code: public void playsound(string filename){ int sound_id = context.getresources().getidentifier(filename, "raw", context.getpackagename()); if(sound_id != 0) { mediaplr = mediaplayer.create(context, sound_id); mediaplr.start(); } } i prefer start variable names small letters, rather capital. helps distinguish static class. you can create map store id further reuse instead of retrieving identifier each time.
