}

you can not access computer disk drive android.

just keep b.wma in assets folder .

then use following code use b.wma

 try {     inputstream  = context.getassets().open(url);     } catch (ioexception e) {     // todo auto-generated catch block     e.printstacktrace();       } 

hope helps you.
