  • Try changing mp3.setDataSource("sdcard/musicblee/Over_the_horizon.mp3"); to mp3.setDataSource("/mnt/sdcard/musicblee/Over_the_horizon.mp3"); – Akshay Jul 05 '17 at 06:45
  • Also I would suggest you to move the entire try catch block in the onclicklistenr of the start button – Akshay Jul 05 '17 at 06:48

refer to this link use mp3.setDataSource() like that

mp3 = MediaPlayer.create(this,Uri.parse(Environment.getExternalStorageDirectory().getPath()+ "/musicblee/Over_the_horizon.mp3"));

to set mp3 source. And Also add this permission to your Android Manifest file : 

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
