Store Application Preference Android

I have added a mute button to a menu on my application and am wondering if it is possible to store the user's latest preference of either muted or unmuted for use when he/she reopens the application.

Here is the code I am using for setting mute or umute:

public void isMute() {

      if(mIsMute){    
          mAm.setStreamMute(AudioManager.STREAM_MUSIC, false);
          mIsMute = false;

      }else{
          mAm.setStreamMute(AudioManager.STREAM_MUSIC, true);
          mIsMute = true;
      }
    }

Use SharedPreferences to store the state. Read it when application starts and set current state.

I modified a little example from android documentation

public class Calc extends Activity {
    public static final String PREFS_NAME = "MyPrefsFile";

    @Override
    protected void onCreate(Bundle state){         
       super.onCreate(state);
       . . .

       // Restore preferences
       SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
       mIsMute = settings.getBoolean("IsMute", false);
       isMute();
    }

    @Override
    protected void onStop(){
       super.onStop();

      // We need an Editor object to make preference changes.
      // All objects are from android.context.Context
      SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
      SharedPreferences.Editor editor = settings.edit();
      editor.putBoolean("IsMute", mIsMute);

      // Commit the edits!
      editor.commit();
    }
}
