                if(ringTone!=null){
                    //previous ringTone is playing,
                    //stop it first
                    ringTone.stop();
                }

                        .getRingtone(getApplicationContext(), uriRingtone);
                }

                Toast.makeText(MainActivity.this,
                    ringTone.getTitle(MainActivity.this),
