Android select mp3 file

Question

Sorry if this has already been answered, but I can\'t specify my question very well. I have an activity that needs a song file from your device, and I want it when I press a

Answer 1

To open file explorer, requestCode is just an integer so for sake , pass 1

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("audio/*"); // specify "audio/mp3" to filter only mp3 files
startActivityForResult(intent,1);

Setup Media Player,

MediaPlayer player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);

Fetch result file from explorer,

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

 /*check whether you're working on correct request using requestCode , In this case 1*/

    if(requestCode == 1 && resultCode == Activity.RESULT_OK){
        audio = data.getData(); //declared above Uri audio;
        Log.d("media", "onActivityResult: "+audio);
    }

    super.onActivityResult(requestCode, resultCode, data);
}

Start Playing audio,

 player.setDataSource(new FileInputStream(new File(audio.getPath())).getFD());

 player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mediaPlayer) {
                    player.start();
                }
            });

 player.prepareAsync();

To stop audio,

 if(player.isPlaying())
            player.stop();

Finally, Add permission in manifest to read external files,

Add your controller widgets and play with MediaPlayer methods to create customized Mp3 player ;)
