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 button to open a dialog to ask you how you want to open a file (like to choose a file explorer) and then the user will select an mp3 file (it should be possible to enter both internal memory and external, at least those available to users, like in my Xperia V which has 2 internal partitions, and an SD Card), and when a music file is selected (.wav, .mp3, .acc files) to load its name and file path in my app. How can I do it? I am not providing any code, because that's all I need

Answer 1

I use the following to select an mp3 file :

Intent intent;
intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("audio/mpeg");
startActivityForResult(Intent.createChooser(intent, getString(R.string.select_audio_file_title)), REQ_CODE_PICK_SOUNDFILE);

and then you can get the Uri back in onActivityResult :

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQ_CODE_PICK_SOUNDFILE && resultCode == Activity.RESULT_OK){
        if ((data != null) && (data.getData() != null)){
            Uri audioFileUri = data.getData();
            // Now you can use that Uri to get the file path, or upload it, ...
            }
        }
}

I believe selecting other types of audio files would be a matter of setting a wild card in the MIME type by doing intent.setType("audio/*) although I haven't tested that.

Please let me know if that works for you ;-)

Answer 2

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,

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

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

Slight Correction to 2Dee's answer:

    Intent audiofile_chooser_intent;
    audiofile_chooser_intent = new Intent();
    audiofile_chooser_intent.setAction(Intent.ACTION_GET_CONTENT);
    audiofile_chooser_intent.setType("audio/*");
    ActivityOptions options = ActivityOptions.makeScaleUpAnimation(view, 0,
            0, view.getWidth(), view.getHeight());
    startActivityForResult(Intent.createChooser(audiofile_chooser_intent, getString(R.string.select_audio_file_title)), RQS_OPEN_AUDIO_MP3, options.toBundle());

    Toast("File Chooser initiated..");

Intent inside of OnClick listener method to start FileChooser Activity/Dialog

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == RQS_OPEN_AUDIO_MP3) {
            Uri audioFileUri = data.getData();

            String MP3Path = audioFileUri.getPath();
            Toast(MP3Path);


        }
    }
}

OnActivityResult method for obtaining the FilePath of selected file for subsequent use
