how to play audio file from url in android

Question

I need to play audio file from remote server in my app. I could play when I tested with localhost server (using WAMP). When the same file supplied from the server it is not working.. The file has no extension and the content is MP3

String fileUrl = "http://192.168.1.131/myproject/songs/xyz";
String url = "http://myserver/songs/xyz"; //(myserver -> A remote server)
mVideoView.setVideoURI(Uri.parse(fileUrl));
mVideoView.requestFocus();

Also I need to have a better control over player.
Please help...

Solution 1

public void onRadioClick(View v) {

    if (!isPLAYING) {
        isPLAYING = true;
        MediaPlayer mp = new MediaPlayer();
        try {
            mp.setDataSource(getString(R.string.audio_stream));
            mp.prepare();
            mp.start();
        } catch (IOException e) {
            Log.e(LOG_TAG, "prepare() failed");
        }
    } else {
        isPLAYING = false;
        stopPlaying();
    }
}

private void stopPlaying() {
    mp.release();
    mp = null;
}

Solution 2

The answer provided above provides synchronous fetching and playing, meaning currently executing thread will be blocked until prepare() is completed.

prepareAsync() can be used instead to "prepare" the stream asynchronously. You also will need to handle onPrepared() event to start playing.

mediaPlayer.setDataSource(URL here);
mediaPlayer.prepareAsync();

Add OnPrepared event handler:

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

Still, apparently there is no way to configure streaming buffer size. Frustrating...

Solution 4

If you are writing Java programs to play media files, then the first port of call is the MediaPlayer class. Typical code to play a file using the streaming mechanism of MediaPlayer is

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    try {
        Uri uri = Uri.parse("http://192.168.1.9/music/test.ogg");
        MediaPlayer player = new MediaPlayer();
        player.setAudioStreamType(AudioManager.STREAM_MUSIC);
        player.setDataSource(this, uri);
        player.prepare();
        player.start();
    } catch(Exception e) {
        System.out.println(e.toString());
    }
}

Wake Lock Permission - If your player application needs to keep the screen from dimming or the processor from sleeping, or uses the MediaPlayer.setScreenOnWhilePlaying() or MediaPlayer.setWakeMode() methods, you must request this permission.

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

To configure streaming buffer size into custom blocks Google recommends using it's ExoPlayer. It's what the YouTube app uses right now and works for mp3 streaming.

[Sumit Shukla]

If you want to play audio only, then you should go with MediaPlayer because ExoPlayer consumes more battery than MediaPlayer.
