How to stream mp3 url using exoplayer?

Question

Exoplayer library seems so complex for me. Can anyone help me how to stream radio station url using exoplayer library? I tried with MediaPlayer , it works fine but it took so much time to prepare. Here is what I tried.

    exoPlayer = ExoPlayer.Factory.newInstance(RENDERER_COUNT);

    Allocator allocator = new DefaultAllocator(BUFFER_SEGMENT_SIZE);
    DataSource dataSource = new DefaultUriDataSource(getApplicationContext(), null, userAgent);
    Mp3Extractor extractor = new Mp3Extractor();
    ExtractorSampleSource sampleSource = new ExtractorSampleSource(
            uri, dataSource, extractor, allocator, BUFFER_SEGMENT_COUNT * BUFFER_SEGMENT_SIZE);
     MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource);
    exoPlayer.prepare(audioRenderer);

    exoPlayer.setPlayWhenReady(true);

I don't understand how to get userAgent and what is meaning of it?

Answer 1

Here is a nice description of what a user agent is: user agent Also here the definition of how a user agent should look like: structure of user agent header Here you can see how your browser's user agent looks like: http://whatsmyuseragent.com/

To put it simply you can create your user agent like this:

"YourAppName/VersionCode"

Finally a description of how to use ExoPlayer to stream mp3: Stream mp3 with ExoPlayer In this example it is a local mp3 though, but the only difference should be the url of the mp3 and the missing user agent. Hope this helps!
