How to convert a ParseFile into a playable 3GP file

Question

Im working on an app which uploads and downloads audio files from www.parse.com. I upload them as parseFile and it works perfect. When I download the parseFile, how can i convert it to something my android can play it?

Note: I upload the files in format .3gp

You can convert your ParseFile into a Byte[] with the getData() method.

Then, you can play the song from the Byte[] by using this function with some edit (from Android - Playing mp3 from byte[]) :

private void play3GP(byte[] 3gpSoundByteArray) {
    try {
        File temp3GP = File.createTempFile("temp_audio", "3gp", getCacheDir());
        temp3GP.deleteOnExit();
        FileOutputStream fos = new FileOutputStream(temp3GP);
        fos.write(3gpSoundByteArray);
        fos.close();

        MediaPlayer mediaPlayer = new MediaPlayer();

        FileInputStream fis = new FileInputStream(temp3GP);
        mediaPlayer.setDataSource(fis.getFD());

        mediaPlayer.prepare();
        mediaPlayer.start();
    } catch (IOException ex) {
        String s = ex.toString();
        ex.printStackTrace();
    }
}

Thnx a lot! Worked beautifully! – Antonio Aug 27 '14 at 02:17 — Antonio, Aug 27 '14 at 02:17

3GPP is fine as you see in the link. You just have to POST the file with a mime type that indicates what it is. See the curl code using the parse REST Api Posting audio with a 'Content-type' header.

When you do a GET it should come with that mimeType and the media player should be able to handle it with just a URL ref to the parse file.

 --header "Transfer-Encoding: chunked" --header "Content-Type: audio/amr-wb; rate=8000"  --data-binary @yourFile.3gp

so try uploading with those headers then use the URL from the response to load to MediaPlayer.
