get duration of audio file

Question

I have made a voice recorder app, and I want to show the duration of the recordings in a listview. I save the recordings like this:

MediaRecorder recorder =          


        

Answer 1

It's simply. use RandomAccessFile Below is the code snippet to do so

 public static int getAudioInfo(File file) {
    try {
        byte header[] = new byte[12];
        RandomAccessFile randomAccessFile = new RandomAccessFile(file, "r");
        randomAccessFile.readFully(header, 0, 8);
        randomAccessFile.close();
        return (int) file.length() /1000;
    } catch (Exception e) {
        return 0;
    }
}

You can, of course, be more complete depending on your needs
