Android. Method getduration() of MediaPlayer returns wrong value

I have the following issue with getduration() method of android MediaPlayer. For example with the following file(the real duration of the file is 5747000 ms) :

File to test it

After MediaPlayer is prepared, I'm printing in log cat current position and getduration value in the following code : 

Log.d("Podcast", "getDuration:"+mediaPlayer.getDuration());
Log.d("Podcast","getCurrentPosition:"+mediaPlayer.getCurrentPosition());

In log cat I can see the following :

D/Podcast﹕ getDuration:2885642
D/Podcast﹕ getCurrentPosition:3288059

I found another post with information about that but I have not found a solution. Similar issue found on stackoverflow

How is it possible? Can anyone help me on this?

Thanks. Regards.

You have to convert it into miliseconds..

 public String milliSecondsToTimer(long milliseconds) {
        String finalTimerString = "";
        String secondsString = "";
        String mp3Minutes = "";
        // Convert total duration into time

        int minutes = (int) (milliseconds % (1000 * 60 * 60)) / (1000 * 60);
        int seconds = (int) ((milliseconds % (1000 * 60 * 60)) % (1000 * 60) / 1000);

        // Prepending 0 to seconds if it is one digit
        if (seconds < 10) {
            secondsString = "0" + seconds;
        } else {
            secondsString = "" + seconds;
        }
// menor que 10
        if (minutes < 10) {
            mp3Minutes = "0" + minutes;
        } else {
            mp3Minutes = "" + minutes;
        }
        finalTimerString = finalTimerString + mp3Minutes + ":" + secondsString;
        // return timer string
        return finalTimerString;
    }

Then,

 private Runnable mUpdateTimeTask = new Runnable() {
        public void run() {
            if (mediaPlayer != null && isPlaying) {
                long totalDuration = mediaPlayer.getDuration();
                long currentDuration = mediaPlayer.getCurrentPosition();
                musicSongDurationStart.setText("" + utils.milliSecondsToTimer(currentDuration) + "/" + utils.milliSecondsToTimer(totalDuration));
            }
            if (!isPause) {
                musicSongDurationStart.postDelayed(mUpdateTimeTask, 100);
            }

            // Running this thread after 100 milliseconds
        }
    };

I hope it will help you.

According to this thread: https://code.google.com/p/android/issues/detail?id=2559 The mp3 file should be on 44,100 Hz. Otherwise, the MediaPlayer will scale the time by the ratio of the MP3's actual sample rate to 44,100 Hz.
