Android SDK MediaPlayer doesn't seek correctly

Question

I have a mp3 file and my application must seek to some selected time of that mp3 file then start playing from there.

I convert my string time by this method to int value

private static int convert(String time) {
    int quoteInd = time.indexOf(":");
    int pointInd = time.indexOf(".");

    int min = Integer.valueOf(time.substring(0, quoteInd));
    int sec = Integer.valueOf(time.substring(++quoteInd, pointInd));
    int mil = Integer.valueOf(time.substring(++pointInd, time.length()));

    return (((min * 60) + sec) * 1000) + mil;
} 

Note: my stings is like this 5:12.201 that means 5 mins and 12 seconds and 201 milliseconds.

I getted these times from MP3 Audio Editor application (it's for windows) and I checked theme with KMPlayer application (it's for windows). And these times was correct on both of them.

But in my app when I seek my MediaPlayer to that time, audio doesn't start from my selected position. (time is correct but sound is different.)

---

I thought that the MediaPlayer doesn't seek to that time correctly. So I checked current position by calling getCurrentPosition() before playing but returned value and seeked value was same.

I haven't any Idea about It.

Edit:

My problem is NOT time converting.

I convert and seek to there correctly but it play something that not expected in that time.

It means timing in KMPlayer and Android are differents.

My question is Way? and How can is solve it?

Answer 1

You must seek using the seekTo method. This expects miliseconds as time offset. Your offset is how far from the beginning you want to play, for example 1 minute from start can be your offset.

Note: my strings is like this 5:12.201 (Mins : Secs : Millisecs)

If you want to seek to a time like 5:12.201 then use seekTo(312201);

Explained :

1000 ms gives you one second, so 12000 is 12 seconds, and 60000 is one minute.

If you want 5m:12s time then do as :

MyMins = 1000 * 60 * 5; //# 5 mins at 60 secs per minute
MySecs = 1000 * 12; //# 12 secs
MyMilliSecs = 201; //# 201 millisecs
SeekValue = (MyMins + MySecs + MyMilliSecs);
seekTo(SeekValue); //# seeks to 312201 millisecs (is == 5 min & 12 secs & 201 ms)

Answer 2

I usually use this function.

I think It can help to you.

 public static String milliSecondsToTimer(long milliseconds){
    String finalTimerString = "";
    String secondsString = "";

    int hours = (int)( milliseconds / (1000*60*60));
    int minutes = (int)(milliseconds % (1000*60*60)) / (1000*60);
    int seconds = (int) ((milliseconds % (1000*60*60)) % (1000*60) / 1000);
    if(hours > 0){
        finalTimerString = hours + ":";
    }

    if(seconds < 10){
        secondsString = "0" + seconds;
    }else{
        secondsString = "" + seconds;}

    finalTimerString = finalTimerString + minutes + ":" + secondsString;

    return finalTimerString;
}

Good luck :)
