Mediaplayer progress update to seekbar not smooth?

Question

I am working on an app with recorder and player. I am using mediaplayer to play the recorded .wav file and meantime I want to update to a seekbar. Everything is working fine But

Answer 1

seekbar.setProgress() only accepts int. Hence, most of us tend to pass the elapsed percentage to this method. However, if you need much smoother progression, then you can use the duration in milliseconds as the MAX. Then we get to update the progression of the seekbar every millisecond. Below is an example and I have updated it every 15th millisecond as almost every android phone comes with a refresh rate of 60 fps (frames per second).

    try{
        mediaPlayer.start();
        seekbar.setProgress(0);
        seekbar.setMax(mediaPlayer.getDuration());

        // Updating progress bar
        seekHandler.postDelayed(updateSeekBar, 15);
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    }

/**
 * Background Runnable thread
 * */
private Runnable updateSeekBar = new Runnable() {
    public void run() {
        long totalDuration = mediaPlayer.getDuration();
        long currentDuration = mediaPlayer.getCurrentPosition();

        // Displaying Total Duration time
        remaining.setText(""+ milliSecondsToTimer(totalDuration-currentDuration));
        // Displaying time completed playing
        elapsed.setText(""+ milliSecondsToTimer(currentDuration));

        // Updating progress bar
        seekbar.setProgress((int)currentDuration);

        // Call this thread again after 15 milliseconds => ~ 1000/60fps
        seekHandler.postDelayed(this, 15);
    }
};

/**
 * Function to convert milliseconds time to
 * Timer Format
 * Hours:Minutes:Seconds
 * */
public String milliSecondsToTimer(long milliseconds){
    String finalTimerString = "";
    String secondsString = "";

    // Convert total duration into time
    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);
    // Add hours if there
    if(hours > 0){
        finalTimerString = hours + ":";
    }

    // Prepending 0 to seconds if it is one digit
    if(seconds < 10) {
        secondsString = "0" + seconds;
    }else {
        secondsString = "" + seconds;
    }

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

    // return timer string
    return finalTimerString;
}
