This works for me   seekbarPlayer setMax mp getDuration     getActivity   runOnUiThread new Runnable           Override     public void run             if mp    null               seekbarPlayer setProgress mp getCurrentPosition                       mHandler postDelayed this  1000

To add on to  hardartcore s answer     Instead of calling postDelayed on a Handler  the best approach would be to get callbacks from the MediaPlayer during play-back and then accordingly update the seekBar with the progress  Also  pause your MediaPlayer at onStartTrackingTouch SeekBar seekBar  of the OnSeekBarChangeListener and then re-start it on onStopTrackingTouch SeekBar seekBar

int  pos    0      yourSeekBar setMax mPlayer getDuration       After You start Your MediaPlayer i e mplayer start    Try this code  while mPlayer  null            try                   Thread sleep 1000                   pos    mPlayer getCurrentPosition                   catch  Exception e                      show exception in LogCat                           yourSeekBar setProgress pos           Before you added this code you have to create xml resource for SeekBar and use it in Your Activity class of ur onCreate   method

To create a  connection  between SeekBar and MediaPlayer you need first to get your current recording max duration and set it to your seek bar   mSeekBar setMax mFileDuration 1000      where mFileDuration is mMediaPlayer getDuration      After you initialise your MediaPlayer and for example press play button  you should create handler and post runnable so you can update your SeekBar  in the UI thread itself  with the current position of your MediaPlayer like this    private Handler mHandler   new Handler      Make sure you update Seekbar on UI thread MainActivity this runOnUiThread new Runnable           Override     public void run             if mMediaPlayer    null               int mCurrentPosition   mMediaPlayer getCurrentPosition     1000              mSeekBar setProgress mCurrentPosition                     mHandler postDelayed this  1000               and update that value every second    If you need to update the MediaPlayer s position while user drag your SeekBar you should add OnSeekBarChangeListener to your SeekBar and do it there            mSeekBar setOnSeekBarChangeListener new SeekBar OnSeekBarChangeListener               Override         public void onStopTrackingTouch SeekBar seekBar                         Override         public void onStartTrackingTouch SeekBar seekBar                             Override             public void onProgressChanged SeekBar seekBar  int progress  boolean fromUser                                    if mMediaPlayer    null  amp  amp  fromUser                       mMediaPlayer seekTo progress   1000                                             And that should do the trick       EDIT  One thing which I ve noticed in your code  don t do    public MainActivity         mFileName   Environment getExternalStorageDirectory   getAbsolutePath        mFileName      audiorecordtest 3gp       make all initialisations in your onCreate      do not create constructors of your Activity

Given the answer hardartcore that worked for me with a small change and did not work before the change   private Handler mHandler   new Handler    MusicPlayer this runOnUiThread new Runnable           Override      public void run               if player    null                  int mCurrentPosition   player getCurrentPosition     clear    1000                  seekBar setProgress mCurrentPosition                         mHandler postDelayed this  1000                  seekBar setOnSeekBarChangeListener new SeekBar OnSeekBarChangeListener           Override     public void onStopTrackingTouch SeekBar seekBar                 Override     public void onStartTrackingTouch SeekBar seekBar                 Override     public void onProgressChanged SeekBar seekBar  int progress  boolean fromUser              if player    null  amp  amp  fromUser                 player seekTo progress      clear     1000

User · Answer

check this  you should give arguments in msecs  Dont just send progress to seekTo int   and also check this getCurrentPostion   and getDuration     You can do some calcuations  ie   convert progress in msec like msce    progress 100  getDuration   then do seekTo msec   Or else i have an easy idea  you don t need to change any code anywer else just add seekBar setMax mPlayer getDuration    once your media player is prepared   and here is link exactly what you want seek bar update

Based on previous statements  for better performance  you can also add an if condition  if  player isPlaying         handler postDelayed      1000

After you initialize your MediaPlayer and SeekBar  you can do this     Timer timer   new Timer        timer scheduleAtFixedRate new TimerTask              Override         public void run                 mSeekBar setProgress mMediaPlayer getCurrentPosition                     0 1000     This updates SeekBar every second 1000ms   And for updating MediaPlayer  if user drag SeekBar  you must add OnSeekBarChangeListener to your SeekBar    mSeekBar setOnSeekBarChangeListener new SeekBar OnSeekBarChangeListener              Override         public void onProgressChanged SeekBar seekBar  int i  boolean b                mMediaPlayer seekTo i                       Override         public void onStartTrackingTouch SeekBar seekBar                         Override         public void onStopTrackingTouch SeekBar seekBar                         HAPPY CODING
