Android : android mediaplayer song play skip and jumping

I have build an android application, in a particular module i have used media player class to play songs. Sometimes the songs get skipping and jumping a bit when we play the songs via application. Can anyone please assist us with this, thanks. seekbar.setOnSeekBarChangeListener(new seekchange()); public class seekchange implements SeekBar.OnSeekBarChangeListener { public void onStopTrackingTouch(SeekBar arg0) { // TODO Auto-generated method stub }

       public void onStartTrackingTouch(SeekBar arg0)
       {
           // TODO Auto-generated method stub

       }
       public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) 
       {
           // TODO Auto-generated method stub
           if (fromUser)
           {
               mp.seekTo(progress);
               seekBar.setProgress(progress);
           }
       }
   }
   //seekbar song listenet
   public class setp implements MediaPlayer.OnPreparedListener  
   {
      public void onPrepared(MediaPlayer mps) 
      {
          // TODO Auto-generated method stub
          seekbar.setMax(mp.getDuration());
          System.out.println("Total Duration Mp3" + mp.getCurrentPosition());

          new Thread(new Runnable() 
          {
            public void run() 
            {
                try
                {
                    while(mp!=null && mp.getCurrentPosition()<mp.getDuration())
                    {
                        seekbar.setProgress(mp.getCurrentPosition());
                        Message msg=new Message();
                        int millis = mp.getCurrentPosition();

                        msg.obj=millis/1000;

                     try 
                     {
                             Thread.sleep(100);
                     } 
                     catch (InterruptedException ie) 
                     {
                         System.out.println("InterruptedException SeekBar" + ie);
                     } 
                     catch (IllegalMonitorStateException imse) 
                     {
                         System.out.println("IllegalMonitorStateException SeekBar" + imse);
                     }
                     catch (IllegalStateException ise)
                     {
                         System.out.println("IllegalStateException SeekBar" + ise);
                     }
                     catch (Exception e) 
                     {
                         System.out.println(" Exception SeekBar" + e);
                     }

                 }
             } catch (IllegalStateException e)
             {

                 System.out.println("seekbar out IllegalStateException" + e);
             } 
                catch (IllegalMonitorStateException e) 
             {
                 System.out.println("seekbar out IllegalMonitorStateException" + e);
             }
                catch (Exception e) {
