stack overflow exception in thread on Android

I am doing code for calculating bpm for media files. my requirement is i have to play song only for 5 seconds not more than 5 seconds. so i use Thread.sleep(5000) and i call handler message. it throws java.long.stackoverflowexception.

my code:

currentThread.start(); 
....    
    public void run() {
        try {
            Log.e("bpm", "in run method");
            BPM2SampleProcessor processor = new BPM2SampleProcessor();
            processor.setSampleSize(1024);
            EnergyOutputAudioDevice output = new EnergyOutputAudioDevice(processor);     
            output.setAverageLength(1024);      
            try {
                player = new Player(new FileInputStream("/sdcard/taxi.mp3"), output); // line no 40
                currentThread.run();  // line no 41
                player.play();
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (JavaLayerException e) {
                e.printStackTrace();
            }
           text.setText("bpm is  "+processor.getBPM());
           Log.e("bpm","  bpm is  "+processor.getBPM());            
           Thread.sleep(5000);
       threadHandler.sendEmptyMessage(0);
                         Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }       
    }

private Handler threadHandler = new Handler() 
{
    public void handleMessage(android.os.Message msg) 
    {
     Log.e("calledThread","5seconds");  
     player.close();
    }
};  

log cat:

Your thread calling the run method over and over again, causing a stackoverflow:

currentThread.run();

There is no condition to stop that. (Just to make it clear, currentThread.start() calls the run method in some stage)

You almost answered yourself:

currentThread.run();  // line no 41

Below I wrote example how to deal with your problem:

    AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {
            //put your code here
        }
    };

    try {
        task.execute((Void)null).get(5, TimeUnit.SECONDS);
    } catch(Exception e) {
        e.printStackTrace();
    }
