I have a list view. While clicking the listview an intent is called.. But when i repeatedly perform OnListItemClick, a StackOverflowError is thrown

My code is :

protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);

    Cursor cursor = (Cursor) lAdapter.getItem(position);
    final String lpn = cursor.getString(cursor
        .getColumnIndex(SQLHelper.EMPLOYEE_LPN));
    System.out.println("EMPLOYEE_LPN :   " + lpn);
    final Context con = this;

    final ProgressDialog empDialog = ProgressDialog.show(this, "", "Loading Employee Details ....");
    empDialog.setIcon(R.drawable.icon64);
    empDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    empDialog.show();

    Thread mBackground = new Thread() {

        @Override
        public void run() {


        try{
         // preparing a looper on current thread  the current thread is being detected implicitly     
                Looper.prepare(); 
                DirectoryApp appState = (DirectoryApp) getApplicationContext();
            Object[][] requestArray = new Object[][] {{"lpn",lpn}};
            SOAPHelper soapHelper = new SOAPHelper();
            String result = soapHelper.getHttpTransportResponse(
                appState.getNAMESPACE_DIRECTORY(), "",
                appState.getMETHOD_NAME_GET_EMPLOYEE_DETAILS(), appState.getURL_EYDIRECTORY_SERVICE(), requestArray);

            if(result.equals("")){
                Toast.makeText(ListContacts.this, getString(R.string.connErr),
                    Toast.LENGTH_LONG).show();
            }
            else{
                    Intent intentEmp = new Intent(con,
                    EmployeeDetails.class);
                intentEmp.putExtra("result",
                    result);
                startActivity(intentEmp);

            }
            empDialog.dismiss();
            handler.sendEmptyMessage(1);

        }
        catch (Exception e) {
            empDialog.dismiss();
            Bundle bundle = new Bundle();
            bundle.putInt("flag", 0);
            Message message = new Message();
            message.setData(bundle);
            handler.sendMessage(message);
        }

        }

    };

    // start the background thread
    mBackground.start();
    Looper.loop();


    }


    private Handler handler = new Handler() {

    @Override
    public void handleMessage(Message msg) {

        super.handleMessage(msg);

        int flag = msg.getData().getInt("flag");
        switch (flag) {
        case 0:
            Toast.makeText(ListContacts.this, getString(R.string.connErr),
                Toast.LENGTH_LONG).show();
            break;
        case 1:
            break;
        default:
            Toast.makeText(ListContacts.this, getString(R.string.connErr),
                Toast.LENGTH_LONG).show();
        }

    }
};

And the exception is :

I have got the answer :

@Override
public void run() { 
try { 
// preparing a looper on current thread 
// the current thread is being detected implicitly 
Looper.prepare(); 
// now, the handler will automatically bind to the 
// Looper that is attached to the current thread 
// You don't need to specify the Looper explicitly 
handler = new Handler(); 
// After the following line the thread will start 
// running the message loop and will not normally 
// exit the loop unless a problem happens or you 
// quit() the looper (see below) 
Looper.loop(); 
} catch (Throwable t) { 
Log.e(TAG, "halted due to an error", t); 
} 
}
