mRunnable = new Runnable(){
    @Override
    public void run() {
        if(count == 0){
            // do something
            count = 1;
        }
        else if (count==1){
            // do something
            count = 0;
        }
        m_Handler.postDelayed(mRunnable, 3000);// move this inside the run method
