[mak12]

when ever showProgress(); is called i am getting an exception and application is crashing , check for the reason and found it was this line causing the issue

  public void showProgress() {
       try {

           //here is the crash happening 
            windowManager.addView(progressLayout, layoutParams); 

    }
    catch (WindowManager.BadTokenException e){
        Log.d("ProgressWindow" ,"ReasonFor"+e.toString());
    }

}
