  private void translucentActivity(Activity activity) 

        try 
            activity.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            activity.getWindow().getDecorView().setBackground(null);
            Method activityOptions = Activity.class.getDeclaredMethod("getActivityOptions");
            activityOptions.setAccessible(true);
            Object options = activityOptions.invoke(activity);

            Class<?>[] classes = Activity.class.getDeclaredClasses();
            Class<?> aClass = null;
            for (Class clazz : classes) 
                if (clazz.getSimpleName().contains("TranslucentConversionListener")) 
                    aClass = clazz;
                
            
            Method method = Activity.class.getDeclaredMethod("convertToTranslucent",
                    aClass, ActivityOptions.class);
            method.setAccessible(true);
            method.invoke(activity, null, options);
         catch (Throwable t) 
            t.printStackTrace();
