   ExecutorService executor = Executors.newSingleThreadExecutor();
   Future future = executor.submit(new Callable() {
       @Override
       public Bitmap call() throws Exception {
       Bitmap bitmap = decodeAndScaleBitmapFromStream(context, inputUri);// do some time consuming operation
       return null;
            }
       });
       try {
           Bitmap result = future.get(1, TimeUnit.SECONDS);
       } catch (TimeoutException e){
           future.cancel(true);
       }
       executor.shutdown();
       return (bitmap!= null);
