How can I pass a Bitmap object from one activity to another

Question

In my activity, I create a Bitmap object and then I need to launch another Activity, How can I pass this Bitmap object from the sub-ac

Answer 1

Because Intent has size limit . I use public static object to do pass bitmap from service to broadcast ....

public class ImageBox {
    public static Queue mQ = new LinkedBlockingQueue(); 
}

pass in my service

private void downloadFile(final String url){
        mExecutorService.submit(new Runnable() {
            @Override
            public void run() {
                Bitmap b = BitmapFromURL.getBitmapFromURL(url);
                synchronized (this){
                    TaskCount--;
                }
                Intent i = new Intent(ACTION_ON_GET_IMAGE);
                ImageBox.mQ.offer(b);
                sendBroadcast(i);
                if(TaskCount<=0)stopSelf();
            }
        });
    }

My BroadcastReceiver

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
        public void onReceive(Context context, Intent intent) {
            LOG.d(TAG, "BroadcastReceiver get broadcast");

            String action = intent.getAction();
            if (DownLoadImageService.ACTION_ON_GET_IMAGE.equals(action)) {
                Bitmap b = ImageBox.mQ.poll();
                if(b==null)return;
                if(mListener!=null)mListener.OnGetImage(b);
            }
        }
    };
