Doesn't work if i choose second image after the first image has been cropped

See original GitHub issue

I am using the activity flow of cropping an image. I start the cropper activity by using


and gets the cropped image which i then passes on to another which renders it perfectly. but when i get back to the previous activity which is responsible for using the image, i again starts the cropper activity using the above code. The cropper activity launches but it shows a blank screen with a loader in the center which keeps on loading for like infinity. capture _2016-10-26-17-56-58

In my case, I didn’t use AsyncTask by myself, I used facebook ad sdk to show an ad in previous page of cropper, the loading of the ad was slow, and it blocked the cropper’s loading, so I guess it used AsyncTask too, I can’t control it.

I suggest you can call AsyncTask’s executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR) which can simply execute tasks in parallel.

This is because BitmapLoadingWorkerTask is extend AsyncTask, and every instance of AsyncTask is using the same serial executor by default. When our app use AsyncTask first in other place, then open crop page, BitmapLoadingWorkerTask has to wait to execute until other instance of AsyncTask’s execution finished. I think the author should execute BitmapLoadingWorkerTask on a custom non-serial executor.
