Attempt to read from field 'int android.graphics.Bitmap$Config.nextInt' on a null object reference

First, I select a gif photo from gallery, then to crop the photo with a full size , it will report this problem below :
Attempt to read from field 'int android.graphics.Bitmap$Config.nextInt' on a null object reference.

if the size you croped is not full size, it's woked well.

Reproduce the issue by selecting a GIF from the gallery and cropping it at full size, then compare that with a smaller crop that works. Trace the Android image-cropping flow involved in both cases; done means full-size GIF cropping completes without the reported null-object exception.
