If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

Please attach any image files, URL and stack trace that can be used to reproduce the bug.

Which versions of uCrop, and which Android API versions are affected by this issue? Did this work in previous versions of uCrop?

Hello @happysmile123, thanks for the issue.
I've just fixed this bug, it was related to ExifInterface and PNG files cannot live together.
Should be available in the next library build soon.

Please check the latest uCrop version
Now you can choose between:

Lightweight general solution

compile 'com.yalantis:ucrop:2.2.0' 

Get power of the native code to preserve image quality (+ about 1.5 MB to an apk size)

compile 'com.yalantis:ucrop:2.2.0-native'
