java.lang.NullPointerException

I couldn’t reproduce this on my phone and emulators but this affects my users on google play. Sending stacktrace from gplay console:

Android 8.0 (SDK 26)

@jelenalecic & @lecicdjuro,

I guess these lines causes null pointer exception but I don't have any prior experience with Kotlin. https://github.com/CarnegieTechnologies/gallery_saver/blob/master/android/src/main/kotlin/carnegietechnologies/gallery_saver/GallerySaver.kt#L78-L86

Any guesses why I see this crash?

I am facing the same issue here, I guess the problem is that on some phones, callback with native code happens to be null. Changing "!!" to ? will solve the problem but there will be no feedback to indicate whether the operation succeeded or not.

Same problem, with the same stacktrace and the app crashes.

+1 consider #206, this library is discontinued, right?

[enderkoca]
