Android - Scandit - java.lang.UnsatisfiedLinkError

Question

Scandit SDK started crashing when initializing. It was working fine, but it just started erroring out. I have tried googling around for a solution, and I've tried every suggestion. But nothing seems to fix it. It doesn't seem to be a proguard issue and the build path seems correct.

Help is much appreciated

Answer 1

After talking with a Scandit engineer, it turns the problem was that I didn't have a directory named "armeabi-v7a" in addition to "armeabi". So the libscandit-sdk-android-3.5.3.so file must be present in both subfolders.

Hope this helps someone
