I have this problem on android 4.2.2.

I submit a PR with a fix for this issue #279.
While the PR isn't merged, you can do a quick fix by adding this to your Activity or Fragment where the com.wonderkiln.camerakit.CameraView is.

    static {
        System.loadLibrary("jpge");
        System.loadLibrary("jpgd");
        System.loadLibrary("JniYuvOperator");
        System.loadLibrary("JniBitmapOperator");
    }

Thanks for your PR @4brunu , merged into next release branch. Will release today.

[4brunu]

This was fast! thanks 👍

I am testing master (47cda44) and am experiencing the UnsatisfiedLinkError. I also tried to deploy the demo apk directly to the phone, instead of using the Run function of Android Studio (suspecting some Android Studio flaw). Am I doing something wrong?

[4brunu]

@udanieli Could show the stack strace?
Probably this is related with Replace jpgd and jpge with libjpeg-turbo

[udanieli]

Thank you for the quick reply. Stack trace is null. I only see this:
java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1891]: 25444 could not load needed library 'libyuvOperator.so' for 'libjpegTransformer.so' (load_library[1093]: Library 'libyuvOperator.so' not found)

here is something that seems a call stack:

I tried to add --stacktrace --debug parameters to gradle cmdline. Logcat is empty, I have checked No filters option, nothing.
I am a frustrated Android newbie. I have been working for years with Java but never fell in love with it. I still have the clear feeling of not having control over things in the Java ecosystem, especially debugging seems a hard task to accomplish. Please have mercy.

[4brunu]

Can you share a sample project showing the error?

[udanieli]

It's the demo module in library's project, at revision 47cda44 (did not touch any file).

[udanieli]

Looking to the source code and the commit you pointed me (431f59d) it seems that this fix should be done again. Just testing, I made this simple patch:

https://github.com/udanieli/camerakit-android/commit/06e55ac8825cd0e5d181bf5a79dc21e977f618ed

then the demo crashes anyway for an OutOfMemoryException thrown from here, maybe because my camera creates a really big photo. Running the demo on an emulated device (640x480) no exception, the demo runs smoothly. I think it's another story.

[4brunu]

@udanieli Your fix looks good 👍
Yes, thats a separated issue.
Could you please submit a Pull Request with the fix?

Second that, would love a PR, we can look at immediately merging.
