Unable to load library from file path

Well I have checkout the #58 from @artyomd, but failing to load the native library from dataDirectory.

Any help is appreciated.

[benjamin-bader]

This isn't a relinker error, something is wrong with the JNI initialization in the native library itself. If this is your own code, then you'll need to fix it yourself, otherwise file a bug report with whomever distributed it. We can't help.

[srikanthsunkari]

Sure, This is not my code. It is one of my third-party libraries, I have no clue why this crash happened. But when I am packaging the so files with the APK, I did not observe this crash. It only occurs when I load the libraries from Activity.getDir("libs") path. Is this related to any integration issue ? I looked in both repo's didn't find usage of Relinker.load(context, file) with library file path Can you please provide an example usage of Relinker.load(context, file) method, to cross verify from my end in between.
Thanks.
