When I import my own .jar library after importing Scichart .aar libraries(core and data) my own .jar library generates an error(Error: findLibrary returned null). How can I overcome that error.

Hi Hamza Kiani,

Unfortunately I’m not aware about such problem ( at least there was no such errors with other third-party libraries which our customers use in their applications ). So I want to ask you to create a project which reproduces this issue and we’ll try to find and fix the cause of this error.

Best regards,
Yura

    I am using .so files in my project it works fine, but when i import Scichart libraries in my project it generates an error while loading .so files from jniLibs folder (java.lang.UnsatisfiedLinkError: Couldn’t load Health7500-1.0.5 from loader dalvik.system.PathClassLoader[DexPathList[[zip file “/data/app/com.example.healthintegratedmachine-1.apk”],nativeLibraryDirectories=[/data/app-lib/com.example.healthintegratedmachine-1, /vendor/lib, /system/lib]]]: findLibrary returned null)

    My .so file is only conflicting with ‘core’ and ‘data’ libraries of scichart. Whenever I import core and data library in my application .so file generates an error (find Library returned null ) but when I comment both lines ‘core’ and ‘data’ it works fine,other libraries of Scichart ‘drawing’ ‘,’charting’ and ‘extensions’ works fine every time.

    So you use NDK in your project, right? You didn’t mention this before and I thought that you used some Java library. That’s why I asked about project which reproduces this issue and if you don’t provide it I won’t be able to help you with this issue.

Hi Hamza Kiani,

Thanks, I took a look on your application and it looks like that you placed your .so file into jniLibs/armeabi folder which according to documentation was deprecated and can’t be used anymore. Not sure why your project works if comment include of SciChart library ( maybe there are some fallbacks if there no other abi’s for APK), but to fix this issue you just need to create jniLibs/armeabi-v7a or jniLibs/arm64-v8a folder ( it depends on CPU architecture of device which you use for testing or you can create both) and place your libHealth7500-1.0.5.so there. Then recompile project. This steps fixed your project for me.

Hope this will help you!

Best regards,
Yura
