[Mono-dev] Using .so file in Android Library Project and then using it in an Android App

Wed Nov 26 16:08:23 UTC 2014

I have created a lib file in the resources folder, and armeabi-v7a folder
in the lib file and put the libcyusb.so there. When I look at the csproj
file, it has changed like that:

<ItemGroup>
    <AndroidEmbeddedJavaLibrary
Include="Resources\lib\armeabi-v7a\libcyusb.so" />

However, I'm still getting " can not load dll" error:
