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

Wed Nov 26 16:54:38 UTC 2014

It should be
<AndroidNativeLibrary Include="Resources\lib\armeabi-v7a\libcyusb.so" />,
that is what Jonathan meant by choosing the action (you can change it on
the properties window when selecting the item in the solution explorer),
also it is not a good thing to put it inside the Resources folder, it is
not an embeddable resource, it will be packed in the apk not in the managed
dll.
