java.io.IOException: Native library (android-arm/libwirehair.so) not found in resource path

Hi,
I tried to include your RUDP library but I can not manage to make it run.
It builds without any problems, however as soon as I want to open a socket I get the following
error:
java.lang.ExceptionInInitializerError

Prior to that error, I received:
java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/android-arm/libjnidispatch.so) not found in resource path (.)
I managed to fix that according to the solution of
https://stackoverflow.com/questions/47800043/android-arm-libjnidispatch-so-not-found-error
However, I have no Idea on how to fix that problem with the libwirehair.so
I'd realy like to use your implementation because of its simplicity and elegancy, but first I have to make it run :(

Edit: I am using Android Studio with Kotlin 1.3.41 and gradle 3.4.2

Hey @ImDolfin !
Sorry for such a long delay.

To run this library with Android you first need to compile libwirehair to your ABI.
Roughly speaking you need:

1. download android toolchain
2. build libwirehair from source using this toolchain (google some examples of how this can be done)
3. place resulting libwirehair.so under jniLibs/<your-abi>

After this everything should work properly.

@seniorjoinu Where are the sources to build libwirehair.so? I easily found https://github.com/catid/wirehair, but it's unclear to me if that builds this target. I'm a little unfamiliar with reading cmake files.
