When apps that uses libretroshare are compied and proguard is run, Java
classes coming from libretroshare and that are used only by
libretroshare C++ code were errouneously stripped by proguard.
Bundle proper proguard rules in the AAR to avoid runtime errors such
as
java.lang.ClassNotFoundException: Didn't find class "org.retroshare.service.AssetHelper" on path: DexPathList[[zip file "/data/app/com.example.retroshare_aar
