I'm getting this when the library running on Android attempts to connect:

05-11 16:31:08.623 E/AndroidRuntime(21464): java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.NoClassDefFoundError: Failed resolution of: Ljava/net/http/HttpClient;

I think we could make ConnectionImpl.java into a service that could replaced using different providers, and then one provider could be compatible with Android. Or should we just find a solution that is compatible with everything?
