faketruth b6138129e6 Android: I'm probably using a lot of bad practices, but the app looks somewhat better now and polls the server status
Android: Put quite some testing code in ToJava.h and app-android.cpp ... I still can't send log messages to Java. The issue is threads, I can't use JNI stuff from threads that were not created by Java (at least not easily)
