This answer worked for me and I was able to build the project in Android Studio:
However, at runtime, I was getting a java.lang.UnsatisfiedLinkError at the line in MainActivity.java:
System.loadLibrary("jnix");
libjnix.so is missing from ohbee/android/streamer/*, but the armeabi binary is in ohbee/android/streamer2/libs/armeabi. When I copied this into my src/main/jniLibs/armeabi, I was able to run the application on Samsung Galaxy Note S3. It streams the camera into an RTPSink instance with a dummy address.
Obviously, targets which are not armeabi will not work (so virtual devices don't work), and I haven't been able to find the source for the jnix libs (only the headers).
