FBReader has now been successfully built using Android Studio, but is missing the necessary binaries (*.so)
To compile the binaries from the source, navigate to where you extracted the NDK
Execute the following command in your shell:
ndk-build -C %userprofile%\AndroidStudioProjects\FBReaderJ\fBReaderJ\src\main\jni
The binaries should be automatically placed into the appropriate directories (%userprofile%\AndroidStudioProjects\FBReaderJ\fBReaderJ\src\main\lib)
Finally, rebuild the project. FBReader should now run without issue on the emulator/on your device.
