Currently using a very annoying workaround where I strip the duplicated classes from the aar file, and then include it as a local dependency:
# Download original
curl http://central.maven.org/maven2/com/facebook/conceal/conceal/2.0.2/conceal-2.0.2.aar > conceal-2.0.2.aar
# Unpack aar
unzip conceal-2.0.2.aar -d temp-folder
# Strip duplicate so files
rm jni/*/libfb.so
# Unpack classes
cd temp-folder
unzip classes.jar -d temp-folder
# Strip duplicate classes
rm -r temp-folder/com/facebook/{jni,proguard,soloader}
# Pack classes
jar cvf classes.jar -C temp-folder/ .
rm -r temp-folder
# Pack aar
cd ..
jar cvf conceal-2.0.2-stripped.aar -C temp-folder/ .
rm -r temp-folderfrom conceal.

@OleksandrKucherenko , I followed your approach but after that native library loading is failing.
Throwing "libconcealjni.so" file is not found. Did you face any such issue..?

Yes, I saw that before... it happens due to the not properly found @aar file.
The workaround is to divide the build process into two steps:
- repack and compose a patched aar
- copy patched aar into project folder and include it directly (issue is in gradle android plugin that cannot recognize aar archive, it only understands well JARs)

We had patched the aar according to @LinusU. But still facing the error. By the way, we are using conceal 2.0.2
