This looks fine. Can you confirm that your APK with libs from the AAR is failing on the emulators, but not on a real device, and that it is always working when you manually package the libs ? In that case, can you also check if this behavior happens only on x86 emulators, and not arm emulators/arm devices ?
My first guess would be that when you're using the AAR, ProGuard optimizes out a native method that you aren't using, and then load is failing because ART expect to have all the methods declared on both sides. But the fact that it's also crashing on a API 17 emulator invalidates this... You should be able to get more information than just "dlopen failed". Especially in the emulators since checkJNI is enabled by default. Maybe you've filtered out the JNI debug informations: they should be tagged D/dalvikvm on the API 17 one. btw, if you need a x86 device running Lollipop, there are two on the market right now: the Nexus Player and the Trekstor Xintron Tab 7: http://www.amazon.de/dp/B00NQBW7BU/ Regards, Xavier Hallade.
