George, Thanks for the reply. What is the recommended way of including the iotivity libraries (all architectures) in an Android app?
If each architecture specific library (.aar file) is included as a dependency in the Gradle build file then a debug version of the app will run. However, a release build is not possible because of duplicate classes exist in the packaged classes.jar file. We’ve tried unpacking all .aar files and extracting out the shared objects (.so files) into an Android module, which will allow for a release .apk to be built. However, we now see runtime errors like: java.lang.UnsatisfiedLinkError: JNI_ERR returned from JNI_OnLoad in "/data/app/xxx.xxx.xxx/lib/arm/libocstack-jni.so” Basically, we need to support as many architectures as possible. From a client perspective, we need all architectures or the app is not useful. Getting back to your question, yes, we are interested in enabling a universalAPK. Thanks!
