On this example, the error is "dlopen failed: "/data/app/com.arcgis.android.samples.maps.helloworld-1/lib/x86/libruntimecore_java.so" has unexpected e_machine: 40", that means the lib in the x86 folder is arm instead of x86.
I've checked and I can confirm that the lib inside arcgis .aar, /jni/x86/libruntime_core.so is ARMv5 instead of x86. They put the same ARMv5 lib in all the architecture folders. That's not a Android Studio issue. Regards, Xavier.
