The answer is actually pretty simple and with no workaround. If you look at the ArcGIS runtime for Android, you will notice that it has both a jar and native *.so libraries. Obviously, the jar is truly cross platform. However, java code has the ability to call into native libraries which prevents the Java code from being cross platform unless the native libraries are compiled for all the platforms you want. ESRI only distributes armeabi and armeabi-v7a *.so libraries. Therefore, when you try to run it on an Intel based emulator, it will try to find an x86 version of the native library and will fail causing the app to crash immediately. that is what the "UnsatisfiedLinkError" is complaining about in your log.
Therefore, ESRI needs to recompile their native library for x86 and distribute that *.dll along with the ArcGIS runtime for Android. Until then, nothing you can do.
