Thanks,
upgrading to API level 21 did fix that particular problem. Btw, can
you advise on which of the libraries I need to load, and in what
order?
I tried this:
static {
Log.d(TAG, "Loading native libraries...");
System.loadLibrary("connectivity_abstraction");
System.loadLibrary("octbstack");
System.loadLibrary("oc");
System.loadLibrary("oc_logger");
System.loadLibrary("gnustl_shared");
System.loadLibrary("ca-interface");
System.loadLibrary("ocstack-jni");
Log.d(TAG, "Done loading native libraries.");
}
and Crosswalk complains about a mysterious (i.e. not better specified)
UnsatisfiedLinkError:

If I try to omit `System.loadLibrary("ocstack-jni");`, then the JNI
loading completes with no errors, but when using `PlatformConfig` I
get:
E/XWalkExtensionManager( 2461): Error in calling methods of external
extensions. java.lang.reflect.InvocationTargetException
Unfortunately there are no more details in logcat.
Ideas?
Thanks!
