Android ANE - unable to find class android/support/v4/app/FragmentActivity

Hi,

I have app with target SDK 24 and own ANE for Google Play services, but it seems to fail to init on Android 4.4 with these lines in log:

12-05 12:14:30.209 7930-7930/com.amanitadesign.TestAndroidGooglePlayANE W/dalvikvm: VFY: unable to find class referenced in signature (Landroid/support/v4/app/FragmentActivity;)

The code for android/support/v4/ is part of AIR runtime, so what I should do to get it working?

I was trying to include android-support-v4.jar as a package dependency, but than app packaging fails with errors like:

dx tool failed:

Note that this is just test app so no other ANEs are used so this is not a case of this duplicity.

Any help?

Thanks,

David
