Hi Eric,
thanks for the answer - i should have mentioned I had set that to 19 already as you have it in your screenshot.
Basically I did exactly as the gear vr setup docs: https://docs.unrealengine.com/latest/INT/Platforms/GearVR/QuickStart/index.html
except I cannot do:
https://docs.unrealengine.com/latest/images/Platforms/GearVR/QuickStart/2/GVR_Android_SDK_Setup.jpg
as I get the build error as in my original post. I installed the android works with the default settings also as per the docs.
only “latest” works for me for NDK level - android-19 results in the unknown build error.
EDIT: I should mention I’m using a forked 4.9 with this change in it:

it appears using ‘android-19’ in the binary 4.9 is working - any ideas what i should build in Visual Studio to allow me to build with this setting in a source code 4.9??
