GearVR export fails with Online Subsystem Oculus plugin enabled

I finally got around to testing some of the Online Subsystem features offered by the Oculus platform but I'm able to get an export to build with that plugin enabled using 4.15 from the Oculus github branch: https://github.com/Oculus-VR/UnrealEngine

Here's the error in the log:

Any ideas what I'm doing wrong? Is this plugin now supported for gearvr?

    Hi,

    We noticed that the standard c++ string library broke android, and have since pushed a fix.  If you pull from github you should be able to export to GearVR again

    I did that last night (got 4.15.2 unified release from Oculus github). Apparently it's totally incompatible with projects made in launcher version of UE4. Also incompatible for FMOD for 4.15.
