[GEAR VR] Having trouble building my project for Gear VR

[Imsopov]

I've managed to compile an app on the template project that works fine but in my own project it fails.

is it because of the size?

This hasn't been optimized for VR yet, it was mainly to see if it would compile. It will compile if I don't include the OBB file in the APK, but then when I run it in the Gear VR it shows me the download screen. If I do include the obb in the APK I get the following.

It does look like the data is too big to package in the APK (the ZIP failure). What size is the OBB if you don't select to package in APK?

Did you maybe include all the starter content in your own project? This will greatly increase the size; you should be able to cut this down greatly.

I have a similar problem to this. Attempting to build for an S6 Edge on the Gear VR. I have no clue about coding or the like and no idea where to start looking for help.
