LogDialogs: Warning: Suppressed: Android is not listed as a supported platform for this project, so may not run as expected.

Did you install the correct androidworks in the engine’s subfolder?:

Epic Games\UE_4.21\Engine\Extras\AndroidWorks\Win64\CodeWorksforAndroid-1R7u1-windows.exe

as per:

And set it up correctly in Unreal?

Also for GearVR you only need to export as Android → ASTC (not Android Multi if you’re doing that)
