Description

Discovered this while doing RC candidate testing for 4.13

Works fine in all other use cases:
Nougat devices that support Vulkan
Marshmallow devices that support Vulkan
Marshmallow devices that don't support Vulkan.

Steps to Reproduce
  1. Package a project for es2 and Vulkan.
  2. Install on a device running Android 7.0 that does not support Vulkan (Nexus 9 4068)
  3. Launch the app.
  4. Observe the crash.
