Instance creation fails with VK_ERROR_LAYER_NOT_PRESENT

[raphlinus]

Environment information:

• AGI version: Version 1.0.0:4ddd08c5546200a14141b75639a4b758fb2fadd2
• Host OS: Windows 10
  If tracing on Android:
• Device model: Pixel 4
• Android Version: 11, RQ2A.210305.006

Bug description
When creating a Vulkan instance when started from AGI, the vkCreateInstance call fails with VK_ERROR_LAYER_NOT_PRESENT.

Reproduction steps
Steps to reproduce the behavior:

1. Check out Add example Android apk linebender/vello#82. Install "cargo apk" tool, and build this APK with cargo apk run --example android.
2. Try to capture trace using AGI.
3. Activity crashes with VkError(ERROR_LAYER_NOT_PRESENT)

Note: this is a Vulkan app written in Rust, using the ash bindings. It's entirely possible I'm doing something wrong. I have been able to get validation output, using the steps outlined in Vulkan validation layers on Android. I'm also able to capture traces from the spinning cube demo bundled with AGI.

Looking at the instance creation code, I'm not doing anything particularly funny, or different from the sample code here. I get the same error whether I ask for the VK_LAYER_KHRONOS_validation layer or not.

Could you give a quick try to our "dev-releases" see if that unblocks you? You can grab the latest AGI dev-release from:
https://github.com/google/agi-dev-releases/releases/latest

Please let us know if the bug reproduces with the latest dev-release.

I tried cargo-apk but it seems to systematically fail, whichever the args I give to it:

~/work/piet-gpu (android2)$ cargo-apk run --example android
Error: Invalid args.
~/work/piet-gpu (android2)$ cargo-apk build
Error: Invalid args.

The new version works, thanks!

To reproduce, you don't call cargo-apk directly, but use cargo: so "cargo apk run --example android". It does also need to be in the piet-gpu subdirectory of the repo for that to work.
