When verifying an APK's JAR signature, apksig library and apksigner tool can report an error along the lines of
----
JAR signature META-INF/DELROID.RSA uses digest algorithm 2.16.840.1.101.3.4.2.1 and signature algorithm 1.2.840.113549.1.1.1 which is not supported on API Levels [[12, 17]]
---

The wording of the error is causing confusion among developers who use the library/tool (e.g.,

https://stackoverflow.com/questions/44874386/apk-upload-failed-for-alpha-version-errors-from-apksigner-digest-algorithm-and) and should thus be improved.

Hi,

would you try to boot emulator with this command line flag:

-feature -Vulkan

and let us know if it fixes the issue for you? Also would you tell us what graphics card you are using and what is the graphics driver version?

The feature flag did solve the issue for me. Thank you very much. I don't use a dedicated graphics card. Only the internal one from the CPU.

Marked as fixed.

Your integrated GPU is supposed to support Vulkan 1.2. I would need more work to figure out why it crashes without that flag.
