Looks like the failure is related to the changes in 5e37d3c

/cc @katre Can you please take a look?

As indicated in android.yml, the problem is that this example does not use the new Android platforms flags, it's using the legacy flags, which aren't supported in Bazel at HEAD.

Using Bazel 6.4.0, the build works:

$ USE_BAZEL_VERSION=6.4.0 bazel build --noincompatible_enable_android_toolchain_resolution --fat_apk_cpu=arm64-v8a,x86 --android_crosstool_top=@androidndk//:toolchain --enable_bzlmod  //app/src/main:app

INFO: Elapsed time: 0.350s, Critical Path: 0.01s

I'll try updating the flags and see if that works, but last time I tried I ran into bazelbuild/rules_android#77.
