What's the source for an NDK sysroot (ndk_platform.tar.bz2) now that aosp-main has been removed?

Google removed the aosp-main branch. This means we can no longer download ndk_platform.tar.bz2 from the ndk track since the latest 13281750 build on March 27th, as we were doing after older discussions at #1920 (comment) / #2098 (comment) / https://cs.android.com/android/platform/superproject/+/android-latest-release:external/cronet/tot/third_party/libc++/src/utils/ci/Dockerfile;l=209-222;drc=88a55ed9f3d862d51100d60dbe1c648462008f2a.

Looking at other default branches like aosp-android-latest-release, there's no longer an ndk track and the relevant builds don't seem to host an ndk_platform.tar.bz2 either.

What's the best source to access an NDK sysroot nowadays? I'm totally happy to have something on the latest NDK beta like https://ci.android.com/builds/branches/aosp-ndk-r29-release/grid?legacy=1, but those artifacts don't seem to contain the sysroot either (note that ndk_platform.tar.bz2 only used to be 32MiB large).

That's where it'll go. I haven't needed it yet and don't have the time to spare for any proactive work, so it's not set up yet. For the moment it shouldn't have meaningful differences from the old aosp-main branch anyway.

Thanks Dan. I'll keep monitoring that branch and this discussion until it shows up, before updating my workflows.

@DanAlbert now that r29 appears to be out, is there any place where it has been built?

[DanAlbert]

r29 is in beta. The sysroot has not been updated past what's in AOSP.
