NDK version 29.0.14206865 broken

[setoelkahfi]

I have two version of Android NDK in the sdk folder: 29.0.14033849 and 29.0.14206865

Using this export NDK_HOME="$ANDROID_HOME/ndk/$(ls -1 $ANDROID_HOME/ndk)" from the docs will not possible since it will list two versions. So, I hardcoded the environment variable to use the 29.0.14033849. But the cargo tauri android dev apparently pick the latest one:

➜  splitfire-desktop git:(feature/sfai-admob-android) ✗ cargo tauri android dev
        Info Using installed NDK: /Users/setoelkahfi/Library/Android/sdk/ndk/29.0.14206865

This was working before, until I updated my Android Studio to the latest:

Android Studio Otter | 2025.2.1 Patch 1

Is there a documented supported NDK version? I'm trying to update my NDK to the latest (29.0.14206865) and it makes my build failed. Not sure if the CMAKE version is also related, because I updated it to 4.1.2 from 4.1.1 as well.

Is there a documented supported NDK version?

Well in theory all available versions should work, we recommended 29+ for the 16kb page size requirement. patch updates like these should also not contain any breaking changes that should affect us (nor should major updates with how we use the ndk tbh).

But the cargo tauri android dev apparently pick the latest one

I'll check that out. - EDIT: Seems like it only cares about ANDROID_HOME and then selects versions it finds. Can you open an issue for that please?

I assume that is what #14518 is for? Please include how exactly it makes your build fail in that issue.

Several things happening here:

• I updated my Android Studio code to Otter.
• I updated the NDK version.
• I update the CMake version.
• I updated the gradle deps of the plugin I'm trying to integrate.

Yes, it is related since both projects are using the same plugin.

I reverted the NDK and CMake version to the know working versions (NDK 29.0.14033849, CMake 4.1.1) now and one of the project is successfully built now after fixing the plugin deps. I'm not sure which one was the problem.
