Java, Kotlin and C++.

The languages with tier 1 support on Android SDK tooling for app development, properly configured out of the box after a SDK full install.

Which by the way, also includes a phone emulator to try out your stuff, including simulation of hardware events.

No need to get a phone.

I just tried this and... no C++. You can add the NDK and start building stuff with C++, but that's also exactly how the Rust offering works. If the result was actually a properly configured out of the box C++ development environment that would be pretty nice besides the Android stuff, but it isn't, the actual result out of the box is you get to pick Java or Kotlin.

You can do C++ native development for Android, but only via basically the same route as Rust, there's just not the huge gap you implied.

Since when does Rust appear as language selection on the NDK installer?

Has out of the box support on Android Studio for:

- mixed language debbugging

- project templates wizard

- code completion and linting

- JNI bindings generation

- two way editing between native JNI wrappers and Java/Kotlin native method declaration

- packaging of Android libraries for native code

And for game developers, if they so which, plugins for Visual Studio with similar capabilities.

In both cases, official support from Android team if there are issues with the above tooling.

Apparently you haven't tried enough, if you think bare bones NDK integration with cargo is enough for Android shops.

Maybe Rust will get on https://developer.android.com some day, but it isn't there today, even despite the fact that it is being used for Android internals, there is zero documentation on how to write Android drivers in Rust.

https://source.android.com/docs/core/architecture

So lets not pretend it is the same effort using Rust on Android, as it is for the official SDK languages.

Since editing window is already out, I am not arguing against Rust, and would welcome first class support for Rust on the Android tooling (Android/VS Studios, NDK, AGDK, Modules/Bundles) and being visible across https://developer.android.com documentation.
