Updating the Android NDK in Rust 1.68
Jan. 9, 2023 · Android Platform Team
We are pleased to announce that Android platform support in Rust will be modernized in Rust 1.68 as we update the target NDK from r17 to r25. As a consequence the minimum supported API level will increase from 15 (Ice Cream Sandwich) to 19 (KitKat).
In NDK r23 Android switched to using LLVM's libunwind for all architectures.
This meant that
- If a project were to target NDK r23 or newer with previous versions of Rust
a workaround
would be required to redirect attempts to link against
libgccto instead link againstlibunwind. Following this update this workaround will no longer be necessary. - If a project uses NDK r22 or older it will need to be updated to use r23 or newer. Information about the layout of the NDK's toolchain can be found here.
Going forward the Android platform will target the most recent LTS NDK, allowing Rust developers to access platform features sooner. These updates should occur yearly and will be announced in release notes.
