+description: "Modernizing Android support in Rust"
+---
+
+We are pleased to announce that Android platform support in Rust will be
+modernized in Rust <version> as we update the target NDK from r17 to r25.  As a
+consequence the minimum supported API level will increase from 15 (Jelly Bean)
+to 19 (KitKat).
+
+In NDK r23 Android switched to using LLVMs `libunwind` for all architectures.
+This meant that
+1. 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 `libgcc`
+   to instead link against `libunwind`.  Following this update this workaround
+   will no longer be necessary.
+2. If a project targets an NDK between r17 and r23 it will need to be updated to
+   target r23 or newer.
+
+Going forward the Android platform will target the most recent LTS NDK, allowing
+Rust developers to access platform features sooner.
