+# Matrix rust components kotlin
+
+This project and build scripts demonstrate how to create an aar and how to import it in your android projects.
+
+## Prerequisites
+
+* the Rust toolchain
+* UniFFI - `cargo install uniffi_bindgen`
+* cargo-ndk < 2.12.0 `cargo install cargo-ndk --version 2.11.0`
+* android targets (e.g. `rustup target add \
+  aarch64-linux-android \
+  armv7-linux-androideabi \
+  x86_64-linux-android \
+  i686-linux-android`)
+
+## Building the SDK
+
+To build the full sdk and get an aar you can call :
+`./bindings/kotlin/scripts/build_sdk.sh /matrix-rust_sdk/bindings/kotlin/sample/libs`
+where the parameter is the path for the aar to go
