Using UniFFI binding Android App#

Cedarling UniFFI binding exposes its init, authz and log interfaces to different languages and on all the different platforms, including Kotlin for Android. This section covers how to build and use Cedarling UniFFI binding in an Android app.

Prerequisites#

Rust: Install it from the official Rust website.
Android Studio: Download from the official site.

Building#

Ask toolchain manager to install support for compiling Rust code for aarch64-linux, armv7-linux, i686-linux and x86_64-linux.

    rustup target add \
        aarch64-linux-android \
        armv7-linux-androideabi \
        i686-linux-android \
        x86_64-linux-android

Run below command to build and import binding into Android project.
```
make android
```

Use make android BUILD_TYPE=release or make android BUILD_TYPE=debug to build in release or debug mode. If BUILD_TYPE is not specified, the release profile is used by default.

We have included a sample android app using Cedarling UniFFI binding for making authorisation decisions. Open the ./bindings/cedarling_uniffi/androidApp project on Android Studio and run the project on simulator.
