You can test the template app at <https://emilk.github.io/eframe_template/>.

### Android build

Requires Android Studio, Android SDK, Android NDK, kotlin and gradle.

We use [xbuild](https://github.com/rust-mobile/xbuild) to build for android.
1. Install the required target with `rustup target add aarch64-linux-android`.
2. Install xbuild with `cargo install --locked xbuild`.
3. Run `x devices` to show connected devices. Make sure chosen device has enabled installation via usb.
4. Run `x run --device chosen_device` to compile and run on that device.

## Updating egui

As of 2023, egui is in active development with frequent releases with breaking changes. [eframe_template](https://github.com/emilk/eframe_template/) will be updated in lock-step to always use the latest version of egui.
