# Example of building android app with iced

There are [NativeActivity](./NativeActivity) and [GameActivity](./GameActivity) examples here.

Based on several other examples:

 - `na-mainloop` and `agdk-mainloop` from

   [android-activity](https://github.com/rust-mobile/android-activity/tree/v0.6.0/examples)

 - [na-winit-wgpu](https://github.com/rust-mobile/rust-android-examples/tree/main/na-winit-wgpu)

   from `rust-android-examples`

 - [integration](https://github.com/iced-rs/iced/tree/0.13.1/examples/integration)

   from `iced`

## Preview

You can also run most of the examples from iced.

For this omit the scene rendering part and set the background of the root container.

## Watch

## Text input

Text input partially works, unresolved issues:

- window doesn't resize on show/hide soft keyboard

- how to change input language of soft keyboard

- ime is not supported

Copy/paste and show/hide soft keyboard is implemented by calling Java

## Building and running

Check `android-activity` crate for detailed instructions.

During my tests I was running the following command and using android studio afterwards:

```bash

export ANDROID_NDK_HOME="path/to/ndk"

export ANDROID_HOME="path/to/sdk"

rustup target add x86_64-linux-android

cargo install cargo-ndk

cargo ndk -t x86_64 -o app/src/main/jniLibs/  build

```

My setup is the following:

- archlinux 6.9.6

- jdk-openjdk 22

- target api 35

## How it works

Thanks to `android-activity` we can already build android apps in Rust, and

key crates such as `winit` and `wgpu` also support building for android.

`iced` doesn't support android out of the box, but it can be integrated with

existing graphics pipelines, as shown in

[integration](https://github.com/iced-rs/iced/tree/0.13.1/examples/integration) example.

As a result, it was possible to convert existing example running `winit` + `wgpu` to

use `iced` on top.
