There are NativeActivity and GameActivity examples here.
Based on several other examples:
iced integration example
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.
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
Check android-activity crate for detailed instructions.
During my tests I was running the following command and using android studio afterwards:
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
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 example.
As a result, it was possible to convert existing example running winit + wgpu to
use iced on top.
