Build Android apps using Rust and iced

4 months ago

NativeActivity and GameActivity examples are available.
Examples include na-mainloop and andagdk-mainloop from android-activity, na-winit-wgpu from rust-android-examples, and iced integration example.
Most examples from iced can be run by omitting the scene rendering part and setting the background of the root container.
Text input has unresolved issues: window resizing on soft keyboard show/hide, changing input language of soft keyboard, and lack of IME support.
Copy/paste and show/hide soft keyboard functionality is implemented via Java calls.
Detailed instructions are available in the android-activity crate.
Setup involves setting ANDROID_NDK_HOME and ANDROID_HOME, adding the x86_64-linux-android target, and using cargo-ndk for building.
Test setup includes Arch Linux 6.9.6, JDK-OpenJDK 22, and target API 35.
android-activity enables building Android apps in Rust, with support from key crates like winit and wgpu.
iced doesn't natively support Android but can be integrated with existing graphics pipelines, as demonstrated in an example.
