ndk 0.9 and fix thread-safety interactions (#956)
Most changes were copied over from my `wry` PR at https://github.com/tauri-apps/wry/pull/1296. Most notably a `&ThreadLooper` is now passed to `wry::android_setup()` because we have one, and it gives important safety guarantees when it comes to registering callbacks on this looper, without (unnecessarily!) requiring `Send`. A thread-local requirement already exists for the `JNIEnv` that is passed around anyway. Also note that certain workarounds and illogical inverted passes around `key_code()` handling are no longer needed, as the `ndk` crate now passes an `enum` with the raw `i32` around so that the `.into()` conversion for `i32` (the correct type) now becomes lossless.
Cross-platform application window creation library in Rust that supports all major platforms like Windows, macOS, Linux, iOS and Android. Built for you, maintained for Tauri.
Cargo Features
TAO provides the following features, which can be enabled in your Cargo.toml file:
serde: Enables serialization/deserialization of certain types with Serde.
Platform-specific notes
Android
This library makes use of the ndk-rs crates, refer to that repo for more documentation.
Running on an Android device needs a dynamic system library, add this to Cargo.toml:
[[example]]
name = "request_redraw_threaded"
crate-type = ["cdylib"]
And add this to the example file to add the native activity glue:
#[cfg_attr(target_os = "android", ndk_glue::main(backtrace = "on"))]
fn main() {
...
}
And run the application with cargo apk run --example request_redraw_threaded
Linux
Gtk and its related libraries are used to build the support of Linux. Be sure to install following packages before building:
Arch Linux / Manjaro:
sudo pacman -S gtk3
Debian / Ubuntu:
sudo apt install libgtk-3-dev
Acknowledgement
This is a fork of winit which replaces Linux's port to Gtk. In the future, we want to make these features more modular as separate crates. So we can switch back to winit and also benefit the whole community.
