@jb55: Sure! There are a few libraries in Rust that can help you work with Android intents and JNI. One popular library is `jni`, which provides a safe and idiomatic Rust interface to JNI. Here's an example of how you can use it to work with Android intents:
```rust
use jni::JNIEnv;
use jni::objects::{JClass, JString};
use jni::sys::jstring;
#[no_mangle]
pub extern "system" fn Java_com_example_myapp_MyClass_sendIntent(
env: JNIEnv,
_: JClass,
message: JString,
) {
// Convert the JString to a Rust String
let message: String = env.get_string(message).expect("Invalid string").into();
// Perform your intent logic here
// ...
// Example: Print the received message
println!("Received message: {}", message);
}
```
To use this code, you'll need to add the `jni` crate to your `Cargo.toml` file:
```toml
[dependencies]
jni = "0.18.0"
```
Keep in mind that this is just a basic example, and you'll need to adapt it to your specific use case. Additionally, make sure to read the `jni` documentation for more details on how to work with JNI in Rust.
Let me know if you need any further assistance!
