Generated Service API

Binder generates a trait corresponding to the interface definition. trait to talk to the service.

birthday_service/aidl/com/example/birthdayservice/IBirthdayService.aidl:

1. /** Birthday service interface. */
2. interface IBirthdayService {
3. /** Generate a Happy Birthday message. */
4. String wishHappyBirthday(String name, int years);
5. }

Generated trait:

1. trait IBirthdayService {
2. fn wishHappyBirthday(&self, name: &str, years: i32) -> binder::Result<String>;
3. }

Your service will need to implement this trait, and your client will use this trait to talk to the service.

  • The generated bindings can be found at out/soong/.intermediates/<path to module>/.
  • Point out how the generated function signature, specifically the argument and return types, correspond the interface definition.
  • String for an argument results in a different Rust type than String as a return type.
