AIDL Interfaces

You declare the API of your service using an AIDL interface:

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

1. package com.example.birthdayservice;

3. /** Birthday service interface. */
4. interface IBirthdayService {
5. /** Generate a Happy Birthday message. */
6. String wishHappyBirthday(String name, int years);
7. }

birthday_service/aidl/Android.bp:

1. aidl_interface {
2. name: "com.example.birthdayservice",
3. srcs: ["com/example/birthdayservice/*.aidl"],
4. unstable: true,
5. backend: {
6. rust: { // Rust is not enabled by default
7. enabled: true,
8. },
9. },
10. }

• Note that the directory structure under the aidl/ directory needs to match the package name used in the AIDL file, i.e. the package is com.example.birthdayservice and the file is at aidl/com/example/IBirthdayService.aidl.
