Where is AIDL used in Android?

AIDL is used for Binder. Binder is a mechanism to do RPC calls on/from an Android Service.

What is AIDL what data types are supported by AIDL?

– AIDL is the abbreviation for Android Interface Definition Language. – It handles the interface requirements between a client and a service to communicate at the same level through interprocess communication. – The process involves breaking down objects into primitives that are Android understandable.

What is stable AIDL?

Android 10 adds support for stable Android Interface Definition Language (AIDL), a new way to keep track of the application program interface (API)/application binary interface (ABI) provided by AIDL interfaces.

What is AIDL file?

The Android Interface Definition Language (AIDL) is a tool that lets users abstract away IPC. Given an interface (specified in a . aidl file), various build systems use the aidl binary to construct C++ or Java bindings so that this interface can be used across processes, regardless of the runtime or bitness there.

Is HIDL deprecated?

More broadly, HIDL is a system for communicating between codebases that may be compiled independently. As of Android 10, HIDL is deprecated and Android is migrating to use AIDL everywhere.

Which data type is not supported by AIDL?
