AIDL Interface

What is AIDL file?

Files ending with the extension .AIDL contain source code that defines an interface for Android system applications. Files saved in the Android Interface Definition Language are in text format, and their syntax is compatible with the Java programming language. Files allow for precise specification of how different applications or system functions communicate.

Usage of .AIDL Files in Android Applications

An AIDL file should be stored in the source directory of the Google Android SDK project - src. Each AIDL file must include:

  • an interface declaration,
  • method signatures,
  • absence of static fields,
  • possible import of non-basic data types.

This allows for the automatic creation of appropriate files for interfaces during the project build. As a result, the IBinder.java interface file and the interface implementation created by the developer will be generated.
