Answer 1

Eclipse doesn't just change the file extension; it uses an Android SDK tool called aidl to create a whole Java class based on the information within the .aidl file.

There's documentation on the aidl format here and it is compiled to classes based on IBinder .

The source code for the aidl tool itself can be found here , but really the best way to understand exactly what it does is to look at one of the generated .java files.
