How to use Parcelable in AIDL

Question

I define a class which implements Parcelable, like this:

public class Book implements Parcelable

And I know I can use this class in AIDL file like this:

import com.okay.demo.aidl.bean.Book;
interface IBookManager {
   void addBook(in Book book);
}

But what I want to know is that can I just Parcelable in AIDL file suppose I don't know the implementation class? Can I just use Parcelable like this :

interface IBookManager {
   void addData(in Parcelable data);
}

I had tried replace Book with Parcelable, but it didn't work.

Or can not it do this in AIDL ?

Answer 1

Android documentation says you should create an AIDL file for your class Book. Your Book.aidl should look like:

import com.okay.demo.aidl.bean.Book;

// Declare Rect so AIDL can find it and knows that it implements
// the parcelable protocol.
parcelable Book;

With this new file, you can now use Book in your AIDL file:

import com.okay.demo.aidl.bean.Book;

interface IBookManager {
   void addData(in Book book);
}
