Android Serivce advanced AIDL

Note: AIDL is required. 1. Create an aidl file first, as shown in IPerson. aidl.

2. After creation, refresh the file. You can see the Iperson. java file implemented by the proxy under R. gen.

3. Implement the aidl interface. For example, IpersonImpl. java implements the interface in IPerson. aidl.

4. Use the Service to expose the interface to the client for calling. MyRemoteService. java

5. The client can call this interface.

Postscript: data is called between two applications.
