Android Aidl implements cross process communication between two apps

This paper shares an example of cross process communication between two apps implemented by Android Aidl for your reference. The specific contents are as follows

1. Service side creation

First, you need to create an Android project, and then create an Aidl file. The purpose of creating an Aidl file is to generate a stub class that inherits binder, so that binder can be used for inter process communication

The structure of the server end is as follows

Aidl code is as follows

Then create a book. Java class that implements Parcelable to transfer data

Finally, let's write a service for client binding

In this way, the server side is done, and then it's time to write the client side code

2 client side

The client side structure is as follows

First, let's talk about importing the binder generated by Android studio through Aidl into the client, importing book.java into the client, and then writing the binding of the service

Finally, call the setting button

In this way, we have realized the call of different apps of Aidl.

The above is the whole content of this article. I hope it will be helpful to your study, and I hope you can support programming tips.
