We described the broadcast mechanism of the Android system, in essence, it is a message subscription/advertisement mechanism, so the first step to use such a message-driven model is to subscribe to the message, and for Android applications, the subscription message is actually a register broadcast receiver, This article explores how the Android app will register a broadcast receiver and where to register th

The receiver/connector mode is designed to reduce the coupling between connection establishment and service execution after the connection is established. For example, in the WWW browser, the service or "actual work" performed is to parse and display the HTML page received by the client's browser. Connection establishment is secondary and may be accomplished through BSD sockets or some other equivalent IPC mechanism. Using these patterns allows progra

In the first article, we've seen how to use intent to launch new application components, but in fact they can also use the Sendbroadcast method to broadcast messages anonymously between components.As a system-level messaging mechanism, intent can send structured messages between processes. Therefore, the broadcast receiver is implemented to monitor and respond to these broadcast Intent within the application.By using intent to broadcast an event, you
