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
For many of the pursuit of simplicity, to get rid of the shackles of wire users, the wireless mouse becomes preferred, but the wireless mouse is very convenient to use, but sometimes also encounter some trouble, such as wireless mouse receiver lost or broken, resulting in wireless mouse can not use how to do?

Explanation of Intent in Android (2) Introduction to using Intent to Broadcast events and Broadcast Receiver
The first article explains how to use Intent to start new application components. However, they can also use the sendBroadcast method to anonymously broadcast messages between components.
As a system-level message transmission mechanism, Intent can send structured messages between processes. Therefore, you can implement the Broadcast

In Android development, broadcast receiver has a lot of application scenarios. Broadcast, is a global listene
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
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
In spark streaming, for Receiverinputdstream, it's a real receiver, used to receive data. Receiver can have many and run on a different worker node. These receiver are managed by Receivertracker.In the Start method of Receivertracker, a message communication body Receivertrackerendpoint is created:/** Start The endpoint and r

In a connection-oriented network system, ApplicationsProgramA large number of configuration proxies are usually used to establish connections and initialize services. These configurationsCodeMost services process data exchanged between connection endpoints independently. Therefore, the tight coupling between the configuration code and the Service Processing code is not ideal, because the follo
After the system or user application sends a broadcast, the broadcast receiver that meets the conditions will receive the broadcast. Generally, broadcast sending is implemented through the sendBroadcast (Intent intent) (or sendStickyBroadcast) or sendOrderedBroadcast () methods (these two sending Methods correspond to two different broadcasts respectively, one is normal Broadcast and the other is ordered Broadcast.) intent is the Intent to be Broadcas

In essence, the broadcast mechanism of the Android system is a message subscription/publishing mechanism. Therefore, the first step to use this message-driven model is to subscribe to messages. for Android applications, subscribing to a message is actually registering a broadcast receiver.
Two registration methods are available: static registration and dynamic registration. In the Broadcast Mechanism of Android, the priority of Dynamic Registration is
This section describes how to create a broadcast, how to send an unordered broadcast and ordered broadcast, and how to listen to text messages and outgoing calls. (when we send text messages and make phone calls, the system sends a broadcast, we can intercept this broadcast to listen for text messages and listen for outgoing calls ).
