UDP, broadcast and Multicast (7), udp Broadcast (Reference) TCP/IP explanation, Volume 1: Protocol UDP is a simple datagram-oriented transport layer protocol. Each output operation of a process generates a UDP datagram and assembles it into an IP datagram to be sent. UDp datagram is encapsulated into IP datagram format, for example: UDP Header The fields of the UDP header are as follows: The port number i

Simple implementation of the custom broadcast (broadcast) mechanism First, define a receiver in the Manifset file and set the Intent-filter For example: The next step is to set up a custom broadcast in the activity, as follows: Intent Intent = new Intent ();Intent.setaction ("Com.neter.broadcast.receiver.SendDownXMLBroadCast")

Broadcastreceiver can not only receive system broadcasts, but also receive customized broadcasts1. Define a broadcast receiver Copy Code code as follows: public class Myreceiver extends Broadcastreceiver { Public Myreceiver () { LOG.I (TAG, "myreceiver"); } Getaction () of intent can be used to distinguish between different broadcasts received @Override public void OnReceive (context arg0, Intent arg1) { String action=intent.get

Differences between local broadcast and global broadcast and their implementation principles I. Differences between local broadcast and global broadcast 1. Local broadcast: broadcast events sentNot obtained by other applications,

What is a broadcast In Android, broadcast is a widely used mechanism for transmitting information between applications. Let's use a radio station for an analogy. We usually use radio radios to do this: a lot of different radio stations send their content on a specific frequency, and our users just need to tune in to the radio to listen to their content. The broadcasting mechanism in Android is similar to t

First, broadcast Sender Broadcast receiver Introduction 1. Broadcast Receivers The broadcast receiver is simply the Java class that receives the broadcast intent, and this Java class inherits the Broadcastreceiver class and overrides: public void OnReceive (context conte

1, in the mobile phone we open up live, and then click on the "Live button" and then find "live title" to enter and then find the "Start Live" button to enter the Live room 2, into the live room, you can click on the Beauty button to open the beauty mode (default is open) can direct live It means that as long as we open directly will automatically open the beauty function, we can try the above method, but up live broadcast beauty l

1. Introduction of broadcast senders and broadcast receivers 1. Broadcast Receiver The broadcast receiver is simply a Java class that receives the broadcast intent. This Java class inherits the broadcastreceiver class and is rewritten as follows: Public void onreceive (co

In Android, some operations will be sent after the broadcast, such as sending a text message, or a phone call, if a program received the broadcast, will do the appropriate processing. This broadcast has something in common with the radio broadcasts in our traditional sense. It is called broadcasting because it is only responsible for "saying" regardless of whethe

Conflict domain (physical segment): a collection of All workstations connected to the same wire, or a collection of all nodes on the same physical network segment or nodes competing for the same bandwidth over Ethernet. This domain represents the region in which conflicts occur and spread. This region can be considered as a shared segment. In the OSI model, the conflicting domain is regarded as the first layer. devices connected to the same conflicting domain have hub, reperter, or other devices

When a situation occurs on an Android system, all programs must be notified of processing, such as low power, and the broadcast intent object can be used to broadcast information.The operating mechanism consists of two parts: The program that sends out the intent object, the program that listens to the broadcast information (
