standard network application uses a standard port address. For example, a Web server uses port 80. You can view the registered port addresses in/etc/services. The IP protocol layer can also use different physical media to transmit IP packets to other IP address hosts. You can add protocol headers to these media sets. For example, the Ethernet protocol layer, PPP protocol layer, or slip protocol layer. Ethernet can be connected to multiple hosts at the same time, and each host has an ethernet ad

That is, if one of the hosts in the

The IP address consists of three types: unicast address (destination is a single host), broadcast address (destination is all hosts on a given network), and multicast address (destination is all hosts within the same group).　　broadcast and multicast only apply to UDP, It is important that they transmit messages to multiple receivers simultaneously.　　TCP is a connection-oriented protocol that means that ther

from 224 to 239. the first byte of the Class d ip address starts with "1110". It is a specially reserved address. It does not point to a specific network. Currently, this type of address is used in multi-point broadcast (Multicast. A multicast address is used to address a group of computers at a time. It identifies a group of computers that share the same protocol. Multicast over an IP network is generally achieved through multicast IP addresses. Mul

Broadcast content can be either custom information or Android system information. For example, changes in the network connection, changes in battery power, changes in system settings, receipt of a new text message 、、...... such as1.

can be an IP datagram, or it can be a shard of an IP datagram.Broadcast and multicastThere are three types of IP addresses: unicast addresses, broadcast addresses, and multicast addresses.Broadcast and multicast are only applied to UDP, and they are important for applications that need to transmit messages to multiple receivers at the same time. TCP is a connection-oriented protocol that means that there is a connection between two processes running

Introduction to the-------------------------------------- broadcasting mechanism ---------------------------------------------The broadcast mechanism in Android is very flexible, and every application in Android can register its own broadcasts of interest, and the program will only receive the broadcast content that it cares about, which may come from the system or from other applications.Android provides a

The four basic components of Android are Activity,service services, content provider contents providers, Broadcastreceiver broadcast receivers.First, Activity(1) In an application, an activity is usually a separate screen that shows some controls that can also listen and handle the user's events to respond.(2) Communication between activity through intent. In the description structure of intent, there are two most important parts: the data correspondi

The contents of this chapter include:1) Overview of UDP2) A simple example of a broadcast applicationSo far, all of the examples we have used are protocol-based protocols, such as TCP, in which we will focus on protocols without connection X (User Datagram Protocol UDP), This protocol is often used in situations where performance requirements are extremely high but allow a small amount of packet lossLet's start with the concept of UDP, explain its fea

Broadcastreceiver (broadcast receiver) is one of the four main components in Android. The following is an overview of broadcastreceiver in Android DOC:① A broadcast receiver is a component that focuses on receiving and processing broadcast notifications. Many broadcasts originate from system code, such as notifying time zone changes, low battery, taking a pictur

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

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

For system-level message notifications, Android introduces the concept of broadcast. And the broadcast in Android is more flexible because the application can publish its own broadcasts and receive broadcasts. Sending broadcasts requires the use of intent to send, while receiving broadcasts requires the Broadcastreceiver class to receive broadcast operations by o
