I. Descriptive narrative of the problem Android applications often involve loading a large number of images from the network, to increase load speed and efficiency, and to reduce network traffic using level two caching and asynchronous loading mechanisms. The so-called level two cache is obtained from the me

1. Introduction Currently, images are inevitably used in Android applications. Some images can be changed and need to be pulled from the network at each startup, there are many such scenarios in advertising spaces and pure image applications (such as Baidu meipai. Now there is a problem: If you pull images from the network every time you start, it will inevit

Topic:When the network is bad, how to optimize the load picture of the network when stalling?Ideas:Consider both the loading of the picture itself and the storage of the phoneWorkaround: 1. Find a replacement for an existing picture formatIn a number of image formats, Google's WEBP is selected. The reason for this is simple: high compression efficiency and good support for

This method is mainly about how to carry out network data capture on Android and iphone , for example, if we want to catch a network communication request for an app (Weibo, ink weather).The advantages of the tcpdump with the Wireshark clutch are:(1) no root (2) for Android and iphone (3) easier and easier to operate (

Because of the limited mobile phone traffic, when using Android phones, we should consider for users as much as possible to consume less user traffic, in applications, the display of network images is undoubtedly the most traffic-consuming. Therefore, we can compress images

ObjectiveIn the first three articles that teach you about the Android network framework, from the basic structure to the code implementation, we analyze how a simple network framework should work, and how to handle the code in the face of a variety of requirements, and learn some simple object-oriented design principles while in-depth understanding of the

Introduction Android applications are now inevitable to use the picture, some pictures can be changed, need to start each time from the network pull, this scene in the use of advertising and pure picture applications (such as Baidu Beauty shoot) more. Now there is a problem: if every time you start pulling pictures from the network, it is bound to consume a

steps to create the server are as follows: 1, specify a port to instantiate a serversocket;2, call ServerSocket's accept method to cause blocking while waiting for the connection; 3. Get the socket stream at the bottom to read and write, 4, encapsulate the data into a stream, 5, read and write the socket, 6, close the open stream. The steps to create the client are as follows: 1. Instantiate the socket via IP address and port, request a connection server, 2, get the stream on the socket for rea

I recently developed an android network packet capture tool. I have searched the internet for a long time. No clue found So we need to work hard on the Linux layer. Therefore, tcpdump in Linux is used to implement the packet capture function. To define tcpdump in a simple way, dump the traffic on a network is a packet

Suppose not to do whatever treatment. Load pictures directly with the network in the case of fast speed, there may be no bad feeling. But suppose you use mobile traffic or a bad network. The problem comes, or the user complains that the traffic is being used too much. Either complain that the picture is loading too slo

today, UDP is a very practical and feasible network transport protocol. As with the well-known TCP (Control Protocol) protocol, the UDP protocol is directly at the top of the IP (Internet Protocol) protocol. According to the OSI (Open Systems Interconnection) Reference model, both UDP and TCP belong to the Transport layer protocol. The main function of UDP protocol is to compress the network data
