Android Network Architecture-OkHttp + Volley + Gson, okhttpgson
Previously, HttpClient was encapsulated by itself. However, Volley is used for mainstream network requests, and OkHttp is also very popular.
These frameworks are not introduced. This article uses Volley to process Http requests in combination with OkHttp, and uses Gson custom requests to implement
. asyncconnect (URL, httpmethod. get, new httpconnectioncallback () {@ overridepublic void execute (string response) {text. settext (HTML. fromhtml (response) ;}}) ;}break; case R. id. http_cancal: edit_text.settext ("http: //"); break ;}}}}
In the clickevent class, we use the custom httpconnectionutil class in The onclick method. Don't rush to run it. Next, we have another step. The most important thing is the increase of permissions, to access the network
Android Network HTML viewer and androidhtml Viewer
This document provides an Android-based network HTML viewer.
Create a project. The project layout file is as follows:
Create a tool class StreamTools. java:

The previous three articles started with the most basic tcp,http protocol theory, and then introduced the two HTTP clients, httpclient and HttpURLConnection, used in Android development. In this article, let's take a look at the volley framework that is often used in Android development. First, we will look at the structure of the framework from an architectural perspective, and then understand the framewor

between the two modes. When the Android device is in host mode, it acts as a USB host and powers the bus. When the Android device is in Attachment mode, the connected USB hardware (in this case, an Android USB attachment) plays the host role and powers the bus.Figure 1.

1.Volley Introduction:
Volley is Google's launch of the Android Asynchronous network request framework and picture loading framework.
Released at the Google I/O 2013 conference.
2.Volley Features
Strong extensibility.
Android currently offers two kinds of HTTP communication methods: Android2.3 and above based on httpurlconnection,2.
Android Network Programming (4) parsing Volley from source code
1. Volley Structure
As you can see, Volley is divided into three threads: the main thread, the cache scheduling thread, and the network scheduling thread. The request is first added to the cache queue, if the corresponding cache results are found, the cache is directly read and parsed, and then the
To develop a network-based application on the Android platform, you must determine the current network connection status. The following code, as an example, describes in detail how to judge the current network situation.
First, let's look at a self-defined application class.

Android Network Programming-http sending/request service
I recently learned about Android network programming. The following are some of my experiences tonight. Share with you.
In actual application development, the app often needs to request data from the server. How does the app send requests? The following code is a
