the first connect fails. This is necessary for Ipv4+ipv6 and for services hosted in redundant data centers. OkHttp initiates new connections with modern TLS features (SNI, ALPN), and falls back to TLS 1.0 if the handshake fails. Using OkHttp is easy. Its Request/response APIs are designed with fluent builders and immutability. It supports both SyNchronous blocking calls and async calls with callbacks. OkHttp supports Android 2.3 and above. For Java,

versions is a good choice. In Android 2.3 and later versions, HttpURLConnection is the best choice. Its API is simple and small, therefore, it is very suitable for Android projects. The compression and cache mechanisms can effectively reduce network access traffic and play a major role in improving speed and saving po

to start the response caching feature. The following example code shows how to enable the response cache feature in Android 4.0 and later, without affecting the previous version:[Java]View Plaincopy Private void Enablehttpresponsecache () { try { long httpcachesize = Ten * 1024x768 * 1024; //MiB File Httpcachedir = new File (Getcachedir (), "http"); Class.forName ("Android.net.http.HttpResponseCache") .

(requests header) and the returned content (Response header and content), such as:You can find that fiddler can view the data returned by the network request in various formats, including header, TextView (text), ImageView (picture), Hexview (hex), WebView (Web Form), Auth ( Proxy-authenticate header), Caching (header cache), Cookies, Raw (original data format), JSON (JSON format), XML (XML format) is very convenient.Stop

keepalive conditionVi. on the timely cessation of meaningless network requests:Sometimes some network requests may become a waste request, they not only crowding out the thread pool resources, accounting for memory, run more traffic, more power, and even cause memory leaks. For example, the user opened an activity, the activity opened a number of

Android practitioners, ten are doing network applications, not the Internet is also a local area network. Now in the world of 4G and WiFi, traffic is already floating clouds, single-use market has been quietly gone. So, do not understand the network request students to be ca

Android phone can be WiFi internet, this is good. But when there is no WiFi, how to go on Ah, 3G---> Limited traffic, watching video is not cost-effective! Here I summarize several methods for your reference.Method One: USB cable, mobile phone wired internet1, connect the phone via USB cable to the computer, check the "settings, wireless and network binding and p

First, the problem description Android applications often involve loading a large number of images from the network, in order to improve loading speed and efficiency, reduce network traffic will adopt the two-level cache and asynchronous loading mechanism, so-called two-level cache is by first get from memor

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 inevitab
