Rt.. I previously felt that Android network communication is amazing, magic ... Recently learned the network knowledge, now to summarize how to doWell, let's take an example to illustrate the principle.The use of this demo:1. Users can access a Web page2. The user submits the user name and password to the HTTP server, displaying the submitted content in the Tomcat console.Let's start by introducing how to access the Web pageLook at the codePackage Com
The latest version of the SDK adds the phrase "type_orientation this constant is deprecated. Use Sensormanager.getorientation () instead. This means that the method has been canceled, and the developer uses sensormanager.getorientation () to get the original data.In fact, the Android get direction is obtained by the magnetic field sensor and the accelerometer sen
This article illustrates how Android uses the sensor sensor to get the direction of a user's movement. Share to everyone for your reference, specific as follows:
Today continue to share a second important sensor, in fact, to get the direction of the things should be very simple, in the previous article to see that there is a type_orientation keyword, you can dir

difference between Httpclientpost and Httpclientget is that the HttpPost is to specify the data entity to commit, and the implementation here is like a map, so this is the most convenient way to have more parameters. listExample Public Staticstring loginbyhttpclientpost (string username,string password) {Try{HttpClient Client=Newdefaulthttpclient (); String Path= "Http://192.168.254.100:8080/web/LoginServlet"; HttpPost Post=NewHttpPost (); //specify the data entity to commitlistN
In Android development, we often use the network connection function to interact with the server. Therefore, the Android SDK provides Apache HttpClient to facilitate the use of various Http Services. You can think of HttpClient as a browser. Through its API, we can easily send GET and POST requests (of course, its functions are far more than that)
