我如何发送的GPS和网络定位cordinates到服务器（静态IP）？ [英] How can I send the GPS and Network location cordinates to a server (static IP)?
问题描述
我在Android Development.I初学者想打一个Android应用程序，它发送的GPS和网络位置（经纬度和放大器;长）到我的服务器（静态IP）。 我发现下面的code和它成功的工作，数据接收，在其已经在服务器端所做的应用程序（目前它无关，与客户端应用程序）
在我的服务器接收的数据，当我点击按钮发送位置在我的Android应用程序。
-
GET /31.4244456/74.7349772 HTTP / 1.1
-
主持人：180.178.169.77:6081
-
连接：保持活动
-
用户代理：Apache的HttpClient的/不可用（Java 1.4中）
180.178.169.77是我的服务器IP和6081是端口
在这一点上一切都很好，我来达到的，几乎是我想要的，但我现在面临的真正问题是，我的Android应用程序挂起和崩溃发送该数据到服务器后。请解决我的问题，如果任何人有一个想法。
我已经找到了code从这里开始。 <一href="http://www.gideondsouza.com/blog/how-to-get-the-current-location-address-and-send-it-to-a-server-on-android#.UNLbTOT0Dxo" rel="nofollow">http://www.gideondsouza.com/blog/how-to-get-the-current-location-address-and-send-it-to-a-server-on-android#.UNLbTOT0Dxo

I am a beginner in the Android Development.I want to make an android app which sends the GPS and network locations (lat & long) to my server (static IP). I have found the following code and it worked successfully, data receive at the app which is already made at server side (Right now it has nothing to do with client app)
Data received at my Server when I click the button 'Send Location' on my Android App.
GET /31.4244456/74.7349772 HTTP/1.1
Host: 180.178.169.77:6081
Connection: keep-Alive
User-Agent: Apache-HttpClient/Unavailable (java 1.4)
180.178.169.77 is my server IP and 6081 is the port
At this point everything is going fine and I acheived almost what I wanted but the real problem I'm facing is that my Android app hangs and crash after sending this data to server. Please resolve my problem if anybody has an idea.
I have found the Code from here. http://www.gideondsouza.com/blog/how-to-get-the-current-location-address-and-send-it-to-a-server-on-android#.UNLbTOT0Dxo

Move postData off the main thread to a secondary thread. Look at Async task for examples here: http://developer.android.com/reference/android/os/AsyncTask.html
