httpconnection

is it possible to use range header in HTTP with HTTP GET request? if yes than how? I just want to download bytes from server with specified bytes. i.e if I want to download bytes from 0 to 255. See this sample code, HttpConnection connection = null; InputStream inputstream = null; try { connection = (HttpConnection) Connector.open(url); // Enter your URL here. //HTTP Request connection.setRequestMethod(HttpConnection.GET); connection.setRequestProperty("Content-Type","//text plain"); connection.setRequestProperty("Connection", "close"); // HTTP Response System.out.println("Status Line Code: "

I just noticed a strange thing in MIDP 2.0 API: The HttpConnection class apidocs make explicit references to methods GET, POST and HEAD, but no other methods. Does this mean that they are not supported? http://java.sun.com/javame/reference/apis/jsr118/javax/microedition/io/HttpConnection.html I also tried checking the MIDP 2.0 spec, but couldn't find any hard facts about this. I can give this a try on some phone(s), but can't try them all. Does anyone know which HTTP methods are required to be supported by phones implementing the MIDP 2.0 spec? Or any experience in finding phones that support

I have a HTTP server in Android. I create a new thread for each of the HTTP requests as in the link mentioned: http://hc.apache.org/httpcomponents-core-ga/httpcore/examples/org/apache/http/examples/ElementalHttpServer.java . When I issue multiple GET requests, sometimes I am getting an exception like the following: 01-22 10:28:22.779: W/System.err(2019): java.net.SocketException: recvfrom failed: ECONNRESET (Connection reset by peer) 01-22 10:28:22.779: W/System.err(2019): at libcore.io.IoBridge.maybeThrowAfterRecvfrom(IoBridge.java:552) 01-22 10:28:22.779: W/System.err(2019): at libcore.io

当我们开发企业级应用的时候，一般都会选择使用已经封装好的http框架。开源的比较流行的有： 1、volley 2、 android-async-http 3、 retrofit 4、 okhttp 5、 androidquery 6、 AndroidAsync 等。他们各有优劣，不同的框架有不同的效率，在使用的时候可以因地制宜地测试，根据效果来选择使用哪个，之前个人则比较喜欢用android-async- http,。如今Google推出了官方的针对Android平台上的网络通信库volley，能使网络通信更快，更简单，更健壮，Volley在提供了高性能网络通讯功能的同时，对网络图片加载也提供了良好的支持，完全可以满足简单REST客户端的需求, 我们没有理由不跟上时代的潮流。另外，但volley的扩展性很强，可以根据需要定制你自己的网络请求。所以，最后推荐还是使用volley进行开发，当然其他几个库也是非常具有学习以及参考意义的，可以将他们的精髓之处汲取到volley框架的拓展开发之中，做出自己理想的http通讯框架。 推荐博客： http://instructure.github.io/blog/2013/12/09/volley-vs-retrofit/ http://blog.csdn.net/t12x3456/article/details/9221611 http:/

I've got this piece of code http://pastebin.com/VrMNuxcv which successfully uploads a file onto the server from my android. I'd like to , however to be able to send a couple of string parameters together with it. Could you please tell me, if possible, where exactly I need to do this in that piece of code and how? Thanks Andreas I assume that you're in control of how the server processes the upload, i.e., you wrote the server code too??? If so, I simply use custom/private request properties (i.e., prefixed x-) for some client/server code I've written. Example... conn.setRequestProperty("x-myapp

I get the following complete error message: Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 2. Wait queue head age: 9379.7ms.) See below the code + traces. It seems that the lock happens at GetIP_WAN.java:32 which is the line: BufferedReader br = new BufferedReader( new InputStreamReader(conn.getInputStream())); I call this function whenever I detect a network change wifi-3g/4g-no internet. and in a few other places. it happens on every occasion

Volley library doesn't return whole response data. It only return the part of the response data. I am calling drupal services. Below is my code for it. public void BoardRoomRequest() { pdialog = new ProgressDialog(BoardRoom.this); pdialog.setTitle("Please wait...."); String url = Global_Application.url + "views/boardroom"; Log.d("url========", url); Map<String, String> params = new HashMap<String, String>(); StringRequest req = new StringRequest(Request.Method.GET, getApplicationContext(), url, params, new Response.Listener<String>() { @Override public void onResponse(String response) { //

Apache HTTPClient contains SchemeRegistry class (org.apache.http.conn.scheme.SchemeRegistry) What is Scheme Registry? When can it be used? What impact does it make if i use scheme registry like below SchemeRegistry registry = new SchemeRegistry(); registry.register(new Scheme(WEBSERVICE_URI_SCHEME, 80 ,PlainSocketFactory.getSocketFactory())); PoolingClientConnectionManager wsConnManager = new PoolingClientConnectionManager (registry); What is Scheme Registry? Protocol scheme registry maintains a map of connection socket factories per distinct protocol scheme. For instance, HTTPS scheme
