You can log messages by using <code>Log.d("tag", "msg");</code>

You can also use <code>Log.i("tag", "message"), Log.warn("tag", "message")</code>

You need to use a <a href="http://en.wikipedia.org/wiki/Proxy_server" rel="nofollow">proxy server</a> (a program that runs an HTTP server on some port, but instead of having Web pages of its own, it then goes and loads pages from another server). The choice of whether to use an existing server or to write a complete one (maybe in Ruby) depends on what you mean by "modifying" the requests and responses.

I can think of a number of possibilities:

<ul>
<li>If you simply want to see what is sent to the server, then you could use a packet monitor / sniffer such as Wireshark. This is probably the simplest approach ... if it does what you want.
<a href="http://blogs.technet.com/b/yongrhee/archive/2012/12/01/network-tracing-packet-sniffing-built-in-to-windows-server-2008-r2-and-windows-server-2012.aspx" rel="nofollow noreferrer">http://blogs.technet.com/b/yongrhee/archive/2012/12/01/network-tracing-packet-sniffing-built-in-to-windows-server-2008-r2-and-windows-server-2012.aspx</a></li>
<li>If you want to intercept and (potentially) modify the request, then you could use a web proxy service. (The snag is that you need to configure your client to send requests destined for the server via that proxy.)</li>
<li>In theory, if you are running on a system that uses packet filtering, you could route the TCP/IP stream through a local "service" that captured and maybe even rewrote the data.</li>
</ul>

sorry for a newbie question, but..

when I send the REST request to a localhost via http is there any chance
to check what exactly this request consist of/ modify it before it reaches server.

No debugging is available. 

if it was just web-client i'd simply use fiddler or somethings, what is the way to see the requests coming to a certain host from a mobile device?

UPDATE: currently ... I just need to see what is the format of JSON is coming out of application

Analyze http rest request before in reaches server

很抱歉有个新手的问题，但是..。当我通过http将REST请求发送到本地主机时，是否有机会在到达服务器之前检查该请求包含/修改它的确切内容。没有调试可用。如果只是网络客户端，我会简单地使用小提琴或其他东西，有什么方法可以看到从移动设备到某个主机的请求呢？更新：目前.我只需要看看应用程序的JSON格式是什么
