Do not use Cloud to Device Messaging, instead use the latest cloud approach with andrid application development.

There is new library called Volley, which looks better than AsyncTask. It should be useful in developing RESTful clients.

Answer 2

You probably forgot to add the internet permission to the manifest file. Add the following line.

 <uses-permission android:name="android.permission.INTERNET" />

Answer 3

By any chance, is the server expecting a GET request for this operation? If so, you may want to use HttpGet instead of HttpPost.

Answer 4

I thing you should try this,

HttpContext localContext = new BasicHttpContext();
HttpClient client = new DefaultHttpClient();  
HttpPost post = new HttpPost("REST API url"); 
post.setHeader("Content-type", "application/json");

JSONObject obj = new JSONObject();
obj.put("username", "un");
obj.put("pwd", "password");
obj.put("key","123456");

post.setEntity(new StringEntity(obj.toString(), "UTF-8"));
HttpResponse response = client.execute(post,localContext);

Hope this will help.
