I am trying to push data from my server hosting a webservice but I get
the following error:
<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">

Here is the java code that posts message to google c2dm which inturn
will send a push notification to the device:
private void postData(String auth, String id, String data) {
DefaultHttpClient client = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"https://android.apis.google.com/c2dm/send";);
List<NameValuePair> formparams = new ArrayList<NameValuePair>();
formparams.add(new BasicNameValuePair("registration_id", id));
formparams.add(new BasicNameValuePair("data.payload", data));
formparams.add(new BasicNameValuePair("collapse_key", "something"));
//formparams.add(new BasicNameValuePair("Content-length",
""+data.length()));
if (null != id) {
formparams.add(new BasicNameValuePair("id", id));
}
UrlEncodedFormEntity entity = null;
try {
entity = new UrlEncodedFormEntity(formparams, "UTF-8");
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
httppost.setEntity(entity);
Header header = new BasicHeader("Authorization: GoogleLogin auth=",
auth);
Header header2 = new BasicHeader("Content-length=",
""+data.length());
httppost.addHeader(header);
httppost.addHeader(header2);
httppost.getParams().setParameter("Content-length:",
""+data.length());
HttpContext localContext = new BasicHttpContext();
HttpResponse response = null;
try {
response = client.execute(httppost, localContext);
HttpEntity entity2 = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
Header[] headers = response.getAllHeaders();
for (int i = 0; i < headers.length; i++) {
System.out.println(headers[i]);
}
System.out.println("----------------------------------------");
if (response.getEntity() != null) {
System.out.println(EntityUtils.toString(response.getEntity()));
}
} catch (Exception e) {
System.err.println(e);
} finally {
}
}
Note:
1. I successfully got the registration id from the client (device)
2. I successfully get the "Auth" from an earlier post on the server
side
Any help will be greatly appreciated
Thank you
