I am having the same problem as you and I think it's not my mistake I
have checked the tcpdump (to do it I changed from https to http to
have plain text).
POST /c2dm/send HTTP/1.1
Authorization: GoogleLogin

This is my code:
Protocol myhttps = new Protocol("https", new
EasySSLProtocolSocketFactory(), 443);
HttpClient httpclient = new HttpClient();
httpclient.getHostConfiguration().setHost("android.apis.google.com",
443, myhttps);
PostMethod httppost = new PostMethod(C2DM_URL);
try {
httppost.addRequestHeader("Authorization", "GoogleLogin
auth=" +
authToken);
httppost.addRequestHeader("Content-Type",
"application/x-www-form-
urlencoded");
httppost.addParameter("registration_id",
registrationID);
httppost.addParameter("collapse_key", collapseKey);
httppost.addParameter("data.receiver", destination);
httppost.addParameter("data.source", source);
httppost.addParameter("data.message", message);
httppost.addRequestHeader("Content-Length",
""+httppost.getRequestEntity().getContentLength());
httpclient.executeMethod(httppost);
return new String(httppost.getResponseBody());
} finally {
httppost.releaseConnection();
}
}
I have tested all those headers and it does not work.
Did you find anything? Is it possible to contact to some at C2DM
project to see what happens?
Thanks a lot!
