C2DM: Get ClientLogin Authentication Token

To send C2DM messages, you should create a new google account as an app-based sender ID and get the ClientLogin Authentication Token.
The most convenient way is using Curl:

curl https://www.google.com/accounts/ClientLogin -d Email=$1 -d Passwd=$2 -d accountType=GOOGLE -d source=companyName-applicationName-versionID -d service=ac2dm

Replace $1 with your sender google email account address
Replace $2 with your sender google email account password
Replace companyName-applicationName-versionID with something like "Gulp-CalGulp-1.05"

It may take more than 1 minute to get the response. Be patient.
The correct respond is like:

SID and LSID is useless. What we want is the "Auth";


Another option using Java program to get ClientLogin Token:



 HttpClient client = new DefaultHttpClient();
 HttpPost post = new HttpPost(
         "https://www.google.com/accounts/ClientLogin");
 try {
     List nameValuePairs = new ArrayList(1);
     nameValuePairs.add(new BasicNameValuePair("Email", "your_sender_email@gmail.com"));
     nameValuePairs.add(new BasicNameValuePair("Passwd", "your_sender_email_password"));
     nameValuePairs.add(new BasicNameValuePair("accountType", "GOOGLE"));
     nameValuePairs.add(new BasicNameValuePair("source",
             "Company-App-Version"));
     nameValuePairs.add(new BasicNameValuePair("service", "ac2dm"));
     post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
     HttpResponse response = client.execute(post);
     BufferedReader rd = new BufferedReader(new InputStreamReader(
             response.getEntity().getContent()));
     String line = "";
            String auth = "";
     while ((line = rd.readLine()) != null) {
         Log.e("HttpResponse", line);
         if (line.startsWith("Auth=")) {
             auth = line.substring(5);
             Toast.makeText(this, auth, Toast.LENGTH_LONG).show();
         }
     }
 } catch (IOException e) {
     e.printStackTrace();
 }
