I was missing proxy credentials in my code... i then added them :

HttpHost proxy = new HttpHost("myproxyurl, "http");
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);

it solved "org.apache.http.conn.HttpHostConnectException: Connection
tohttps://android.apis.google.comrefused" exception.

No i get following error :

Try Adding these permission in AndroidManifest.xml

<!-- Only this application can receive the messages and registration result -->
    <permission android:name="com.example.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" />
    <uses-permission android:name="com.example.myapp.permission.C2D_MESSAGE" />
   
    <!-- This app has permission to register and receive message -->
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
   
    <!-- Send the registration id to the server -->
    <uses-permission android:name="android.permission.INTERNET" />


Hope This Works!!!

hi D,

what account are you using to authenticate your requests to the C2DM
server? you need to use the role account (not a personal/user account
used on one of your target devices) specified when you signed up for
the C2DM service.

thx, debajit

[D KYON]

Hi Debajit,

Am using the account which i specify when I sign up for the C2DM
service.
And I aslo tried getting the authToken from my app server

The code is as given below :
----------------------------------------------------------------------------
public static void performAuthentication(String regId)
{
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
System.out.println("Performing Authentication ");


// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://www.google.com/accounts/
ClientLogin");

HttpHost proxy = new HttpHost("myproxyurl", 80, "http");
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);

HttpParams params = httpclient.getParams();
params.setParameter("content-type", "application/x-www-form-
urlencoded");
try {

// Add your data
List<NameValuePair> nameValuePairs = new
ArrayList<NameValuePair>(2);
nameValuePairs.add(new
BasicNameValuePair("accountType","HOSTED_OR_GOOGLE"));
nameValuePairs.add(new BasicNameValuePair("Email",
"x...@gmail.com"));
nameValuePairs.add(new BasicNameValuePair("Passwd","abc"));
nameValuePairs.add(new BasicNameValuePair("service", "ac2dm"));
nameValuePairs.add(new BasicNameValuePair("source", "MyAapp"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
System.out.println("Execute HTTP Post Request");
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");

HttpResponse response = httpclient.execute(httppost);
System.out.println(response.getEntity().toString());
BufferedReader in = new BufferedReader(new
InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
//String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null)
{
sb.append(line);
}
in.close();
String result = sb.toString();
// System.out.println("Result=" + result);

String authToken=result.substring(result.indexOf("Auth=")+5);
// System.out.println("Token=" + authToken);

System.out.println("Result=="+result);
System.out.println("Token="+authToken);
System.out.println("SendingId="+regId);
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");

sendMessage(regId, authToken);

} catch (ClientProtocolException e) {

// TODO Auto-generated catch block

} catch (IOException e) {

// TODO Auto-generated catch block
}


}

Am getting the authToken from google i.e https://www.google.com/accounts/ClientLogin.
and passing the same to the below given method.

public static void sendMessage(String regId, String authToken)
{
System.out.println("Sending Message");
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost("https://android.apis.google.com/
c2dm/send");

HttpHost proxy = new HttpHost("myproxyurl", 80, "http");
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);

HttpParams params = httpclient.getParams();
params.setParameter("content-type", "application/x-www-form-
urlencoded");

httppost.addHeader("Authorization: GoogleLogin auth=", authToken);


try
{
// Add your data
List<NameValuePair> nameValuePairs = new
ArrayList<NameValuePair>(2);
//nameValuePairs.add(new BasicNameValuePair("Authorization:
GoogleLogin auth=", authToken));
nameValuePairs.add(new BasicNameValuePair("registration_id",
regId));
nameValuePairs.add(new BasicNameValuePair("collapse_key", "TEST"));

// nameValuePairs.add(new
BasicNameValuePair("data.<key>","FirstNote.<First>"));

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request
System.out.println("Executing sendMessage");
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
HttpResponse response = httpclient.execute(httppost);

BufferedReader in = new BufferedReader(new
InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null)
{
sb.append(line + NL);
}
in.close();
String result = sb.toString();
System.out.println("Final Result=" + result);

} catch (ClientProtocolException e) {

// TODO Auto-generated catch block

} catch (IOException e) {

// TODO Auto-generated catch block
}

//sendOther(authToken);

}

Still i get 401 Unauthorized exception.

One thing i wanted to know is is there any error in my HttpPost
implementation (in 3rd party app) or in registration process of my
android application.

Thank you

Hi Roshan,

I Dint use any servlet my requirement was different... from a
webservice i just make call to a static method


Code : -

Below given code is to get the Auth_token for ur 3rd party app server

public static void performAuthentication(String regId)
{

regId = "ur_app_registration_id";

// Create a new HttpClient and Post Header

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://www.google.com/accounts/
ClientLogin");

// this is for proxy settings
HttpHost proxy = new HttpHost("ur_proxy_server_url", 80, "http");

httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);

HttpParams params = httpclient.getParams();
params.setParameter("content-type", "application/x-www-form-
urlencoded");
try {

// Add your data
List<NameValuePair> nameValuePairs = new
ArrayList<NameValuePair>(2);
nameValuePairs.add(new
BasicNameValuePair("accountType","HOSTED_OR_GOOGLE"));
nameValuePairs.add(new BasicNameValuePair("Email",

"ur_registered_email_id"));
nameValuePairs.add(new BasicNameValuePair("Passwd","*******"));

nameValuePairs.add(new BasicNameValuePair("service", "ac2dm"));

nameValuePairs.add(new BasicNameValuePair("source", "sourcename"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

logger.info(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
logger.info("Execute HTTP Post Request");
logger.info(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
// Execute HTTP Post Requestu
HttpResponse response = httpclient.execute(httppost);
logger.info(response.getEntity().toString());

//sendMessage(regId, authToken.trim());

} catch (ClientProtocolException e) {

Following code is to send the message to C2DM server :

[D KYON]

Hi Roshan,

Android will call my webservices for registering the application with the server by passing the registrationId .. later it calls another webservices method to notify android.. the webservices method inturn call the c2dm for sending the notification message to android

[roshan vidapanakal]

Hi D KYON,
What is the role account and the contact email while signing up for
c2dm

i am the application developer, i will get auth token for my email
account on the server side

if the other people wants to use my app (which as c2dm service) they
need to register and send the registration id to the server, then with
my auth token i'll send messages to that user.

is it correct.

does the user who wants to use my service needs to again sign up for
c2dm or only register.

if any one resolved this problem plz address here. i am in urgent need
of this.

--
Regards,
Roshan

[anil kukreti]

The android user just has to register with the already verified c2dm account.
