How to connect to Google calendar API through android

[Appugouda]

I want to access the Google calendar APIs in my android application. I am trying to write aa application similar to Google Calendar. I was unable to connect through the Google Calendar APIs , So I tried by writing a simple Server side program (using servlet) where I was trying to connect to the Google Calendar API. I am sending the parameters ( Email ,Passwd,Source,service) through normal jsp, which are required to login to the Goolge account. I am trying to send these data to this link : https://www.google.com/accounts/ClientLogin. In my Servlet (LoginServlet) I am trying to connect to the above link. I am unable to connect to the link. I I send the same data to another servlet then I can send the values.
