title: Store data in App Engine datastore from an Android app
body: <p>I have created an AppEngine connected Android application, and I'm trying to modify it to be able to store some user data on the server. I do not know what's the easiest way to do so, because I want it to be as simple as possible. I just want to store some basic data for every user. This data is: Name, Email, and some other Strings. I have created a form in the android side which will allow the user to type all the requested data, but I do not know how to send this information to the GAE server and store it in the datastore. I guess I will have to use a Servlet and some kind of RPC service to call the methods. I'm really lost because it is my first time doing this. I'm not experienced neither in android nor in web apps. I hope you can help me.</p>

  <p>Well, maybe I did not explain myself well. The system I've been asked to build consists on a web service that store your personal login credentials for most common sites (facebook, gmail, etc). Using a chrome extension, you ask the server for the credentials on the website you are navigating, and then the server asks to your phone for authorization. It will ask (do you give me permission to send your credentials to "some user"), and you have to ansewer yes or no and then the server will act in consequence. The point is that you have to store your credentials in the server in some way, maybe from the android app (which is what I was trying) or from somewhere else. I will also need authentication.</p>
  
  <p>Pd: I use java for the server side.</p>
