android share app data between the users
<p>I am developing an app in which, in a particular activity there are some articles on which users are supposed to discuss, i.e. post their comments.
So, if anybody comments on a particular article, that comment should be visible to all the users on their cell,who are subscribed to that article.</p>

<p>Now, I am not able to figure out how to carry out this.
I have referred to the developer's site <a href="http://developer.android.com/guide/topics/data/index.html" rel="nofollow">http://developer.android.com/guide/topics/data/index.html</a> and some SO's questions also but still no ans.</p>

<p>Please help..</p>
