android and server
<p>im really new to this so dont spare any answer even if its really basic..</p>

<p>i want to make an android app that sends a number to a server, and i want the server to check its data base if any other users entered the same number. I want the server to reply which number has the same number. </p>

<p>i also want the server to send the other users that holds this number a messege about a new user that hold this number.</p>

<p>i hoped i made myself clear.</p>

<p>i have no idea where to start... how to write the server side (language/where do i get a free server)?</p>

<p>thanks</p>
