Android app update after server change
<p>I'm new on android developping and I want to create an small app whitch parse my php file from my server.</p>

<p>I can parse a php file, but if php file change my apps doesn't update - I must close app and reopen. What is best way to check if php file is updated and show updated file? </p>

<p>Or insert timer in app? But I think this is not best way to insert timer every  1 seconds to check php file and update app screen. Maybe everyone know where find tutorial or something?</p>
