Best practice for android web app
I'm new to android app development and I'm not sure that I'm approaching my problem correctly:

I want to develop an app that displays some info from a specific website, so for example I want to display all links that are contained in a :

    <div class="title"> link </div>
For this I want to develop a parser in java which will search for the `<div class="title">` in the page source.

Now my question is: Is it a good practice to store the search string :`<div class="title">` in a file on a server and each time the application loads it will download this string?
If the `<div class="title">` for example changes to `<div class="abc">` I want to change the string easily and not make the user to download an update for the app.

Is there a better approach on the problem than the one i thought of?
