How to get JSON data for any website to parse and use in my android native app
<p>My understanding is that as an android developer in order to develop native android apps for existing web applications built using Spring MVC or PHP or Angular JS, I need to access the data in JSON format and use in my android app as per my needs. For this I don't have to know anything about the web frameworks which were used to build the websites.</p>

<ol>
<li><p>Is my understanding correct? If no, please correct my understanding.</p></li>
<li><p>If yes, should I just ask the developer (or) find that info someplace (posted for use) to know how to access the json data for their website and use it in my code? (or) is there something else I need to do? </p></li>
<li><p>If the developer has to provide the info for JSON, what should I specifically ask for? and What will the developer provide me?</p></li>
</ol>

<p>Thanks for your help in advance!</p>
