title: How to send multiple parameters from android app to search in database?
body: <p>I am creating simple search application. I have search parameters in ArrayList that I want to use to make search in database. Every single time size of ArrayList would be different. I already have most of my application completed and this part made me completely stop. </p>
  
  <p>I use Volley and my PHP for getting JSON from database and I read that I could also send parameters by Volley, but don't think it would work for me.</p>
  
  <p>Friend told me that only way to make this is to use services (I still trying to understand what they are). I tried researching Django, Spring, but I cant understand what I can use them for, I'm so confused about this part.</p>
  
  <p>I want to ask for your guidance for my specific problem, because I don't even know what I should be paying my attention searching in Google as there not so much tutorials for Spting framework or Django or other methods.</p>
