I'm wondering the easiest way to go about this. I've used retro fit for java before to post and get from endpoints in web service my friend wrote in python.. However I've never wrote server side stuff. I have phpmyadmin running on a vitural server... Havnt used it yet however. I just need people to be able to like or dislike a poem on my database. I know how to create the database... What is the best way for me to do this? I've looked this up on Google with so many results but not sure where to start!
Found out the easiest way to go about a restful service. Google app engine! You can easily create endpoints and add objects like a breeze!

I want to create an app for a website that I don't own, like youtube or reddit. Every time I search for help, all I keep getting is how to create a webview. I've done that but that's not what I want. I want to take the website's content and create an app with it, like create my own buttons and such. I want to convert a website into an app.
I was thinking of somehow loading the website in the background and creating activities/buttons/intents that basically do what the webpage does but I don't know how to go about that or if there's a better way.
Thank you in advance.
Please let me know if clarification is needed.
Alright i got -3 votes for some reason and it has been 12 hours since i posted this question, i'm guessing the question has been consumed by the abyss of questions by now.
I made a reddit post and got some responses:
one user:
The term you’re looking for is “web scraping“ or “site scraping”. I think that’s probably what you need to research before you’re ready to handle how to make that into an app.
That’s a good starting point and once you have the content from scraping, making the app is no different than any other app.
second user:
If the website has a public (or private) API, you can use your buttons and networking calls to their API to build your client app. You are building a "YouTube client" in this case using the YouTube API.
If they dont have an API and you don't want to display their website, what you are doing is trying to reverse engineer their website and hijack the UI which is not a good practice and may even be illegal depending on the site and terms.
third user:
#second user is right on the money, but one thing I'll like to add is, the goal is to get data off of the website so that you can use in your app. An API is one (convenient) way of doing that but others are,
RSS or similar feed content (prefer this if there website supports)
HTML scraping
The above two will require you store the data somewhere else (and possible expose an API instead) because of technical reasons: you don't have access to older entries in RSS feeds and it's atrocious to keep on scraping everytime you need to access the website data. They can be done on the client (mobile app) but are best done on a server. This means you might need to get your hands dirty writing server code but you don't have to.

I'm going to do research on website scrapping and APIs to see which route i should go.
Hopefully this helped someone else.
I'm having a small problem with a personal project, I'm trying to create an auction site in React - it's an amazing learning experience - with a Java backend.
One trouble I've stumbled upon is how to "sync" data effectively, when new data is inserted into the database from a different user, such as if a user would bid on an item, how would other users update their data?
The only way I can see it happening is with a push model, or constantly polling for data from the server. Both seem pretty out of reach, to be honest, although the push-model seems the more likely of the two.
I could somehow set up an observer pattern with users "registered" when viewing an item, although if there is a better method, I would love to hear it.
I already tried searching for answers, but either none exist (I doubt it), or I'm simply terrible at using Google and don't know the keywords to search for to get the specific results I need. (Likely)
Thanks in advance!
You are looking for a kind of server push technology. Try researching more into Websockets or Server-Sent-Events.
A start could be: WebSockets vs. Server-Sent events/EventSource
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.
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.
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.
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.
I want to create a java server application which receives data from an Android client and also transmit notification to client. Actually i did not know much about server apps. I am quite familiar with servlets and mysql, is there any tutorials based on these??
So any suggestion how to build it or any tutorials for it?? please help me!
What you are probably looking for is Google App Engine a SaaS by Google. While there are many alternatives this is probably the best route you can take for implementing a Java based backend. Follow these tutorials* and you'll be good to go. Keep in mind the GAE is a bit complicated and will take some time to get on your feet.

More tutorials on GAE can be found by a nice google search!
Now, I have some problems here:
I looked several times in Google and so on, but I can't find an "easy" way to get this done. And currently having a migraine... not helping me... though
I have a java eclipse program (Swing application to be a "controller" for production-machines).
I need to design an Android app, which needs to take data from the eclipse program in a wireless network (and also send them back).
Just found solutions like JPARSON or setting up a real server, but that is way too complicated... i don´t need?! (or want :D ) to set up a whole website with php or something...
Can someone of you help me out with a better solution? It doesn't need to be code-specific, I just want to exchange like 10 strings for these machines.
If you want to exchange data you need a communication medium. The easiest way to do this is via TCP/IP protocol suite. If you decide on having a Server-Client architecture, your serwer has to listen for what phones have to say. He can do this by listening on specified port and you would have to handle "protocol", or you can use somewhat easier approach which is to write php script, or Java Servlet. PHP script is easier becaouse there is like a gazzilion php hosting providers and it's cheap. If you would like to write your own serwer, you wold need some sort of Virtual Private Server, and deploy your app there. Plus it would be helpfull if you explained a little more your environment and what you are trying to achive.
There's built in httpserver http://docs.oracle.com/javase/6/docs/jre/api/net/httpserver/spec/index.html so you can easily implement a simple webservice in standalone java. Then just use URLConnection from android to post/get data, probably in json or your own format.
