My client has Joomla website with plugins (Mosets tree and JSE events) that basically lists business an events. He wants an android app developed to fetch these info. Immidiately what came to mind, is I create php scripts that query the Database and I call those scripts from my app. In my app, I display the information collected.
Another idea that occurred to me, is to enable RSS feed and then I read this RSS feed.
Is my approach above the right approach? Is there a different way or standard way when developing apps that fetch information from the Joomla website backend?
Please note the website is already mobile friendly but the requirement is to create an app for part of the website. Any pointers are helpful
Building one or more PHP scripts that query the db and returns the data is definitely the faster and simpler solution.
If you want to build a more robust / compatible solution, you may extend your set of PHP scripts into a full blown REST API application. In that case take a look frameworks like SLIM or SILEX which are very good at this.
There are more complete and elegant solutions but they are probably overkill for your needs.
Edit: why query directly the database
In theory, it seems to be better to NOT access directly the database, and interact with the Mosets Tree component instead; because in that way you will not have to duplicate any logic.
But in my experience, with a very few exceptions, Joomla components are coded so that it's very hard to interact with them programmatically.
I answered a similar question regarding Joomla RESTful APIs here:
REST API for Joomla 3.0
Basically, I ended up developing a solution which meshes the Slim PHP micro-framework with the Joomla Framework / CMS (requires Joomla 3.4.3+).
Why?
Well, the main reason is that while using the Slim framework would be OK as a one-off solution, I realized that one would still need to develop all the accompanying ACL and access security, not to mention the actual CMS that might store and manage all the important data in the first place.
Basically, I did the work so you don't have to. Yes, it's a commercial component (must pay to download) but I think it's WELL worth it for what you end up getting out of it.
It's brand new, so the service routes in the cAPI ("Constant API") Core package are still limited, but those are being built-out over time (all included in the core package of course). The component/plugin/library package is architected to allow for easy integration of add-on plugins which will introduce new service routes to add functionality like RESTful JSON APIs for MySQL, MSSQL, MongoDB, LDAP, etc. I already use an alpha version of the LDAP add-on in a an enterprise environment, so I expect that to be available for purchase/download soon.
The point of all this is that you can use an existing Joomla site to drive mobile apps (with some development for Mosets), while taking advantage of built-in user management and ACL, along with token auth (via cAPI).
Let me know if you have any questions.

I am an Android developer and I want to make an app which shows users on a map and performs tasks based on their location.
The whole model of the app has to run in the server. I need an API which:
Receives user location
Performs calculations based on the location of the users
Sends response to specific users with the results
The problem is that I have 0 experience in doing server side programming.
Can you please suggest me a way of making the server?
I checked the Google Colud Platform and this video. The video addresses the connection between the app and the server, but what I really need is coding the model and deploying it on the cloud.
What is the way for me to build the API for such an app, as a developer with no server side programming experience?
Can you suggest me a tutorial which goes trough the process of building a cloud backend for a mobile app?
This is a very complex question. I don't recommend using a "ready-made" solution like FireBase because it's even harder to transform it into a "proper" API later on when you need it. If you know Android then you know Java, you'll have no problem learning working with a framework like Spring Framework which I recommend. Java on the backend needs a Java Servlet container, like Tomcat. First you should set up a development environment on your machine for this. I recommend searching for Spring Framework tutorials for this i.e. Spring Framework REST tutorials.
Secondly you'll need a database like MySql or MongoDB to store data. Spring comes with ready made connections to most of the most common databases, so its pretty easy to work with them.
When you're ready to deploy your service I recommend using a PAAS like Heroku.com where you can run your service for free first. In this way you get to control everything yourself and you also learn a useful skill.
Since you are coming from the JAVA background you just need some basic building blocks and you shall be good to go.
Use PASS: They will take any devops from your side which will be a big relief considering you are not familiar with anything on server side. I recommend using Heroku or App Engine. Here's guide to App Engine with JAVA on top. https://cloud.google.com/appengine/docs/java/
Database: Not sure how you are storing and managing your user data as of now, but if you need database, there are various of those available now. The reason Firebase is top suggestion, cause it leverages realtime and gives you control on your side without spending a lot of time on your side.
APIs: You will be taking user's geo-location and sending it to server. On server you will need to process that into a real world location and any other logic. You will need to use Google's GeoLocation and reverse geocoding APIs for that. Find apis here : https://console.cloud.google.com/apis/
Also if it's any help, App Engine and Heroku both offer free limits and should be pretty sufficient for your use case.
Since you have limited experience on server side development I'd suggest using a backend-as-a-service platform. This approach has the benefits of allowing you to focus your time coding the client where your competitive differentiators are, and lets you leverage years of experience in server-side development without having to ramp up on the technology. It also means you can iterate quickly and test features ideas with less risk.
There are several options out there, but in your case, you'll need something that provides enough flexibility to implement custom logic and a custom data model. Some platforms allow you to create a full backend application with REST api endpoints, and automatically take care of deployment, security and management. Some examples of backend service providers can be found here https://en.wikipedia.org/wiki/Mobile_backend_as_a_service.
Some of the platforms actually allow you to build a full custom app without actually writing any code, and some of them provide ready-made components (like chat, leaderboards etc) but are less flexible.
Here's a list of Backend-as-a-service providers:
https://quickblox.com/
https://www.appcelerator.com/
http://www.configure.it/
https://cloudboost.io/
http://api.shephertz.com/
https://backendless.com/
http://pipegears.com (No coding required)
You didn't provide specific details about the tasks you want to implement on the backend, but it's likely that you could satisfy your requirements with a straightforward REST api that accepts your location data, runs business logic, reads or writes from your data model and returns whatever data your client needs. (Sorry I can't get more specific without details on your requirements). If you're dealing in sensitive information like location data, I'd strongly recommend securing the api with TLS/SSL (i.e. https), or make sure the platform you use provides this.
Can someone give me a broad overview of what pieces would have to be in place to implement a user-content-driven Android app with a web-based database? Or, link me to some helpful relevant articles on web and app architecture to study?
Further, if II already have a website where people can add content and others can vote on it, and I want to have the same capabilities available via an app, utilizing the same central database, how would I proceed?
I'm guessing I could provide remote authentication into the site via the Android app, and then enable the user's content submissions and votes to sync with the database (and website), but how is that handshake process done? And what elements of the site have to be exposed for the app to "connect to"?
Where are lines drawn between a website just being presented inside an Android web view and being made mobile friendly, versus a stand-alone app having the web/database functionality?
I know if I already have a mobile-friendly website, it might seem logical to simply direct people to the mobile site, but obviously a lot of people use apps and there are some benefits over mobile web.
Sorry for such a general question, but I can't seem to find any good examples of people doing this to learn from, even though I imagine it must be very common.
Thanks!
The best practice is to build REST API on server side to manage content from database, and just hook to it with mobile apps. There is a lot of different libraries to do that on both Android/iOS
create your rest api and make it return json.
i think that the better way is to use okhttp http://square.github.io/okhttp/
for http connection,
retrofit and gson http://square.github.io/retrofit/
for parsing json results;
I'm building a new application for android and this would need to send and retreve data from an online database.
Firstly is this possible or is it a completely wrong approach?
Would i be able to tell my application to set certain data into the server and retreve other?
Does it create security risks by which anyone would be able to access the database?
It's my first time dealing with anything close to databases so i'm still learning.
Is there any website i can use which sets up an accessible SQL database?
Thanks for your help!
The Good approach for this is that you should create REST (Representational State Transfer) API on server and perform CRUD operations in your Android app using that API.
There are a lot of security problems with embedding direct database access into your app.
Usually,REST architecture is very useful to build client/server network applications. REST basically works on HTTP protocol and implementing REST is very simple compared to other methods like WSDL etc.
There are many good tutorials available on implementation of REST API that you can easily find by Googling it.
Here's one of them: http://www.androidhive.info/2014/01/how-to-create-rest-api-for-android-app-using-php-slim-and-mysql-day-12-2/
Yes, it is possible and it is not the wrong approach. Web services/REST API's are some things you should look at.
There are obvious security risks associated with having an outward facing web service or database. OWASP has a pretty good
web services guide that should get you started with the
security. You will need to address these risks prior to holding any sensitive/user information. There are plenty of guides online.
A couple of database hosting suggestions Amazon Web Services if you want it to be manage dfor you or create a VPS at Digital Ocean (or similar) website if you want to do it yourself.
Due to the open ended nature of this question there are numerous ways you can address these problems. I recommend spending a lot of time researching and analyzing them prior to starting the project and deciding on a technology.
This is not a wrong approach, most of the Android application send or receive data from online databases.
For connecting your Android app with the online database you can make of webservices , for instance you can create Rest Api for this.
For creating Rest Api using Asp.net web api visit this link
The answer for your last question would depend on the way your write your web services decide the security risk.

I want to develop a application where part of the data is dynamic like picture , show timing etc.Their are many content management system that use HTML5 and CSS but i want to also use the native iOS or Android Ui like the UISplitView for iPad.How is this possible ? whats the best way to manage and use dynamic data ?
I have been digging into this very exact answer. The best answer I can come up with is called parse.com. Which may not be 100% of what you are looking for. However. What it does is serve as a central database that talks to multiple platforms(windows 8, iOS, Android) and offers up an api for use with every platform with lots of documentation to make programming super easy. http://deployd.com/ also This site is something Ill be looking into which uses a simplified node.js desktop for programming easy objective based functions with a database. Definitely am still looking. Either way the bast thing is to call your view...bring in a few objects...and have these databases feed your objects to specifically answer your question.
As a developer Im used to Joomla and magento. These arent necessarily ios friendly. Anyway, best of luck.
I'd suggest taking a look at Cloud CMS (http://www.cloudcms.com).
Cloud CMS is a cloud content management system that is built around JSON schema. Unlike traditional web content systems, Cloud CMS works with JSON and binary files (either through MongoDB GridFS or Amazon S3). It provides full-text search, structured query and an entire suite of enterprise features for things like workflow, analytics, users and groups and more.
From an iOS or Android viewpoint, you really only need to interact with the REST API. You can do that directly or use one of the client libraries.
Disclaimer: I'm one of the founders of the company. Would love to find out what you think and learn what we can do to improve things. We're having a great time reinventing CMS for mobile.
This is my website: http://www.stustu.co.uk..
I want to create an app that can pull down the listings from this website and display the entries in the form I want; enable users to manage their online accounts conveniently within the app; post new entries. Basically, a similar app to Amazon and eBay.
But I've no clue about how to query the information from the website in the app...
The website itself is WordPress based (quite simple, therefore), and my initial thought was to find some API from WordPress. I did find the official WordPress app, which comes with the source code, but it helps little as its code mainly deals with blogging.
So here's my question:
What are the normal ways a web developer would use on the server side to achieve my aim?
Is that achievable for WordPress?
If not, are there workarounds?
I'm a new self-taught developer, sorry that the question is a bit broad.
The most common approach when you're trying to communicate between an app and a website is to use a web service. Popular architectures include using REST or SOAP to communicate with your server.
This video will teach you how to use REST interface properly on your Android application, while in this link you will find that using SOAP has its disadvantages over REST especially on Android(or mobile in general).
I personally recommend using REST APIs with responses in JSON format for your web service. Twitter did the right thing with their own rest api, and you can structure yours similarly.
Other links you will be finding useful as you develop your application:
google-gson
jackson JSON
http://blogs.developerforce.com/developer-relations/2011/02/rest-api-android-awesome.html
Sorry about not answering your question about Wordpress, as I never had the opportunity to use it. For my apology, have this potato.
How much experience do you have with android? If you have none you should go find the getting started tutorials on the developer site and complete a few of them to familiarize your self with the structure of an android application before you attempt something like this.
The next thing to consider is: does your site look and act nicely on mobile? If so do you want your application to simply be a dedicated browser that pulls up your site? Or do you want to create the entire application natively? In the latter case you'll have to build (or find) some sort of APIs that allow you to tie in to the functionality of your site from within the java in the application.
My experience is mostly on Android so I cannot suggest any strategies or examples for how you'd go about setting up your APIs. But I do know if you attempt to build something that sophisticated natively on android with little experience you'll likely get frustrated early.
