I would like to create a local multiplayer server.
My idea would be like this.
Server phone starts a server and any other device calls the server over wifi and see a html5 app. So the client devices doesn't need to download the app.
Are there any good frameworks which supports such a behavior?
I found already i-jetty (https://code.google.com/p/i-jetty/wiki/ConsoleWebApplication), but according to the wiki i need to download the app before. Another thing is I dont know how to access a database over calls to the webserver.
This is a big topic you are asking. A good starting point would be to investigate web services to get your database via a web server.
I'd recommend looking at Web Services..this is a very basic link:

I've got an audio playback application. I need to add a streaming feature which works in coordination with a website. Meaning, when a new file is added to the server and playable via the website, it should automatically become playable on the app. I do not want to hard code it into the app and am looking at making it dynamic. The only solution I can think of is linking the entries to a SQL database, however, the web developer has expressed security concern. He thinks allowing applications to connect to the db could pose a risk.
Any ideas on implementing this?
I have been to similar situation many times. A web Socket is the ideal solution for such cases.
And the mobile should never connect to the db directly. the connection should be done , validated and monitored through a web service providing the Mobile with a RESTful Api.
I want to create a web server at home and upgrade it to communicate with my Android app. Eventually I would like to store SQL data on it and collect data from it in my Android app. I have no idea where to start, and I am worried that I might start with one tutorial which will eventually not be able to give me the end result I want.(I am looking for tutorials at the moment since I have no knowledge on server side coding or anything similar)
So I was wondering if XAMPP is the thing I am looking for? I found many tutorials on that but I can't find anywhere if it is possible to eventually store my SQL data and communicate with android app. Also I read that XAMPP is for testing purposes and I would like to start learning something I might actually use as a web server later on for commercial apps.
If not, what else can I use? Many websites suggest JSON server communication but I am still not sure if that is the thing I am looking for.
Install xamp on your pc
Create the php file to communicate with the android data
Use http://10.0.2.2:80/ as a server ip in your android project

I am trying to create an android application in which an user will pretty save some data in database-like user data, photos and also be able to retrieve.
But I am clueless how to set up a server, connect to some database etc.
Can somebody help me point to right resources for end-to-end installation of server, database, and its interaction with the android application
Just set up a basic server that works over HTTP, and use HTTP libraries for android to make requests and handle results in the device. There are plenty of technologies with which you could make the server, just google building REST API with PHP/.net/java (whichever language you are comfortable with).
If you are mobile app developer and want to create server-client app then better use any back-end service rather than implementing new by own. Some most advanced and simple to use services are Parse and Firebase , BaasBox also there are many more.
And the plus point is this services free of cost until you have very large users.
I am new to mobile applications. I am basically from a web development platform. I am just playing around mobile frameworks like App Framework, LungoJS, Jquery Mobile, kendo etc to gain some knowledge in this vertical.
The app I am developing is still in UI level. All I need is to fetch data from the server and populate in my app.
I need some ideas to establish server communication between the smart device and the server. My questions are
What kind of server needed for mobile applications ? A cloud or a
regular web server is enough ?
What are the ways to connect the app with the server ? ( on cross
platform mobile development )
What is the secure way to communication with the server ?
What kind of server needed for mobile applications ? A cloud or a regular web server is enough ?
Because you are creating a hybrid mobile application you can use any type of server side technology, it doesn't matter is it a classic web server technology (using Java, PHP or .NET) or some kind of cloud technology like Parse.com.
You also don't need to create anything from scratch. Best course of action would be to use some kind of micro RESTFul framework(like PHP Falcon or Java Play Framework). Read more about them here.
But, there's always a but. You can't use server side technology for classic content generation, you only need to use it to send data to your hybrid application. I will explain this later.
There's also an alternative to RESTFul services, you can create a webservice, again using Java, PHP or .NET.
What are the ways to connect the app with the server ? ( on cross platform mobile development )
You would use AJAX as a technology (in case of RESTFul), rest depends on you. You would probably do it in JSON format (or JSONP if you are doing cross-domain calls, but you don't need to think about JSONP when creating a hybrid application).
If you intend to use a web service then you would use a SOAP connection and communicate via XML format.
No matter which server side technology you use you will always use AJAX on a client side.
Now let me tell you why you should not generate your content on server side. Basically nothing can prevent you from doing that, you can generate your complete page on web server and just show it in PhoneGap app, it would still be a hybrid app. But, if you try to put this app in Apple store you will get yourself rejected.
What is the secure way to communication with the server ?
Security of course depends on server side technology. Every framework has its own kind of security handling, but all of them relay on HTTPS so you should not worry too much.
From the client side you can always encrypt JSON/XML data and send them using POST.
Examples:
If you want to use jQuery Mobile then take a look at this tutorial. It will show you basics of client - server side communication.
Since you are new to mobile application, ill try to give short answers
1) What kind of server needed for mobile applications ? A cloud or a regular web server is enough ?
A regular web server is good.
2) What are the ways to connect the app with the server ?
via web-services
3) What is the secure way to communication with the server ?
Use HTTPS webservices (SOAP, REST), HTTPS secures the transmission.
Above is a basic explanation for your quick help, I would recommend you to go through the documentation, and review some sample codes
This will really help you Sample

Webserver,cloud anything is good for restful service
for security purpose you can use POST parameter to send and recieve data or if you want more security then you can encrypt and decrypt data through secure algorithm
Basically my android project is around making a form to be filled up by the user of the app. And send this data to the php server. The data may be collected offline so the app should also save the datas unless its in the reach of wifi or gprs network. I'm early beginner to android and got stuck in between. Can any one suggest me a similar project sample so tat I could make a study and learn the stuff.
Sounds to me like a good use case for a hybrid client-server app. Use the mobile device to collect forms and store their results in a SQLite database. Whenever an appropriate wireless network is available, connect up with the server-based app and upload all the data. There are many good ways to do this, but for starters, consider making the server app implement a RESTful API and have the mobile device use this API to send in the data. If messing around with a server sounds like fun, I've had good luck with MySQL + CakePHP. One of the cool aspects of CakePHP is it gives you RESTful access to your database almost for free. Or, you can use something like Google App Engine and let someone else worry about administering the server.
