I want to send data from a Linux client to a Linux/Windows server (maybe a shared host) and finally to an android application like this figure :
The data can be a text or stream video or audio.
What are the best technologies and languages for this scenario ? What is your suggestion ?
You can set up communication between same platform or cross platform clients/server. If you're sticking to *nix platform, you can try out with unix sockets. Since cross platform being a better option, you can implement the same thing using node.js and sockets. For better insight upon socket.io,please go through http://socket.io/

I want to establish communication between set top box and an android phone.
Is it better to use sockets or communicate via an embedded web server ?
1) An embedded web server can operate with any device having a browser, android devices included, with nice graphics/user interface. But it is heavier than solution 2.
2) Sockets is a lighter solution than a web server, but require an app (android) or a program (non-android) that know what to do and implement a user interface.
If the embedded web server is viable, probably is the easier solution.

I'm an Oracle Developer. The only programming language that I know is PL/SQL,
and I want to develop an application and upload it to Google Play and Apple's App Store so that it's available for download, and it should work offline.
Oracle Developer cannot deal with mobile apps, but there is Oracle Apex, and I can do a workaround, but it's hard and it cannot work offline.
The application is very small (just 5 or 6 pages and tables).
I want your help to pick up a programming language and tools with which I can do my task in a few days.
Go with PhoneGap. With PhoneGap you create apps using the web technologies you know and love: HTML, CSS, and JavaScript.

I want to develop a mobile application (android OS), and I want to know how could I use a WIFI connection to connect 2 or more mobiles ..?, which protocols, which API's..?
Any help please..
In order to communicate, they first have to discover each other in the network. Link will help you do discover.
If you already know the IP addresses of each other, then the problem is much simpler. RPC call or HTTP call or use Sockets. There is this server which can take http calls on the android application. So, both the applications can have servers hosted.
I've just looked up this link.

I am hopefully going to be embarking on producing a ios or android app that shows the x read of a till from a remote location over an internet connection. My question is wether it is possible to access a text file or xcel file, take the contents of the file and pull it to the app using android and ios? I have a way to get the x read to either a xls or txt file but need to know if I will be able to access it using a ios or android app?
Apologies for the basic explanation but I am quite new to this.
Yes, it's possible.
You will have to write a server program that runs on the PC, and communicate via network sockets.

I am trying to develop an application for my company which will allow logging into our Microsoft Exchange server and access mails.
I need some pointers on how to authenticate with the exchange server and download mails. I have a decent knowledge of Android. It would be really great if somebody could show me the right direction.
I would start by finding a Java library which supports one of the protocols that Exchange supports, e.g. ActiveSync or IMAP.
For starters, look into the JavaMail library:

There's also a commercial ActiveSync library that you may be able to use:

Finally, you may be able to use Microsoft's Exchange Web Services API:
