While working, I'm always having problems related to data sharing.
For example:
I have a computer connected to the printer but my laptop is not and I want to print a file, how do I easily move that file to the printer computer?
How to share a file from my mobile to laptop?
What I'm doing right now is moving the file using a USB disk, e-mail address or facebook.
You as developers, what are you doing for such purposes?
What I do is using network because its fast and safe.
But if I have a good internet connection I would suggest you to use Ziggs.io - Smoothly Share Content Between Devices.
The bad fact about Ziggs is that you need an internet connection to use it.
What I like about it that you don’t have to register, you can share files up to 500 MB per file and they don’t store messages.
More about Ziggs from their website:
What is Ziggs?
Ziggs is a platform that exists to facilitate peoples communications
Ziggs is like a meeting point with your devices, it helps you to
transfer contents between these devices smoothly.
Drag-and-drop PDFs,
images, videos, APK apps and other files directly into Ziggs.
Messages
are delivered directly from your device to the connected clients.
Ziggs doesn't store any type of data and doesn't require your personal
information.
Ziggs uses smart solutions based on client-side to share channel conversation history with new clients.
Exists channel clients will act as seeds, helps new clients to follow up with the conversation.
I've built my own cloud for this exact function:

However, this question should've been posted on some forum page, and not Stack Exchange.

My primary intention is to setup a VoIP session between 2 users A & B; Here the raw audio / video media bytes are fetched from A's browser are played in B's browser and vice versa.
The reason is that, when the user C & D are added into this call, we need not have to create a P2P mesh network which limits the performance.
Tried recording media with getUserMedia() and playback, but it is not real time. It also gives a bad user experience. (However, haven't experimented yet with videos of small chunks as 200 ms)
Is there any approach where I can get the raw bytes of the media and play it on other browser? Currently I have a server in between which can connect to both peers if required.
Any online examples or libraries are welcome.
Have already asked 2 questions in this regard with 100-100 bounties, but not much of use:
How to use libsrtp or similar library to decrypt/encrypt the WebRTC data stream?
How to integrate part of WebRTC as a static / dynamic library with the existing C++ code?

If i understand you well is you're looking on how to have more than two users on the session right? without using mesh topology
thats possible and configurable as well by means that some maybe active speaker or everyone is active speaker not only receiver whatever configuration you choose but to me it seems that you're asking for video conferencing
there are couple of tools for this the best one i might recommend is mediasoup its a SFU as selective fowarding unit mediasoup
I don't know if I understand correctly, but it is not likely that you will get raw video data and play it on the browser, it will just kill your bandwith and performance because the raw data is huge.
You need to use the compressed data ( media codec ex.H264 ) and you need a protocol to send and receive it. If you are looking for sub-second latency than webrtc is your best choice in here already. If you have a server in between, distribute your media through that server instead of Mesh. Check this out for webrtc network topologies:

I'm not very experienced with the codes on a cell phone. But I wanted to know how would someone be able to open up the com.sec.android application on a Samsung Galaxy S3 Cell Phone to see hidden contacts, text messages and other information ?
Thanks.
Generally Samsung phones comes with pre-installed applications by default. These applications are system applications which cannot be removed unless the device is rooted. Some applications use content providers to use sensitive information. Some malicious apps can use the content providers to get these sensitive information and can misuse them.

I need to make an Android application that sends large files (100-500 KB) over Bluetooth.
It is very important to preserve the integrity of the data, avoid any corruption of the files sent.
Please should I implement my own protocol?
Is there a suitable profile that I can use? (it seems profiles support is limited in Android...)
Any third party library?
This depends on the profiles that are implemented.
OPP - Object Push Profile can send files, but this is often limited to V-cards and in some case images.
FTP - File Transfer Profile can send larger files.
There is no specific application needed, you should be able to do it from native android as long as both devices supports the profile in question.
For example, enter the gallery and choose to share an image over Bluetooth, then select the receiving party.
Or enter file manager and choose to share file over Bluetooth.
If you want to write your own program that sends files, you can find the specifications for the profiles and protocols on Bluetooth.org or developer information on Bluetooth.com
Google just announced that they will add support for VoIP calls in its Gmail application.
Does someone know how this will work? Did they manage to write a web-based VoIP client, or will they require the user to have Google Talk installed and somehow (how?) call this app from the browser?
I'd also like to provide customers with a way to make/receive calls through their browser, so that they wouldn't have to install an SIP client.
Thank you.
Google don't use a VoIP client in a browser. Instead the browser is used to initiate a callback to a phone number you must have previously registered. Once you answer that call Google Voice will then ring the destination number you specified and then bridge the calls together.
I've just noticed that in my inbox. They ask you to accept their EULA to start installing Google Voice. So it's not really a browser solution.
There are several companies that have built VoIP clients as e.g. Java applets.
It is totally doable, although depending on the exact requirements it may be expensive and time consuming: for instance, echo cancellation is not exactly trivial when you need to deal with arbitrary audio drivers across any and all laptops, netbooks etc out there.
There are also consulting firms that can help with that.
Full disclaimer: I own one such company ;)
I want to send almost 4k size data to any cellphone by using bluetooth.
Firstly to do this, I need to find what stacks are in my phone and what stacks are acting when I send a data.
I really struggle to find the way; however, it is really hard.
If you know how to find it, please give me some information!!
See http://32feet.NET if you are talking about Windows Mobile. It is a managed library for Bluetooth, OBEX, and IrDA. We support both the Microsoft stack, but also have support for Widcomm. And now also Bluesoleil and Stonestreet One Bluetopia.
You can either send and receive the data as an OBEX message, or over a simple bluetooth connection. See a copy of the user's guide at http://www.alanjmcf.me.uk/comms/bluetooth/32feet.NET%20—%20User’s%20Guide.html
Goto "https://www.bluetooth.org/tpg/listings.cfm" type the name of your mobile. This will give you information on the Bluetooth stack inside and the profiles supported.
