I hope to get the data transfer info.
I have done the same thing on iPhone but not sure if wp7 sdk has the same function?
No, at the moment, there is no data transfer API. I assume you mean total data usage from other apps and the phone in general. You could monitor your own app by manually making web requests and storing the bytes used but there's no way to monitor how much is being used by other apps.

I am a junior Android Developer and I intend to develop a little cross platform with Xamarin.
This app is just a FAQ with an enormous amount of data which will not change in the time (additionally I would like to add a quiz). I want the app be multilingual and be accessible without Internet Connection.
My worry is about the choice of the method of storage of the data and the handling of translation. Which method should you recommend?
I’m working on technical part of a project for big bank and looking for information about using Secure Element (SE) that is embedded into Google Nexus 4.
What is a process to get access to SE?
I mean how to initiate a process with Google.
You may try to contact them directly, but Google will not give you access to (embedded) SE: they don't want competitors on their wallet application (specially on Android systems).
You can do this, current android version(4.0.4) has enabled access to SE without having support of platform vendor.

Depends what your ambition is, can you elaborate ? Loading an application of your own onto the secure element will require crypto keys that only Google can provide, and they probably never will, for many reasons.
Alternatively, you should be able to do the same with a SIM. It only takes a few tools to load and configure an application on a test SIM (with test SIM), then you can fit it into a phone and access it through the Open Mobile API (see the SEEK for Android open source project) which is available on many devices.
I working on a project were mobile users can receive alerts based on diferent factors, the server side will be implemented using the MVC framework.
My question is regarding the client side; what would be the most efficient way to send the alerts to the clients? is there any way to broadcast the alerts to each device or do I have to set up some system where each device pulls the data from the server on an interval of mins/seconds? I am afraid pulling the data every X secs/mins would create an unnesesary overhead on the mobile devices.
One way would be using SMS but SMS gateway services are expensive and not on my budget right now.
I haven't personally tried it, but this service might work for you:

It is free for limited use. Downside is it appears to be a separate install on the mobile device. This might means less control of the content of the message or its look. Upside is it looks quick and easy if you just need a proof of concept at this point.
HI,
I am building a small application using accelerometers on the phone. I hope I can get the accelerometer data from the phone and analyze them at my PC and then I can build a model based on these data and deploy the model on the phone.
But I just don't know how to get the data out of the phone.
Thanks a lot!
For testing you could write to Debug when running from within Visual Studio.
Beyond that you'll need to send the data to a web service running on the local PC.
As a third alternative, you could save the data to IsolatedStorage on the device and then use http://wp7explorer.codeplex.com/ to get this files off the device.
If you log the data on the phone, you can later (say when you touch a button) send the data to a web service stored on your computer.
If you log the data in a string then your web service should expose a method that accepts a string input. It should be easy to setup and it is really easy to use from the phone, just use the Add Service Reference wizard to connect to it.
I'm trying to write the most basic application for windows phone 7 and want to be able to send files (specifically XML in case that changes anything) to my app. Currently I have a WCF service setup so I can send push notifications through it. The problem is that there is a limit on the amount of raw data I can send via a push notification.
My solution to this is to send the initial push notification (either tile or raw) to alert my application that I want to send a file to it and then make the app somehow communicate with a server (everything is on my personal computer btw - I'm just trying to figure out how things work) - from which the app will recieve/download the files.
What is the easiest way to accomplish this? Note that I'm not concerned with security or anything like that.
Clarification - the question is essentialy: how do I transfer files from/to a server to/from the phone? Assume everything else was handled - the app is up and running and the user has given or will give permissions to every possible thing he may give his permission to.
Unfortunately, the total size of a push notification (including HTTP headers) is 1kb. This means that it can't be used to send large amounts of data.
Instead of sending the whole file, send a notification (raw or toast—as appropriate) which should be treated by the application as a trigger to go and retrieve the new file/data/whatever from the server. It may also be worth checking for new messages when your app starts. However, if when you start the app it will notify the server that it is ready to receive raw notifications and such messages will be sent indicating new content is available, it may be unnecessary to add this extra check.
To transfer files to/from the phone you will need to use either HttpWebRequest or WebClient as this is the only way to use HTTP on the device and HTTP is the only protocol currently available to transfer data.
While WebClient may appear to be easier to use than HttpWebRequest it is less flexible and will automatically perform it's callback on the UI thread and if you're downloading files in the background you almost certainly don't want this.
There is no way to transfer files to/from a conencted PC and have them exclusively available to your app.
First of all: you won't be able to do this approach automatically - the user will have to open your app to do that because WP7 SDK doesn't allow your app to run on background/start automatically once a push notification is received.
The only way to communicate with your server, at this point in time, is web services. If I were you, I would check for new information available once the app is started, if there is new info, I would call one or more web services which would return me all the information that I need.
If you want, you can use a timer to check for information periodically.
As I said, it will only work while your app is running (check the app lifecycle if you don't know it yet), WP7 doesn't allow apps to run in background, that is a serious limitation IMHO.
Good Luck,
Oscar
Maybe a little bit off topic but when I was thinking about file sharing in my WP7 app, I found two approaches:
Integrate an app with Dropbox
Use advanced explorer for WP7
You can use the WebClient class and the DownloadStringAsync method in order to download data from a web service .
A good example of this is Scott Guthrie's Twitter app from MIX10 .
