How to use Google map - xamarin.forms

I am working on Xamarin forms. I am confused as to which Plugin for google map I should use to avoid problems later on.
Are these two the same? Are they providing the same set of functionalities and work well in Android and iOS.
1) Xamarin.Forms.maps
2) Xamarin.Forms.GoogleMap
Need your guidance.
Thanks

Xamarin.Forms.Maps just uses the native map APIs on each platform and provided by Xamarin. There are some APIs which are abstration for displaying map. You can see the API referernce here.
On the other hands, Xamarin.Forms.GoogleMap is 3rd party maps library for Xamarin.Forms optimized for Google maps. As I know, this is forked from Xamarin.Forms.Maps. Please refer to Xamarin.Forms.GoogleMaps project.

Xamarin.Forms.GoogleMap is no longer so you have no choice, you must use Xamarin.Forms.Maps only.

I tried to achieve it using binding feature available in xamarin but end up with failure. As binding feature only useful in case AAR(Android archive) or Jar library. I was looking for some example or guidance where something like calling/chat/image editor (i.e. where UI and coding involve) has been implemented in xamarin by using native API.
You can use SendBird Messaging SDK and Chat API for Mobile Apps and Websites.
It has support for Xamarin officially and It has a nuget package NOT OFFICIAL for Xamarin.Forms It's works perfectly you can download here
Additionally, you can use this sample on Github that use this nuget package.
This answer is not spam. It's only a recommendation
You can use CometChat Xamarin SDK, It fits your above requirements perfectly. It has Audio/Video call functionalities builtin along with Audio/video broadcast & screen share. For more information you can check out the documentation at the following link:

How to implement google map API in C# Application?

I want to implement Google map API in my project.I have searched alot on internet but still i m not able to integrate it in my application. Any one help me how can i implement it in my application. Thanks in advance
CodePlex project : Use Google Maps API for .net
You can use some wrapper http://www.codeproject.com/KB/aspnet/csharp-google-static-map.aspx but I really think that it is better to do this in the Api native language (Javascript) and simply follow the documentation.

Facebook Connect for Qt

I am trying to use the facebook API provided by Nokia Developer:
http://www.developer.nokia.com/Community/Wiki/Facebook_Connect
I need to know what library or files should i include to connect to this API. And if you can provide me with any important guidelines it would be great.
Thanks,
Did you actually read the page you linked to? The first line has a link to the download location and the entire page is full of examples of how to use the API.
However, if you did follow the download link you'd see this:
Facebook is deprecating the old REST api upon which this library is
based on. The new api is called facebook graph api and that should be
used, the rest api breaks all the time so its not a good idea to use
it. Please look at http://gitorious.org/qfacebook for a Qt
implementation of the new facebook graph API
Which makes your question somewhat irrelevant.
With Qt 5, you can now use the V-Play Facebook Qt Plugin.
It wraps the native Facebook SDK around a QML item and thus has the advantage that native login functionality and the whole Facebook Graph API is available cross-platform.
There is a free sample, documentation and tutorials available here: http://plugins.v-play.net/plugins/facebook/

Web Based Map application development

I am trying to develop a web based map application where the user can interact with the map. But I am new to this field and do not have much idea about how to approach this. Basically I want to use a static map created by me, so I think google map API s may not be used in this case. My development platform is unix. Can you please suggest what language I should use to write the server and also what kind of free tools can be used to implement the map part?
Thanx...
I suggest reading up on the Google Maps API 3. You can add overlays or even add your own tiles using the API. Specifically, I suggest looking into the GroundLayers section of the V3 API here GroundOverlays
