I am working in xamarin pcl project , I am trying to keep sliding drawer in my pcl project but i dont know how to do that .
Are you using Xamarin.Forms?
If not, i would advice to use a framework like MvvmCross (https://github.com/MvvmCross/MvvmCross)
This would enable you to split the actual implementation of the drawer / hamburger menu into the different UI projects like iOS and Android(maybe WP8 too).
Since those platforms all behave differently, for example Android uses Fragments which are replaced inside the activity containing your navigation drawer, you should use a custom presenter to determine where you want the specific platform to navigate to.

I need to design bottom navigation bar like I attached image using xamarin.forms common code for both android and IOS. Can anybody refer any link or library tool to do this?
You should check the xamarin community toolkit, this is certainly possible to create with the tabview.

Is there a way to define a Label in Xamarin Forms (XAML or code-behind) AppXYZ that can be updated from the Xamarin Android AppXYZ.Android: MainActivity.cs and AppXYZ.iOS:Main.cs? i.e. upon an event in Android (e.g. BlueTooth) set a short text in a common Forms elements? After viewing many example, no clarity yet. MessageCenter perhaps?
In Android Project: MainActivity.cs (for example):
FormsAppXYZ.LabelXYZ.Text = "Updated string";
If not possible, then proper way to do this with Xamarin Android Native ? appreciated since I'll have to mix in the label into a shared Xamarin Forms Tabbed GUI.
Depending on how much Bluetooth work you need to do, my first suggestion would be to use MessagingCenter as you have already alluded to.
The other obvious approach would be to use a third party plugin, as I don't believe Xamarin have released one. I am currently aware of these two:

Is it possible to mix iOS Storyboards and Xamarin Forms within one application? I have a bunch of views that are easier to be created in Forms, but some which are heavily customized so we would need to create some of them in native code.
I would like to use Storyboards to create the native parts, but can't seem to find a way to navigate from a Forms page to a Storyboard and vice versa.
I don't mind doing it from code, just need to know the direction to look into and if it's even possible.
You can create native views using the concept of Custom Renderers (see links below). The idea is that you create a Xamarin Forms Control that's shared between all platforms and which old common properties (like colors, general data etc), and do the native rendering on the iOS/Android/WP projects.
So, for your storyboard, you can create it usign Xamarin.iOS, and render using a Custom Renderer. The link posted by #GSerg in the comments have some information and examples, but you can take a closer look at the oficial documentation as well:
Introduction to Custom Renderers
Customizing Controls on Each Platform
Customizing Control Rendering in Xamarin.Forms (video)
Also, for more real world examples you can take a look at the Xamarin Forms XLabs project.
Thanks to Rafael Steil's answer. I looked at the links and a few more samples.
Notably:
Custom Renderer Map
Using Xamarin Forms alongside Storyboard
And I created a sample project to show the back-and-forth navigation between Xamarin Forms and pages created in Storyboards. You can find it over here:
Xamarin Forms Mixed with Native
I am using xamarin.forms mvvm light architecture and targeting Android & iOS.
I am currently writing custom renderer for navigation drawer(MasterDetailPage).
I am currently writing custom renderer for Android and i have tried many things.
Currently my MasterDetail Page renders according to OS's default behaviour i.e. in Android master page starts below the app bar but i wanted my master page to popover app bar or start above the app bar like gmail,stack exchange android app etc
use this theme Theme.AppCompat.Light.NoActionBar for the expected behaviour
There exists one already, as of this writing it is out of date though (not targeting Xamarin Forms 2): https://github.com/nativecode-dev/oss-xamarin. Perhaps you can use that?
I'm trying to add a Xamarin.Forms page to an existing Xamarin Android app.
I'm struggling to figure out how to mix native Xamarin Android pages and Xamarin.Forms pages.
All the articles and examples I have seen describe either Forms or Xamarin apps and not a hybrid of the two.
The best idea I have read about so far is to add a native stub and replace the content with Xamarin.Forms content but I'm not sure how to achieve this.
Update
I'm using MvvmCross so my android view is inherited from MvxActivity. I have a StackLayout containing views using Xamarin.Forms. How do I get XF to convert to android code so I can use with SetContentView?
When you create a new Xamarin.Forms project, for instance with a SharedProject approach, it will create the launcher project and initial class file that will be executed for you for each platform.
For instance on Android this is in MainActivity.cs. If you look inside this file you will notice that it inherits from AndroidActivity which in turn inherits from Activity, which is the typical class used on activities.
So you have two options available for you to create a mixed hybrid solution:-
1) Inherit from AndroidActivity in your platform-specifc stub-page should you want to display Xamarin.Forms content, or alternatively
2) Inherit from Activity, and do the same as usual.
If you want to display a Xamarin.Forms page from the stub-page you can then just use some boiler-plate code such as the following in the OnCreate method:-
SetPage({some class that returns a Xamarin.Forms.Page object, i.e. ContentPage});
You can then use the normal navigation that is specific to Android to either display a Xamarin.Forms page or a platform-specific Activity page.
