Second day with Xamarin

First day with Xamarin I able to create a new Xamarin app and integrated google maps and able to run it in the simulator.

If you read the previous post. I did make it working on the simulator using the Plugin.Permissions. However, when I ran the application in simulator it did work but I did not see any messages requesting for access permissions.

So, I am going to try to run the app on the device and see what happens.

The device I am going to use is Moto X running Android version 6.0.1. I am not gonna bore you with how to setup the device as you may not be going to use the same device. Just the basic stuff you need

  • USB drivers for the device
  • USB cable with data pins. Normal charging cables won't work.
  • Put the device in the debug mode.

First day with Xamarin

I started to create an app in Xamarin as I have been reading creating-mobile-apps-xamarin-forms by Microsoft. As a beginner I can say that it has taught me well.

Today I thought to try and spin up a simple app using Xamarin Forms. Let's start from the start I will be putting up all the issues, bus, Environment Setup steps I had to do while doing it.

Let’s get started.

Few conventions

  • # : Issue faced and resolution

First I would suggest to go through my friend Kael's blogs to get you started with the Android SDK setup. Few things which are important for Simulator.

HTML 5 tutorials Part 4 - Introduction to HTML5

Initial 3 parts Part1Part 2 and Part 3 we talked about the basics of HTML. I know most of the developers usually know about this stuff but it is always to brush up the basics before talking about the new stuff.

From this part we will start more on HTML5. First question that come to mind is what are the problems that are being solved by HTML5?

What is HTML5?

HTML5 is combination of new html elements and lots of new JavaScript APIs. I know this not a definition you were expecting but in reality this is it. So do we really need to call it HTML5? I think we can just say HTML as there will be new development but I guess there won't be any HTML6. It will be called on HTML.

Problems solved by HTML5


Previous we use one tag mostly in the web page design, I guess you know it is div. So for search engine to identify different parts of the page is by scanning the ids. So we need to keep consistent ids across the web pages. How this is solved by HTML5?

HTML5 provide us different html tags like header, main, footer which are used to specify the header content, main content and footer content of the page. Which makes is easy for the search engines to find specific contents of the page. It provides semantics for the web pages.

Mobile Friendly

Billions of people are now using mobile device and we want to make sure that our web pages are more suitable for mobile. If you open up a web page on mobile than you get an option to make the web page mobile friendly and read in mobile mode. As soon as you click on this option the web page completely change the design as per the mobile form factor. So it is easy to develop the web page for vast variety of mobile form factors.

Multi Media

HTML5 provide tags which can be used to host the multi media content like music, video, graphs and games. Now developer can develop a full fledged  game only in HTML5 and supporting CSS3 and javascript. So we do not need to use Flash or Silverlight to show videos or animated stuff on web pages. 

we will discuss these features in details as we move along the tutorials. I am sure there are other many important things which can be done easily in HTML5. Please add these to comments to share with others.

So here is the basic structure of HTML5 page that you can see.

HTML 5 tutorials Part 3 - Bacis of HTML - Lists and Links

In this part we are going to discuss different kind of lists and links.


Unordered List

unordered list is the bulleted list which is defined using the tags ul and li.


We can create nested lists with another ul tag within the li tag.

Ordered List

We can create ordered lists using the <ol> and <li> tags. Define in the same way as unordered list.

Definition List

Definition list are used to have term and put its definition next to it.

HTML 5 Tutorial Part 2 - Basics of HTML - Text Elements

So, we have learned about the basics of html5 in the Part 1 of the series of tutorials. In this part we will discuss different Text elements and their attributes.

Note: No examples included please try them in an HTML page and see for yourself that what would be the text like. This is done intentionally. Purpose is to make you aware of the elements and encourage to try them yourself.

Block vs Inline Elements

Block elements are used to define a block of content like div or p tag. They are rendered on different lines, we can make them render on the same line using css. But we can say that block element render in the next line.

Inline elements are used to defined links or acronyms like span tag, a tag. Text will be rendered inline to the content. 


H1 - Primary heading

Primary heading of the document. It is also used by the search engines. 

H2-H6 - Sub headings

HTML have subheadings ranging from H2 - H6. So you can have subheading H2, H3, H4, H5 and H6. You want to use one primary heading for your page and subsequent sub headings. 

Note: We do not want to use the heading for the font size, we can style the text using style sheets.


When client sees the pre tag it will honor the whitespace in the content.


Used to add the newline.


Adding a horizonal rule and you can style it look different way.

&nbsp - non breaking space

This is instruction to client that do not break a line at that point while doing text wrapping.

&lt and &gt

Used to show the less than and greater than signs in the web page. As we have < and > being used in the html and if you want to show those as symbols than we need to use &lt and &gt.

<sup> and <sub>

superscript and subscript used to set the text as superscript and subscript.


Information for citing a particular person or entity. It will be rendered as Italic text. you can style the cite in the styles. These are mostly for the search engines.

<abbr> and <acronym>

acronym is used to put the acronym and set the title attribute to set the full name of the acronym. Full name of the acronym will be shown in the mouse hover tooltip. abbr is used in the same way.

<em> and <strong>

emphasis and strong can be used to highlight the text. em is going to render the text in italic and strong is going to make the fond bold.


blockquoute and qoute are used to put some quoutes in the text. Blockqoute as the names suggest is block element and q is inline qoute.

Note: Please try them at home.
