Install Visual Studio community edition on Windows, select mobile development with .NET to enable Android and iOS workflows, and note that iOS testing requires a Mac or cloud Mac solution.
Explore how Xamarin forms define content pages and elements such as entries and text, using opening and closing tags, and learn how containers arrange controls for Android and iOS.
Learn how to use a StackLayout container to stack UI elements like entries and images, adjust margins for a clean cross-platform layout, and prepare for user interaction handling.
Create and wire up a button click event in Xamarin.Forms by naming elements in the markup and implementing the handler in the C# code-behind.
Test iOS apps on the macOS iOS simulator by selecting the iOS project and a device such as the iPhone 10, then launch to verify native controls and navigation.
Define the Android main activity to locate the database file path using environment special folders. Pass this path to the app via a shared class in the Xamarin Forms project.
Create a C# model class to map entries to a table, with properties for name, last name, email, phone, and address, and use primary key attributes for an auto-incremented ID.
Define the list view in the content page and bind its items source to the contacts list, converting it to an enumerable, then preview how elements render in the list.
Explore how to display list items in Xamarin.Forms by creating a data template and binding properties such as name and email to text cells, with styling for the detail text.
A few years ago I wanted to start developing mobile apps, back then for some reason for the Windows Phone 7 OS, and I just didn't understand what I was finding on Google, too advanced for a newbie like me. I felt overwhelmed, even though I had some (very light) programming experience, this seemed too complicated, maybe that was why it was one of the latest subjects in college (and I was just starting out).
And then I heard about this event that Nokia was having for developers, two full days of learning to build Windows Phone 7 and S40 apps, and we would start with Windows Phone. So my mom, with I'm sure a few efforts, gave me just enough money for one day, to travel to the big city, get to the event, have something to eat, and return home. So I skipped school that day, and went to the event, and luckily that day it would be about Windows Phone 7, and I say luckily because a few minutes by the instructor that day completely changed my life, and I mean this in every sense of the word.
In literally just about 30 minutes, this guy perfectly explained how to build Windows Phone 7 apps, and a world of opportunities opened for me, I would go ahead and build dozens of apps for WP7, WP8, Windows 8, and Windows 8.1 thanks to that quick lecture
The reason I'm writing about this story, is because I want you to have the same opportunity that I did back then, so you too can start building apps, and with no need from your loving parents to sacrifice some of the money they may very well lack, this course is entirely free. Hoping that this course does to your professional career what those 30 minutes did for mine all those years ago.
If you are a complete beginner on app development, I made this course with you in mind, so after just a few minutes you unlock a world of posibilites with the apps that you can build.
And even better, Xamarin Forms unlocks more doors now by itself than Windows Phone 7 did back then. Xamarin Forms allows you to build NATIVE both Android and iOS apps reusing one code base.
So, if you are a complete beginner, take this course, and at the end, you will know how to:
Build iOS apps and
Build Android apps
By 100% reusing C# and XAML code!
Add SQLite local databases to your apps
Jumpstart your mobile app development career, don't wait for the University to teach you in the last semesters, act now and start building iOS and Android apps today.
