Essentials is a set of APIs for writing cross-platform compatible code. The File System Helpers is a class that contains a series of helpers to simplify locating the application's cache and data directories.
This code snippet provides an example of how to find the internal storage directory and the cache directory for an app:. The MediaStore is an Android component that collects meta data about media files videos, music, images on an Android device.

As you can imagine, this is the Android project. If you ever have written any native Android code in Kotlin or Java, this project will look very familiar. It has the Resources folder, which contains the drawable folders for images at different resolutions, layouts, and the MainActivity. Unlike in a Xamarin. The AppDelegate. Forms library and calls into the Counter shared project to find the application to run, including the UI.
There is also the Info. It is that time Now you have your new project created and you understand the solution structure better, it is time to actually write some code! Begin with the user interface. You will want a way of displaying the current count and a button that makes the count increase. Open the Main. XAML file in the Counter project folder.
To learn more about different layout types in Xamarin. Forms, visit Layouts in Xamarin. Forms on docs.
Delete the StackLayout element from the Main. XAML file and replace it with the following markup:. The two main things here to take note of are the x:Name attribute on the Label element and the Clicked attribute on the Button element.
The x:Name attribute is there so you can refer to the component in code. You do this so you can update the value as the button is clicked. As you can guess, the Clicked attribute on the button determines which method is called in code when the button is clicked.
In this case it will be a method called IncrementCounterClicked. All Xamarin. Forms XAML files have an associated. Visual Studio and the Xamarin middleware use the file name, namespace, and class inheritance to automatically link any components referred to in the.
