Handle permissions in Xamarin.Forms
In this article, I present a way to handle permissions using Xamrin.Form.
Xamrin.Form
First let’s create an enum named EPermission. These are the permissions used in the project.
Now let’s create an interface named IPermissionDependency
Xamarin.Android
In Android, let’s create a class named PermissionDependency.cs
Inside the class PermissionDependency it was defined:
Delegate OnExecuteResponseRequestPermission: It is invoked in MainActivity, when user answer.
Delegate OnPermissionRequest: It is invoked in PermissionDependency after invoking OnExecuteResponseRequestPermission.
GetManifestPermission: Returns permission based on Enum EPermission.
CheckPermission: Method used to check the existence of permission.
RequestPermission: Invokes the RequestPermission dialog.
MainActivity
Xamarin.iOS
On iOS we have nothing to do.
After that done we just need to invoke these functions in xamarin.Forms. Let’s create a class for support named Permission.
MainPage.Xaml
MainPage.cs (bihand)
The project is available on github for contributions and improvements.
