Permissions Plugin for Xamarin

Simple cross platform plugin to request and check permissions.

Want to read about the creation, checkout my in-depth blog post.

The Future: Xamarin.Essentials

I have been working on Plugins for Xamarin for a long time now. Through the years I have always wanted to create a single, optimized, and official package from the Xamarin team at Microsoft that could easily be consumed by any application. The time is now with Xamarin.Essentials, which offers over 50 cross-platform native APIs in a single optimized package. I worked on this new library with an amazing team of developers and I highly highly highly recommend you check it out.

I will continue to work and maintain my Plugins, but I do recommend you checkout Xamarin.Essentials to see if it is a great fit your app as it has been for all of mine!

Setup

• Available on NuGet: http://www.nuget.org/packages/Plugin.Permissions
• Install into your PCL/.NET Standard project and Client projects.
• Development NuGet: https://www.myget.org/feed/Packages/xamarin-plugins

Platform Support

*See platform notes below

Build Status:

Android specific in your BaseActivity or MainActivity (for Xamarin.Forms) add this code:

public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Android.Content.PM.Permission[] grantResults)
{
    PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode, permissions, grantResults);
    base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}

Android Setup

This plugin uses the Xamarin.Essentials, please follow the setup guide.

Xamarin.Essentials.Platform.Init(this, bundle);

iOS Specific

Based on what permissions you are using, you must add information into your info.plist. Please read the Working with Security and Privacy guide for keys you will need to add.

API Usage

You are able to check and requests permissions with just a few lines of code:

Check permission:

PermissionStatus status = await CrossPermissions.Current.CheckPermissionStatusAsync<CalendarPermission>();

Request permission:

PermissionStatus status = await CrossPermissions.Current.RequestPermissionAsync<CalendarPermission>();

Additionally on Android there is a situation where you may want to detect if the user has already declined the permission and you should show your own pop up:

bool shouldShow = await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Calendar);

Available Permissions

• CalendarPermission
• CameraPermission
• ContactsPermission
• LocationPermission
• LocationAlwaysPermission
• LocationWhenInUsePermission
• MediaLibraryPermission
• MicrophonePermission
• PhonePermission
• PhotosPermission
• RemindersPermission
• SensorsPermission
• SmsPermission
• StoragePermission
• SpeechPermission

In Action

Here is how you may use it with geolocation:

try
{
	var status = await CrossPermissions.Current.CheckPermissionStatusAsync<LocationPermission>();
	if (status != PermissionStatus.Granted)
	{
		if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Location))
		{
			await DisplayAlert("Need location", "Gunna need that location", "OK");
		}

		status = await CrossPermissions.Current.RequestPermissionAsync<LocationPermission>();
	}

	if (status == PermissionStatus.Granted)
	{
		//Query permission
	}
	else if (status != PermissionStatus.Unknown)
	{
		//location denied
	}
}
catch (Exception ex)
{
  //Something went wrong
}

IMPORTANT

Android:

You still need to request the permissions in your AndroidManifest.xml. Also ensure your MainApplication.cs was setup correctly from the CurrentActivity Plugin.

Windows 10 UWP

UWP has a limited set of supported permissions. You can see the documentation above, but current support: Contacts, Location, and Sensors.
