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.
