Check app permissions android code#
This code uses features that are available with Xamarin.Essentials version 1.6.0 or later. The following code presents the general usage pattern for determining whether a permission has been granted and requesting it if it has not. If a permission is marked as it will always return Granted when checked or requested. Here is a guide to the currently available permissions: In addition there are differences when providing a single API for some permissions. However, each operating system has a different set of runtime permissions. Xamarin.Essentials attempts to abstract as many permissions as possible. Other platforms will always return false when calling this method. If the method returns true this is because the user has denied or disabled the permission in the past. The ShouldShowRationale method can be used to determine if an educational UI should be displayed. This limits the ability to know if the user denied the permission or if it is the first time prompting the user.

Android does not have this ability and and also defaults permission status to Disabled. On iOS you must specify a string that is displayed to the user. It is best practice to explain why your application needs a specific permission. Granted - The user granted permission or is automatically granted.Disabled - The feature is disabled on the device.Denied - The user denied the permission request.Unknown - The permission is in an unknown state.When using CheckStatusAsync or RequestAsync a PermissionStatus will be returned that can be used to determine the next steps: Further prompts must be handled by the developer to check if a permission is in the Denied state and ask the user to manually turn it on. Note, that on some platforms a permission request can only be activated a single time. var status = await Permissions.RequestAsync() If the user previously granted permission and hasn't revoked it, then this method will return Granted immediately and not display a dialog. To request a permission from the users, use the RequestAsync method along with the specific permission to request. On iOS if the status is Denied you should prompt the user to change the permission in the settings and on Android you can call ShouldShowRationale to detect if the user has already denied the permission in the past. If the status is Granted then there is no need to make other calls. iOS returns Unknown, while others return Denied. Each operating system returns a different default state if the user has never been prompted. It's best to check the status of the permission before requesting it. var status = await Permissions.CheckStatusAsync() Ī PermissionException is thrown if the required permission is not declared. To check the current status of a permission, use the CheckStatusAsync method along with the specific permission to get the status for.
(requestCode, permissions, grantResults) īase.OnRequestPermissionsResult(requestCode, permissions, grantResults) Īdd a reference to Xamarin.Essentials in your class: using Xamarin.Essentials Add the following code to all Activity classes: public override void OnRequestPermissionsResult(int requestCode, string permissions, .Permission grantResults) To handle runtime permissions on Android, Xamarin.Essentials must receive any OnRequestPermissionsResult. (this, savedInstanceState) // add this line to your code, it may also be called: bundle In the Android project's MainLauncher or any Activity that is launched Xamarin.Essentials must be initialized in the OnCreate method: protected override void OnCreate(Bundle savedInstanceState) Please ensure that Xamarin.Essentials is fully initialized and permission handling is setup in your app. This API uses runtime permissions on Android. To start using this API, read the getting started guide for Xamarin.Essentials to ensure the library is properly installed and set up in your projects. The Permissions class provides the ability to check and request runtime permissions.
