The first step in working with Android permissions is to declare the permissions in the Android manifest file. This package will backport permission specific APIs to older versions of Android, providing one common interface without the need to constantly check the version of Android that the app is running on. It is strongly recommended that Xamarin.Android projects include the NuGet package. For example, if the app requires permission for the camera, then Google Play will not show the app in the Google Play Store on a device that does not have a camera installed. It is possible that permissions for hardware may affect how the app is filtered by Google Play.

This document will discuss how to add permissions to a Xamarin.Android application and how apps that target Android 6.0 (API level 23) or higher should perform a run-time permission check. These backported APIs will automatically check the version of Android on the device so it is not necessary to perform an API level check each time. The Android Support Library backports some of the new APIs for permissions to older versions of Android. The whole workflow of checking and requesting permissions is known as a run-time permissions check, and can be summarized in the following diagram: By understanding the rationale, the user can make an informed decision if they wish to grant the permission and understand the repercussions if they do not. Once the user understands the rationale, the app can request permission from the user. If the user grants permission to READ_EXTERNAL_STORAGE, then the WRITE_EXTERNAL_STORAGE permission is automatically granted at the same time.īefore requesting one or more permissions, it is a best practice to provide a rationale as to why the app requires the permission before requesting the permission. For example, the STORAGE permission group holds both the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions. When the user grants permission to one member of a permission group, Android automatically grants permission to all members of that group. A permission group will hold permissions that are logically related. It is possible that a permission which was categorized as a "normal" permission may be elevated in future API levels to a dangerous permission.ĭangerous permissions are further sub-divided into permission groups. The category that a permission belongs to may change over time.

Sending or receiving an SMS message is an example of an action requiring a dangerous permission. These must be explicitly granted by the user. Dangerous Permissions – In contrast to normal permissions, dangerous permissions are those that protect the user's security or privacy.

Please consult the Android documentation for a complete list of normal permissions. Android 6.0 will automatically grant normal permissions at the time of installation.

Normal Permissions – These are permissions which pose little security risk to the user's security or privacy.

Permissions are divided into two categories: If the app does not have permission, then it must make requests using the new APIs provided by the Android SDK for the user to grant the permissions. It lists the various permissions and allows the user to enable or disable permissions:Īndroid apps must check at run-time to see if they have permission to access a protected resource. This screenshot shows the permission settings for the Google Contacts app.

Starting in Android 6.0 (API level 23), users were given more control over permissions they can grant or revoke permissions as long as the app is installed on the device.

Once the app is installed, there is no way to revoke the permissions except by uninstalling the app. If the user did not grant the permissions, then the app would not be installed.

For apps that targeted Android 5.1 (API level 22) or lower, the permission request occurred when the app was installed.

Android has two different workflows for obtaining the user's consent for those permissions: Permissions are declared in the AndroidManifest.xml by the application developer when the app is developed. Android will throw a if an app tries to access a protected resource without permission. For example, an application cannot access the GPS on a device without explicit permission from the user. The user must explicitly grant permission to the app before it may use these resources. Android applications run in their own sandbox and for security reasons do not have access to certain system resources or hardware on the device.
