Keep in mind that your targetSdkVersion must be >= 23 and your emulator / device must be running Marshmallow to see the new permissions model.
This means there are a couple more things to consider when working with permissions for a Marshmallow app. For approved permissions, these can also be revoked at a later time. These permission can then be allowed or denied by the user. These are permissions that are requested while the app is running (instead of before the app is installed). It introduced the concept of runtime permissions. Marshmallow brought large changes to the permissions model. This made it easy for developers to deal with permissions, but wasn't the best user experience. The user had no way of changing permissions, even after installing the app. To request one of the many permissions, simply specify it in the AndroidManifest.xml:įor example, an application that needs to read the user's contacts would add the following to it's AndroidManifest.xml: There was no way to grant only certain permissions to the app and no way for the user to revoke certain permissions after the app was installed.Įxample of pre-Marshmallow permissions requested by the Dropbox app:įor an app developer, permissions were very simple. The user could either accept all the permissions and continue to install the app or decide not to install the app. When a user went to install an app from the Google Play Store, the user was presented a list of permissions that the app required (some people referred to this as a "wall of permissions". All permissions were handled at install-time. Permissions were much simpler before Marshmallow (API 23). If you to get started quickly, check out our guide on managing runtime permissions with PermissionsDispatcher. There are a number of libraries available to make runtime permissions easier. After Marshmallow, permissions must now be requested at runtime before being used. Full list of permissions can be found here. When the app needs to use any of the protected features of the device (sending network requests, accessing the camera, sending an SMS, etc) it must obtain the appropriate permission from the user to do so.īefore Marshmallow, permissions were handled at install-time and specified in the AndroidManifest.xml within the project. By default, an Android app starts with zero permissions granted to it.
