App Permissions Android 51. Whatsapp maintains a little higher version of their app than that available on the play store over here (just in case you're interested). It is stuck on the 'appear on top' screen and the car doesn't connect.
Only the permissions that are defined in the manifest file can be requested at run time. Summary of what's new in xamarin.android 9.4.0.51. “users can revoke an app's permissions at any time.“
In my case, upon the first build of my app, a popup appears and asks allow myapp to access photos and media on your device?.
App permission is one of the features that exclusive to the android version 6.0 and later, versions. The new permissions service, which costs $1, takes advantage of google's set of tools for accessible app development, which is designed to help in creating apps for users with disabilities. If the android 5.1.1 (api 22) or lower, the permission is requested at the installation time at the google play store. Apparently, there's a problem when requesting more than one permission at the same time in android.
