[<get: Android.Runtime.Register("getKeysNeedingPermission", "()Ljava/util/List;", "", ApiSince=29)>]
member this.KeysNeedingPermission : System.Collections.Generic.IList<Android.Hardware.Camera2.CameraCharacteristics.Key>

Property Value

List of camera characteristic keys that require the android.Manifest.permission#CAMERA permission. The list can be empty in case there are no currently present keys that need additional permission.

Attributes

Remarks

Returns a subset of the list returned by #getKeys with all keys that require camera clients to obtain the android.Manifest.permission#CAMERA permission.

If an application calls CameraManager#getCameraCharacteristics without holding the android.Manifest.permission#CAMERA permission, all keys in this list will not be available, and calling #get will return null for those keys. If the application obtains the android.Manifest.permission#CAMERA permission, then the CameraCharacteristics from a call to a subsequent CameraManager#getCameraCharacteristics will have the keys available.

The list returned is not modifiable, so any attempts to modify it will throw a UnsupportedOperationException.

Each key is only listed once in the list. The order of the keys is undefined.
