↳ | android.webkit.GeolocationPermissions |
This class is used to manage permissions for the WebView's Geolocation
JavaScript API.
Geolocation permissions are applied to an origin, which consists of the
host, scheme and port of a URI. In order for web content to use the
Geolocation API, permission must be granted for that content's origin.
This class stores Geolocation permissions. An origin's permission state can
be either allowed or denied. This class uses Strings to represent
an origin.
When an origin attempts to use the Geolocation API, but no permission state
is currently set for that origin,
WebChromeClient.onGeolocationPermissionsShowPrompt()
is called. This allows the permission state to be set for that origin.
The methods of this class can be used to modify and interrogate the stored
Geolocation permissions at any time.
