GeolocationPermissions
extends Object
java.lang.Object | |
↳ | 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.

void allow (String origin)
Allows the specified origin to use the Geolocation API.
Parameters | |
---|---|
origin |
String :
the origin for which Geolocation API use is allowed
|
void clear (String origin)
Clears the Geolocation permission state for the specified origin.
Parameters | |
---|---|
origin |
String :
the origin for which Geolocation permissions are cleared
|
void clearAll ()
Clears the Geolocation permission state for all origins.
void getAllowed (String origin, ValueCallback<Boolean> callback)
Gets the Geolocation permission state for the specified origin.
Parameters | |
---|---|
origin |
String :
the origin for which Geolocation permission is requested |
callback |
ValueCallback :
a ValueCallback to receive the result of this
request. This object's
onReceiveValue()
method will be invoked asynchronously with a boolean
indicating whether or not the origin can use the
Geolocation API.
|
GeolocationPermissions getInstance ()
Gets the singleton instance of this class. This method cannot be
called before the application instantiates a WebView
instance.
Returns | |
---|---|
GeolocationPermissions |
the singleton GeolocationPermissions instance
|
void getOrigins (ValueCallback<Set<String>> callback)
Gets the set of origins for which Geolocation permissions are stored.
Parameters | |
---|---|
callback |
ValueCallback :
a ValueCallback to receive the result of this
request. This object's
onReceiveValue()
method will be invoked asynchronously with a set of
Strings containing the origins for which Geolocation
permissions are stored.
