void removeAllCookie ()
This method was deprecated
in API level 21.
Use removeAllCookies(ValueCallback)
instead.
Removes all cookies.
void removeAllCookies (ValueCallback<Boolean> callback)
Removes all cookies.
This method is asynchronous.
If a ValueCallback
is provided,
onReceiveValue()
will be called on the current
thread's Looper
once the operation is complete.
The value provided to the callback indicates whether any cookies were removed.
You can pass null
as the callback if you don't need to know when the operation
completes or whether any cookies were removed, and in this case it is safe to call the
method from a thread without a Looper.
Parameters | |
---|---|
callback |
ValueCallback :
a callback which is executed when the cookies have been removed
|
void removeExpiredCookie ()
This method was deprecated
in API level 21.
The WebView handles removing expired cookies automatically.
Removes all expired cookies.
void removeSessionCookie ()
This method was deprecated
in API level 21.
use removeSessionCookies(ValueCallback)
instead.
Removes all session cookies, which are cookies without an expiration date.
void removeSessionCookies (ValueCallback<Boolean> callback)
Removes all session cookies, which are cookies without an expiration date.
This method is asynchronous.
If a ValueCallback
is provided,
onReceiveValue()
will be called on the current
thread's Looper
once the operation is complete.
The value provided to the callback indicates whether any cookies were removed.
You can pass null
as the callback if you don't need to know when the operation
completes or whether any cookie were removed, and in this case it is safe to call the
method from a thread without a Looper.
Parameters | |
---|---|
callback |
ValueCallback :
a callback which is executed when the session cookies have been removed
|
void setAcceptCookie (boolean accept)
Sets whether the application's WebView
instances should send and
accept cookies.
By default this is set to true and the WebView accepts cookies.
When this is true
setAcceptThirdPartyCookies
and
setAcceptFileSchemeCookies
can be used to control the policy for those specific types of cookie.
Parameters | |
---|---|
accept |
boolean :
whether WebView instances should send and accept
cookies
|
void setAcceptFileSchemeCookies (boolean accept)
Sets whether the application's WebView
instances should send and
accept cookies for file scheme URLs.
Use of cookies with file scheme URLs is potentially insecure and turned
off by default.
Do not use this feature unless you can be sure that no unintentional
sharing of cookie data can take place.
Note that calls to this method will have no effect if made after a
WebView
or CookieManager instance has been created.
Parameters | |
---|---|
accept |
boolean
|
void setAcceptThirdPartyCookies (WebView webview, boolean accept)
Sets whether the WebView
should allow third party cookies to be set.
Allowing third party cookies is a per WebView policy and can be set
differently on different WebView instances.
Apps that target KITKAT
or below
default to allowing third party cookies. Apps targeting
LOLLIPOP
or later default to disallowing
third party cookies.
Parameters | |
---|---|
webview |
WebView :
the WebView instance to set the cookie policy on |
accept |
boolean :
whether the WebView instance should accept
third party cookies
|
void setCookie (String url, String value, ValueCallback<Boolean> callback)
Sets a cookie for the given URL. Any existing cookie with the same host, path and name will be replaced with the new cookie. The cookie being set will be ignored if it is expired.
This method is asynchronous.
If a ValueCallback
is provided,
onReceiveValue()
will be called on the current
thread's Looper
once the operation is complete.
The value provided to the callback indicates whether the cookie was set successfully.
You can pass null
as the callback if you don't need to know when the operation
completes or whether it succeeded, and in this case it is safe to call the method from a
thread without a Looper.
Parameters | |
---|---|
url |
String :
the URL for which the cookie is to be set |
value |
String :
the cookie as a string, using the format of the 'Set-Cookie'
HTTP response header |
callback |
ValueCallback :
a callback to be executed when the cookie has been set
|
void setCookie (String url, String value)
Sets a cookie for the given URL. Any existing cookie with the same host, path and name will be replaced with the new cookie. The cookie being set will be ignored if it is expired.
Parameters | |
---|---|
url |
String :
the URL for which the cookie is to be set |
value |
String :
the cookie as a string, using the format of the 'Set-Cookie'
HTTP response header
|
Object clone ()
Creates and returns a copy of this object. The precise meaning
of "copy" may depend on the class of the object. The general
intent is that, for any object x
, the expression:
will be true, and that the expression:x.clone() != x
will bex.clone().getClass() == x.getClass()
true
, but these are not absolute requirements.
While it is typically the case that:
will bex.clone().equals(x)
true
, this is not an absolute requirement.
By convention, the returned object should be obtained by calling
super.clone
. If a class and all of its superclasses (except
Object
) obey this convention, it will be the case that
x.clone().getClass() == x.getClass()
.
By convention, the object returned by this method should be independent
of this object (which is being cloned). To achieve this independence,
it may be necessary to modify one or more fields of the object returned
by super.clone
before returning it. Typically, this means
copying any mutable objects that comprise the internal "deep structure"
of the object being cloned and replacing the references to these
objects with references to the copies. If a class contains only
primitive fields or references to immutable objects, then it is usually
the case that no fields in the object returned by super.clone
need to be modified.
The method clone
for class Object
performs a
specific cloning operation. First, if the class of this object does
not implement the interface Cloneable
, then a
CloneNotSupportedException
is thrown. Note that all arrays
are considered to implement the interface Cloneable
and that
the return type of the clone
method of an array type T[]
is T[]
where T is any reference or primitive type.
Otherwise, this method creates a new instance of the class of this
object and initializes all its fields with exactly the contents of
the corresponding fields of this object, as if by assignment; the
contents of the fields are not themselves cloned. Thus, this method
performs a "shallow copy" of this object, not a "deep copy" operation.
The class Object
does not itself implement the interface
Cloneable
, so calling the clone
method on an object
whose class is Object
will result in throwing an
exception at run time.
Returns | |
---|---|
Object |
a clone of this instance. |
Throws | |
---|---|
CloneNotSupportedException |
