CookieSyncManager

public final class CookieSyncManager
extends Object implements Runnable

java.lang.Object
   ↳ android.webkit.CookieSyncManager


This class was deprecated in API level 21.
The WebView now automatically syncs cookies as necessary. You no longer need to create or use the CookieSyncManager. To manually force a sync you can use the CookieManager method flush() which is a synchronous replacement for sync().

The CookieSyncManager is used to synchronize the browser cookie store between RAM and permanent storage. To get the best performance, browser cookies are saved in RAM. A separate thread saves the cookies between, driven by a timer.

To use the CookieSyncManager, the host application has to call the following when the application starts:

CookieSyncManager.createInstance(context)

To set up for sync, the host application has to call

CookieSyncManager.getInstance().startSync()

in Activity.onResume(), and call

 CookieSyncManager.getInstance().stopSync()
 

in Activity.onPause().

To get instant sync instead of waiting for the timer to trigger, the host can call

CookieSyncManager.getInstance().sync()

The sync interval is 5 minutes, so you will want to force syncs manually anyway, for instance in onPageFinished(WebView, String). Note that even sync() happens asynchronously, so don't do it just as your activity is shutting down.

Public methods

static CookieSyncManager createInstance(Context context)

Create a singleton CookieSyncManager within a context

static CookieSyncManager getInstance()

Singleton access to a CookieSyncManager.

void resetSync()

This method is deprecated. Calling resetSync is no longer necessary as the WebView automatically syncs cookies.

void run()

Starts executing the active part of the class' code.

void startSync()

This method is deprecated. Calling startSync is no longer necessary as the WebView automatically syncs cookies.

void stopSync()

This method is deprecated. Calling stopSync is no longer useful as the WebView automatically syncs cookies.

void sync()

This method is deprecated. Use flush() instead.

Protected methods

Object clone()

Creates and returns a copy of this Object.

void onSyncInit()
void syncFromRamToFlash()

This method was deprecated in API level 21. Use flush() instead.

Public methods

createInstance

Added in API level 1
CookieSyncManager createInstance (Context context)

Create a singleton CookieSyncManager within a context

Returns
CookieSyncManager CookieSyncManager

getInstance

Added in API level 1
CookieSyncManager getInstance ()

Singleton access to a CookieSyncManager. An IllegalStateException will be thrown if createInstance(Context) is not called before.

Returns
CookieSyncManager CookieSyncManager

resetSync

Added in API level 1
void resetSync ()

This method is deprecated.
Calling resetSync is no longer necessary as the WebView automatically syncs cookies.

resetSync() resets sync manager's timer.

run

Added in API level 1
void run ()

Starts executing the active part of the class' code. This method is called when a thread is started that has been created with a class which implements Runnable.

startSync

Added in API level 1
void startSync ()

This method is deprecated.
Calling startSync is no longer necessary as the WebView automatically syncs cookies.

startSync() requests sync manager to start sync.

stopSync

Added in API level 1
void stopSync ()

This method is deprecated.
Calling stopSync is no longer useful as the WebView automatically syncs cookies.

stopSync() requests sync manager to stop sync. remove any SYNC_MESSAGE in the queue to break the sync loop

sync

Added in API level 1
void sync ()

This method is deprecated.
Use flush() instead.

sync() forces sync manager to sync now

Protected methods

clone

Added in API level 1
Object clone ()

Creates and returns a copy of this Object. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should call super.clone() to create the new instance and then create deep copies of the nested, mutable objects.

Returns
Object a copy of this object.
Throws
CloneNotSupportedException

onSyncInit

Added in API level 1
void onSyncInit ()

syncFromRamToFlash

Added in API level 1
void syncFromRamToFlash ()

This method was deprecated in API level 21.
Use flush() instead.
