class CookieSyncManager : Runnable

kotlin.Any
↳	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 CookieManager.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 android.webkit.WebViewClient#onPageFinished. Note that even sync() happens asynchronously, so don't do it just as your activity is shutting down.
