Clearing All Cached Items Created By A WebView?

I've got a WebView in my app. When the user logs out of my app, I'd like to delete all cached resources the WebView may have created. Looking at an emulator, I see the following fi

Solution 1:

try this

mWebView.clearCache(true);
mContext.deleteDatabase("webview.db");
mContext.deleteDatabase("webviewCache.db");

Solution 2:

This is the only code that saved my day!!

 CookieSyncManager.createInstance(this);         
 CookieManager cookieManager = CookieManager.getInstance();        
 cookieManager.removeAllCookie();

My scenario:

• Once logged in via linkedIn with the webview. The webview saves the login details. I need my app to clear this when the user signs out of the application. All the other approaches did not work for me.

Solution 3:

Only posting here because commenting can be ugly

clearCache() will work because:

From the doc:

Clear the resource cache. Note that the cache is per-application, so this will clear the cache for all WebViews used.
