how to save & restore Webview State?

Question

when i use backup & restore Webview state ,i recive this message : the webpage at x Address might be temporarity down or may have moved permanently to a new web address.

Answer 1

restoreState was never reliable. That's perhaps why the documentation now says this.

If it is called after this WebView has had a chance to build state (load pages, create a back/forward list, etc.) there may be undesirable side-effects. Please note that this method no longer restores the display data for this WebView.

And the corresponding entry for saveState() speaks thus:

Please note that this method no longer stores the display data for this WebView.

what you really should do inside the onCreate method is to call webView.loadUrl() if you want to display the last visited url, please see this answer:

If you are concerned about the webview reloading on orientation change etc.

you can set your Activity to handle the orientation and keyboardHidden changes, and then just leave the WebView alone
