i'm making android app that's complex javascript app embedded in web view. web view refreshes every time main activity's destroyed (ie due rotation, button press, etc). to preserve state of web page, override onsaveinstancestate , onrestoreinstancestate : @override protected void onsaveinstancestate(bundle outstate) { super.onsaveinstancestate(outstate); // save state of webview webview.savestate(outstate); } @override protected void onrestoreinstancestate(bundle savedinstancestate) { super.onrestoreinstancestate(savedinstancestate); // restore state of webview webview.restorestate(savedinstancestate); } this prevented refresh, fell short of preserving display state of web page, important me since user loses work in complex js app stored in display state. i tried manually handle configuration changes overriding onconfigurationchanged . method preserved state rotation , other config changes, display state lost when user...
