javascript - Android - save value on LocalStorage before WebView.loadUrl() -

-

before load url on webview want set value inside browser localstorage.

till way did managed set value after page loaded. how can set value:

browser.setwebviewclient(new webviewclient() {          @override         public void onpagefinished(webview view, string url) {                 loadurl("javascript: localstorage.set('namespace', 'key', 'value');");         } }

i did try override method onpagestarted(), value not stored.

how can set key/value before call browser.loadurl()? url/page depends on value, need set value before load page.

what can set redirect javascript actual url , load javascript plus redirect using webview.loaddata().

 string injection = "<html><head><script type='javascript'>localstorage.set('namespace', 'key', 'value');window.location.replace('your_url_here');</script></head><body></body></html>";  webview.loaddata(injection, "text/html", null);

be aware though might need save file first before works: see how load javascript redirect android webview?

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
