Android WebView Custom Error page notes

Demand:

WebView Load H5 page encountered an error, you need to modify the system default page, the use of their own customized pages.

Solutions and Procedures:

1. The first use of Webview.loaddatawithbaseurl is to load a string:

String data= "<a onclick=\" window.history.back () \ "> Page error, click Refresh </a>";

Mwebview.loaddatawithbaseurl ("", Data, "text/html", "UTF-8", "" ");

There is a problem: because the Android4.4 system has replaced the browser kernel (from WebKit to Chrome), Window.history.back () is experiencing a problem (WebKit is inconsistent with Chrome's back). Therefore, this method needs to be modified.

2. Then try the following code:

String data= "<a onclick=\" window.location.replace (\ ' "+failingurl+" \ ') \ "> Page error, click Refresh </a>";

Mwebview.loaddatawithbaseurl ("", Data, "text/html", "UTF-8", "" ");

There is a problem: This method avoids the Window.history.back method, but when the user clicks "Refresh" and then backs back the page, it returns to the error page.

3. The final choice:

String data= "<a href=\" javascript:location.reload () \ "> Page error, click Refresh </a>";

Webview.loadurl ("javascript:document.body.innerhtml=\" "+ sb.tostring () +" \ "");

Use innerHTML page does not occur jump, so directly call JS Reload method can, both evade the History.back method, the user will not return to the error page again
