Solution 1

For latest Cordova (4+) this a setting in config.xml:

e.g.

<preference name="LoadUrlTimeoutValue" value="70000"/>

Increases default timeout to 70 seconds (default is 20), reducing the chance of timing out.

Docs: https://cordova.apache.org/docs/en/latest/config_ref/index.html#preference

When loading a page, the amount of time to wait before throwing a timeout error.

Solution 2

This may asked here many times.. This issue can fix by adding a timeout to the webview call (index.html). In your project_name.java class just add this

 super.setIntegerProperty("loadUrlTimeoutValue", 5000);

And in Cordova latest, just use this to timeout

 super.loadUrl(Config.getStartUrl(), 5000);

UPDATE :

One more solution, try this

Create a main.html and put your code there, and in your index.html just redirect to main.html

<script>
 window.location='./main.html';
</script>

Solution 3

This blog post from Robert Kehoe:

Seemed to be EASY to me
Made sense to me
WORKED for me

Rename your index.html to "main.html"

Create a new "index.html" and put the following content into it:

<!doctype html>
<html>
  <head>
   <title>the title</title>
   <script>
     window.location='./main.html';
   </script>
  <body>
  </body>
</html>

Rebuild your app! No more errors!

Robert also said,

Another good idea is to give your application a “splash screen”, so that the user gets instant feedback that your app is loading/working, before it is fully ready.

Solution 4

The main problem for this issue is take more time to load your page.

yes it's can a hack to solve this issue, make a html page name index.html and your existing index page name to be change as a main.html or any other one give a redirection to this page like this

    <script>
       window.location='main.html';
    </script>

am sure it's work very much

This one solved my problem for the latest version of Cordova. Much more simple than other workarounds.

In my case, it's the splash screen that's timing out. :-(
