Application Error - The connection to the server was unsuccessful. (file:///android_asset/www/index.html)

In your config.xml file add this line:

<preference name="loadUrlTimeoutValue" value="700000" />

As you said, there are many duplicate questions on the same topic. Any how explaining your situation.

The problem might be solved by adding a timeout to call your index.html

ie you need to add super.setIntegerProperty("loadUrlTimeoutValue", 70000); in your activity.java file ( inside src/com/yourProj/--/youractivity.java) above this line: super.loadUrl("file:///android_asset/www/index.html");

Explanation:

This can be happened due to the following reasons

The core reason: the problem is likely due to the speed of the emulator so the network is too slow complete the communication in a timely fashion.

This can be due to:

  1. Your code/data/image is of too much of size ( I guess in your case you are using some images ,as you said you made some UI modifications, may be the size of images are high)
  2. Your script may have a infinite or long loop, so that it takes too much of time to load.
  3. You will be using too much of scripts (jQuery, iscroll, etc etc.. more number of plugins or scripts )

Here is the working solution

create a new page main.html

example: 

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

change the following in mainactivity.java

super.loadUrl("file:///android_asset/www/index.html");

to

super.loadUrl("file:///android_asset/www/main.html");

Now build your application and it works on any slow connection

refernce.

NOTE: This is a workaround I found in 2013.
