As you said, there are many duplicate questions on the same topic. Any how explaining your situation.
正如您所说，同一主题有许多重复的问题。任何如何解释你的情况。
The problem might be solved by adding a timeout to call your index.html
可以通过添加超时来调用您的 index.html 来解决该问题
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");
即你需要super.setIntegerProperty("loadUrlTimeoutValue", 70000);在你的 activity.java 文件（在 src/com/yourProj/--/youractivity.java 中）添加到这一行上面： super.loadUrl("file:///android_asset/www/index.html");
Explanation:
解释：
This can be happened due to the following reasons
这可能是由于以下原因造成的
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.
核心原因：问题很可能是由于模拟器速度太慢导致无法及时完成通信。
This can be due to:
这可能是由于：
- 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)
- Your script may have a infinite or long loop, so that it takes too much of time to load.
- You will be using too much of scripts (jQuery, iscroll, etc etc.. more number of plugins or scripts )
- 您的代码/数据/图像太大了（我猜在您的情况下您正在使用一些图像，正如您所说，您进行了一些 UI 修改，可能是图像的尺寸很大）
- 您的脚本可能有一个无限循环或长循环，因此加载时间太长。
- 您将使用过多的脚本（jQuery、iscroll 等。更多的插件或脚本）

Here is the working solution
这是工作解决方案
create a new page main.html
创建一个新页面 main.html
example:
例子：
<!doctype html>
<html>
<head>
<title>tittle</title>
<script>
window.location='./index.html';
</script>
</head>
<body>
</body>
</html>
change the following in mainactivity.java
在 mainactivity.java 中更改以下内容
super.loadUrl("file:///android_asset/www/index.html");
to
到
super.loadUrl("file:///android_asset/www/main.html");
Now build your application and it works on any slow connection
现在构建您的应用程序，它适用于任何慢速连接
参考。
NOTE: This is a workaround I found in 2013.
注意：这是我在 2013 年发现的一种解决方法。

I had a similar issue and based on above suggestions I first added "super.setIntegerProperty("loadUrlTimeoutValue", 70000);" but that did not help. So I tried Project -> Clean, that worked and I can launch the app now !

Extending loading Timeout Limit will not solve the problem which caused the error, it just will avoid the system to show the message but performance will be affected whatsoever.
延长加载超时限制不会解决导致错误的问题，它只会避免系统显示消息但性能会受到任何影响。
Actual reason: You may be linking files or images to remote locations, and those resources are taking too long to load. (this is likely the most common error)
实际原因：您可能将文件或图像链接到远程位置，而这些资源加载时间过长。（这可能是最常见的错误）
Definitive solution: move all the scripts, images and css needed to some local folders and load them locally ...
最终解决方案：将所需的所有脚本、图像和 css 移动到某些本地文件夹并在本地加载它们...
Performance will be increased and error will be effectively solved.
性能将得到提高，错误将得到有效解决。

Check you index.htmlfile. If you use external resources, that not available when you run application then you can get this error.
检查你的index.html文件。如果您使用运行应用程序时不可用的外部资源，则可能会出现此错误。
In my case I forgot to delete link on debugger script (weinre).
就我而言，我忘记删除调试器脚本（weinre）上的链接。
<script src="http://192.168.0.102:8080/target/target-script-min.js#anonymous"></script>
So application worked on emulator because http://192.168.0.102:8080/was on my localhost and available for emulator.
所以应用程序在模拟器http://192.168.0.102:8080/上工作，因为它在我的本地主机上并且可用于模拟器。
But when I setup application on mobile phone I had same error, because 192.168.0.102 was not available from mobile network.
但是当我在手机上设置应用程序时，我遇到了同样的错误，因为 192.168.0.102 无法从移动网络获得。
