PhoneGap类未找到错误在android [英] PhoneGap class not found error in android

问题描述

我在使用PhoneGap（Android）应用程式时遇到问题。到目前为止我明白了，我做了一切好。这是我做的。

1. 在Eclipse中创建项目后，我在我的libs文件夹中添加cordova-2.2.0.jar


2. 然后我编辑了AndroidManifest.xml和MainActivity.java


3. 我在assets文件夹中创建了www文件夹，并保留cordova-2.2.0.js index.html

所以，一切顺利。但是当我运行这个程序，它显示一个错误。我附上了一个截图和示例代码。

I am facing some problem with my PhoneGap(Android) application. So far I understand, I have done everything well. Here is what I have done.

After creating a project in Eclipse, I have added cordova-2.2.0.jar in my libs folder.
Then I edited AndroidManifest.xml and MainActivity.java
I created www folder inside assets folder and keep cordova-2.2.0.js and index.html
So, far everything was OK. But when I run this program, it is showing an error. I have attached a screenshot and sample code.

解决方案
I was having same issue before. I have just follow below steps and it starts working :


Go to Selected project's Properties
Go to java build path
Select 'Order and Export'
Enable all the checks (dependent projects)
Now just clean and run application again.


It works for me...
