我正在使用HTML5，JavaScript和IDE（eclipse）构建混合Android应用程序。
在我的应用中，我制作了两个html页面。一个是index.html，另一个是camera.html。
[index.html的]

我添加的index2.js通常在主页面（index.html）中运行，并通过按钮移动到camera.html页面，问题是没有尝试使用Camera功能。
所有JavaScript来源都无法在camera.html中使用。
我猜是Cordova-Whitelist是个问题。还是有其他问题吗？
混合应用程序开发不是第一次使用。希望得到很多帮助。

当我触摸我的应用程序中的“捕捉照片”按钮时，此图像是错误日志。
