Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src

在html编写之前，先在终端下载好cordova-file插件，同时注意开起真机设备的或模拟器的 文件存储权限，具体路径为：设置-->应用管理->高级 ->应用权限->存储, 这个要千万注意，不然打不开sdk内容。
