在Cordova CLI中使用插件

Question

I'm using Cordova CLI (v6.0.0) to make an app for Android and I can't load the plugins: cordova-plugin-file and cordova-plugin-dialogs. I know it because the next alerts are shown:

if (!navigator.notification)
    alert("Plugin notification not working properly!");

if (!window.requestFileSystem)
    alert("Plugin file not working properly!");

Plugins are used after clicking a button (not before ondeviceready event). Plugins have been installed with:

cordova-plugin-file v.1.2.0

 cordova plugin add cordova-plugin-file 

cordova-plugin-dialogs v4.1.0

 cordova plugin add cordova-plugin-dialogs

I've also added the next line in config.xml

<preference name="AndroidPersistentFileLocation" value="Compatibility" />

What I'm doing wrong?

主html文件中的下一行丢失了：

<script type="text/javascript" src="cordova.js"></script>
