我想弄清楚为什么它在过去几个小时没有运气的情况下无效.我是最新的手机,所以如果我遗失了什么让我知道......

PS.Phonegap -version:3.0.0-0.14.3,设备sdk 8,AVD sdk 8(两个结果相同)

将代码包装在try catch中后更新我收到此错误消息:

result of expression 'navigator.notification' undefined is not an object

在PhoneGap示例应用程序中提到的Android无法正常工作和 navigator.notification.*失败"navigator.notification [undefined]不是一个对象"

原因是:Likely the name of phonegap*js or cordova*js in your index.html does not match the file name in the assets/www directory.但我在platform/android/assets/www中只有phonegap.js和cordova.js,而且我的名字也完全相同......仍然无法弄明白...

UPDATE

如果我进行远程构建,应用程序可以正常使用本地构建它没有;但是我已经安装了版本3中提到的插件

我使用Cordova CLI 3.0.9使用命令行工具构建了您的项目,并遵循此处列出的文档(http://cordova.apache.org/docs/en/edge/cordova_notification_notification.md.html#Notification).我使用了你的HTML和JS代码,弹出的对话框很好.

浏览其他文件时,我注意到了差异config.xml; 我config.xml看起来像这样:

<?xml version='1.0' encoding='utf-8'?>

请注意,我的org.apache.cordova.dialogs.Notification - dialogs由于某些原因你的名字命名空缺了.这是故意的吗？如果添加"对话框"命名空间,它是否有效？如果使用最新的CLI版本重建,该怎么办？
