我无法让 phonegap 正常工作。phonegap 功能/对象似乎不起作用。即使我使用正确的 CLI 命令包含了插件,并且根据文档确保所有文件都位于正确的位置,推送通知也不起作用。我使用了 PushNotifications 插件文档中的 javascript 代码,所以我认为它也是正确的。
我已经在 Mac OS X 10.8.4 上安装了 PhoneGap,并使用 CLI 界面创建了一个新的 PhoneGap 项目。
然后我为应用程序编写了 HTML/CSS/JavaScript 文件并将它们放在 www 目录中。我使用以下命令在我的 android 设备上构建和运行应用程序:
phonegap local run android
它运行良好,应用程序在我的设备上启动。一切正常。然后我添加了一些使用phonegap的函数/对象的代码,并尝试再次在android上运行它。该应用程序再次运行良好,但这次没有执行以下代码:
alert(device.platform);
此外,由于错误(未定义设备),PushNotifications 代码也没有执行我试图同时包含cordova.js、phonegap.js,甚至都不包含它们,但结果仍然相同.
我检查了项目目录中的platforms/android/assets/www 文件夹是否包含正确的文件,并且确实如此。自动添加了 cordova.js 和 phonegap.js 文件(phonegap build 命令出于向后兼容性的原因添加了这两个文件,至少我是这么理解的)。
所以我试图弄清楚为什么设备对象是未定义的,即使 phonegap.js 文件存在于 www 文件夹中并且包含在 html 文件中。我想如果我能得到“alert(device.platform);” 代码工作,然后推送通知代码也可以工作,因为它在必须评估 device.platform 的 if 语句处失败。
