【问题描述】：

我说的是这个插件katzer/cordova-plugin-local-notifications

几个月前我用过它。现在我发现它在很多方面都发生了变化。所以我尝试创建一个简单的通知。

我安装了插件

cordova plugins add https://github.com/katzer/cordova-plugin-local-notifications

接下来我尝试了一些简单的方法

alert("enter");    

var now             = new Date().getTime(),
_5_sec_from_now = new Date(now + 5*1000);

cordova.plugins.notification.local.schedule(
    title: "Production Jour fixe",
    text: "Duration 1h",
    at: _5_sec_from_now,

);

alert("exit");  

什么也没发生，没有错误显示。两个警报都完美显示。

然后我尝试了一些更简单的方法。

cordova.plugins.notification.local.schedule( message:"Hello World" );

cordova.plugins.notification.local.get(0, function (notification) 
    alert(notification.text); //=> "Hello World"
    alert(notification.message); //=> undefined
);

再次没有。 Eclipse logcat 正在显示这个

我在 Genymotion 模拟器 4.2.2 设备映像和 Xperia - android 4.4.4 中进行了测试。我一直在等待 deviceready 事件触发。 js中没有其他错误。谁能告诉我我错过了什么？有什么问题吗？

【参考方案1】：

没有找到问题的原因，但这里是解决方案。

这是一个较旧的项目，目标sdk是16，所以我将其更新为19。

重新安装所有插件。它现在正在工作。我猜这是某种依赖/版本错误。使用新的插件版本，它可以按预期工作。

【参考方案2】：

为了我的项目（因为它是一个遗留项目，尽管它指向 sdk 19）我不得不使用 0.7.8 版本，并且 nullPointerException 消失了，一切都开始完美运行。

程序

先删除当前最新版本的插件。

$ phonegap plugin rm de.appplant.cordova.plugin.local-notification

然后安装0.7.8版

$ phonegap plugin add de.appplant.cordova.plugin.local-notification@0.7.8

然后跟着docs for that version

疑难解答

如果您对phonegap plugin rm 有问题，您可以尝试重新安装最新版本并卸载以正确安装 0.7.8。

为了成功安装 0.7.8 版，我必须从 /src 中删除一些 de.applant.cordova.plugin.localnotification 包，以及从 /assets/www/plugins 中删除 js 文件夹 de.appplant.cordova.plugin.local-notification。
