我正在尝试将 Phonegap 的WebIntent 插件实现为我的 Android 应用程序的一部分。
我已经下载了最新版本的WebIntent，在这周内，大约有半年没有更新了，所以我认为它尽可能是最新的。我正在使用 2.9 版的 Phonegap。
WebIntent 对我不起作用，在我的 Eclipse 界面中，它说“插件”类已被弃用：
Stack Overflow 上的这个答案表明我应该改用“CordovaPlugin”，但 Eclipse 似乎更不喜欢这样：
我不确定这是否是 WebIntent 对我来说失败的原因，但它看起来很可能是一个嫌疑犯。我该怎么做才能清除此文件中的任何错误？
另外，我不知道这是否相关，但代码中有另一行触发另一个“已弃用”警告：
所以可能是 WebIntent 需要一些更一般的修复或其他东西。
无论如何，我只想让 WebIntent 工作。关于如何做到这一点的建议，无论是否涉及修复此插件错误，将不胜感激。
更新：我尝试使用“CordovaPlugin”编辑代码，但仍然出现错误。
我遇到错误的行是：
... 和：
这是整个文件：
