我正在尝试将Phonegap WebIntent plugin作为我的Android应用的一部分来实现。
我已经在本周内下载了最新版本的WebIntent,并且大约半年没有更新,所以我认为它是尽可能最新的。我使用的是Phonegap的2.9版本。
WebIntent不适用于我,在我的Eclipse界面中,它说不推荐使用“Plugin”类:
This answer表示我应该使用“CordovaPlugin”,但Eclipse似乎更喜欢这样:
我不确定这是否是WebIntent失败的原因,但它看起来很可能是个嫌疑人。如何清除此文件中的任何错误?
另外,我不知道这是否相关,但代码中还有另一行触发了另一个“被删除”的警告:
因此可能是WebIntent需要一些更通用的修复或其他东西。
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,都将非常感激。
更新:我尝试使用“CordovaPlugin”编辑代码,但我仍然遇到错误。
我遇到错误的行是:

答案 0 :(得分:1)
如果您使用的是Phonegap 2.9,那么“插件”必须是“CordovaPlugin”。
但是如果你看到,两者的返回类型是不同的。 “插件”期望返回“PluginResult”实例,其中“CordovaPlugin”期望作为布尔值返回,并使用“CallbackContext”实例触发回调。像
这样的东西callbackContext.success("Message : OK");
或
callbackContext.error("Expected one non-empty string argument.");
