我应该用什么代替“插件”为Phonegap 2.9？ [英] What am I supposed to use in place of "Plugin" for Phonegap 2.9?

问题描述

我正在尝试为表示我应该使用CordovaPlugin，但Eclipse似乎喜欢甚至更少：

我不知道这是否是WebIntent对我失败的原因，但它似乎是一个很可能的嫌疑人。清除这个文件的任何错误怎么办？

另外，我不知道这是否相关，但代码中有另一行触发另一个depracated警告：

所以可能是WebIntent需要一些更一般的修复或某些东西。

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，都将不胜感激。

更新：我尝试使用CordovaPlugin编辑代码，但我仍然收到错误。

我收到错误的行是：

解决方案

你正在使用Phonegap 2.9，所以插件需要是CordovaPlugin。

但是如果你看到，两者的返回类型是不同的。 插件期望返回为PluginResult实例，其中CordovaPlugin将返回值作为布尔值，并使用CallbackContext实例触发回调。某些东西像

  callbackContext.success（Message：OK）; 
  

或

  callbackContext.error（Expected one non-empty string argument。）; 
  

您可以深入了解这里的文档，http://docs.phonegap.com/en/2.9.0/guide_plugin-development_android_index .md.html＃开发％20a％20插件％20on％20Android

I am trying to implement the WebIntent plugin for Phonegap as part of my Android app.

I have downloaded the latest version of WebIntent, within this week, and it has not been updated for about half a year, so I think it is as up to date as possible. I am using version 2.9 of Phonegap.

WebIntent is not working for me, and in my Eclipse interface, it says that the class "Plugin" is deprecated:

This answer here on Stack Overflow indicates that I should use "CordovaPlugin" instead, but Eclipse seems to like that even less:

I'm not sure if this is the reason WebIntent is failing for me, but it looks to be a very likely suspect. What do I do to clear this file of any errors?

Also, I don't know if this is related, but there is another line in the code that triggers another "depracated" warning:

So it may be that WebIntent needs some more general fix or something.

In any case, I just want to get WebIntent working. Advice on how to do that, whether it involves fixing this Plugin error or not, would be most appreciated.

Update: I have tried to edit the code using "CordovaPlugin", but I am still getting errors.

解决方案

If you are using Phonegap 2.9, so the "Plugin" needs to be "CordovaPlugin".

But if you see, the return type of both are different. "Plugin" expects return as a "PluginResult" instance, where as "CordovaPlugin" expects return as a boolean value, and the callback is triggered using "CallbackContext" instance. some thing like

callbackContext.success("Message : OK");

or

callbackContext.error("Expected one non-empty string argument.");

You can have a deep look into this over the docs here http://docs.phonegap.com/en/2.9.0/guide_plugin-development_android_index.md.html#Developing%20a%20Plugin%20on%20Android
