在Java中執行Phonegap（Cordova 3.3.0）插件

Question

我想知道如何從Java調用phonegap插件，例如調用需要的javascript插件：“ cordova.exec（successCallback，failureCallback，'CallListPlugin'，'list'，params）“

但是，如果我從MainActivity調用它？ 無需瀏覽器？

問候！

您可能需要使用以下命令將上述包導入到主Java文件中：

import com.leafcut.ctrac.CallListPlugin;

之后，您應該可以訪問CallListPlugin任何公共方法，例如：

CallListPlugin.execute(String some_string, JSONArray some_array, CallbackContext some_context);
