我想知道如何从java调用phonegap插件，例如调用想要的javascript插件：“cordova.exec（successCallback，failureCallback，'CallListPlugin'，'list'，params）”
但是，如果我从MainActivity调用它？没有通过浏览器？
问候！

答案 0 :(得分：0)
您可能希望使用以下命令将上面的包导入主Java文件：
import com.leafcut.ctrac.CallListPlugin;
之后，您应该可以访问CallListPlugin的任何公共方法，例如：
CallListPlugin.execute(String some_string, JSONArray some_array, CallbackContext some_context);
