Javascript 使用cordova的android Hello world插件

我正在尝试使用Cordova为android构建hello world插件。项目运行时没有错误，但我无法确定结果。我的logcat返回错误

添加插件时出错。这是我的代码

Javascript

window.func = function(str,callback){
            alert("Outside Call Working");
            cordova.exec(callback, function(err){alert(err)},"HelloPlugin","echo", [str]);
        }
        function callPlugin(str){
            alert("JS Working");
            window.func(str,function(){
                alert("Done!");
            });
        } 

安卓

public class HelloPlugin extends CordovaPlugin{

     @Override
        public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
            if(action.equals("echo")){
                String message = args.getString(0); 
                callbackContext.success(message);
                return true;
            }
            callbackContext.success(action);
            return true;
        }     
}

应改为：

cordova.exec(callback, function(err){alert(err)},"org.apache.cordova.plugin.HelloPlugin","echo", [str]);

还可以将您的xml条目更改为：

<plugin name="HelloPlugin" value="com.example.plugintest.HelloPlugin" />


@Root这是另一个问题，但现在添加了您的插件。我无法理解找不到哪个类这是我的logcat返回的
调用未知插件org.apache.cordova.plugin.HelloPlugin“
您的xml条目是什么？再次
找不到类
：）
<plugin name="HelloPlugin" value="com.example.plugintest.HelloPlugin" />
