如何初始化CordovaInterface类以使用其api并从cordova android插件返回数组或其他集合元素类型？

Question

这是一段我自己搞砸的代码。

public PluginResult execute(String action, JSONArray args, String callbackId)
    {
        PluginResult.Status status = PluginResult.Status.OK;
        String result = "";


        if (action.equals("sayCordova")) 
        {
            Context context = cordova.getActivity().getApplicationContext(); //Initializing cordova to enjoy its method of getApplication Context but i am not getting how to do so.

            TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); 
            number = tm.getLine1Number();

            if(number.length() !=0 && number == null)
            {
                System.out.println("Context is "+context+" NO. :: "+number);
                result=number;
                return new PluginResult(status, result);
            }
            result="No Number found!!!";
            return new PluginResult(status, result);
        }
        result="Issue with Action data";
        return new PluginResult(status, result);
    }

我的问题是：

如何初始化和实例化cordova android插件，以便我可以使用它的方法？

有一种简单的方法可以执行此操作：

@Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException 
    {
        if ("sayCordova".equals(action))
        {
            TelephonyManager tm = (TelephonyManager) this.cordova.getActivity().getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE); 
            number = tm.getLine1Number();

            callbackContext.success(number);
            return true;
        }

        callbackContext.error("Invalid action "+number);
        return false;
    }
