plugins - Phonegap - 更新されたバージョン pg-plugin-screen-orientation?

Question

プラグイン リンク: pg-plugin-screen-orientation

更新しようとしましたが、まったく機能しません。これが私の更新されたバージョンです（Java）：

package com.tsukurusha.phonegap.plugins;

import org.json.JSONArray;
import android.app.Activity;
import android.content.pm.ActivityInfo;

import org.apache.cordova.api.CordovaPlugin;
import org.apache.cordova.api.PluginResult;

public class ScreenOrientation extends CordovaPlugin {
    // Refer to http://developer.android.com/reference/android/R.attr.html#screenOrientation

    private static final String UNSPECIFIED = "unspecified";
    private static final String LANDSCAPE = "landscape";
    private static final String PORTRAIT = "portrait";
    private static final String USER = "user";
    private static final String BEHIND = "behind";
    private static final String SENSOR = "sensor";
    private static final String NOSENSOR = "nosensor";
    private static final String SENSOR_LANDSCAPE = "sensorLandscape";
    private static final String SENSOR_PORTRAIT = "sensorPortrait";
    private static final String REVERSE_LANDSCAPE = "reverseLandscape";
    private static final String REVERSE_PORTRAIT = "reversePortrait";
    private static final String FULL_SENSOR = "fullSensor";

    public PluginResult execute(String action, JSONArray args, String callbackId) {
        if (action.equals("set")) {
            String orientation = args.optString(0);
            Activity activity = (Activity)this.cordova.getActivity();
            if (orientation.equals(UNSPECIFIED)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
            } else if (orientation.equals(LANDSCAPE)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            } else if (orientation.equals(PORTRAIT)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            } else if (orientation.equals(USER)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER);
            } else if (orientation.equals(BEHIND)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_BEHIND);
            } else if (orientation.equals(SENSOR)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
            } else if (orientation.equals(NOSENSOR)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
            } else if (orientation.equals(SENSOR_LANDSCAPE)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
            } else if (orientation.equals(SENSOR_PORTRAIT)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
            } else if (orientation.equals(REVERSE_LANDSCAPE)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
            } else if (orientation.equals(REVERSE_PORTRAIT)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
            } else if (orientation.equals(FULL_SENSOR)) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
            }
            return new PluginResult(PluginResult.Status.OK);
        } else {
            return new PluginResult(PluginResult.Status.INVALID_ACTION);
        }
    }
}

JS ファイル:

var screenOrientation = function() {}
    screenOrientation.prototype.set = function(str, success, fail) {
    cordova.exec(success, fail, "ScreenOrientation", "set", [str]);
};
navigator.screenOrientation = new screenOrientation();

スクリプトを実行してもエラー メッセージはまったく表示されないため、何が問題なのかわかりません。助けてくれてありがとう。
