android - PhoneGap 截图插件不适用于 Android？

Question

我目前在 phonegap android 项目中使用屏幕截图插件(插件版本 2.0.0)，该插件会返回一些错误，例如

未捕获的类型错误:无法调用文件中未定义的方法“saveScreenshot”:///android_asset/www/index.html

我的代码:

 <script src="cordova-2.5.0.js"></script>
 <script src="js/jquery-1.8.1.min.js"></script>
 <script src="js/Screenshot.js"></script>
 <script>
  document.addEventListener("deviceready",onDeviceReady,false);
  function onDeviceReady() {
   $('#screen').click(function(){
   window.plugins.screenshot.saveScreenshot();
  });
 } 
</script>

 <button id="screen">ScreenSave</button>

我做错了什么任何人指导我。
谢谢

这里缺少了很多东西。您需要添加 screenshot.java文件到您的项目并添加对 screenshot.js 的引用在你的 index.html 中。您还需要提供写入本地存储的权限 described here .
