我目前正在为phonegap android项目使用截图插件（插件版本2.0.0），该插件返回一些错误，如

未捕获的类型错误：无法在 file:///android_asset/www/index.html 处调用未定义的方法“saveScreenshot”

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>

我做错了什么有人指导我。
谢谢

这里缺少很多东西。您需要将screenshot.java文件添加到您的项目中，并在 index.html 中添加对screenshot.js的引用。此外，您还需要提供写入本地存储的权限，如此处所述。
