cordova二维码插件BarcodeScanner安装后程序闪退

安装网上的教程，安装cordova,创建项目，安装BarcodeScanner插件，在主页中添加代码

 <a href="#" class="btn" onclick="scanCode();">Scan Code</a>  
<script type="text/javascript">  
function scanCode() {  
    cordova.plugins.barcodeScanner.scan(  
      function (result) {  
          alert("We got a barcode\n" +  
                "Result: " + result.text + "\n" +  
                "Format: " + result.format + "\n" +  
                "Cancelled: " + result.cancelled);  
      },   
      function (error) {  
          alert("Scanning failed: " + error);  
      }  
   );  
}  
</script>  

然后把项目导入到idea中编译，下载到手机上测试，可一点击扫描按钮就会闪退！
