android - 无法扫描二维码

Question

我在 phonegap android 中开发了 barcodescanner 应用程序。我能够扫描二维码和条形码。但是我无法扫描 this二维条码。是我的错还是代码的错？

function scanCode(){

    var scanner = cordova.require("cordova/plugin/BarcodeScanner"); 

    scanner.scan(
             function(result){
                 alert("Scanned Code: " + result.text 
                 + ". Format: " + result.format
                 + ". Cancelled: " + result.cancelled);

             }, 

             function(error){
                 alert("Scan failed: " + error);
             }
         );
    }

function encodeData(){
    var data = document.getElementById("data").value;
    if (data != ''){
        cordova.plugins.barcodeScanner.encode(
            BarcodeScanner.Encode.TEXT_TYPE, data, 
            function(success){
                alert("Encode success: " + success);
            }, 

            function(fail){
                alert("Encoding failed: " + fail);
            }
        );
    }

    else{
        alert("Please enter some data.");
        return false;
    }
}

那是一个PDF417条形码。看起来 BarcodeScanner 插件对该格式有问题。试试另一个插件，比如这个:
