（1）打包总是出错，按下面解决方法ok
Open plugins/cordova-plugin-barcode-scanner/plugin.xml and delete all records xmlns:android=""
Open platforms/android/android.json and delete all xmlns:android=\"\"
Do the same in platforms/android/AndroidManifest.xml
（2）alert scanning failed:write settings:false，把targetSdkVersion从原来的25改成22
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="22" />
