我正在尝试在Phonegap中使用条形码扫描仪插件，但是每当我尝试"phonegap build android"时，我都会收到错误。错误是：
构建在 2 秒内失败 cmd：命令失败，退出代码为 1 错误输出： D：\Projects\Mobile_Apps\apps\inventory-manager\platforms\android\app\src\main\res\xml\config.xml：66： AAPT： error： unbound prefix.
D：\Projects\Mobile_Apps\apps\inventory-manager\platforms\android\app\src\main\res\xml\config.xml：66：错误：未绑定前缀。 D：\Projects\Mobile_Apps\apps\inventory-manager\platforms\android\app\src\main\res\xml\config.xml：错误：文件编译失败。
失败：生成失败，出现异常。
出了什么问题： 任务"：app：mergeDebugResources"的执行失败。 错误：java.util.concurrent.ExecutionException：com.android.tools.aapt2.Aapt2Exception：AAPT2 错误：检查日志以了解详细信息
我将以下代码添加到我的 config.xml 文件中(正如插件说明所说的那样(：
<config-file target="AndroidManifest.xml" parent="/*" mode="merge">
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
</config-file>
我认为这是问题的症结所在，但我不确定出了什么问题或如何解决它，因为如果我把它拿出来，应用程序就会崩溃。
以下是 config.xml 文件(位于项目的根文件夹中(的外观：
<?xml version='1.0' encoding='utf-8'?>

任何帮助将不胜感激！谢谢！！！！
我想通了！我只需要删除我的旧安卓版本，删除我添加到 XML 文件中的代码，然后重建应用程序！但是，当我启动应用程序并尝试使用扫描仪时，它会打开设置并询问我是否要允许该应用程序更改系统设置。如果我选中"是"，扫描仪可以工作，但会短暂返回错误。一个小错误，我需要在某个时候修复。如果您有任何解决此问题的建议，请告诉我。谢谢！
