我正在尝试建立一个QR码阅读应用程序。最终目标是创建一个读取QR码的应用程序，然后从数据库中获取相关图像（图像标识号应该存储在QR码中）并将其显示在应用程序中。我正在按照本指南。 https://www.techiediaries.com/reactnative-android-barcode-scanner/
但是构建失败了，这里是堆栈跟踪：
iroshan@debian:/mnt/Data/folio$ cd android && ./gradlew installDebug --stacktrace
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':app:preDebugBuild'.
> Could not resolve all task dependencies for configuration ':app:debugRuntimeClasspath'.
> Could not resolve project :react-native-camera.
Required by:
project :app
> Cannot choose between the following variants of project :react-native-camera:
- generalDebugRuntimeElements
- mlkitDebugRuntimeElements
All of them match the consumer attributes:
- Variant 'generalDebugRuntimeElements':

- Found com.android.build.api.attributes.VariantAttr 'generalDebug' but wasn't required.
- Required com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Aar' and found compatible value 'Aar'.
- Required org.gradle.usage 'java-runtime' and found compatible value 'java-runtime'.
- Found react-native-camera 'general' but wasn't required.
- Variant 'mlkitDebugRuntimeElements':
- Required com.android.build.api.attributes.BuildTypeAttr 'debug' and found compatible value 'debug'.
- Found com.android.build.api.attributes.VariantAttr 'mlkitDebug' but wasn't required.

缺少部分react-native-camera链接，即：
在你的android/app/build.gradle文件中 - defaultConfig字段文件添加：
defaultConfig {
missingDimensionStrategy 'react-native-camera', 'general' // <<add this
}
您的安装不完整，请正确使用手动链接指南。
有时react-native link命令不起作用。
主要是在使用react-native链接进行链接时，根据手动链接指南检查所有文件并正确播放服务版本。要100％肯定。
如果您使用wix的react-native-navigation，那么首先运行react-native链接，此命令将更新几个文件，然后手动检查所有文件并更新挂起的文件。
例如：android / app / src / main / java / com / yourProjectName / MainApplication.java这个文件我们必须手动更新...如果使用（wix）rnn-v2，react-native链接将无法更新此文件
