为 android 构建应用程序时用于 cameraview 的多个文件反应本机
Multiple files for cameraview while build app for android react native
我在我的项目中使用 react-native-camera 和 expo-camera。除此之外，我还使用了一些 firebase 功能。
应用程序在 iOS 上运行良好，但在 Android 上运行良好。
删除 firebase 类 后，我可以在模拟器中正确地 运行 应用程序。创建 apk 时，出现以下错误。
我必须从 react-native-camera 中排除这个组，但我使用的是最新的 react-native 版本。因此，它使用的是自动链接，并且未在 build.gradle.
中实现

在 android/app/build.gradle 中的 Firebase 依赖项之后添加这些行：
implementation (project(':react-native-camera')) {
exclude group: "com.google.android.cameraview"

不得不用 expo-camera 替换 react-native-camera。现在一切正常。

在 android/app/build.gradle 中的 Firebase 依赖项之后添加这些行：
implementation (project(':react-native-camera')) {
exclude group: "com.google.android.cameraview"
}
不得不用 expo-camera 替换 react-native-camera。现在一切正常。
