React Native集成react-native-camera后Android构建失败求助

问题分析 #

报错核心为react-native-async-storage与react-native-camera的属性配置冲突，构建时无法找到匹配的依赖配置项。

解决方案 #

• 安装兼容版本的react-native-camera
  React Native 0.64.0需搭配特定版本的react-native-camera才能避免依赖冲突，执行以下命令安装兼容版本：

  npm install react-native-camera@3.44.3 --save
  

• 添加依赖属性过滤配置
  打开项目根目录下的android/build.gradle，在allprojects的subprojects块中加入以下配置：

  subprojects {
      afterEvaluate { project ->
          if (project.hasProperty("android")) {
              android {
                  if (project.name == "react-native-async-storage_async-storage") {
                      variantFilter { variant ->
                          def names = variant.flavors*.name
                          if (names.contains("general")) {
                              setIgnore(true)
                          }
                      }
                  }
              }
          }
      }
  }
  

• 清理缓存并重新构建
  执行以下命令清理gradle缓存后重新编译项目：

  cd android
  ./gradlew clean
  cd ..
  npm run android
  

• 验证settings.gradle配置
  确认settings.gradle中已正确引入两个模块：

  include ':react-native-camera'
  project(':react-native-camera').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-camera/android')
  include ':react-native-async-storage_async-storage'
  project(':react-native-async-storage_async-storage').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-async-storage/async-storage/android')
