已尝试操作 #

• 执行./gradlew cleanBuildCache清理构建缓存
• 重新安装项目依赖
• 重新执行react-native run-android构建

解决方案 #

1. 明确配置项目根Gradle的扩展参数 #

打开项目根目录的android/build.gradle，在buildscript块中添加或完善ext配置，确保包含compileSdkVersion、kotlinVersion等参数，适配React Native 0.72.4的要求：

buildscript {
    ext {
        buildToolsVersion = "33.0.0"
        minSdkVersion = 21
        compileSdkVersion = 33
        targetSdkVersion = 33
        kotlinVersion = "1.8.0"
    }
    // ... 其他原有内容（repositories、dependencies等）
}

该配置会被react-native-safe-area-context的build.gradle读取，解决compileSdkVersion未指定的问题，同时统一Kotlin版本。

2. 修复Kotlin与Gradle插件兼容性 #

• React Native 0.72.4对应的Android Gradle插件版本为7.4.2，确保根项目android/build.gradle中的com.android.tools.build:gradle版本与之一致，避免版本冲突：

  dependencies {
      classpath("com.android.tools.build:gradle:7.4.2")
      // ... 其他依赖
  }
  

• 确保本地安装的Kotlin版本与配置的kotlinVersion一致，或允许Gradle自动下载对应版本（需网络正常）。

3. 彻底清理缓存并重构 #

1. 删除以下目录：
   • 项目根目录的node_modules
   • android/.gradle、android/build、android/app/build
2. 执行npm install重装依赖
3. 进入android目录执行./gradlew clean
4. 重新执行react-native run-android
