java - 包构建不存在 "Build.VERSION.SDK_INT"

Question

我想使用此存储库来创建 react native 应用程序，而不是可以在前台和后台运行，但是当我下载此存储库并想要使用它时，我收到此错误:

Task :app:compileDebugJavaWithJavac FAILEDC:\Users\PC\Desktop\shem\rn-heartbeat-master\android\app\src\main\java\com\rnheartbeat\BootUpReceiver.java:11: error: package Build does not existif (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

这是我的基础设施:

Operating system: Windows 10 10.0Max Gradle workers: 12 workers
Java runtime: Oracle Java(TM) SE Runtime Environment 12.0.2+10
Java VM: Oracle Java HotSpot(TM) 64-Bit Server VM 12.0.2+10 (mixed mode, sharing)

我的build.gradle:

ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
    }

我的package.json:

"dependencies": {
    "react": "16.9.0",
    "react-native": "0.61.0",
    "react-redux": "^7.0.3",
    "redux": "^4.0.1",
    "redux-actions": "^2.6.5"
  }

Answer 1

将 import android.os.Build; 添加到 BootUpReceiver.java
