Question

我已经尝试了SO中的现有解决方案，但无济于事。我猜错了。我刚刚在gradle-wrapper.properties中更新了gradle

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

这是我的android / build.gradle

wrapper {
    gradleVersion = '5.1.1'
    distributionUrl = distributionUrl.replace("bin", "all")
}

我的 android / build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
ext {
    googlePlayServicesVersion = "+"
}
buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 27
        targetSdkVersion = 26
        supportLibVersion = "27.1.1"
        googlePlayServicesVersion = "15.0.1"
        googlePlayServicesAuthVersion = "15.0.1"
        firebaseVersion = "16.0.4"
    }
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        // classpath 'com.android.tools.build:gradle:3.1.2' // <--- use this version or newer
        classpath 'com.google.gms:google-services:4.2.0' // <--- use this version or newer
    }
}

allprojects {
    repositories {
        mavenLocal()
        google()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven { url 'https://maven.google.com' }
        maven { url "https://jitpack.io" }
    }
}

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
  }
}

wrapper {
    gradleVersion = '5.1.1'
    distributionUrl = distributionUrl.replace("bin", "all")
}

configurations.all {
    resolutionStrategy {
        force 'com.google.android.gms:play-services-gcm:12.0.1'
   }
}

Android studio gradle文件同步

由于我们在直接发布内容方面存在字符限制，因此我通过要点进行了附加。

Answer 1

我不确定我是否正确。我只是在评论这些行

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
  }
}

工作正常...

Answer 2

在allProjects中移动子项目部分：

allprojects {

{...} //The rest of your config

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
        android {
            compileSdkVersion rootProject.ext.compileSdkVersion
            buildToolsVersion rootProject.ext.buildToolsVersion
        }
    }
    }
}

}

Answer 3

在C驱动器中移动整个React Native项目。在项目内部打开命令行。
cd android
./ gradlew clean
cd ..
react-native run-android

问题可能是您在同一项目文件夹中具有多个React Native项目。

希望它会起作用。

Answer 4

对于RN 0.57，请尝试

classpath 'com.android.tools.build:gradle:3.2.0'

gradleVersion = '4.6'

在此处查看0.57的发行说明：

https://github.com/react-native-community/releases/blob/master/CHANGELOG.md

更新：

对于我使用的RN 0.57.2：

com.android.tools.build:gradle:3.1.4
Android studio 3.1.4
gradle 4.4

对于我使用的RN 0.58.6：

 classpath 'com.android.tools.build:gradle:3.3.0'
 gradleVersion '4.7'
 Android studio 3.1.4

Answer 5

subprojects { project -> 
  afterEvaluate {
        if((project.plugins.hasPlugin('android') || project.plugins.hasPlugin('android-library'))) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

项目'：app'上的Project＃afterEvaluate（Closure）无法在当前上下文中执行。反应本机
