我正在尝试构建我的react-native应用程序，但它返回此错误：

我的build.gradle文件具有：

android.useAndroidX=true
android.enableJetifier=true

我的app / build.gradle文件具有：

implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"

我也尝试过：

implementation "com.android.support:appcompat-v7:28.+"

在Android Studio中打开项目，“迁移到AndroidX”按钮不会出现。

我在做什么错了？

对不起，我是Java的新手，对如何处理它一无所知：（

这是我的build.gradle文件

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "27.0.3"
        minSdkVersion = 23
        compileSdkVersion = 28
        targetSdkVersion = 26
        supportLibVersion = "28.0.0"
        playServicesVersion = "16.0.0"
    }
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:4.0.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
        maven { url "https://maven.google.com" }
        mavenLocal()
        google()
        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/'
            name 'Google'
        }
        jcenter()
    }
}

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "28.0.0"
            }
        }
    }
    afterEvaluate {
        android {
            compileSdkVersion 28
            buildToolsVersion "27.0.3"

            defaultConfig {
                targetSdkVersion 27
            }
        }
    }
}

ext {
    buildToolsVersion = "27.0.3"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 27
    supportLibVersion = "27.1.0"
}

3 个答案:

答案 0 :(得分：0)

最有可能在未看到build.gradle的情况下迁移了完整版本号：

implementation "com.android.support:appcompat-v7:28.0.0"

答案 1 :(得分：0)

尝试一下

implementation "com.android.support:appcompat-v7:28.0.0"

将28.0.0应用程序兼容转换为androidx之后，因此“ androidx .....：1.0.0”本身就是implementation "com.android.support:appcompat-v7:29.0.0"

support：appcompat不得大于“ 28.0.0”

答案 2 :(得分：0)

Android Studio在菜单栏中提供了一个将现有android项目迁移到Androidx的选项。菜单->重构-迁移到AndroidX
