1.遇到这个问题不要急很简单

解决方法

在这个路径…/android/build.gradle (不是这个路径…/android/app/build.grade) 添加如下配置：

subprojects {
    project.configurations.all {
    resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'androidx.core' &&
           !details.requested.name.contains('androidx')) {
        details.useVersion "1.0.1"
            }
    }
    }    
}

2.如果是 Android dependency ‘androidx.androidx.appcompat:appcompat’ has different version for the compile (1.0.0) and runtime (1.0.2) classpath. You should manually set the same version via DependencyResolution

3.则在这个路径…/android/build.gradle 添加

subprojects {
    project.evaluationDependsOn(':app')
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'androidx.appcompat' &&
                    !details.requested.name.contains('androidx')) {
                details.useVersion "1.0.2"
            }
        }
    }
}
