在运行app的时候出现这个错误Android dependency 'androidx.core:core' has different version for the compile (1.0.0) and runtime (1.0.2) classpath。
在我们的build.gradle里面添加下面这段代码就行了

    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex') ) {
                    details.useVersion "27.1.1"
                }
                if (details.requested.group == 'androidx.core'
                        && !details.requested.name.contains('androidx') ) {
                    details.useVersion "1.0.2"
                }
            }
        }
    }
