解決這個問題再gradle（project）目錄新增

ext {
    supportlib_version = '26.1.0'
}
subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex')) {
                details.useVersion "$supportlib_version"
            }
        }
    }
}
