     WARNING: The specified Android SDK Build Tools version (23.0.1) is ignored, as it is below the minimum supported version (27.0.3) for

My build.gradle file

// Файл сборки верхнего уровня, в который можно добавить параметры конфигурации, общие для всех подпроектов / модулей.

    buildscript {
        ext {
            buildToolsVersion = "27.0.3"
            minSdkVersion = 16
            compileSdkVersion = 27
            targetSdkVersion = 26

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

    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"
            }
        }
    }


    task wrapper(type: Wrapper) {
        gradleVersion = '4.4'
        distributionUrl = distributionUrl.replace("bin", "all")
    }

Я очень новичок в React Native, может кто-нибудь подсказать мне, как это исправить?
