build.gradle Module value is the default content of android studio 3.4.2
build.gradle project value is the default content of android studio 3.4.2

要解决此问题，您需要检查以下步骤：

1-确保您的gradle.build（Project）包含：

  allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {
            url 'http://maven.google.com'
        }

    }
}

2-和build.gradle（module）在依赖项中包含此行：

implementation "com.android.support:support-core-utils:28.0.0"
