implementation 'com.android.support:appcompat-v7:27.1.1'

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "greetgalleryfree.binarycrust.com"
        minSdkVersion 18
        targetSdkVersion 27

    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

apply plugin: 'com.google.gms.google-services'

将此添加到构建的最后。Gradle（模块：应用程序）：

resolutionStrategy.eachDependency { DependencyResolveDetails details ->
    def requested = details.requested
    if (requested.group == 'com.android.support') {
        if (!requested.name.startsWith("multidex")) {
            details.useVersion '27.1.1'
        }
     }

   }
}

请确保您将“27.1.1”替换为您想要用于所有依赖项的android支持库的版本，它不应低于您的Compille sdk版本
