Answer 2

I face the same problem while I have updated my SDK and Android studio version(3.0 beta). I have solved this problem going through this tutorial. In this they told us to update are build configuration file like

android {
   compileSdkVersion 26
   buildToolsVersion '26.0.0'
   defaultConfig {
   targetSdkVersion 26
  }
  ...
}

dependencies {
   compile 'com.android.support:appcompat-v7:26.0.0'
}

// REQUIRED: Google's new Maven repo is required for the latest
// support library that is compatible with Android 8.0
repositories {
   maven {
       url 'https://maven.google.com'
       // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
   }
}

Hope it will help you out.

Answer 3

There is another way to add google repository

1. Add gradle-4.1-rc-1-all in gradle-wrapper.properties.

   distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip
   

2. Then add google() in the top-level build.gradle

   allprojects {
     repositories {
       google()
       jcenter()
     }
   }
   

Answer 4

Clean your gradle from terminal

./gradlew clean

then use this code in your build.gradle section

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

Make sure, your included library version is available. For your checking, you can use this link
