Answer 1

Nó thường là một vấn đề với kho lưu trữ của bạn trong tệp gradle của bạn.

cho tôi làm việc để thay đổi build.gradle như thế này:

buildscript { 
    repositories { 
     mavenLocal() 
     google() 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:3.0.1' 
    } 
} 

vì vậy khi bạn thêm google() nó sẽ làm việc.

Answer 2

buildscript { 
    repositories { 
     jcenter() 
     google() 
     mavenCentral() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:3.0.1'  
    } 
} 

Thêm google() bên trong buildscript() và Dự án đồng bộ hóa.
