你好，我從Udacity下面的材料設計課程，當我下載他們在課程中提供的代碼，但是當我在Android中打開它時，它給了我那個錯誤

Answer 1

檢查您的項目您的build.gradle文件的Android工作室的版本相匹配。該項目可能是爲舊版Android Studio編寫的。

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.3' 

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

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