导入相关

1. 根目录的**build.gradle**加入google repository

   allprojects {
       repositories {
           google()  //add google repository
           jcenter()
       }
   }

2. 根目录的**build.gradle**或自定义的gradle文件定义全局版本号：

   ext {
       roomVersion = '2.2.0'
       archLifecycleVersion = '2.2.0-beta01'
       coreTestingVersion = '2.1.0'
       materialVersion = '1.0.0'
       nav_version = '2.1.0'
   }

3. app的**build.gradle**中导入依赖

   // Room components
   implementation "androidx.room:room-runtime:$rootProject.roomVersion"
   annotationProcessor "androidx.room:room-compiler:$rootProject.roomVersion"
   androidTestImplementation "androidx.room:room-testing:$rootProject.roomVersion"
   
   // Lifecycle components
   implementation "androidx.lifecycle:lifecycle-extensions:$rootProject.archLifecycleVersion"
   annotationProcessor "androidx.lifecycle:lifecycle-compiler:$rootProject.archLifecycleVersion"
   
   // navigation
   implementation "androidx.navigation:navigation-fragment:$rootProject.nav_version"
   implementation "androidx.navigation:navigation-ui:$rootProject.nav_version"
   
   // UI
   implementation "com.google.android.material:material:$rootProject.materialVersion"
   
   // Testing
   androidTestImplementation "androidx.arch.core:core-testing:$rootProject.coreTestingVersion"
