Room Database 之引入依赖

1、在moudule的gradle中的plugins代码中添加如下代码

    id 'kotlin-kapt'

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'kotlin-kapt'
}

2、在moudule的gradle中的android代码块中添加如下代码 

    packagingOptions {
        exclude 'META-INF/atomicfu.kotlin_mudule'
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

3、在module的gradle中添加依赖

  def roomVersion = "2.4.2"

    implementation("androidx.room:room-runtime:$roomVersion")
    annotationProcessor("androidx.room:room-compiler:$roomVersion")



    def roomVersion = "2.4.2"

    implementation("androidx.room:room-runtime:$roomVersion")
    annotationProcessor("androidx.room:room-compiler:$roomVersion")

3、 gradle代码

    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'kotlin-kapt'

        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
