 Caused by: java.lang.IllegalStateException: Cannot access database on the main thread since it may potentially lock the UI for a long period of time.

在這使用Kotlin 建立Room資料庫時發生問題

不允許我們在主線程建立

於是我們需要

coroutines

在專案build.gradle(:app) dependencies中加入這兩段

    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.0"
}
