next open build.gradle(Module:app) and add this two lines to existing dependencies

For Java

def room_version = "1.1.0"
implementation "android.arch.persistence.room:runtime:$room_version"
annotationProcessor "android.arch.persistence.room:compiler:$room_version"

For Kotlin

paste this line outside of the dependencies or android scope at the top where kotlin plugins are applied

apply plugin: 'kotlin-kapt'

add this lines to dependencies

def room_version = "1.1.0"
implementation "android.arch.persistence.room:runtime:$room_version"
kapt "android.arch.persistence.room:compiler:$room_version"

to keep yourself updated with the recent dependencies version visit mvn repository for room

here you will find the latest version.
