How to import Room Persistence Library to an Android project

Question

I recently saw the new feature announced on Google I/O Room Persistence Library to work with Sqlite databases on Android. I have been looking to the official documentation and I

Answer 1

On your project root build.gradle you have to add Google's maven repository:

allprojects {
    repositories {
        jcenter()
        maven {
            // For Room Persistence Library
            url "https://maven.google.com"
        }
    }
}

And then on the build.gradle of the Module you should add:

compile 'android.arch.persistence.room:runtime:1.0.0-alpha1'
annotationProcessor 'android.arch.persistence.room:compiler:1.0.0-alpha1'
compile 'android.arch.lifecycle:extensions:1.0.0-alpha1'
annotationProcessor 'android.arch.lifecycle:compiler:1.0.0-alpha1'
compile 'android.arch.persistence.room:rxjava2:1.0.0-alpha1'
testCompile'android.arch.persistence.room:testing:1.0.0-alpha1'

Add this if you want to use RxJava2 Publisher and Flowable objects as a result of your queries

compile 'android.arch.persistence.room:rxjava2:1.0.0-alpha1'

And finally add also this dependency to test migrations

testCompile'android.arch.persistence.room:testing:1.0.0-alpha1'

Update: The libraries are still marked as Alpha1 so I guess the version number will be updated soon, maybe using 1.0.+ until there is a final version could be a good idea have been updated and as definded on the documentation you can use room 1.1.1 using this dependencies:

dependencies {
   def room_version = "1.1.1"

   implementation "android.arch.persistence.room:runtime:$room_version"
   annotationProcessor "android.arch.persistence.room:compiler:$room_version" // use kapt for Kotlin

   // optional - RxJava support for Room
   implementation "android.arch.persistence.room:rxjava2:$room_version"

   // optional - Guava support for Room, including Optional and ListenableFuture
   implementation "android.arch.persistence.room:guava:$room_version"

   // Test helpers
   testImplementation "android.arch.persistence.room:testing:$room_version"
}
