Learn Couchbase Lite with Kotlin and Jetpack Compose

In this training you will be reviewing an Android Application written in Kotlin and JetPack Compose that uses the Couchbase Lite Android SDK for Kotlin. You will learn how to get and insert documents using the key-value engine, query the database using the QueryBuilder engine or SQL++, and learn how to sync information between your mobile app and Couchbase Capella with App Services.


To run this prebuilt project, you will need:

  • Familiarity with building Android Apps with Kotlin, JetPack Compose, and Android Studio
  • Android Studio Chimpmuck or above
  • Android SDK installed and setup (> v.32.0.0)
  • Android Build Tools (> v.32.0.0)
  • Android device or emulator running API level 23 or above
  • JDK 11 (now embedded into Android Studio 4+)

Installing Couchbase Lite Framework

  • src/build.gradle already contains the appropriate additions for downloading and utilizing the Android Couchbase Lite dependency module. However, in the future, to include Couchbase Lite support within an Android app add the following within the Module gradle file (src/app/build.gradle)

allprojects {
    repositories {

        maven {
            url "https://mobile.maven.couchbase.com/maven2/dev/"

Then add the following to the app/build.gradle file.

dependencies {

    implementation "com.couchbase.lite:couchbase-lite-android-ktx:3.0.2"

For more information on installation, please see the Couchbase Lite Documentation.

Demo Application




The demo application uses application architecture concepts in developing modern Android applications recommended by the Android development team.

Koin, the popular open-source Kotlin based injection library, is used to manage dependency inversion and injection. Using Koin we can use JDK 11 versus Hilt or Dagger, which requires JDK 8.

The application structure is a single Activity that uses JetPack Compose to render the multiple compose-based views. In addition, the Navigation Graph is used to handle routing and navigation between various views.

The Database Provider is a custom class that manages the database state and lifecycle. Querying and updating documents in the database is handled using the repository pattern. ViewModels will query or post updates to the repository and control the state of objects that the compose-based Views can use to display information.

Application Flow
