      Description — How to install Couchbase Lite on Android
      Abstract — Getting you up and running quickly with Couchbase Lite on android

      Introduction

      Couchbase Lite on Android supports the development of applications in Java or Kotlin.

      You can install Couchbase Lite Community and-or Enterprise editions from the Maven repository. There are separate downloads for Kotlin and Java.

      Enterprise users can also download the Couchbase Lite Vector Search extension library. Installation instructions are included in the step-by-step install guides for both Java and Kotlin.

      Couchbase Lite Quick Steps

      For experienced developers, this is all you need to add _Couchbase Lite for Android 3.2.0 to your application projects.

      Kotlin - Enterprise

      1. Create a Kotlin Android app project in Android Studio

      2. Add Couchbase Lite as a dependency in your app-level build.gradle
        implementation 'com.couchbase.lite:couchbase-lite-android-ee-ktx:3.2.0'

      3. Add the following maven repo to your repositories (in build.gradle or settings.gradle as required
        https://mobile.maven.couchbase.com/maven2/dev/

        1. If you want to use Vector Search, add the Couchbase Lite Vector Search dependency for architectures other than x86_64: com.couchbase.lite:couchbase-lite-java-vector-search-arm64-1.0.0

          1. For x86_64 architectures: com.couchbase.lite:couchbase-lite-android-vector-search-x86_64-1.0.0

        2. You must then use CouchbaseLite.enableVectorSearch(); to enable the vector search extension.

      4. Build the project and it will pull Couchbase Lite down.

      Kotlin - Community

      3. Check you have mavenCentral() in repositories (or in settings.gradle)

      4. Build the project and it will pull Couchbase Lite down.

      Java - Enterprise

      1. Create a Java Android app project in Android Studio

      2. Add Couchbase Lite as a dependency in your app-level build.gradle
