Point your Firebase Android SDK at Lark by passing your Lark URL to FirebaseDatabase.getInstance(). Everything else (listeners, writes, queries) works without changes.

​
Setup

Add the Realtime Database dependency to your module’s build.gradle: 
dependencies {
    implementation 'com.google.firebase:firebase-database'
}

​
Connect to Lark

Pass your Lark URL when getting the database instance: 
import com.google.firebase.database.FirebaseDatabase

// Change this from https://PROJECT_ID.firebaseio.com
val database = FirebaseDatabase.getInstance("https://your-lark-project-id.larkdb.net")
val myRef = database.getReference("players/alice")
If your google-services.json already has the databaseURL field, you can update it there instead and use FirebaseDatabase.getInstance() without arguments.

​
Project settings

Before connecting, make sure your Lark project is configured correctly:
  1. Allow Legacy Firebase must be enabled in your Lark project settings. This turns on the Firebase wire protocol.
  2. If your Firebase app stores many independent data silos under path prefixes (game rooms, workspaces, etc.), see Database routing for options on splitting them into separate Lark databases.
