Krenalis Kotlin SDK

The Krenalis Kotlin SDK lets you send customer event data from your Android applications to your specified destinations.

SDK setup requirements

• Set up a Krenalis account.
• Set up an Android source in the dashboard.
• Copy the write key and the endpoint.

Installation

To integrate the Kotlin SDK inside your application, add the dependency to your build.gradle. Make sure to replace <latest_version> with the latest version of the SDK.

repositories {
  mavenCentral()
}
dependencies {
  implementation 'com.krenalis.analytics.kotlin:android:<latest_version>'
}

Add the required permissions to AndroidManifest.xml (if they are not yet present).

<!-- Required for internet. -->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Using the SDK

import com.krenalis.analytics.kotlin.android.Analytics
import kotlinx.serialization.json.buildJsonObject

val client = Analytics("YOUR_WRITE_KEY", applicationContext) {
  endpoint = "YOUR_ENDPOINT"
  trackApplicationLifecycleEvents = true
  flushAt = 3
  flushInterval = 10
  // ...other config options
}

client.track(
  "Workout completed", 
  buildJsonObject { 
    put("workout_type", "Cardio");
    put("duration_minutes", 45);
