Android In-App Messages

Supported on: Android SDK 1.0.33+

You can A/B test this in-app message with no extra code — create an experiment on it in the Console and the SDK serves the assigned variant automatically. See Servable Surface Experiments.

In-app messages are configured in the AppDNA Console and displayed automatically by the SDK when trigger conditions are met. No code is required to show messages — the SDK evaluates triggers on every tracked event and presents the message if conditions match.

How It Works

You create an in-app message in the Console with content, layout, and trigger rules.
The message definition is synced to the SDK via the config bundle.
On every track() call (including auto-tracked events), the SDK evaluates all active message triggers.
If conditions match, the message is presented automatically.

In-app messages are fully server-driven. You can change the message content, trigger rules, and audience without an app update.

Message Types

Type	Description
`banner`	Small bar at the top or bottom of the screen
`modal`	Centered overlay with a dimmed background
`fullscreen`	Full-screen takeover
`tooltip`	Small popup anchored to a UI element

Triggers

Messages trigger based on events and optional conditions, configured in the Console:

Event match — e.g., trigger on workout_completed
Property conditions — e.g., duration >= 30
Frequency — once, once_per_session, or every_time
Delay — wait N seconds after the trigger event before showing

Module Access

val messages = AppDNA.inAppMessages

Module Methods

Method	Signature	Description
`suppressDisplay`	`suppressDisplay(suppress: Boolean)`	Suppress or resume in-app messages
`setDelegate`	`setDelegate(delegate: AppDNAInAppMessageDelegate?)`	Set a delegate for message callbacks

Suppressing Messages

Suppress messages during critical flows like checkout or onboarding to avoid interrupting the user:

// Suppress during purchase flow
AppDNA.inAppMessages.suppressDisplay(true)
startPurchaseFlow()

// Resume after purchase completes
fun purchaseDidComplete() {
    AppDNA.inAppMessages.suppressDisplay(false)
}

AppDNAInAppMessageDelegate

All 4 methods on this delegate fire from MessageManager for every in-app message lifecycle event. Register your delegate via AppDNA.inAppMessages.setDelegate(...). shouldShowMessage is a true veto. The SDK calls it BEFORE constructing the view or tracking the in_app_message_shown analytics event. If you return false, the message is suppressed entirely — no view, no analytics. The interface’s default implementation returns true, so hosts that don’t implement this method continue to see all messages. Implement the delegate to respond to message lifecycle events:

interface AppDNAInAppMessageDelegate {
    fun onMessageShown(messageId: String, trigger: String)
    fun onMessageAction(messageId: String, action: String, data: Map<String, Any>?)
    fun onMessageDismissed(messageId: String)
    fun shouldShowMessage(messageId: String): Boolean = true
}

Example Implementation

import ai.appdna.sdk.AppDNA
import ai.appdna.sdk.AppDNAInAppMessageDelegate

class MessageHandler : AppDNAInAppMessageDelegate {

    override fun onMessageShown(messageId: String, trigger: String) {
        Log.d("Message", "Message shown: $messageId (trigger: $trigger)")
    }

    override fun onMessageAction(messageId: String, action: String, data: Map<String, Any>?) {
        val url = data?.get("url") as? String
        if (url != null) {
            // Handle deep link or URL action
            navigate(url)
        }
    }

    override fun onMessageDismissed(messageId: String) {
        Log.d("Message", "Message dismissed: $messageId")
    }

    override fun shouldShowMessage(messageId: String): Boolean {
        // Return false to prevent the message from being shown
        return true
    }

    private fun navigate(url: String) { /* ... */ }
}

AppDNA.inAppMessages.setDelegate(MessageHandler())

Rich Media

In-app messages support rich media content configured in the Console:

Lottie animations — animated hero images or backgrounds
Video — inline video with optional autoplay and looping
Icon buttons — CTA buttons with icon references (Lucide, Material, or emoji)
Haptic feedback — triggered on message display or button taps
Particle effects — confetti, sparkles, or other effects on message actions
Blur backdrop — glassmorphism-style blurred background for modals

See the Rich Media guide for details on supported formats and configuration.

Auto-Tracked Events

Event	Trigger
`in_app_message_shown`	An in-app message is displayed
`in_app_message_clicked`	User taps an action in the message
`in_app_message_dismissed`	Message is closed
`in_app_message_received`	(Pending-message channel) A message is received before display gating

Full Example

import ai.appdna.sdk.AppDNA
import ai.appdna.sdk.AppDNAInAppMessageDelegate

class AppCoordinator : AppDNAInAppMessageDelegate {

    fun setup() {
        AppDNA.inAppMessages.setDelegate(this)
    }

    fun startOnboarding() {
        // Suppress messages during onboarding
        AppDNA.inAppMessages.suppressDisplay(true)
        presentOnboardingFlow()
    }

    fun onboardingDidFinish() {
        // Resume messages after onboarding
        AppDNA.inAppMessages.suppressDisplay(false)
    }

    // MARK: AppDNAInAppMessageDelegate

    override fun onMessageShown(messageId: String, trigger: String) {
        // Optionally track in your own analytics
    }

    override fun onMessageAction(messageId: String, action: String, data: Map<String, Any>?) {
        when (action) {
            "deep_link" -> (data?.get("url") as? String)?.let { navigate(it) }
            "dismiss" -> { }
            else -> { }
        }
    }

    override fun onMessageDismissed(messageId: String) {
        // Message closed
    }

    override fun shouldShowMessage(messageId: String): Boolean = true

    private fun navigate(url: String) { /* ... */ }
    private fun presentOnboardingFlow() { /* ... */ }
}

In-app messages are created in the Console under Engagement > In-App Messages. Design the message, set trigger rules, and publish. The SDK handles everything else.
