Android SDK チャットボットビルダー

Android dominates the global mobile market with over 3 billion active devices worldwide. For businesses building native Android apps with Kotlin or Java, in-app customer engagement is not a luxury — it is a retention necessity. Users who encounter friction when seeking help or guidance will uninstall and switch to a competitor, often within the first three days.

The Conferbot Android SDK brings a fully native chatbot experience to your Android app. Built for modern Android development, the SDK supports both Jetpack Compose and traditional XML layouts, follows Material You (Material Design 3) guidelines, leverages Kotlin coroutines for asynchronous operations, and integrates seamlessly with Firebase Cloud Messaging for push notifications.

Unlike WebView-based chat solutions that feel foreign and perform poorly, the Conferbot Android SDK renders native Android views that match your app's look, feel, and performance standards. Users interact with the chatbot as naturally as any other screen in your app. The bot itself is powered by the same no-code builder and AI engine that drives all Conferbot channels — build once, deploy everywhere.

This guide covers installation, Compose and XML integration, key features, theming, and best practices for delivering a production-grade chatbot experience in your Android app in 2026.

The Conferbot Android SDK is distributed via Maven Central and integrates into your Gradle build like any standard Android library.

Step 1: Add the Repository

In your project-level build.gradle or settings.gradle, ensure Maven Central is included:

repositories { mavenCentral() }

Step 2: Add the Dependency

In your app-level build.gradle:

implementation 'com.conferbot:sdk:1.0.0'

For Jetpack Compose support, also add:

implementation 'com.conferbot:sdk-compose:1.0.0'

Step 3: Sync and Initialize

Sync Gradle files, then initialize the SDK in your Application class:

Conferbot.initialize(context, "YOUR_BOT_ID")

Step 4: Add the Chat UI

Jetpack Compose:

ConferbotChatScreen(modifier = Modifier.fillMaxSize())

Or use the floating action button composable:

ConferbotFloatingButton()

XML Layouts:

Launch the chat as an Activity:

ConferbotChatActivity.launch(context)

Or embed as a Fragment:

ConferbotChatFragment.newInstance()

Step 5: Configure Push Notifications (Optional)

The SDK integrates with Firebase Cloud Messaging (FCM):

1. Set up FCM in your Firebase project
2. Pass the FCM token to the SDK: Conferbot.setDeviceToken(token)
3. The SDK handles incoming notification payloads and displays notifications automatically

Basic integration takes 15 minutes. The SDK supports API 21+ (Android 5.0 Lollipop and above), covering 99%+ of active Android devices.

The Conferbot Android SDK is built by Android developers, for Android developers. It follows modern Android architecture patterns and leverages the latest platform capabilities.

Jetpack Compose Support

First-class Jetpack Compose composables for the entire chat UI. Use ConferbotChatScreen, ConferbotFloatingButton, and ConferbotMessageList directly in your Compose layouts. The composables follow Compose best practices: stateless where possible, recomposition-efficient, and compatible with Navigation Compose.

Traditional XML Support

For apps not yet migrated to Compose, the SDK provides Activity and Fragment implementations. ConferbotChatActivity launches a full-screen chat, while ConferbotChatFragment embeds into your existing Fragment-based navigation. Both support the same feature set as the Compose version.

Material You (Material Design 3)

The SDK renders Material Design 3 components that respond to your app's dynamic color scheme on Android 12+. On older devices, the SDK falls back to your configured color scheme. Chat bubbles, buttons, input fields, and headers all follow Material 3 specs for shape, typography, and color.

Kotlin Coroutines

All asynchronous operations use Kotlin coroutines with structured concurrency. Message sending, receiving, and network operations run on appropriate dispatchers without blocking the UI thread. The SDK exposes Flow-based APIs for observing chat state, message streams, and connection status.

FCM Push Notifications

When the bot sends a message while the app is backgrounded, users receive a push notification via Firebase Cloud Messaging. Tap the notification to open the chat directly. The SDK handles notification payload parsing and deep linking automatically.

Offline Message Queuing

Messages typed while offline are stored in a local queue and sent automatically when connectivity returns. The SDK uses Android's ConnectivityManager to detect network state changes, ensuring no messages are lost during transient network disruptions.

ProGuard and R8 Compatible

The SDK ships with its own ProGuard rules. No additional configuration needed for release builds with code shrinking enabled. Tested with both ProGuard and R8 optimizers.

The SDK integrates with Android's theming system for seamless visual consistency with your app.

Theme Configuration

Configure the chat appearance through ConferbotTheme:

• primaryColor — Accent color for send button, links, and interactive elements
• surfaceColor — Background color for the chat screen
• userBubbleColor / botBubbleColor — Separate colors for user and bot message bubbles
• typography — Custom TypeStyle or font family for all text elements
• shapes — Corner radius for bubbles, cards, and buttons following Material 3 shape scale
• botAvatar — Custom drawable or URL for the bot avatar

Dynamic Color (Android 12+)

On Android 12 and above, the SDK can extract colors from the user's wallpaper using Material You dynamic color. Enable this with a single flag: useDynamicColor = true. Your chatbot adapts to each user's personal color theme.

Dark Theme Support

The SDK automatically respects the system dark theme or your app's AppCompatDelegate.setDefaultNightMode setting. Provide separate light and dark color configurations, or let Material You handle the adaptation automatically.

Event Listeners

Register listeners for chatbot events:

• OnMessageReceivedListener — Bot message arrives
• OnConversationEndedListener — A conversation flow completes
• OnHandoffListener — Conversation transfers to a live agent
• OnDataCapturedListener — User provides data through the bot flow
• OnErrorListener — SDK encounters an error

For Compose users, these events are also available as LaunchedEffect-compatible flows.

Custom Views

Replace default UI elements with your own implementations. The SDK provides interfaces for custom message bubble views, input bar views, header views, and quick reply layouts — both in Compose (composable slots) and XML (ViewFactory pattern).

Android's massive global install base means your app serves diverse users with diverse needs. Here are the chatbot use cases that deliver the highest impact.

Customer Support at Scale

Android apps in markets like India, Brazil, and Southeast Asia serve tens of millions of users. In-app chatbot support handles the volume that human agents cannot — resolving common inquiries instantly and routing complex issues to live agents. Apps with in-app support see 30% fewer negative Play Store reviews related to support responsiveness.

Guided Onboarding

Walk new users through your app's features conversationally. Instead of overwhelming users with all features at once, the chatbot asks what they want to achieve and guides them to the relevant screen with step-by-step instructions. This is especially effective for complex apps like fintech, health, and productivity tools.

Order and Delivery Tracking

E-commerce and food delivery apps can let users check order status, modify orders, report issues, and request refunds through conversational chat. The chatbot pulls order data in real time and presents it clearly, reducing the need for users to navigate through multiple screens.

Subscription and Payment Support

Handle billing inquiries, explain subscription tiers, process upgrade requests, and troubleshoot payment failures. For apps with in-app purchases or subscriptions, chatbot-driven support reduces involuntary churn from unresolved billing issues by 15-25%.

Feedback and Bug Reporting

Replace clunky bug report forms with conversational feedback collection. The chatbot asks what happened, when it happened, and what the user expected — collecting structured reports that developers can act on. Users find this 3x less frustrating than traditional forms.

Adding a chatbot to your Android app with the Conferbot SDK is straightforward for any Android developer familiar with Gradle dependencies and modern Android architecture.
