Upgrading from V5 to V6

Migrate your Android app from CometChat UI Kit V5 to V6 with updated dependencies, architecture, and API changes.

Introduction

The CometChat V5 Android UI Kit was a single Java module (com.cometchat:chat-uikit-android) that shipped all UI components, ViewModels, and resources in one artifact under the com.cometchat.chatuikit package.

V6 splits the UI Kit into three modules built entirely in Kotlin:

Module	Artifact	Description
Core	com.cometchat:chatuikit-core	Shared ViewModels, Repositories, DataSources, and events — used by both UI modules.
Kotlin (XML Views)	com.cometchat:chat-uikit-kotlin	Traditional XML-based Views for Activities and Fragments.
Jetpack Compose	com.cometchat:chat-uikit-compose	Declarative Compose components.

Choose the UI module that fits your project — both depend on chatuikit-core automatically.

Key Migration Changes

The following table summarizes the most impactful changes when migrating from V5 to V6:

Area	V5	V6
Language	Java	Kotlin
Modules	Single com.cometchat:chat-uikit-android	com.cometchat:chat-uikit-kotlin (XML) or com.cometchat:chat-uikit-compose (Compose) + shared chatuikit-core
Import path	com.cometchat.chatuikit.*	com.cometchat.uikit.kotlin.presentation.* or com.cometchat.uikit.compose.presentation.*
CometChatUIKit import	com.cometchat.chatuikit.shared.cometchatuikit.CometChatUIKit	com.cometchat.uikit.core.CometChatUIKit
UIKitSettings import	com.cometchat.chatuikit.shared.cometchatuikit.UIKitSettings	com.cometchat.uikit.core.UIKitSettings
State management	LiveData	StateFlow / Kotlin coroutines
Architecture	View + ViewModel + Adapter (2-layer)	View → ViewModel → Repository → DataSource (4-layer Clean Architecture)
Conversation list	CometChatConversations	CometChatConversations
Thread header	CometChatThreadedMessagesHeader	CometChatThreadHeader
Events	CometChat*Events.addListener() / removeListener()	CometChatEvents singleton with SharedFlow — collect in a coroutine scope
Theming	Palette + Typography objects	XML theme attributes extending CometChatTheme.DayNight (Kotlin XML) or CometChatTheme {} composable (Compose)
Styling	setStyle(ComponentStyle) methods with style objects	XML @StyleRes theme attributes (Kotlin XML) or style data classes with .default().copy() (Compose)
View slots	ConversationsViewHolderListener with createView/bindView (Java)	Same pattern in Kotlin XML or @Composable lambdas in Compose
ViewModel access	getViewModel() returns Java ViewModel with LiveData	getViewModel() / setViewModel() with Kotlin ViewModel using StateFlow
List operations	Direct list manipulation via adapter	ListOperations<T> interface with addItem, removeItem, updateItem, moveItemToTop, batch {}
Repository	Not exposed	Swappable via Factory pattern — implement interface, inject via *ViewModelFactory
Min SDK	24	28

Dependency Changes

V5 (before)

build.gradle

dependencies {
    implementation 'com.cometchat:chat-uikit-android:5.x.x'
}

V6 — Kotlin XML Views (after)

build.gradle

dependencies {
    implementation 'com.cometchat:chat-uikit-kotlin:6.x.x'
    // chatuikit-core is pulled in transitively
}

V6 — Jetpack Compose (after)

build.gradle

dependencies {
    implementation 'com.cometchat:chat-uikit-compose:6.x.x'
    // chatuikit-core is pulled in transitively
}

V6 raises the minimum SDK from 24 to 28. Update minSdk in your build.gradle accordingly.

Component Renames

Most components keep the same class name but move to a new package. The following were also renamed:

V5 Name	V6 Name
CometChatConversations	CometChatConversations
CometChatThreadedMessagesHeader	CometChatThreadHeader

All other components (CometChatUsers, CometChatGroups, CometChatMessageHeader, CometChatMessageList, CometChatMessageComposer, CometChatIncomingCall, CometChatOutgoingCall, CometChatCallButtons, CometChatCallLogs, CometChatGroupMembers) retain their names but live under the new V6 package paths.

Import Path Changes

CometChatUIKit & UIKitSettings

V5 (Java)

import com.cometchat.chatuikit.shared.cometchatuikit.CometChatUIKit;
import com.cometchat.chatuikit.shared.cometchatuikit.UIKitSettings;

V6 (Kotlin)

import com.cometchat.uikit.core.CometChatUIKit
import com.cometchat.uikit.core.UIKitSettings

UI Components

V5 (Java)

import com.cometchat.chatuikit.conversations.CometChatConversations;
import com.cometchat.chatuikit.users.CometChatUsers;
import com.cometchat.chatuikit.groups.CometChatGroups;
import com.cometchat.chatuikit.messageheader.CometChatMessageHeader;
import com.cometchat.chatuikit.messagelist.CometChatMessageList;
import com.cometchat.chatuikit.messagecomposer.CometChatMessageComposer;

V6 — Kotlin XML

import com.cometchat.uikit.kotlin.presentation.conversations.ui.CometChatConversations
import com.cometchat.uikit.kotlin.presentation.users.ui.CometChatUsers
import com.cometchat.uikit.kotlin.presentation.groups.ui.CometChatGroups
import com.cometchat.uikit.kotlin.presentation.messageheader.ui.CometChatMessageHeader
import com.cometchat.uikit.kotlin.presentation.messagelist.ui.CometChatMessageList
import com.cometchat.uikit.kotlin.presentation.messagecomposer.ui.CometChatMessageComposer

V6 — Jetpack Compose

import com.cometchat.uikit.compose.presentation.conversations.ui.CometChatConversations
import com.cometchat.uikit.compose.presentation.users.ui.CometChatUsers
import com.cometchat.uikit.compose.presentation.groups.ui.CometChatGroups
import com.cometchat.uikit.compose.presentation.messageheader.ui.CometChatMessageHeader
import com.cometchat.uikit.compose.presentation.messagelist.ui.CometChatMessageList
import com.cometchat.uikit.compose.presentation.messagecomposer.ui.CometChatMessageComposer

Events Migration

In V5, events used the addListener / removeListener pattern with unique string IDs:

V5 (Java)

CometChatMessageEvents.addListener("unique-id", new CometChatMessageEvents() {
    @Override
    public void onMessageSent(BaseMessage message) {
        // Handle message sent
    }
});
// Cleanup
CometChatMessageEvents.removeListener("unique-id");

In V6, events use the CometChatEvents singleton with Kotlin SharedFlow. Collect in a coroutine scope:

V6 (Kotlin)

lifecycleScope.launch {
    CometChatEvents.messageEvents.collect { event ->
        when (event) {
            is MessageEvent.Sent -> { /* Handle message sent */ }
            is MessageEvent.Edited -> { /* Handle message edited */ }
            is MessageEvent.Deleted -> { /* Handle message deleted */ }
        }
    }
}
// No manual cleanup needed — lifecycleScope auto-cancels

State Management Migration

V5 — LiveData observers (Java)

V5

conversationsViewModel.getConversationList().observe(this, new Observer<List<Conversation>>() {
    @Override
    public void onChanged(List<Conversation> conversations) {
        // Update UI with conversations
    }
});

V6 — StateFlow collectors (Kotlin)

V6

lifecycleScope.launch {
    conversationsViewModel.uiState.collect { state ->
        when (state) {
            is UIState.Loading -> { /* Show loading */ }
            is UIState.Success -> { /* Update UI with state.data */ }
            is UIState.Error -> { /* Show error */ }
        }
    }
}

Styling Migration

V5 — Style objects (Java)

V5

ConversationsStyle style = new ConversationsStyle();
style.setBackground(Color.WHITE);
style.setTitleColor(Color.BLACK);
style.setBorderWidth(1);
style.setBorderColor(Color.GRAY);
cometChatConversations.setStyle(style);

V6 — Kotlin XML: Theme attributes in themes.xml

V6 — themes.xml

<resources>
    <style name="AppTheme" parent="CometChatTheme.DayNight">
        <item name="cometchatPrimaryColor">#F76808</item>
        <item name="cometchatBackgroundColor">#FFFFFF</item>
        <item name="cometchatTextPrimaryColor">#141414</item>
        <item name="android:fontFamily">@font/your_custom_font</item>
    </style>

    <!-- Override a specific component style -->
    <style name="CustomConversationsStyle" parent="CometChatConversations">
        <item name="cometchatSeparatorColor">#E0E0E0</item>
        <item name="cometchatItemBackgroundColor">#FAFAFA</item>
    </style>
</resources>

V6 — Jetpack Compose: Style data classes

V6 — Compose

CometChatConversations(
    style = CometChatConversationsStyle.default().copy(
        backgroundColor = Color.White,
        titleColor = Color.Black,
        separatorColor = Color.LightGray
    )
)

Component-by-Component Migration

Conversations

V5 — CometChatConversations (Java)

CometChatConversations conversations = findViewById(R.id.conversations);
conversations.setOnItemClick(new OnItemClick<Conversation>() {
    @Override
    public void onItemClick(Conversation conversation, int position) {
        // Handle click
    }
});

V6 — CometChatConversations (Kotlin)

val conversations = findViewById<CometChatConversations>(R.id.conversations)
conversations.setOnItemClick { conversation ->
    // Handle click
}

Users

V5 — CometChatUsers (Java)

CometChatUsers users = findViewById(R.id.users);
users.setOnItemClick(new OnItemClick<User>() {
    @Override
    public void onItemClick(User user, int position) {
        // Handle click
    }
});

V6 — CometChatUsers (Kotlin)

val users = findViewById<CometChatUsers>(R.id.users)
users.setOnItemClick { user ->
    // Handle click
}

Groups

V5 — CometChatGroups (Java)

CometChatGroups groups = findViewById(R.id.groups);
groups.setOnItemClick(new OnItemClick<Group>() {
    @Override
    public void onItemClick(Group group, int position) {
        // Handle click
    }
});

V6 — CometChatGroups (Kotlin)

val groups = findViewById<CometChatGroups>(R.id.groups)
groups.setOnItemClick { group ->
    // Handle click
}

Message Header

V5 — CometChatMessageHeader (Java)

CometChatMessageHeader header = findViewById(R.id.messageHeader);
header.setOnBackButtonPressed(new OnBackPress() {
    @Override
    public void onBack() {
        // Handle back
    }
});

V6 — CometChatMessageHeader (Kotlin)

val header = findViewById<CometChatMessageHeader>(R.id.messageHeader)
header.setOnBackPress {
    // Handle back
}

Message List

V5 — CometChatMessageList (Java)

CometChatMessageList messageList = findViewById(R.id.messageList);
messageList.setOnThreadRepliesClick(new OnThreadRepliesClick() {
    @Override
    public void onThreadRepliesClick(Context context, BaseMessage message, CometChatMessageTemplate template) {
        // Handle thread click
    }
});

V6 — CometChatMessageList (Kotlin)

val messageList = findViewById<CometChatMessageList>(R.id.messageList)
messageList.setOnThreadRepliesClick { context, message, template ->
    // Handle thread click
}

Message Composer

V5 — CometChatMessageComposer (Java)

CometChatMessageComposer composer = findViewById(R.id.messageComposer);
composer.setOnSendButtonClick(new OnSendButtonClick() {
    @Override
    public void onSendButtonClick(Context context, BaseMessage message) {
        // Handle send
    }
});

V6 — CometChatMessageComposer (Kotlin)

val composer = findViewById<CometChatMessageComposer>(R.id.messageComposer)
composer.setOnSendButtonClick { context, message ->
    // Handle send
}

Call Components

Call components (CometChatIncomingCall, CometChatOutgoingCall, CometChatCallButtons, CometChatCallLogs) keep the same class names in V6. Update the import paths:

V5 (Java)

import com.cometchat.chatuikit.calls.incoming.CometChatIncomingCall;
import com.cometchat.chatuikit.calls.outgoing.CometChatOutgoingCall;
import com.cometchat.chatuikit.calls.callbuttons.CometChatCallButtons;
import com.cometchat.chatuikit.calls.calllogs.CometChatCallLogs;

V6 — Kotlin XML

import com.cometchat.uikit.kotlin.presentation.incomingcall.CometChatIncomingCall
import com.cometchat.uikit.kotlin.presentation.outgoingcall.CometChatOutgoingCall
import com.cometchat.uikit.kotlin.presentation.callbuttons.CometChatCallButtons
import com.cometchat.uikit.kotlin.presentation.calllogs.ui.CometChatCallLogs

Architecture Changes

V6 introduces a 4-layer Clean Architecture that replaces V5’s 2-layer View + ViewModel pattern:

View → ViewModel → Repository → DataSource

ViewModel Access

V5 (Java)

// V5 — Java ViewModel with LiveData
ConversationsViewModel viewModel = cometChatConversations.getViewModel();
viewModel.getConversationList().observe(this, conversations -> {
    // React to data
});

V6 (Kotlin)

// V6 — Kotlin ViewModel with StateFlow
val viewModel = conversations.getViewModel()
lifecycleScope.launch {
    viewModel.uiState.collect { state ->
        // React to data
    }
}

// You can also inject a custom ViewModel
conversations.setViewModel(myCustomViewModel)

List Operations

V5 required direct adapter manipulation. V6 provides a ListOperations<T> interface:

V6 — ListOperations

val viewModel = conversations.getViewModel()

// Single operations
viewModel.addItem(conversation)
viewModel.removeItem(conversation)
viewModel.updateItem(conversation)
viewModel.moveItemToTop(conversation)

// Batch operations
viewModel.batch {
    addItem(conversation1)
    updateItem(conversation2)
    removeItem(conversation3)
}

Custom Repository

V6 exposes the repository layer, allowing you to swap data sources:

V6 — Custom Repository

// Implement the repository interface
class MyConversationRepository : ConversationsRepository {
    override suspend fun fetchConversations(): List<Conversation> {
        // Your custom data source
    }
}

// Inject via ViewModelFactory
val factory = CometChatConversationsViewModelFactory(
    repository = MyConversationRepository()
)
conversations.setViewModelFactory(factory)
