Version 4

Migration guide

Sendbird Chat SDK v4 for Android has introduced major breaking changes to streamline the code structure and enhance its scalability.

This page explains the breaking changes and provides a step-by-step guide for migrating to v4.

Requirements

The minimum requirements for v4 are the following.

Android 5.0 (API level 21) or higher
Java 8 or higher
Android Gradle plugin 3.4.2 or higher
Firebase Cloud Messaging 19.0.1 or higher

Breaking changes

The following breaking changes have been made to the Chat SDK v4 for Android. For a full list of name changes, see the changelog section.

Structural changes

Convert language from Java to Kotlin.
Rename the main class from SendBird to SendbirdChat.
Add onConnected and onDisconnected to ConnectionHandler.
Split ChannelHandler into BaseChannelHandler, GroupChannelHandler, and OpenChannelHandler.
The requestId parameter is added to the file onProgress interface. interface FileMessagesWithProgressHandler, fun onProgress(bytesSent: Int, totalBytesSent: Int, totalBytesToSend: Int) is changed to fun onProgress(requestId: String, bytesSent: Int, totalBytesSent: Int, totalBytesToSend: Int)
Creation of Sendbird instances is no longer available in v4.
Separate existing Params classes such as UserMessageParams into UserMessageCreateParams and UserMessageUpdateParams as shown below.

From v3	To v4
`GroupChannelParams`	`GroupChannelCreateParams` `GroupChannelUpdateParams`
`OpenChannelParams`	`OpenChannelCreateParams` `OpenChannelUpdateParams`
`UserMessageParams`	`UserMessageCreateParams` `UserMessageUpdateParams`
`FileMessageParams`	`FileMessageCreateParams` `FileMessageUpdateParams`

Renew the package structure for better management.
Replace builder classes with class constructors.
Change getter and setter functions to properties. For example, GroupChannelListQuery.hasNext() has changed to GroupChannelListQuery.hasNext, or GroupChannelListQuery.getHasNext() for Java.
Remove setter functions that return themselves. For example, GroupChannelCreateParams.setData(value): GroupChannelCreateParams has been removed and should now be set by accessing the corresponding property.
Change the static function OpenChannelCreateParams.clone to a non-static function OpenChannelCreateParams(instance).clone.
Specify nullability for return types and parameters.
Unify callback handlers.
Move nested classes to the top level. For example, com.sendbird.android.user.query.UserListQuery.UserListQueryResultHandler has changed to com.sendbird.android.handler.UserListQueryResultHandler.
Remove redundant suffixes such as withUserId in function names.
All enum.from(value:String?) functions have become internal functions.
List interface preferred to the MutableList interface.

Other changes

Remove ConnectionManager which was deprecated in v3.
Local caching in v4 can facilitate caching-related functionalities and more. SyncManager will soon be deprecated, so we highly recommend you use local caching instead.
Remove setters for Query classes and add corresponding Params classes.
Some methods and properties have been removed or replaced. For example, GroupChannelCreateParams.addUser and GroupChannelCreateParams.addUsers are replaced by GroupChannelCreateParams.users. You can see the full list of changes in the changelog section.

Migrating to v4

Migration from v3 to v4 can be done manually or, for Mac users, using a migration script.

Sendbird Chat SDK v4 will likely prevent your app from compiling until all migration tasks are complete and all errors are fixed. After fixing all the blocking errors, further work may be needed to remove warnings and align the updated SDK with your app. We recommend you allow a generous timeline for the task. Depending on the level of dependency, it may take a few hours to a week.

Migration Script

For Mac users, a migration script is available to provide a smoother migration experience. While not comprehensive of all changes made to v4, the script reduces a significant amount of work needed for the migration. You can check what changes the script supports or doesn't support in the changelog section.

To use the migration script, follow the instructions below.

Download the migration script to the top of the project directory.
Give execution permission for the script with chmod +x migration_script_v3_to_v4.sh.
Run the migration script at the top of your project.
After running the migration script, check the changes made to your project to prevent any unexpected errors.

Note: If you use the migration script, you can skip Step 1 through Step 3 and go directly to Step 4.

Step 1 Replace SDK import names

It's recommended to remove every import from Sendbird since classes have been repackaged in v4. Find and replace all instances of import com.sendbird.android.* with an empty string.

Step 2 Replace instances

Find and replace all instances of SendBird with SendbirdChat. To find the exact SendBird.*** calls as opposed to any word containing "Sendbird," we recommend that you use the regular expression of SendBird which is [S]end[B]ird\.. Also, find and replace all instances of SendBirdException with SendbirdException.

Step 3 Insert new imports

Remove the SDK v3 from your project and insert the following imports to every class in which the SendBird classes were used. Then, optimize your imports by using the import optimization feature provided by your IDE.

import com.sendbird.android.channel.*;
import com.sendbird.android.SendbirdChat;
import com.sendbird.android.message.*;
import com.sendbird.android.user.*;
import com.sendbird.android.handler.*;
import com.sendbird.android.channel.query.*;
import com.sendbird.android.message.query.*;
import com.sendbird.android.exception.*;

Step 4 Handle common errors

The following are manual fixes to errors that may arise when migrating to v4.

Initializing Sendbird

Note: You must initialize the SendbirdChat instance before calling any SDK interfaces.

In v3, the app was initialized using SendBird.init().

In v4, a new class called InitParams has been introduced. After creating an object from InitParams, you should pass the object to the SendbirdChat.init() function as follows.

From v3

KotlinJava

SendBird.init(APP_ID, applicationContext)

To v4

KotlinJava

val params = InitParams(APP_ID, applicationContext, false)
SendbirdChat.init(params, object : InitResultHandler {
    override fun onMigrationStarted() {}
    override fun onInitFailed(e: SendbirdException) {}
    override fun onInitSucceed() {}
})

Connecting to or disconnecting from Sendbird

In v3, ConnectHandler and DisconnectHandler were inner classes of the SendBird class.

In v4, ConnectHandler and DisconnectHandler are public classes, so you can access the classes without adding Sendbird.

Connecting to Sendbird

From v3

KotlinJava

SendBird.connect(USER_ID) { user, e ->
    // ...
}

To v4

KotlinJava

SendbirdChat.connect(USER_ID) { user, e ->
    // ...
}

Disconnecting from Sendbird

From v3

KotlinJava

SendBird.disconnect {
    // ...
}

To v4

KotlinJava

SendbirdChat.disconnect {
    // ...
}

Creating open channels and group channels

In v3, there were several functions for creating channels depending on the input parameters for both group channels and open channels. The callback handlers were also inner classes of GroupChannel and OpenChannel as shown below.

For v4, we removed all channel creation functions except GroupChannel.createChannel() for group channels and OpenChannel.createChannel() for open channels. Now you can pass all parameters via GroupChannelCreateParams and OpenChannelCreateParams. Also, CallbackHandlers has been split into GroupChannelCallbackHandler and OpenChannelCallbackHandler.

Open channels

From v3

KotlinJava

OpenChannel.createChannelWithOperatorUserIds(NAME, null, null, null) { openChannel, e ->
    // ...
}

To v4

KotlinJava

val params = OpenChannelCreateParams().apply {
    name = NAME
}
OpenChannel.createChannel(params) { openChannel, e ->
    // ...
}

Group channels

From v3

KotlinJava

GroupChannel.createChannelWithUserIds(USER_IDS, DISTINCT) { groupChannel, e ->
    // ...
}

To v4

KotlinJava

val params = GroupChannelCreateParams().apply {
    userIds = USER_IDS
    isDistinct = DISTINCT
}
GroupChannel.createChannel(params) { groupChannel, e ->
    // ...
}

Subscribing to channel handler

In v3, the ChannelHandler class was an inner class of the SendBird class and worked for both group channels and open channels.

In v4, the ChannelHandler class is divided in two classes: GroupChannelHandler for group channels and OpenChannelHandler for open channels.

From v3

KotlinJava

SendBird.addChannelHandler(UNIQUE_HANDLER_ID, object : ChannelHandler() {
    // ...
})

To v4

KotlinJava

// Group channel event handlers
addChannelHandler(UNIQUE_HANDLER_ID, object : GroupChannelHandler() {
    // You can override functions here.
})

// Open channel event handlers
addChannelHandler(UNIQUE_HANDLER_ID, object : OpenChannelHandler() {
    // You can override functions here.
})

Retrieving channels

In v3, you could retrieve channel objects via the channel URL and by refreshing the channel object.

In v4, to retrieve group channels, use GroupChannelCallbackHandler instead of GroupChannel.GroupChannelGetHandler and CompletionHandler instead of GroupChannel.GroupChannelRefreshHandler.

From v3

KotlinJava

GroupChannel.getChannel(CHANNEL_URL) { groupChannel, e ->
    // ...
}

// ...

groupChannel.refresh {
    // ...
}

To v4

KotlinJava

GroupChannel.getChannel(CHANNEL_URL) { groupChannel, e ->
    // ...
}

// ...

groupChannel.refresh {
    // ...
}

To retrieve open channels, use OpenChannelCallbackHandler instead of OpenChannel.OpenChannelGetHandler.

From v3

KotlinJava

OpenChannel.getChannel(CHANNEL_URL) { openChannel, e ->
    // ...
}

To v4

KotlinJava

OpenChannel.getChannel(CHANNEL_URL) { openChannel, e ->
    // ...
}

Retrieving messages

In v3, you needed to pass all individual parameters into specific functions to retrieve messages from a group channel.

In v4, you need to pass MessageListParams to functions instead of all individual parameters. The callback handler has also changed, so you should use BaseMessagesHandler instead of BaseChannel.GetMessagesHandler.

From v3

KotlinJava

groupChannel.getPreviousMessagesByTimestamp(OLDEST_MESSAGE_CREATED_AT, false, LIMIT, true, BaseChannel.MessageTypeFilter.ALL, null) { list, e ->
    // ...
}

To v4

KotlinJava

val params = MessageListParams().apply {
    previousResultSize = LIMIT
    reverse = false
    messageTypeFilter = MessageTypeFilter.ALL
}
groupChannel.getMessagesByTimestamp(OLDEST_MESSAGE_CREATED_AT, params) { list, e ->
    // ...
}

Sending messages

In v3, there were several ways to send messages. BaseChannel.SendUserMessageHandler was used for sending UserMessage and BaseChannel.UpdateUserMessageHandler was used for updating UserMessage.

In v4, the two callback handlers have been merged into UserMessageHandler which can be used for both sending and updating UserMessage.

From v3

KotlinJava

// Send text message
val tempUserMessage: UserMessage = groupChannel.sendUserMessage(TEXT) { userMessage, e ->
    // ...
}

// Send text message with UserMessageParams.
val params = UserMessageParams().apply {
    setMessage(TEXT)
    setCustomType(CUSTOM_TYPE)
}
val tempUserMessage = groupChannel.sendUserMessage(params) { userMessage, e ->
    // ...
}

// Update UserMessage
groupChannel.updateUserMessage(message.getMessageId(), EDITED_TEXT, null, null) { userMessage, e ->
    // ...
}

To v4

KotlinJava

// Send text message
val tempUserMessage: UserMessage = groupChannel.sendUserMessage(TEXT) { userMessage, e ->
    // ...
}

// Send text message with UserMessageCreateParams.
val params = UserMessageCreateParams().apply {
    message = TEXT
    customType = CUSTOM_TYPE
}
val tempUserMessage = groupChannel.sendUserMessage(params) { userMessage, e ->
    // ...
}

// Update UserMessage
val params = UserMessageUpdateParams().apply {
    message = EDITED_TEXT
}
groupChannel.updateUserMessage(message.getMessageId(), params) { userMessage, e ->
    // ...
}

As for FileMessage, the callback handlers BaseChannel.SendFileMessageHandler and BaseChannel.UpdateFileMessageHandler have been merged to FileMessageHandler which can be used for sending and updating FileMessages.

From v3

KotlinJava

val params = FileMessageParams().apply {
    setFile(FILE)
    setFileName(NAME)
    setMimeType(MIME)
    setFileSize(SIZE)
    setThumbnailSizes(THUMBNAIL_SIZES)
}

// Send image with specified thumbnail dimensions.
val tempFileMessage: FileMessage? = groupChannel.sendFileMessage(params) { message, e ->
    // ...
}

To v4

KotlinJava

val params = FileMessageCreateParams().apply {
    file = FILE
    fileName = NAME
    mimeType = MIME
    fileSize = SIZE
    thumbnailSizes = THUMBNAIL_SIZES
}

// Send image with specified thumbnail dimensions.
val tempFileMessage: FileMessage? = groupChannel.sendFileMessage(params) { fileMessage, e ->
    // ...
}

To delete a message, use CompletionHandler instead of BaseChannel.DeleteMessageHandler.

To v4

KotlinJava

groupChannel.deleteMessage(MESSAGE) {
    // ...
}

Note: These changes to sending, updating, or deleting UserMessages and FileMessages apply in the same way to open channels.

Entering and exiting open channels

In v4, you should use CompletionHandler instead of OpenChannel.OpenChannelEnterHandler() to enter an open channel and OpenChannelExitHandler to exit an open channel.

To v4

KotlinJava

// Enter an open channel.
openChannel.enter {
    // ...
}

// Exit an open channel.
openChannel.exit {
    // ...
}

Functions in need of handlers

Push preferences

In v3, a true or false value was used to set push preferences for a channel.

In v4, the PushTriggerOption should be set to one of the following four values: ALL, OFF, MENTION_ONLY, and DEFAULT.

From v3

KotlinJava

groupChannel.setPushPreference(on) {
    // ...
}
val pushCurrentlyEnabled: Boolean = groupChannel.isPushEnabled

To v4

KotlinJava

groupChannel.setMyPushTriggerOption(GroupChannel.PushTriggerOption.MENTION_ONLY) {
    // ...
}
val options: GroupChannel.PushTriggerOption = groupChannel.myPushTriggerOption

Mark as read and mark as delivered

You should pass CompletionHandler to groupChannel.markAsRead() and pass the data that you receive from Firebase Cloud Messaging (FCM) push notifications to SendbirdChat.markAsDelivered().

To v4

KotlinJava

groupChannel.markAsRead {
    // ...
}
SendbirdChat.markAsDelivered(remoteMessage.getData())

Unread member count and undelivered member count

channel.getReadReceipt() and channel.getDeliveryReceipt() functions have been renamed as the following in v4.

To v4

KotlinJava

groupChannel.getUnreadMemberCount(MESSAGE)
groupChannel.getUndeliveredMemberCount(MESSAGE)
