ZIM upgrade Guide


This article provides some instructions and considerations for upgrading the ZIM SDK for Android version.

2.19.0 upgrade guide

Warning

Starting from version 2.19.0, the following interfaces have undergone significant changes. Therefore, when upgrading from an older version to version 2.19.0, please read the following guidelines.

The original downloadMediaFile API is deprecated. Please use the new downloadMediaFile instead. The updated downloadMediaFile introduces a new config parameter, which can be used to specify the download of individual media content in multi-item messages.

The ZIMMediaDownloadedCallback callback has been updated to support multi-item messages. Developers need to fix the calls according to the IDE's compile error hints:

Usage in Version 2.19.0(For Multi-item Messages)
Usage in Version 2.19.0(For other Messages)
Old Usage
// Assume multipleMessage.messageInfoList[0] is a text message, and multipleMessage.messageInfoList[1] is an image message
ZIMMultipleMessage multipleMessage = (ZIMMultipleMessage) message;
ZIMMediaDownloadConfig config = new ZIMMediaDownloadConfig();
// Specify to download the image message
config.messageInfoIndex = 1;

zim.getInstance().downloadMediaFile(multipleMessage, ZIMMediaFileType.ORIGINAL_FILE, config, new ZIMMediaDownloadedCallback() {
    @Override
    public void onMediaDownloadingProgress(ZIMMessage message, long currentFileSize, long totalFileSize) {
        // Download progress
        // Developers need to check the type of the message and cast it to the corresponding message type
        if (message instanceof ZIMMultipleMessage) {
            ZIMMultipleMessage multipleMessage = (ZIMMultipleMessage) message;
            // Handle multi-item messages
        }
        // Handle other types of messages
        ......
    }

    @Override
    public void onMediaDownloaded(ZIMMessage message, ZIMError errorInfo) {
        // Download complete
        // Developers need to check the type of the message and cast it to the corresponding message type
        if (message instanceof ZIMMultipleMessage) {
            ZIMMultipleMessage multipleMessage = (ZIMMultipleMessage) message;
            // Handle multi-item messages
        }
        // Handle other types of messages
        ......
    }
});

sendMessage

The sendMediaMessage and the old sendMessage methods are deprecated. A new sendMessage method is introduced, which supports sending any type of message.

The callback for sendMessage is different from the callback of the old method with the same name. It has changed from ZIMMediaMessageSentCallback to ZIMMessageSentFullCallback.

In ZIMMessageSentFullCallback, the message parameter in onMediaUploadingProgress has changed from ZIMMessage to ZIMMediaMessage to ensure that only media messages are notified in the callback. Developers need to fix the calls according to the compile error hints from the IDE. (Currently, only developers using the replyMessage interface will be affected by the need to resolve compile errors.)

Usage in Version 2.19.0
Old Usage
ZIMImageMessage imageMessage = (ZIMImageMessage) message;

zim.getInstance().sendMessage(imageMessage, "TO_CONVERSATION_ID", ZIMConversationType.PEER, new ZIMMessageSentFullCallback() {
    @Override
    public void onMessageSent(ZIMMessage message, ZIMError errorInfo) {
        // Message send result
    }

    @Override
    public void onMediaUploadingProgress(ZIMMediaMessage message, long currentFileSize, long totalFileSize) {
        // Multimedia upload progress
    }

    @Override
    public void onMessageAttached(ZIMMessage message) {
        // Developers can listen to this callback to execute business logic before sending the message
    }
});

2.18.0 upgrade guide

Warning

Starting from version 2.18.0, the following interfaces have undergone significant changes. Therefore, when upgrading from an older version to version 2.18.0, please read the following guidelines.

Callback on receiving one-to-one messages

The deprecated callback onReceivePeerMessage for receiving one-to-one messages has been replaced by onPeerMessageReceived.

The new callback supports the following features:

  • When a user is online, they can receive one-to-one messages through this callback.
  • When a user logs back into the ZIM SDK, they can receive all one-to-one messages received during their offline period (up to 7 days).
Untitled
// New callback
public void onPeerMessageReceived(ZIM zim, ArrayList<ZIMMessage> messageList,
                                    ZIMMessageReceivedInfo info, String fromUserID) {}

// Old callback
public void onReceivePeerMessage(ZIM zim, ArrayList<ZIMMessage> messageList,
                                    String fromUserID) {}

Callback on receiving room messages

The deprecated callback onReceiveRoomMessage for receiving room messages has been replaced by onRoomMessageReceived.

The new callback supports the following features:

  • When a user is online, they can receive online room messages through this callback.
  • When a user goes from offline to online and is still in the room, they can receive all room messages that were sent during their offline period through this callback.
Untitled
// New callback
public void onRoomMessageReceived(ZIM zim, ArrayList<ZIMMessage> messageList,
                                    ZIMMessageReceivedInfo info, String fromRoomID) {}

// Old callback
public void onReceiveRoomMessage(ZIM zim, ArrayList<ZIMMessage> messageList,
                                    String fromRoomID) {}

Callback on receiving group messages

The deprecated callback onReceiveGroupMessage for receiving group messages has been replaced by onGroupMessageReceived.

The new callback supports the following features:

  • When the user is online, they can receive online group messages through this callback.
  • When the user logs back into the ZIM SDK, they can receive all group chat messages received during the offline period (up to 7 days) through this callback.

2.16.0 Upgrade Guide

Warning

Starting from version 2.16.0, there are significant changes to the following interfaces. Therefore, when upgrading from an older version to version 2.16.0, please read the following guide.

callCancel

Note

The following changes only apply to advanced mode call invitations.

In the new version of callCancel, if the parameter userIDs contains a userID, this interface will only cancel the invitation for that callee. If the userIDs parameter is empty, this interface will cancel the invitation for all callees.

For the old version of the callCancel interface, regardless of whether the userIDs parameter is empty or not, it is considered as canceling the invitation for all callees.

Since the old version of the ZIM SDK is not compatible with separate cancellation logic, if you need to retain the cancellation logic implemented using the old version of ZIM and also need to use the separate cancellation feature of the new version, please isolate the call functionality between the old and new versions of ZIM.

Usage in 2.16.0 version
Usage in old versions
// Cancel userIdA and userIdB separately
List<String> invitees = new ArrayList<>();
invitees.add("userIdA");
invitees.add("userIdB");
ZIMCallCancelConfig cancelConfig = new ZIMCallCancelConfig();
ZIM.getInstance().callCancel(invitees, "callID", cancelConfig, new ZIMCallCancelSentCallback() {
    @Override
    public void onCallCancelSent(String callID, ArrayList<String> errorInvitees, ZIMError errorInfo) {
        
    }
});;

// Cancel the entire call invitation, can be called successfully when none of the callees in the entire call have accepted    
List<String> invitees = new ArrayList<>();
ZIMCallCancelConfig cancelConfig = new ZIMCallCancelConfig();
ZIM.getInstance().callCancel(invitees, "callID", cancelConfig, new ZIMCallCancelSentCallback() {
    @Override
    public void onCallCancelSent(String callID, ArrayList<String> errorInvitees, ZIMError errorInfo) {

    }
});
