Upgrading from v1.x to v2 is fairly simple. Below are the major changes that are released as a part of CometChat Pro v2.

​
Initialization

The CometChat.init() method now takes an additional parameter. This parameter is an object of the AppSettings class. This object can be created by using the AppSettingsBuilder class. The AppSettings class provides CometChat with the below 2 details:
  1. Region: The region of your app
  2. Presence Subscription
  • Java
// v1.x

CometChat.init(this, appID, new CometChat.CallbackListener<String>() {
  @Override
  public void onSuccess(String successMessage) {
    Log.d(TAG, "Initialization completed successfully");
  }
  @Override
  public void onError(CometChatException e) {
    Log.d(TAG, "Initialization failed with exception: " + e.getMessage());
  }
});


// v2.0

AppSettings appSettings=new AppSettings.AppSettingsBuilder().subscribePresenceForAllUsers().setRegion("eu").build();

CometChat.init(this, appID,appSettings, new CometChat.CallbackListener<String>() {
  @Override
  public void onSuccess(String successMessage) {
    Log.d(TAG, "Initialization completed successfully");
  }
  @Override
  public void onError(CometChatException e) {
    Log.d(TAG, "Initialization failed with exception: " + e.getMessage());
  }
});

​
Text Message Constructor

Since the only possible valid value the messageType parameter could take in the constructor was CometChatConstants.MESSAGE_TYPE_TEXT, we have removed the messageType parameter from the TextMessage constructor.
  • Java
// v1.x

TextMessage textMessage = new TextMessage(receiverID, messageText, messageType, receiverType);


// v2.0

TextMessage textMessage = new TextMessage(receiverID, messageText, receiverType);

​
Mark a Message as Read

In v1.x, for marking the messages as read, every message had to marked as read individually using the CometChat.markMessageAsRead() which took the entire message object as the input parameter. Starting v2.0, the method name has been changed to markAsRead() which takes the messageId ,receiverId, and receiverType as input. This method, will mark all the messages as read. For more information, please check the mark messages as read guide.
  • Java
// v1.x

CometChat.markMessageAsRead(message);

// v2.0

CometChat.markAsRead(messageId, receiverId, receiverType);

​
Retrieve List of Friends

In v1.x to fetch only friends, you had to enable the Show only friends setting in the CometChat Dashboard. Starting v2.x, we have added a method in the UsersRequestBuilder to fetch only friends. This method accepts boolean and fetches only friends if it is set to true else it fetches all the users. By default it is set to false. For more information, please check the retrieve list of users guide.
  • Java
//v2.x

UsersRequest usersRequest = new UsersRequest.UsersRequestBuilder()
.setLimit(limit)
.friendsOnly(true)
.build();
