Additional Message Filtering

Filter messages by category, type, timestamp, tags, and other parameters using MessagesRequest in the CometChat Android SDK.

AI Integration Quick Reference

// Build filtered message request
val messagesRequest = MessagesRequestBuilder()
    .setUID("user_uid")                    // User conversation
    .setLimit(50)                          // Max 100 per request
    .setCategories(listOf("message"))      // Filter by category
    .setTypes(listOf("text", "image"))     // Filter by type
    .setUnread(true)                       // Only unread messages
    .hideDeletedMessages(true)             // Exclude deleted
    .hideReplies(true)                     // Exclude threaded messages
    .build()

// Fetch messages
messagesRequest.fetchNext(callback)
messagesRequest.fetchPrevious(callback)

The MessagesRequest class fetches messages based on various parameters using the Builder design pattern.

To fetch messages:

1. Create a MessagesRequestBuilder object
2. Set your desired parameters
3. Call build() to get a MessagesRequest object
4. Call fetchNext() or fetchPrevious() to retrieve messages

Method	Description
fetchNext()	Returns messages after the specified parameters
fetchPrevious()	Returns messages before the specified parameters

Messages are paginated with a maximum of 100 per request. Call fetchPrevious()/fetchNext() repeatedly on the same object to get subsequent pages.

Number of messages fetched

Set the number of messages to fetch per request using setLimit(). Maximum is 100.

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
.setLimit(50)
.setUID(UID)
.build();

Java (Group)

String GUID = "cometchat-guid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
.setLimit(50)
.setGUID(GUID)
.build();

Kotlin (User)

val UID = "cometchat-uid-1"

val messagesRequest = MessagesRequestBuilder()
  .setLimit(50)
  .setUID(UID)
  .build()

Kotlin (Group)

val GUID = "cometchat-guid-1"

val messagesRequest = MessagesRequestBuilder()
  .setLimit(50)
  .setGUID(GUID)
  .build() 

Messages for a user conversation

Use setUID() to fetch messages between the logged-in user and a specific user.

Java

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
.setUID("cometchat-uid-1")
.setLimit(50)
.build();

Kotlin

val messagesRequest = MessagesRequestBuilder()
  .setUID("cometchat-uid-1")
  .setLimit(50)
  .build()

Messages for a group conversation

Use setGUID() to fetch messages from a group. The logged-in user must be a member of the group.

Java

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
.setGUID("cometchat-guid-1")
.setLimit(50)
.build();

Kotlin

val messagesRequest = MessagesRequestBuilder()
  .setGUID("cometchat-guid-1")
  .setLimit(50)
  .build()

Messages before/after a message

Use setMessageId() to fetch messages before or after a specific message ID. Use fetchNext() to get messages after, or fetchPrevious() to get messages before.

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setMessageId(100)
  .setLimit(50)
  .setUID(UID)
  .build();

Java (Group)

String GUID = "cometchat-guid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setMessageId(100)
  .setLimit(50)
  .setGUID(GUID)
  .build();

Kotlin (User)

val UID = "cometchat-uid-1"

val messagesRequest = MessagesRequestBuilder()
  .setMessageId(100)
  .setLimit(50)
  .setUID(UID)
  .build()

Kotlin (Group)

val GUID = "cometchat-guid-1"

val messagesRequest = MessagesRequestBuilder()
  .setMessageId(100)
  .setLimit(50)
  .setGUID(GUID)
  .build()

This method can be combined with setUID() or setGUID() to fetch messages around a specific message in a conversation.

Messages before/after a given time

Use setTimestamp() with a Unix timestamp to fetch messages before or after a specific time.

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setTimestamp(1512687363)
  .setLimit(50)
  .setUID(UID)
  .build();

Java (Group)

String GUID = "cometchat-guid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setTimestamp(1512687363)
  .setLimit(50)
  .setGUID(GUID)
  .build();

Kotlin (User)

val UID = "cometchat-uid-1"

val messagesRequest = MessagesRequestBuilder()
  .setTimestamp(1512687363)
  .setLimit(50)
  .setUID(UID)
  .build()

Kotlin (Group)

val GUID = "cometchat-guid-1"

val messagesRequest = MessagesRequestBuilder()
  .setTimestamp(1512687363)
  .setLimit(50)
  .setGUID(GUID)
  .build() 

This method can be combined with setUID() or setGUID() to fetch messages around a specific time in a conversation.

Unread messages

Use setUnread(true) to fetch only unread messages.

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setUnread(true)
  .setLimit(50)
  .setUID(UID)
  .build();

Java (Group)

String GUID = "cometchat-guid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setUnread(true)
  .setLimit(50)
  .setGUID(GUID)
  .build();

Kotlin (User)

val UID = "cometchat-uid-1"

val messagesRequest = MessagesRequestBuilder()
  .setUnread(true)
  .setLimit(50)
  .setUID(UID)
  .build()

Kotlin (Group)

val GUID = "cometchat-guid-1"

val messagesRequest = MessagesRequestBuilder()
  .setUnread(true)
  .setLimit(50)
  .setGUID(GUID)
  .build()

This method along with setGUID() or setUID() can be used to fetch unread messages for a particular group or user conversation respectively.

Exclude messages from blocked users

Use hideMessagesFromBlockedUsers(true) to exclude messages from users you’ve blocked. Default is false.

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .hideMessagesFromBlockedUsers(true)
  .setUID(UID)
  .setLimit(50)
  .build(); 

Java (Group)

String GUID = "cometchat-guid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .hideMessagesFromBlockedUsers(true)
  .setGUID(GUID)
  .setLimit(50)
  .build();

Kotlin (User)

val UID = "cometchat-uid-1"

val messagesRequest = MessagesRequestBuilder()
  .hideMessagesFromBlockedUsers(true)
  .setUID(UID)
  .setLimit(50)
  .build()

Kotlin (Group)

val GUID = "cometchat-guid-1"

val messagesRequest = MessagesRequestBuilder()
  .hideMessagesFromBlockedUsers(true)
  .setGUID(GUID)
  .setLimit(50)
  .build()

This also works in group conversations where both users are members.

Updated and received messages

Use setUpdatedAfter() with a Unix timestamp to fetch messages that were sent or updated after a specific time. Updated messages include those marked as read/delivered, edited, or deleted.

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setUpdatedAfter(1514321321)
  .setLimit(50)
  .setUID(UID)
  .build();

Java (Group)

String GUID = "cometchat-guid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
  .setUpdatedAfter(1514321321)
  .setLimit(50)
  .setGUID(GUID)
  .build();

Kotlin (User)

val UID = "cometchat-uid-1"

val messagesRequest = MessagesRequestBuilder()
  .setUpdatedAfter(1514321321)

  .build()

Kotlin (Group)

val GUID = "cometchat-guid-1"

val messagesRequest = MessagesRequestBuilder()
  .setUpdatedAfter(1514321321)
  .setLimit(50)
  .setGUID(GUID)
  .build()

Useful for syncing messages with a local database — fetch only what’s changed since your last sync.

Updated messages only

Use updatesOnly(true) with setUpdatedAfter() to fetch only updated messages (not newly received ones). This method must be used together with setUpdatedAfter().

Java (User)

String UID = "cometchat-uid-1";

MessagesRequest messagesRequest = new MessagesRequest.MessagesRequestBuilder()
