Delete messages

The Nexconn SDK supports two ways to delete messages:

• Delete for me: Remove messages from the current user's history only.
• Delete for everyone: Remove a message from all participants' history (recall).

Delete for me

Use deleteMessagesForMe() to remove messages from the current user's history.

Kotlin

kotlin

val channel = DirectChannel("userId")

channel.deleteMessagesForMe(listOf(message)) { error ->
    if (error == null) {
        Log.d("Delete", "Message deleted")
    } else {
        Log.e("Delete", "Failed: ${error.message}")
    }
}

// Delete multiple messages
val messages = listOf(message1, message2, message3)
channel.deleteMessagesForMe(messages) { error ->
    if (error == null) {
        Log.d("Delete", "Batch delete succeeded")
    }
}

Java

Java

DirectChannel channel = new DirectChannel("userId");

List<Message> messages = Collections.singletonList(message);
channel.deleteMessagesForMe(messages, new ErrorHandler() {
    @Override
    public void onResult(NCError error) {
        if (error == null) {
            Log.d("Delete", "Message deleted");
        } else {
            Log.e("Delete", "Failed: " + error.getMessage());
        }
    }
});

Delete for everyone

Use deleteMessageForAll() to recall a message. All participants see the message as deleted.

Kotlin

kotlin

val channel = DirectChannel("userId")

channel.deleteMessageForAll(message) { updatedMessage, error ->
    if (error == null) {
        Log.d("Recall", "Message deleted for everyone")
    } else {
        Log.e("Recall", "Failed: ${error.message}")
    }
}

Java

Java

DirectChannel channel = new DirectChannel("userId");

channel.deleteMessageForAll(message, (updatedMessage, error) -> {
    if (error == null) {
        Log.d("Recall", "Message deleted for everyone");
    }
});

Parameters

deleteMessagesForMe

Parameter	Type	Description
messages	List<Message>	The messages to delete.
handler	ErrorHandler	The completion callback.

deleteMessageForAll

Parameter	Type	Description

Important notes

• deleteMessagesForMe only affects the current user's history.
• deleteMessageForAll recalls the message for all participants.
• Recall typically has a time limit (e.g., 2 minutes), configurable on the server.
