Delete a message for everyone

The Nexconn SDK supports deleting a sent message for everyone. After deletion, the message is marked as deleted for all participants.

tip

• Use deleteMessageForAll() to delete a message for everyone.
• Only successfully sent messages can be deleted.
• Set your own time limit (e.g., within 2 minutes).

Listen for message deletion events

Use MessageHandler to listen for message deletion events.

Kotlin

kotlin

NCEngine.addMessageHandler("myHandler", object : MessageHandler {
    override fun onMessageDeleted(event: MessageDeletedEvent) {
        event.messages.forEach { message ->
            Log.d("Recall", "Message ${message.messageId} was recalled")
        }
    }
})

Java

Java

NCEngine.addMessageHandler("myHandler", new MessageHandler() {
    @Override
    public void onMessageDeleted(MessageDeletedEvent event) {
        for (Message message : event.getMessages()) {
            Log.d("Recall", "Message " + message.getMessageId() + " was recalled");
        }
    }
});

Delete a message

Use deleteMessageForAll() to delete a message for everyone. Pass the Message object directly.

Kotlin

kotlin

val channel = DirectChannel("userId")

// Basic recall
channel.deleteMessageForAll(message) { updatedMessage, error ->
    if (error == null) {
        Log.d("Recall", "Message recalled")
    }
}

Java

Java

DirectChannel channel = new DirectChannel("userId");

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

Parameters

deleteMessageForAll

Parameter	Type	Description
message	Message	The message to delete.
handler	OperationHandler<Message?>	Callback returning the updated message on success.

Important notes

• Deletion affects all participants' message history.
• Implement your own time limit (e.g., 2 minutes).
• Use isAdmin to allow admins to delete other users' messages.
• Recipients receive the onMessageDeleted callback on deletion.
