Delete channels

ChatUI includes built-in delete functionality in the channel long-press menu.

To customize the delete logic, use the nexconn public API.

Delete a specific channel

Remove the channel from the channel list (does not delete message content).

Kotlin

kotlin

val identifier = ChannelIdentifier(ChannelType.DIRECT, "user_001")
val channel = NCChatUI.createChannel(identifier)

channel.delete { result, error ->
  // result == true and error == null indicates success
}

Java

Java

ChannelIdentifier identifier = new ChannelIdentifier(ChannelType.DIRECT, "user_001");
BaseChannel channel = NCChatUI.createChannel(identifier);

channel.delete((result, error) -> {
    // result == true and error == null indicates success
});

Delete channels in batch

Kotlin

kotlin

val ids = listOf(
  ChannelIdentifier(ChannelType.DIRECT, "user_001"),
  ChannelIdentifier(ChannelType.GROUP, "group_001")
)

BaseChannel.deleteChannels(ids) { result, error ->
  // result == true and error == null indicates success
}

Java

Java

List<ChannelIdentifier> ids = Arrays.asList(
    new ChannelIdentifier(ChannelType.DIRECT, "user_001"),
    new ChannelIdentifier(ChannelType.GROUP, "group_001"));

BaseChannel.deleteChannels(ids, (result, error) -> {
    // result == true and error == null indicates success
});

tip

Deleting a channel does not automatically clear its message history. To remove messages, call the message delete API. For details, see Delete messages.
