Users can delete any message they themselves have sent. An error is returned if a user attempts to delete messages sent by other users. Also channel operators can delete any messages in a channel.
// The BASE_MESSAGE argument below indicates a BaseMessage object to delete.
channel.deleteMessage(BASE_MESSAGE) { e ->
if (e != null) {
// Handle error.
}
// The message is successfully deleted from the channel.
}
After a message has been deleted, the onMessageDeleted() method in the channel event handler is invoked on all users' devices including the device where the message was deleted.
SendbirdChat.addChannelHandler(
UNIQUE_HANDLER_ID,
object : OpenChannelHandler() {
override fun onMessageDeleted(channel: BaseChannel, messageId: Long) {
// ...
}
// ...
}
)
SendbirdChat.addChannelHandler(
UNIQUE_HANDLER_ID,
object : GroupChannelHandler() {
override fun onMessageDeleted(channel: BaseChannel, messageId: Long) {
// ...
}
}
)
