Delete messages in a batch

Parameters

DeleteMessagesReq request = new DeleteMessagesReq(
    true,
    conversationID,
    selectedClientMsgIDs.toArray(new String[0])
);

messageManager.deleteMessages(request, new OnBase<String>() {
    @Override
    public void onSuccess(String data) {
        // The deletion request has completed
    }

    @Override
    public void onError(int code, String error) {
        // Handle the failure
    }
});

With isSync set to false, the operation deletes the current device's copy and the current account's server-side record. With true, it also requests deletion synchronization to the account's other clients. It does not delete copies held by other conversation members or display a revocation notice.

The success callback means that the deletion request has completed. When synchronization is enabled, it does not mean that other clients have already received the event or updated their interfaces.

When synchronization is enabled, other clients can receive the deleted message through OnAdvanceMsgListener.onMsgDeleted:

@Override
public void onMsgDeleted(Message message) {
    // message is the deleted message.
}
