Problem

After recent TDLib API changes, Example.java fails to compile with the following errors:

Root cause

The InlineKeyboardButton constructor was updated to include new parameters iconCustomEmojiId (long) and style (ButtonStyle), but Example.java was not updated accordingly.

Old signature:

InlineKeyboardButton(String text, InlineKeyboardButtonType type)

New signature:

InlineKeyboardButton(String text, long iconCustomEmojiId, ButtonStyle style, InlineKeyboardButtonType type)

Additionally, InlineKeyboardButtonTypeUrl now requires an explicit url parameter instead of being no-arg:

Old: new InlineKeyboardButtonTypeUrl()
New: new InlineKeyboardButtonTypeUrl(String url)

Similarly, SendMessage constructor gained a new MessageTopic topicId parameter:

Old:

SendMessage(long chatId, InputMessageReplyTo replyTo, MessageSendOptions options, ReplyMarkup replyMarkup, InputMessageContent inputMessageContent)

New:

SendMessage(long chatId, MessageTopic topicId, InputMessageReplyTo replyTo, MessageSendOptions options, ReplyMarkup replyMarkup, InputMessageContent inputMessageContent)

Changes

example/java/org/drinkless/tdlib/example/Example.java — method sendMessage:

  1. InlineKeyboardButton — added 0 for iconCustomEmojiId and null for style (default values, preserving existing behavior).
  2. InlineKeyboardButtonTypeUrl — now passes the URL string explicitly.
  3. SendMessage — added null for the new topicId parameter.

This has already been fixed in the private TDLib version, which will become publicly available with the upcoming Telegram update.

Can we merge these changes now so that the TDLib build passes successfully? When a new version of TDLib is released, my changes will be overwritten
