JTelegramBot
Author: DonManfred (Wrapper)
Version: 0.31

Setup:
- To get the Example running you first need to adapt the Initialize line with your Bots Name and ApiToken.
Code: 
Sub AppStart (Args() As String)
    jtb.Initialize("JTB","yourbotname","youtbottoken")
    glmap.Initialize
    jtb.startAsync
    StartMessageLoop
End Sub
- The Example is using Static Filenames for the Document, MP3, Photo, Sticker send.
Make sure to adapt the path and Filenames to match Files you want to use.

Code: 
    If message.Text = "/buttons" Then
        Dim mark As InlineKeyboardMarkup
        mark.initialize(jtb.CreateDummyKeyboard)
        Dim buttons As Message = jtb.sendMessage(jtb.byId(from.Id),"Click the Button!","MARKDOWN",False,False,message.MessageId,mark)
        glmap.Put(buttons.MessageId,buttons)
    else If message.Text = "/location" Then
        jtb.sendChatAction(jtb.byId(from.Id),jtb.ChatActionFIND_LOCATION)
        jtb.sendLocation(jtb.byId(from.Id),50.8337006,6.441118,False,message.MessageId,Null)
    else If message.Text = "/url" Then
        jtb.sendMessage(jtb.byId(from.Id),"[jTelegramBot Thread](https://www.b4x.com/android/forum/threads/jtelegrambot.103778/#post-650611)","MARKDOWN",False,False,message.MessageId,Null)
    else If message.Text = "/plainurl" Then
        bld.sendMessage(chat.Id,"Link without Preview [jTelegramBot Thread](https://www.b4x.com/android/forum/threads/jtelegrambot.103778/#post-650611)",message.MessageId,False,True,Null,jtb.parsemodeMARKDOWN)
    else If message.Text = "/text" Then
        jtb.sendMessage(jtb.byId(from.Id),$"Testtext <b>Bold</b>, <i>Italic</i>
    new row..."$,"HTML",True,False,message.MessageId,Null)
    else If message.Text = "/document" Then
        jtb.sendChatAction(jtb.byId(from.Id),jtb.ChatActionUPLOAD_DOCUMENT)
        jtb.sendDocument(jtb.byId(from.Id),jtb.MediaByFile(File.DirApp,"mydocument.zip"),"DocumentCaption",False,message.MessageId,Null)
    else If message.Text = "/photo" Then
        jtb.sendChatAction(jtb.byId(from.Id),jtb.ChatActionUPLOAD_PHOTO)
        jtb.sendPhoto(jtb.byId(from.Id),jtb.MediaByFile(File.DirApp,"myimage.png"),"DocumentCaption",False,message.MessageId,replbld.forceReply)
    else If message.Text = "/audio" Then
        jtb.sendChatAction(jtb.byId(from.Id),jtb.ChatActionUPLOAD_VIDEO)
        jtb.sendAudio(jtb.byId(from.Id),jtb.MediaByFile(File.DirApp,"myaudio.mp3"),223,"Fleedwood Mac","Eyes of the World",False,message.MessageId,replbld.forceReply)
    else If message.Text = "/sticker" Then
        jtb.sendSticker(jtb.byId(from.Id),jtb.MediaByFile(File.DirApp,"mysticker.webp"),False,message.MessageId,Null)
    else If message.Text = "/start" Then
        jtb.sendMessage(jtb.byId(from.Id),$" Hello ${chat.Username}
`Command   | Result
----------|-------------------------
/location | Returns a Locationobject
/document | Returns a Document
/photo    | Returns a Photo
/audio    | Returns a Audiofile
/url      | Returns a URL with Preview
/plainurl | Returns a URL without Preview
/buttons  | Shows some buttons To Click on
`
Thank you For choosing Me :-)"$,"MARKDOWN",False,False,message.MessageId,Null)

In this example you need to replace the following Filereferences:
- mydocument.zip
- myimage.png
- myaudio.mp3
- mysticker.webp

1. You should always create a new thread in the b4j questionsforum for any Question you have. Just make sure to note that you are using jTelegramBot library version xx

See my comment from #1!

2. Seems it is not implemented in the Github project. I could not find anything about Pinning in the Sources.
 
Hi, sorry in advance, I'm reading a lot of posts and I got confused, what I need to install and how to start using this library?
 
As written in #1 of this thread you should create a new Thread for any question/issue you have in the Questionsforum.

The answer is:
An example is attached to the 1st post,
the library is there too. You need to copy it to the additional libs folder.
Also note to download the additional files (See the DOWNLOAD link in #1) and copy them to the additional libs folder too.

Can bot read messages from Privat Telegram channel (only read channel)?
Click to expand...
1. You should ALWAYS(!) create a new thread in the Questionsforum for any question/issie you have! Posting to existing threads is a Mistake.
2. If the bot is added to a channel then he gets all Messages in this channel. If you send a private message to the bot the bot can read this private message and respond to it using the channel id.
 
Hi
what is message.MessageId ?

DonManfred said:
Next version will have a possibility to change the InlineKeyboard. In the 1st version only a dummykeyboard is generated inside the library which could not be changed.

Code: 
        Dim ibld As InlineKeyboardButtonBuilder
        Dim mark As InlineKeyboardMarkup
        mark.initialize(ibld.Initialize.newRow.newButton("1").withCallbackData("BTN1").newButton("2").withCallbackData("BTN2").newButton("3").withCallbackData("BTN3").newRow.newButton("Google").withUrl("https://www.google.com").newRow.build)
        Dim buttons As Message = jtb.sendMessage(jtb.byId(from.Id),"Click the Button!","MARKDOWN",False,False,message.MessageId,mark)

Hello @DonManfred , Firstly thank you for wrapping this library. I have been playing around with this for the last 3 days and I believe there are a lot of things that could be done using a bot.

Question if I may ask. the Original library is about 4 years since any changes (not complaining :)) and I am not sure if the Author is maintaining it. I would love to integrate this into my application. Would you still recommend using it for a long term client-facing production application?

Thank you for the source, just checking if it is the latest?

Have a nice day!
 
in v 0.31
bad class file: C:\Program Files (x86)\Anywhere Software\B4J\libraries\jtelegrambot.jar(de/donmanfred/JTBwrapper.class)
class file has wrong version 55.0, should be 52.0
Please remove or make sure it appears in the correct subdirectory of the classpath.

help please
 
Hello, I tried your bot in Telegram, is it normal like this please? No response from the bot. It's the first time I used Telegram.

The Bot example does not have any UI.
You need to check the log for any events which are raised.

Based on the Screenshot the messages did arrived at the Bot. I expect it to be a Screenshot from Telegramclient.

Run the Bot from the Ide and monitor the logs, see what message is coming in and how your Bot is handling this Message.

I can not help more as you did not provided any useful informations.

Away from that you should ALWAYS create a new Thread for any Question/Issue you have in the Quetionsforum.
Make sure to post all relevant code from your Bot to see what you are doing and how.
Best is to upload a small project (without your token)....
