I am trying to get my app id from Telegram API by using the method register.saveDeveloperInfo, but I cannot find the way to do it.
I'm using de MTProto Java library.
This is what I had done by now:
- I made my own 
register.saveDeveloperInfoimplemmentation in Java. - I call the method with the corrects params (https://core.telegram.org/api/obtaining_api_id)
 - The method returns a true boolean but I have not received the sms with my app_id.
 - When I enter in my app section of the telegram web (https://core.telegram.org/myapp) shows the "Your app is not ready yet" message.
 
Anyway, I'm trying to use the app_id from the source code of the official client but I can't send or receive message.
Does anyone know how to do it or where can I find more information?
