We can't send messages in here so

Question

If we want to make a messaging app like whatsapp, how can we make it?

Which programming languages we can use to make it? How we can buy and administrate servers?

Any experienced person in here? Can u explain? please.

Answer 1

with appinventor there is the fireBaseDB component, that is used to connect with a firebase server

if you make something like
(pseudo code)
forever do{
if( server.hasNewMessage){
print message
}}

Answer 2

then you can make a textbox with a button that when clicked sent the text inside the textbox in the server

Answer 3

but now we have a problem: we send a message but to the entire world so you have to make something to redirect the message to the correct client

Answer 4
