[@olanikebaiyelo2168]

Well done. I enjoyed your presentation. One thing is puzzling. Where is the UI for the phone numbers where you send the chat to. How does your app know who to send the message to.

How can we know whom will the message be sent to? Because there should be an option to send to a particular person.

When a message is sent it will be visible to everybody who has the app. I will create a option to send to a particular person in my future tutorials.

I click send button, "TYPE HERE" text box should be erased. it is not erasing so what con I do

Did you put "TYPE HERE" as a hint of the textbox?

[@nandinitskb]

@@KrishnaRaghavendran yes,but what I wrote in the test box should erase when I click send button

[@KrishnaRaghavendran]

Inside "When Button2 Clicked" Block you need to add this block: drive.google.com/file/d/1Pg5JcDkRjn_cWNRTpgVJKyztG_iYLbHS/view?usp=sharing
Now after a message is sent, the textbox will be cleared.

[@gabrielblanch8847]

You are the best. Thanks a lot for your help! ☺
Do you know how could we do that appear the number of people there are online when we open the chat, please? (or other similar option).

[@KrishnaRaghavendran]

Sure, here are the steps to implement a feature in a chat app created using MIT App Inventor CloudDB that displays the number of online users:
Drag a CloudDB component from the Palette to the Viewer.
In the Blocks Editor, create a list variable called "OnlineUsers" and initialize it to an empty list.
When a user logs in or opens the app, add their username to the "OnlineUsers" list in the CloudDB by storing the updated list using the "StoreValue" block. You can use the "GetValue" block to get the current value of the "OnlineUsers" list, add the new username to the list, and then store the updated list back to the CloudDB using the "StoreValue" block.
When a user logs out or closes the app, remove their username from the "OnlineUsers" list in the CloudDB by storing the updated list using the "StoreValue" block. You can use the "GetValue" block to get the current value of the "OnlineUsers" list, remove the username from the list, and then store the updated list back to the CloudDB using the "StoreValue" block.
To display the number of online users in the app, use the "GetValue" block to get the current value of the "OnlineUsers" list from the CloudDB, and then use the "length" block to count the number of usernames in the list. You can display this number in a label or textbox in your app.

Yo, how did you get it to work from 2 different mobiles? I need to know because its for my school project please!?
