hi i would like to know if it is possible to create a messaging system like whatsapp
tank you
WhatsApp is a freeware, cross-platform messaging and Voice over IP service owned by Facebook, Inc. It allows users to send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other media. Wikipedia
Can you do all of this with App Inventor 2 the way FAcebook does it? No.
Using App Inventor 2:
You can make an app that sends text messages easily but not voice messages. You can make voice telephone calls (but not video calls). You can share images and text using the CloudDB or FirebaseDB in real time and awkwardly share images. You can share user location using the LocationSensor and sending the coordinates of the user using CloudDB, FirebaseDB or by sending a Text message or an eMail (using ActivityStarter). You can also share information using your GoogleDrive and a Google Spreadsheet or share information you provide on your own server. You can use the Sharing component to share files etc. by linking to the real WhatsApp.
Someone else might have other ideas as how to create a messaging system like Whatsapp.
Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor’s Manual here in the AI2 free online eBook http://www.appinventor.org/book2 … the links are at the bottom of the Web page. The book ‘teaches’ users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .
Also look here http://kio4.com/appinventor/index.htm and here http://www.imagnity.com/tutorial-index/ for more tutorials.

Whatsapp uses their servers to do what it does. You might be able to make a parody of Whatsapp . If you want to create a similar app, get your own server, code using a professional Android compiler like Android Studio and be prepared to spend lots of money.

Hi,
If you can post this topic in Work For Hire section, then I could look into it because it requires many external stuffs also.

I’m glad you asked. There are many approaches to write an instant messaging app in App Inventor or its derivatives
