Easy to learn app development-3

Today, because there are so many courses, I can only learn Android at night. I thought about it. "Learning circle" is a platform for users to learn and communicate, so it should have basic chat functions. Take a look and learn some experiences. Today's programming time is not long, today I thought about what the "learning circle" should look like, and I had a basic idea. Then tomorrow ’s goal is to find some tutorials in this area to reserve knowledge.
