How and on what to write an android application?

Question

Android

I would like to write an application for android with a chat and the ability to track the interlocutor (such as zenli), purely to communicate with friends and relatives. After looking at a couple of articles on the Internet, I realized that most of the applications were written in java, kotlin using android studio. But I heard that telegram is written in c ++, so write what tools are used to develop android applications in c ++, or at least push in the right direction.
Thanks in advance!

Write in Java in Android Studio and don't show off because For your task, this is the best option. The choice of C ++ should be due to some reasons, for example, the presence of libraries that are not in Java, or something else significant.

Answer 2

Qt

Answer 3

Java, Android SDK. Back in the language that is closer to you.
Do not chase cross-platform, for most applications there are too many platform features to consider, it is often easier to make native applications for iOS and Android than to suffer due to cross-platform limitations. And again, more than half of the functionality of modern applications is the server side.
