Minimum knowledge for an android application?

Question

Python

What is the minimum knowledge needed to make an android application.
I'm thinking of doing it in Python, because some time ago I started learning it, and I want to practice somehow. I know that python is not quite right for android, but still.
What is its essence.
On the screen there are several buttons on which there is a picture and some kind of signature.
If you press a button, say "A", then the counter will count how many times it was pressed.
And then swipe somewhere or in the menu so that you can see how many times this or that button has been pressed.
It is also necessary that the data be saved when you exit the application or when you reboot / turn off the phone.

If you press a button, say "A", then the counter will count how many times it was pressed.
And then swipe somewhere or in the menu so that you can see how many times this or that button has been pressed.

You can't call it an app.

What is the minimum knowledge needed to make an android application.

My story: At the championship we were given a task - to make a gallery on Android. Up to this point, Android has not been studied at all. Before me was Android Studio, Java and 15 minutes per session to access the Internet. Took some time and went to google - "Java, create gallery". As a result, I made a gallery in 1.5 hours. I hope I explained clearly.
Now to the solution of the issue:
1) Android Studio + YaP Kotlin
2) Create a template project
2) Add button layouts (Button) and TextView to the XML
3) Create a counter in the Activity
4) Attach an OnClickListener to each button
5) In the handler, increase yours by one counter and overwrite text in TextView

I'm thinking of doing it in Python, since I started learning it some time ago

Here it is not necessary to push a python where it should not be. Yes, you can write on it, but you don't have to! Leave it to ML and the web. It was not developed for Android. Use programming languages ​​that are designed to solve a problem, not because you just started learning a language and want to practice it..

Answer 2

It will be difficult to write in python for android, but it is also possible.
I can even advise you to use this https://www.qpython.com/ and https://termux.com/
And write like everyone else. Kotlin will be easier than python.
