Least Knowledge required for Mobile Apps Development

Most of the time, I get the same repeated question, 'What are the basic skills required to start learning Mobile Apps Development?'.
So, I thought to answer these questions concisely here:
Least Required Knowledge:

• Basic problem-solving skills
• Basic Programming concepts like variables, control structures (if-else and switch case, etc.) and loops, etc.
• Basic Object-Oriented concepts like Classes, Objects, and Inheritance, etc
• Little knowledge of different data structures like Lists(Arrays), Maps (Dictionaries) and custom data structures
• Bug hunting and debugging
• Little bit knowledge of Database
• And the most important one, the thirst for learning new things.

I hope these things help a little bit deciding when you should start with Mobile Apps Development or what are the basics you need to cover before starting Mobile Apps Development.
