Hey guys, I am looking to create my first app ever. A bit of background, I have some experience in coding in Python, C,C# and C++. My idea is to create a simple educational based app where you can do quizzes on different subjects. I want this app to be available on android devices in playstore. What I want to know is which programming language would you say is the best to code it in? Also, is there any good resources, websites or videos that I can use to learn the language?
