Android App Dev

Question

I'm planning to make some Android apps. Nothing too sophisticated, simple apps. I know the basic of Ruby, and I know there's Ruby Motion, but I found it a bit hard to understand how it works. So now I'm learning Kotlin and XML, is those languages enough to my purpose?

Answer 1

Obviously. You need to know a database too, sqlite or firebase are good, and you need to understand the Application life cycle(on create, start, pause..).

Intents, UI, fragments, layouts, maps, REST are important to know. Things like animations aren't obligatory unless you have a case to use them.
