Now I am learning JAVA. What also I should learn before downloading and working with Android Studio .Thanx for answer ))

Question

JAVA

Answer 1

Someone may suggest you to learn xml but I would personally recommend just to start making some simple apps and learning Android Studio side by side as you are learning java. The reason is that in recent updates of android studio now most of the work that was in past done by using xml can be now done with out using xml.So, in short yes you need not to learn anything and you can take tutorial from udemy academy to learn android studio.
Best Of Luck!

Answer 2

first complete your java course then go for android
