This is a related question I asked last week....My previous question
I downloaded VS 2015 and I can add Xamarin to it for app development.
(This is a general question and there might not be a definite answer to it)...I was reading this article Article
And mobile development is on the list. What do companies who hire app developers look for?...
a. To know Java (or Objective C)?
b. Use tools like Xamarin or PhoneGap and use C# (in my case)? (like VS 2015)
I have a Java developer coworker who does Android app development. He says learning Java to do app development is the way to go.
