Maybe adding Kotlin would be a better idea, otherwise I'm sure knowing your Java will give you a large headstart in Android development so I don't think adding an Android course would be really (note, I said really) necessary. But I wouldn't mind if they do though. ☺
Google offers free tutorials on andoid. Also the Android SDK is a free download. I am working through some of it now. I just made my first app that displays the text "Holy S*!t, it worked". I know .... sounds lame, but I was impressed. Hey.... you have to start somewhere.

also writing a q&a post won't make it go through SoloLearn's office : you need to send them an email...
I'd certainly like to see an Android course in here. Since XML is a key part of Android app development, maybe SoloLearn should add an XML course so that developers can get a feel for it.
Yes, they should also add Kotlin, but I think that it would be good to have both an XML and Java tutorial, and a Kotlin tutorial. Great idea for Kotlin.
