These are still just technologies! And it does not give you edge over other developers....
Android, all languages - they are just tools and should be treated as tools only - no worshipping etc.
What matters more is what I create with these tools.
After all, do you pay too much attention to hammer/nails or to the end result - a table you can make with these tools? You certainly should keep them sharp/durable, but think about what you can do with them.
So, from now on, I change my attitude to all languages/compilers/frameworks etc - I don't crave to master all of them completely - just enough so that i can get my projects done
