Easy application on Android — how?

Colleagues, the environment in which you can collect lightweight app for Android?
In Android Studio shows a little practice - a few megabytes.
Comes to Google Play e software in a few kilobytes - than it collected?!

I hope clearly formulated question %)

"In Android Studio shows a little practice - a few megabytes."
And where do you find these practices?
I have an app in the 300Kb out.

If you do not drag in the project third-party packages with lots of resources which is not clear in what situation are used, then the application is compact.
