That's a feature of Android Studio introduced in the version 2.0. It quickly swaps new codes with old ones and enables us to see the result almost immediately. As side products of this process, IDE might produce some files, but you should not worry about them.
... Instant Run is a behavior for the Run and Debug commands that significantly reduces the time between updates to your app. Although your first build may take longer to complete, Instant Run pushes subsequent updates to your app without building a new APK, so changes are visible much more quickly. ...
