Why Android App Size Is Increasing After Publishing On Market?

I have published my app on android market recently. It is showing the app size as 5.4MB whereas actual apk size is 2.8MB. Why it is showing 2MB extra? What should i do to restrict

Solution 1:

Your app size is increased because you on your Copy Protection Option ON in publishing option. Market needs extra space to store those security related information.

Helps prevent copying of this application from the device. Increases the amount of memory on the phone required to install the application.
