How to make android apps of low size?

Question

I was doing a little project thing for my school...

I made a simple calculator app...with simple mathematics operations... And when the apk file is created and installed, it was consuming the memory space of more than 700 kb in the phone. While in the android market(play store), there are just similar apps which are of low sizes and are taking memory space of less than 500. I was creating app in eclipse...

Will somebody plz help me out with this that how they do make apps of simple lower size.??

Answer 1

The smallest APK I created is ~35kB. Size increases dramatically with the included assets. Check the size of your /res, /assets and, if you have it, /raw folders. The APK size will be larger than those three combined. Further, any included lib counts, and adds bulk, even (and especially) the compatibility library, if you use it.
