My iPA is much larger than my apk

Hello,

I have two problems: 1. My apk size is 25 mb while in playstore it is 50 mb 2. My iap size is 285 mb (on the appstore)

Edit:

I have read about this problem in many forums and in the unity manual. This is the first time I'm publishing unity project on iOS and I have some issues with the stripping and the xml file that controll. I would vey appreciate if some one can help me use this stripping feature.

Thank you for you time
