Why are my apps so different in size? / iOS 34mb vs Android50mb

As the title suggests… Why are my compiled google and apple apps so different in size?

The iOS version is 34mb and the Android version is 50mb

I assume that is has something to do with the .pngs and if so, how can I get those to shrink?

Thanks!

I don’t have an official answer, but my guess would be that the iOS version has moved some features to plugins, but they still remain part of core for the Android apk.

As an example, for the previous public release of Corona, Facebook for iOS was a plugin, but was still part of the core code for Android. So if you weren’t using Facebook at all in your app, the file size would be smaller on iOS.

That’s my theory anyway…

There are a couple of factors causing this.  First, on iOS things like SQLite are part of the OS.  They have to be included with Corona’s Core on Android.  The executable will always be a few megabytes larger on Android.  Next Apple runs pngcrush on .PNG’s to squeeze them as much as they can.  This could also add up to a few megabytes difference.

Thanks for the info!!

Can I use the crushed .PNGs on the android version!?

That would solve all my size problems I think!!

There are other PNG compressors out there.  You’re mileage may vary.
