How many megs can you have in a game on Android?

My game is about 15 megs so far when I check the properties of the apk file on Windows, but when I check the size on the Android phone it shows 24 megs. Any explaination for this?
Also, When publishing the game is there a size limit? thanx

That is the expected difference (~9MB) if you use ‘Development Build’ (checkbox under Build Settings). In ‘Release Mode’ the difference should only be about 200KB on top of the size of the .apk file. The reason is that the binaries are extracted from the .apk during installation on the device.

The current size limit of the Android Market is 50MB.

On top of what Erique says quite a few Android devices have a 40MB application file size limit so bear that in mind too.

Just to add, I think there are some device specific limitations but here it says 50MB:

Also I’ve heard people say it won’t show up on some devices if its too big so watch out for that.
