Google has increased the maximum size of Android apps from 50MB to a whopping 4GB according to a post on the Android Developers blog.
"Android applications have historically been limited to a maximum size of 50MB. This works for most apps, and smaller is usually better - every megabyte you add makes it harder for your users to download and get started," software architect Tim Bray wrote on the blog. "However, some types of apps, like high-quality 3D interactive games, require more local resources."
The Android Package files or APK will still be limited to 50MB but developers will now have the option of attaching two more 2GB expansion files.
This means that Android Market (rather than the developers) will be hosting the files which may decrease costs and should allow users to see the total size of the application before purchasing and installing it.
Another useful addition is the fact that for most devices, Android Market's 15-minutes refund period won't start until an app is fully downloaded.
Whether this is going to encourage developers to code efficiently in order to reduce file sizes, we're unsure, however, the 4GB limit may mean that Android device makers may finally be forced to increase the amount of onboard storage.
