Now that instant apps are a thing (and a great thing, in my opinion), I was wondering if there is a way to actually being able to download certain parts of your app (modules) in order to reduce the initial size of the APK.
For example, in my app I have a module that relies on a 3rd party library that increases the size of the APK in around 15 MB, and it only applies to certain users, so I would prefer to not to include that functionality in the final APK and make it optional.
So far, while this looks very similar to Instant Apps, I haven't been been able to find a solution to this problem, and I totally believe that many apps could benefit from something like this.
