What is the difference between Smack and aSmack?

Question

I am not able to use Smack on Android whereas aSmack works perfectly? When compared the source code it looks somewhat similar, where does the difference comes from?

Answer 1

It modifies Smack to allow it to work on Android.

I am not sure of what those changes are, with the exception of altering the ProviderManager mechanism so that it can load the smack.providers XML file from an Android friendly directory. By default Smack loads this from its own resource directory, which is not reachable in Android.
