What is the difference between Smack and aSmack?

问题:

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?

What is the difference between Smack and aSmack?

回答1:

Smack < 4.1 does not work on Android, mostly because of APIs missing on Android (e.g. most of the javax APIs). That is the reason the aSmack build environment was born. It is a way to modify Smack so that it can be used on Android.

Besides many minor changes the biggest changes are

1. Disabling XMPP SASL auth methods that are not supported on Android
2. Using apache harmony for SASL instead of the javax API

Make sure to read the README and and init the relevant code before doing any XMPP related actions.

As the project description states, ASmack adds a set of patches to regular Smack. Check this conversation for further details.

You can see how things are done in talkmyphone. I think they are using smack with android.

回答4:

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.
