Author Konstantin Vorobyev has created an Android client with Syncing and many other features.
Taskwarrior for Android has an embedded copy of Taskwarrior, and so inherits all the behaviors. Take a look at Taskwarrior for Android on Google Play.
Taskwarrior for Android is open source, and can be found on bitbucket.org/kvorobyev/taskwarriorandroid.
