Dooood! We must get deodexed!
I'm aware of this ∙∙∙
"Currently the apps are Odexed, so they can't be conventionally installed or resigned. And the current iteration of Baksmali doesn't work with the deodexing process. I'm sure somebody will be able to do so or Baksmali will get an update to work with it. But it'll take some time, a lot of great things coming for Android nonetheless."
∙∙∙ but unaware of the status.
