Should I still learn deprecated classes on android studio as a beginner?

[Codebreaker0101]

I'm learning Android Development for the last 6 months and recently I've notice that some of my framework classes have been deprecated, I'm learning android studio from Udacity.com they have a lot of android free courses to choose from, all of their android courses were publish 6 years ago, should I continue learning their free course even if they used some deprecated classes like loaders, asynctask, etc I've learned a lot from their courses should I still continue tackling their courses?

It is recommended to check the official Android developer website.

Android has changed a lot in the past six years; I'm not sure it would be worth the effort of learning a bunch of deprecated classes since you shouldn't be using them anymore. I'd recommend looking for more up-to-date training material.
