I’m working on an Android application and I want to have tabs like the old YouTube app. The concept for the layout of the app is something like this:

The idea here is that you can quickly switch between different types of input panes with the tab and that the input preview is above them. Now, I just found out that the introduction of tabs in the action bar has deprecated these types of tabs at the same time.
This is understandable, but I think changing this part of the layout will greatly affect the functionality of my app, because there’s not really an alternative.
Would it be okay in this case to use the deprecated tab facilities anyway?
The tab-related features may be deprecated (and that functionality might someday stop working) but that does not stop you from implementing tabs by hand in a way that will keep working as long as the functionality you build them on continues to do approximately the same thing.
Perhaps of more concern would be the push away from that style of interface – but then it’s a push, not a mandate.
