Can "v17 Leanback Library"(android Tv Support Library) Support 2.x Or 4.x Device?

I have some trouble when develop on TV device, Can 'v17 leanback library' support 2.x or 4.x device? 'v17 leanback library' is a TV Support Libraries.It request the app's minSdkVer

Solution 1:

This seems to be quite an old question and since the Lollipop announcement, I guess it's easy to say that yes, since the Leanback API has been integrated in a support library.

compile 'com.android.support:leanback-v17:21.0.0'

I actually had some fun implementing the samples and my custom apps using it on Android KitKat and it all works like a charm.

Interesting to say though, you won't have the nice transitions as you can see them on Lollipop.

Edit: It is important to know that the leanback library supports all API levels starting from 17. However, you won't have all transitions and the BackgroundManager will not work prior to API 21.
