title: Leanback library support for API level 19 Android for TV app?
body: <p>Is there a Leanback library support for API level 19 of Android? In this link <a href="https://developer.android.com/reference/android/support/v17/leanback/package-summary.html" rel="nofollow noreferrer">https://developer.android.com/reference/android/support/v17/leanback/package-summary.html</a> Google says it supports API level 21+. So I am not sure if there's a support for API level 19. </p>
