What is the difference between LinearLayout and LinearLayoutCompat

Question

I know that it LinearLayoutCompatwas implemented to give us several new methods that were added at higher levels of android to lower levels of android.

My problem is this method:

 linearLayout.setPaddingRelative

What was added in API 17, but we must use it in a lower API using the following code:

 linearLayoutCompat.setPaddingRelative

But my Android Studio still shows the following error.

 Call requires API level 17 (current min is 15): android.view.View#setPaddingRelativ

So what is the difference between LinearLayoutand LinearLayoutCompat?
