Android lollipop UI in KitKat

Question

I am developing an android app and I would like to have android l ui on it even for KitKat. I have seen apps like inbox and pushbullet to use this such as the rotation of the circle button and the status bar recolor. How do they do this?

Answer 1

Make use of the Android Support Library to maintain backwards compatibility.

According to the documentation:

The v7 Support Libraries r21 and above includes the following material design features:

• Material design styles for some system widgets when you apply one of the Theme.AppCompat themes.
• Color palette theme attributes in the Theme.AppCompat themes.
