Changing status bar background color prior to Lollipop?

Issue

In Lollipop we can set status bar color using method : http://developer.android.com/reference/android/view/Window.html#setStatusBarColor(int)

What should we use for Android versions prior to Lollipop ?

Solution

There is not much to say. You just can't.

Apps prior to Lollipop had no authority/permission to change status bar color.
