The Material theme lets you easily customize the status bar, so you can specify a
+color which fits your brand and provides enough contrast to show the white status icons. To
+set a custom color for the status bar, use the android:statusBarColor attribute when
+you extend the Material theme.
To handle the color of the status bar yourself (for example, by adding a gradient in the
+background), set the android:statusBarColor attribute to
+@android:color/transparent. You can also use the
+Window.setStatusBarColor method for animations or fading.
