How can I change the color of the status bar? (Android and IOS)

Question

Sorry for the big picture.

I did some research, including here on the stackoverflow, but I was not successful with the options I found.

Answer 1

In styles.xml add following line in theme

<item name="android:statusBarColor">@color/colorPrimary</item>

Answer 2

** CHANGE THE COLOR OF THE STATUS BAR**

** REMOVE THE STATUS BAR COLOR**

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
