How to change the status bar color in Android?

Android 5.0 Lollipop introduced Material Design theme which automatically colors the status bar based on the colorPrimaryDark value of the theme.

This is supported on device pre-lollipop thanks to the library support-v7-appcompat starting from version 21. Blogpost about support appcompat v21 from Chris Banes

Update:

Lollipop:

public abstract void setStatusBarColor (int color)

Added in API level 21

Android Lollipop brought with it the ability to change the color of status bar in your app for a more immersive user experience and in tune with Google’s Material Design Guidelines.

Here is how you can change the color of the status bar using the new window.setStatusBarColor method introduced in API level 21.

Changing the color of status bar also requires setting two additional flags on the Window; you need to add the FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag and clear the FLAG_TRANSLUCENT_STATUS flag.

Working Code:

import android.view.Window;

...

Window window = activity.getWindow();// clear FLAG_TRANSLUCENT_STATUS flag:window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the windowwindow.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);// finally change the colorwindow.setStatusBarColor(ContextCompat.getColor(activity,R.color.my_statusbar_color));

Offcial developer reference : setStatusBarColor(int)
