How to change color of status bar dynamically in android based upon the foreground image?

Question

I want to implement the same feature as we can see in WhatsApp, while seeing a person's profile the color of the status bar changes based upon the color of the image.

It's called Pallete, use the below function, just pass your bitmap image

  private void setUpPalette(Bitmap bitmap) {
   // you passed your Bitmap image;
    Palette.from(bitmap).
            generate(new Palette.PaletteAsyncListener() {
                @Override
                public void onGenerated(Palette palette) {
                    if (palette != null) {

                       //default color is yellow
                       // set the color to toolbar, whatever
                        int extColor = palette.getVibrantColor(ContextCompat.getColor(MainActivity.this, R.color.yellow));
                         if (getWindow() != null) {
                                getWindow().setStatusBarColor(ContextCompat.getColor(this, extColor));
                                }
                    } else {
                         if (getWindow() != null) {
                                    getWindow().setStatusBarColor(ContextCompat.getColor(this, R.color.fail_safe));
                                                    }
                    }
                }
            });
}
