Post android Lollipop release android has changed the guidelines for displaying notification icons in the Notification bar. The official documentation says "Update or remove assets that involve color. The system ignores all non-alpha channels in action icons and in the main notification icon. You should assume that these icons will be alpha-only. The system draws notification icons in white and action icons in dark gray.” Now what that means in lay man terms is "Convert all parts of the image that you don't want to show to transparent pixels. All colors and non transparent pixels are displayed in white"

Make sure your image file will have in .png format with transparent background
