title: Android detect if there is colour white on image and display toast
body: <p>I have a static image that has a black background and some white colours on. All I just need to know is how to detect white colours on an image and then display a toast message. Or in other words, if there is a colour white on image then display a toast message. I have been researching for a couple of hours but it seems of no luck. Can someone kind here help me please.</p>
