Activity.onCreateThumbnail() method can do the help . But recently Its deprecated. Only Setting up secure flag can help us remove the application view while app moves to background. But the drawback of this flag is, it will replace the view by white back ground. I want to replace with custom image – Jeyahariprakash May 26 '16 at 13:46
