Canvas-Green Screen removal

[Marko Miljkovic]

Hi there guys. I started working in Android development a few weeks ago. And i have some project, where i would need to remove green screen in gif, and play it over video. Is there a way i can do that in Android.canvas, or would it need to be done in Open GL? I found some articles about that, in Open GL, but not in Android.canvas.

Thanks in advance
