Just wanted to know, how can we implement this?

When the external camera is detached / removed, i want to preview the last frame and when it is attached back, it should start working as normal. Need some guidance

I would suggest you to use ImageReader & ImageWriter as a proxy between UVCCamera and Surface.

Set ImageReader as UVCCamera set preview display. And then enqueue to ImageWriter in onImageAvailable listener. Then you could always keep the last Image (into Bitmap)
