How can I capture an image using ARCore Camera with objects?

I am creating an application using ARCore to display some images on blank surface. I want to capture image of that surface where object is display. I have put a capture button on AR camera screen.

Is it possible to capture that view with objects in ARCore camera?

Capturing Sceneform scene + BG image

The method below allows you acquire an image from the Sceneform's scene that corresponds to the current frame along with a background image from camera's current AR frame. To capture a content of viewport, use the following approach:

fun makingTheScreenShot(
    leftTopRightBottom: Rect,
    activity: Activity,
    onLuck: (Bitmap) -> Unit
) {
    val bitmap = Bitmap.createBitmap(
        leftTopRightBottom.width(), 
        leftTopRightBottom.height(), 
        Bitmap.Config.ARGB_8888     
        // each pixel is stored on 4 bytes
    )
    PixelCopy.request(
        activity.window, 
        leftTopRightBottom, 
        bitmap,
        { if (it == PixelCopy.SUCCESS) onLuck(bitmap) },
        Handler(Looper.getMainLooper())
        // main thread of the app
    )
}

Then save it to disk (you can try this method):

makingTheScreenShot(
    activity.getViewRect()
    activity, 
) {
    // Use your function to save 
    // a captured image to disk
}

If you simply need a screenshot of the ARCore view you can try using some Android functionality such as PixelCopy.request(view, bitmap, (copyResult)->{}) on the ArSceneView of the ARCore fragment.
