If i request a snapshot of some panels with elevations

B4X:
Dim root As B4XView = Activity
root.snapshot

From this


Results in this:



Also the fontcolors are not the same.

How can i get a snapshot of the actual looking activity?

B4XView.Snapshot asks the view to draw itself on a canvas.
The shadows are indeed missing. I can only guess that the shadows are not part of the views tree and are added as a special effect in a different way.
There is no other way to capture a view, other than taking a real screenshot which has many restrictions.

Thanks, as I read on other forums it's because Shadows (Elevation In API25+) are hardware accelerated and is rendered outside of the views pipeline and therefore are not available for caching at the view level.

Too bad I wanted to use the transition effect.
