I am wondering if there is a way to know the zoom in the current document in order to navigate through documents but maintaining the zoom.

thanks,

You can use PSPDFKit#getZoomScale to get zoom scale for current page:

 fragment.getZoomScale(fragment.getPage());

Then, after loading new document, you can set required zoom scale with PSPDFFragment#zoomTo() like this:

 PSPDFDocument document = fragment.getDocument();
 fragment.zoomTo((int) document.getPageSize(pageToDisplay).width / 2,
                 (int) document.getPageSize(pageToDisplay).height / 2,
                 pageToDisplay, zoomScale, animationTime);

Where animationTime can be 0 to zoom immediately without animating.
