I'm working on an Android app that uses the Google Map. I have large Polygon that hides the map. But the labels are above of this but I want them under my Polygon. I do not want to turn off labels.

how the labels look above the polygon

I can set the labels' color to black to "hide" them but this changes the labels that is not under the Polygon

the map with black labels

this is how I add the polygon to the map:

hidePolygon = myMap.addPolygon(new PolygonOptions()
        .addAll(points)
        .strokeColor(Color.rgb(218, 112, 214))

                .zIndex(100f)
        .fillColor(0xFF000000));

my gmap style json:

    "featureType": "all",
