I am adding a long polyline to connect my transit points. The line is fine when the zoom level is default but as soon as I zoom the lines disappear. This behavior is very random as some line disappear when I zoom once and some disappear on full zoom and some on medium zoom. Few questions on SO have a solution to change the z-index but it does not work.Polylines fineDisappear on zoom

  • unless adding the code which produces this behavior ...this only permits guessing. – Martin Zeitler Mar 12 '19 at 00:51

  • How about this one (v2) [Bug:Polyline disappear Google issue 35830044](https://issuetracker.google.com/issues/35830044) ?. Are we supposed to guess what your problem **is** ? You need to provide *test cases*. (*minimum code* to **replicate** your problem). There are **MANY** more.. *unfortunately* `Polyline` is, and *always* has been *riddled* with bugs. – Jon Goodwin Mar 12 '19 at 03:15

After some digging, here's a possible duplicate - Polylines on android map disappear when zoomed out.

Try something like this, as OP suggested.

map.addPolyline(new PolylineOptions()
        .add(new LatLng(85, 5))
        .add(new LatLng(-85, 5))
        .width(2)
        .color(Color.BLUE));
