Hi,

Try loading the WmsLayer before calling getSublayers(), for example:

WmsLayer wmsLayer = new WmsLayer(url, layerNames);
assertEquals(0, wmsLayer.getSublayers().size());
wmsLayer.loadAsync();

mWmsLayer.addDoneLoadingListener(() -> {
  if (wmsLayer.getLoadStatus() == LoadStatus.LOADED) {
    assertTrue(wmsLayer.getSublayers().size() > 0);

  }
});
