The WMTS service fails to load via the Android SDK 100.15.6

Question

I have a WMTS service in the WGS84 coordinate system. Here is my code:java 运行   WmtsLayer wmtsLayer = new WmtsLayer("http://36.110.12.228:8866/maptiles/tile/service/wmts/1847007008240704/0/0/6666666666666?request=GetCapabilities", "1847007008240704", TileInfo.ImageFormat.PNG);

wmtsLayer.addLoadStatusChangedListener(new LoadStatusChangedListener() {
@Override
public void loadStatusChanged(LoadStatusChangedEvent loadStatusChangedEvent) {
if(loadStatusChangedEvent.getNewLoadStatus() == LoadStatus.LOADED){
            mapView.getMap().getBasemap().getBaseLayers().add(wmtsLayer);
}
}
});
wmtsLayer.loadAsync();

The code reaches LoadStatus.LOADED, which means the layer loaded successfully, but it is not displayed on the map. What could be the reason? My SDK version is 100.15.6.

Here's also a sample service that should work with GetCapabilities appended:

http://sampleserver6.arcgisonline.com/arcgis/rest/services/WorldTimeZones/MapServer/WMTS?request=GetCapabilities

Can you try it with layer id "WorldTimeZones" and your existing code and see how it behaves?

Alternatively, can you provide us an instance of your service that resolves in the browser? Several efforts to load the URL you provided simply timed out.

Hi @LiChunfeng, it's actually best to pass the clean base service endpoint because the SDK will issue its own GetCapabilities request.

Can you try the following URL in your constructor and let us know if this works?

WmtsLayer WmtsLayer(
    "http://36.110.12.228:8866/maptiles/tile/service/wmts",
    "1847007008240704",
    TileInfo.ImageFormat.PNG
);
