Is there any way to add my custom POIs on maps? - here-api

Question

I have a lot of POIs in my database including location property. How can I add those POIs based on my location on my Map? I found HERE SDK has api like 'Explore Popular Places by Category', but these categories are predefined by HERE. I don't think I can add my POIs to HERE and search by these APIs.
I knew a solution that by adding cluster Marker on Map. but It's difficult and expensive if I retrieve POIs in my database every time. like finding all the POIs which within a circle region(radius is 10 miles). Do you have any better solution for adding custom POIs on HERE map?
Thanks

You may be looking for the Custom Location Extension.

You can add your custom POIs(markers) with custom images using HERE maps, here is the code:
After initialisation map onButtonClick,
SearchRequest searchRequest = new SearchRequest("Water");
searchRequest.execute(discoveryResultPageListener);
then add this method:
private ResultListener<DiscoveryResultPage> discoveryResultPageListener = new ResultListener<DiscoveryResultPage>() {
#Override
public void onCompleted(DiscoveryResultPage discoveryResultPage, ErrorCode errorCode) {
if (errorCode == ErrorCode.NONE) {
List<DiscoveryResult> s_ResultList = discoveryResultPage.getItems();
for (DiscoveryResult item : s_ResultList) {
/*
* Add a marker for each result of PlaceLink type.For best usability, map can be
* also adjusted to display all markers.This can be done by merging the bounding
* box of each result and then zoom the map to the merged one.
*/
if (item.getResultType() == DiscoveryResult.ResultType.PLACE) {
PlaceLink placeLink = (PlaceLink) item;
addMarkerAtPlace(placeLink);
Log.e("nameeee ",""+placeLink.getTitle());
}
}
} else {
Toast.makeText(m_activity,
"ERROR:Discovery search request returned return error code+ " + errorCode,
Toast.LENGTH_SHORT).show();
}
}
};
after this add a method for custom marker,
private void addMarkerAtPlace(PlaceLink placeLink) {
Image img = new Image();
try {
img.setImageResource(R.drawable.camping);
} catch (Exception e) {
e.printStackTrace();
}
MapMarker mapMarker = new MapMarker();
mapMarker.setIcon(img);
mapMarker.setTitle(placeLink.getTitle());
mapMarker.setCoordinate(new GeoCoordinate(placeLink.getPosition()));
m_map.addMapObject(mapMarker);
m_map.setCenter(new GeoCoordinate(placeLink.getPosition()), Map.Animation.NONE);
m_map.setZoomLevel(13);
List<MapObject> m_mapObjectList = new ArrayList<>();
m_mapObjectList.add(mapMarker);
}
