Find Documents By Location with paging

0 votes
I think would be a very useful api call to have. i current have an app with a list of geo referenced images and sort them by location with many images at a single location, I don't want them all at once as it makes the loading of the app really slow as they are all downloaded at once, i would like to show say five and then make a call for the next 5 etc

Hi Aaron,
 
 
 
Please find below code snippet for the same and let me know if you required any other help from our side:
 
String dbName = "<Your_DataBase_Name>";
String collectionName = "<Your_Collection_Name>"; 
GeoTag gp = new GeoTag();
gp.SetLat(-73.99171);
gp.SetLng(40.738868);
GeoQuery query = QueryBuilder.BuildGeoQuery(gp, GeoOperator.NEAR, new BigDecimal(100));
App42Log.SetDebug(true); //Print output in your editor console
App42API.Initialize("API_KEY","SECRET_KEY");
StorageService storageService = App42API.BuildStorageService(); 
storageService.SetPageOffset(0);  // Based on page index, change the value offset value 
storageService.SetPageMaxRecords(10); 
storageService.SetGeoTag(gp);
storageService.FindDocumentsByLocation(dbName, collectionName, query, new UnityCallBack()); 
public class UnityCallBack : App42CallBack
{
public void OnSuccess(object response)
{
Storage storage = (Storage) response;
IList<Storage.JSONDocument> jsonDocList = storage.GetJsonDocList(); 
for(int i=0;i <jsonDocList.Count;i++)
{   
App42Log.Console("objectId is " + jsonDocList[i].GetDocId());
App42Log.Console("jsonDoc is " + jsonDocList[i].GetJsonDoc());
}  
}
 
public void OnException(Exception e)
{
App42Log.Console("Exception : " + e);
}
}
