Foursquare API venues search returns empty venues

Question

I'm writing an Android app using Foursquare APIs. I'm trying to make a request to this URL:

    String url = "https://api.foursquare.com/v2/venues/search?ll=16.31503,38.973039&"
        +"client_id="+CLIENT_ID+"&client_secret="+CLIENT_SECRET+"&limit=25&v="+date;

where date is formatted in YYYYMMDD. I actually have a response, but the venues array is empty:

{
    meta: {
        code: 200
    }
    notifications: [
       {
         type: "notificationTray"
         item: {
             unreadCount: 0
         }
       }
    ]
    response: {
        venues: [ ]
    }
}

Why is it empty?

Answer 1

这是因为不幸的是，您要搜索的区域并不多。看看在网络上运行相同搜索的结果： https : //foursquare.com/explore?near=16.31503%2C38.973039 （放大一点，看看有什么结果）

Answer 2

I confused longitude with latitude and vice versa. My mistake! Thank you (:
