google places api for unity3d

Question

Wish you a Very Happy New Year!!

Has anyone used Google Places API for Unity3D? I am trying to make an augmented reality app using Places API in Unity3D. I followed all the steps mentioned here

I have first fetched the device coordinates and fed those lat-lon to the places api url for a JSON response (creating an API key for Android). Following is my Unity3D C# code,

#define ANDROID
using UnityEngine;
using System.Collections;
using System.Timers;
using SimpleJSON;

public class Places : MonoBehaviour
{
    static int Neversleep;
    LocationInfo currentGPSPosition;
    string gpsString;
    public GUIStyle locStyle;
    int wait;
    float radarRadius;
    string radarType, APIkey, radarSensor;
    string googleRespStr;

    void Start ()
    {
       Screen.sleepTimeout = SleepTimeout.NeverSleep;
       radarRadius = 1000f;
       radarType = "restaurant";
       APIkey = "MyAPIkey";
       radarSensor = "false";
    }

    void RetrieveGPSData()
    {
        currentGPSPosition = Input.location.lastData;
       gpsString = "Lat: " + currentGPSPosition.latitude + "  Lon: " + currentGPSPosition.longitude + "  Alt: " + currentGPSPosition.altitude + 
         "  HorAcc: " + Input.location.lastData.horizontalAccuracy + "  VerAcc: " + Input.location.lastData.verticalAccuracy + "  TS: " + Input.location.lastData.timestamp;
    }

    void OnGUI ()
    {
       GUI.Box (ScaleRect.scaledRect(25,25,700,100), "");
       GUI.Label (ScaleRect.scaledRect(35,25,700,100), gpsString, locStyle);

       GUI.Box (ScaleRect.scaledRect(25,130,700,800), "");
       GUI.Label (ScaleRect.scaledRect(35,135,700,800), "" +googleRespStr, locStyle);

#if PC
       Debug.Log("On PC / Don't have GPS");
#elif !PC
        Input.location.Start(10f,1f);
       int wait = 1000;

        if(Input.location.isEnabledByUser)
        {
            while(Input.location.status == LocationServiceStatus.Initializing && wait>0)
            {
                wait--;
            }
            if (Input.location.status == LocationServiceStatus.Failed)
         {}

            else
         {
          RetrieveGPSData();
          StartCoroutine(Radar());
            }
        }
        else
        {
            GameObject.Find("gps_debug_text").guiText.text = "GPS not available";
        }
#endif   
    }

    IEnumerator Radar ()
    {
       string radarURL = "https://maps.googleapis.com/maps/api/place/radarsearch/json?location=" + currentGPSPosition.latitude + "," + currentGPSPosition.longitude + "&radius=" + radarRadius + "&types=" + radarType + "&sensor=false" + radarSensor + "&key=" + APIkey;
        WWW googleResp = new WWW(radarURL);
        yield return googleResp;
       googleRespStr = googleResp.text;
       print (googleRespStr);       
    }
}

I am getting correct latitude and longitude coordinates but for place, all I get is this,

{
   "debug_info" : [],
   "html_attributions" : [],
   "results" : [],
   "status" : "REQUEST_DENIED"
}

It would be great if someone could help me out with this...

Thanks in advance!

Edit: Download the JSON files from here and extract and put the folder in Assets folder of your Unity3d project. Refer the above code.

got it working. turns out, if you leave the SHA-1 fingerprint field empty, then also google create API key which can be used in the app.
