Question Java Plugin for Android Advertising Id. Unity 2020

Hi, fellow coders.

Would you please help me understand what am I missing. For the first time Im trying to use Java.

First I found Unity Ads package on github, because it has the class for the very same purpose:
(the only thing I changed is package. Is that correct?)

Code (CSharp):

1.  
2. package com.my.trackingid;
3.  
4. import android.content.ComponentName;
5. import android.content.Context;
6. import android.content.Intent;
7. import android.content.ServiceConnection;
8. import android.os.Binder;
9. import android.os.Build;
10. import android.os.IBinder;
11. import android.os.IInterface;
12. import android.os.Parcel;
13. import android.os.RemoteException;
14.  
15. import com.unity3d.services.core.log.DeviceLog;
16.  
17. import java.util.concurrent.BlockingQueue;
18. import java.util.concurrent.LinkedBlockingQueue;
19.  
20. public class AdvertisingId {
21.  
22.     private static final String ADVERTISING_ID_SERVICE_NAME = "com.google.android.gms.ads.identifier.internal.IAdvertisingIdService";
23.  
24.     private static AdvertisingId instance = null;
25.     private String advertisingIdentifier = null;
26.     private boolean limitedAdvertisingTracking = false;
27.  
28.     private static AdvertisingId getInstance() {
29.         if (instance == null) {
30.             instance = new AdvertisingId();
31.         }
32.         return instance;
33.     }
34.  
35.     public static void init(final Context context) {
36.         getInstance().fetchAdvertisingId(context);
37.     }
38.  
39.     public static String getAdvertisingTrackingId() {
40.         return getInstance().advertisingIdentifier;
41.     }
42.  
43.     public static boolean getLimitedAdTracking() {
44.         return getInstance().limitedAdvertisingTracking;
45.     }
46.  
47.  
48.     private void fetchAdvertisingId(Context context) {

61.                 advertisingIdentifier = advertisingInfo.getId();
62.                 limitedAdvertisingTracking = advertisingInfo.getEnabled(true);
63.             }
64.         } catch (Exception e) {

66.         } finally {

187.             return _binderQueue.take();
188.         }
189.     }

Then, in C# im trying to access this class with that code:

Code (CSharp):

1.  
2. using System.Collections;
3. using UnityEngine;
4.  
5. public class AdsIds : MonoBehaviour
6. {
7.     public static AdsIds adId;
8.  
9. #if UNITY_ANDROID
10.     AndroidJavaObject currentActivity = null;
11.     AndroidJavaObject adInfo = null;
12.  
13. #endif
14.  
15.     private void Awake()
16.     {
17.         adId = this;
18.     }
19.     public void getID()
20.     {
21.         StartCoroutine(getIDcouroutine());
22.     }
23.  
24.     private IEnumerator getIDcouroutine()
25.     {
26. #if UNITY_ANDROID
27.  
28.         if (currentActivity == null)
29.         {
30.             using (AndroidJavaClass up = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
31.             {
32.                 currentActivity = up.GetStatic<AndroidJavaObject>("currentActivity");
33.                 using (AndroidJavaClass client = new AndroidJavaClass("com.my.trackingid"))
34.                 {
35.  
36.                     adInfo = client.CallStatic<AndroidJavaObject>("init", currentActivity);
37.                 }
38.             }
39.         }
40.             DataBasePlayer.dbplayer.ifa = adInfo.CallStatic<string>("getAdvertisingTrackingId").ToString();
41.  
42. #elif UNITY_IOS
43.             Application.RequestAdvertisingIdentifierAsync(
44.             (string advertisingId, bool trackingEnabled, string error) =>
45.             {
46.             DataBasePlayer.dbplayer.ifa = advertisingId;
47.             }
48.             );
49. #else
50.             DataBasePlayer.dbplayer.ifa = "platform not supported";
51. #endif
52.             yield return null;
53.         }
54.     }
55.  
56.  

Then I build, and log the result from device and there is default result - string "none".

 

My condolences. Seriously.

Are there any other exceptions in the log? I mean by looking with

adb logcat

?

Is there any reason you are reaching for a Java nightmare instead of just using this:

https://docs.unity3d.com/ScriptReference/Application.RequestAdvertisingIdentifierAsync.html

?

 

Actually I just broke entire project when tried to replace gradle, so cant look at the logs right now.
Last errors were about missing dependencies, but I didn't find out how to resolve them without pain, so I tried to open the project in Android Studio and it didnt help, just made it worse.

This method is no longer supported in Unity 2020 for Android platform.
