Create a C# Wrapper Class With a Listener Proxy Class

This wrapper bridges Unity and the native Android library.

using System;
using UnityEngine;

public class PlaytimeAds
{
    private AndroidJavaObject objPlaytimeAds;
    private AndroidJavaObject unityActivity;
    public static Action OnInitSuccess;
    public static Action OnInitFailed;
    public PlaytimeAds()
    {
        using (AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
        {
            unityActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
        }
        using (AndroidJavaClass javaClass = new AndroidJavaClass("com.playtimeads.PlaytimeAds"))
        {
            objPlaytimeAds = javaClass.CallStatic<AndroidJavaObject>("getInstance");
        }
    }
    public void DestroyPlaytimeAds()
    {
         if (objPlaytimeAds != null)
         {
             // Call the method in the Java class without expecting a return value
             Debug.LogError("destroyPlaytimeAds method is getting called");
             objPlaytimeAds.Call("destroy");
         }
         else
         {
             Debug.LogError("Failed to create Android class instance destroyPlaytimeAds.");
         }
    }
    public void Init(string applicationId, string userId)
    {
        if (objPlaytimeAds != null)
        {
            var listenerProxy = new Proxy.Listener();
            Debug.Log("init method is getting called" + userId);
            objPlaytimeAds.Call("init",unityActivity, applicationId, userId,listenerProxy);
        }
        else
        {
            Debug.LogError("Failed to create Android class instance. isInitPlaytimeAds1");
        }
    }

    public void OpenOfferWall()
    {
        if (objPlaytimeAds != null)
        {
            // Call the method in the Java class without expecting a return value
            Debug.LogError("open Offerwall method is getting called");
            // objPlaytimeAds.Call("isInitialized");
            objPlaytimeAds.Call("open",unityActivity);
        }
        else
        {
            Debug.LogError("Failed to create Android class instance. isInitPlaytimeAds1");
        }
    }
}
namespace Proxy
{
    public class Listener : AndroidJavaProxy
    {
        public Listener() : base("com.playtimeads.listeners.OfferWallInitListener") { }

        // Implement the onSuccess method
        public void onInitSuccess()
        {
            PlaytimeAds.OnInitSuccess?.Invoke();
            Debug.Log("onInitSuccess is called");
        }

        public void onAlreadyInitializing()
        {
            Debug.Log("onAlreadyInitializing is called");
        }

        // Implement the onFailure method
        public void onInitFailed(string error)
        {
            PlaytimeAds.OnInitFailed?.Invoke();
            Debug.LogError("onInitFailed is called: " + error);
        }
    }
}

Create a Manager Class

This manager centralizes all interactions with the wrapper class.

public class PlaytimeAdsManager : Manager<PlaytimeAdsManager>
{
    private PlaytimeAds _playtimeAds;
    public PlaytimeAds PlaytimeAds => _playtimeAds ??= new PlaytimeAds();

    public void InitializeWithUserId(string userId)
    {
#if !UNITY_ANDROID || UNITY_EDITOR
        Debug.Log("PlaytimeAds Initialization Skipped in Editor");
        return;
#endif
        Debug.Log("Initializing PlaytimeAds...");
        PlaytimeAds.OnInitSuccess += OnInitSuccess;
        PlaytimeAds.OnInitFailed += OnInitFailed;
        PlaytimeAds.Init(userId);
    }

    private void OnInitSuccess()
    {
        Debug.Log("PlaytimeAds Initialized Successfully");
    }

    private void OnInitFailed()
    {
        Debug.Log("PlaytimeAds Initialization Failed");
    }

    public void DestroyPlaytimeAds()
    {
#if !UNITY_ANDROID || UNITY_EDITOR
        Debug.Log("Destroy Skipped in Editor");
        return;
#endif
        PlaytimeAds.DestroyPlaytimeAds();
    }

    public void OpenOfferWall()
    {
#if !UNITY_ANDROID || UNITY_EDITOR
        Debug.Log("Open Offerwall Skipped in Editor");
        return;
#endif
        PlaytimeAds.OpenOfferWall();
    }
}
