Unity3D: My Admob Setting window isn't showing properly

Question

so i wanted to experiment with google ads using admob. i am following the official guide from google. i downloaded the Unity Package from official github and imported all the stuff. but i am unable to see all the options in admob settings window.

as soon as i press play button those ID field goes blank. i reimported all the files, downgraded the version but i cant get it to work. it keeps giving me error like assertion failed. some UI bugs. and sometime inspector freezes.

please guide me!

Answer 1

Did you open Unity dashboard, create the project, link the id's then use the scripts.

Do so then add these scripts. Watch this video, then if you want, copy these scripts into your project.

SDK

Create a script, call it "sdk" then paste this:

using UnityEngine;
using UnityEngine.Advertisements;

public class sdk : MonoBehaviour, IUnityAdsInitializationListener
{
    [SerializeField] string _androidGameId;
    [SerializeField] string _iOsGameId;
    [SerializeField] bool _testMode = true;
    [SerializeField] bool _enablePerPlacementMode = true;
    private string _gameId;

    void Awake()
    {
        InitializeAds();
    }

    public void InitializeAds()
    {
        _gameId = (Application.platform == RuntimePlatform.IPhonePlayer)
            ? _iOsGameId
            : _androidGameId;
        Advertisement.Initialize(_gameId, _testMode, _enablePerPlacementMode, this);
    }

    public void OnInitializationComplete()
    {
        Debug.Log("Unity Ads initialization complete.");
    }

    public void OnInitializationFailed(UnityAdsInitializationError error, string message)
    {
        Debug.Log($"Unity Ads Initialization Failed: {error.ToString()} - {message}");
    }
}

Interstitial

Create a script call it "interstital" then paste this code:

using UnityEngine;
using UnityEngine.Advertisements;

public class interstitial : MonoBehaviour, IUnityAdsLoadListener, IUnityAdsShowListener
{
    [SerializeField] string _androidAdUnitId = "Interstitial_Android";
    [SerializeField] string _iOsAdUnitId = "Interstitial_iOS";
    string _adUnitId;

    void Awake()
    {
        // Get the Ad Unit ID for the current platform:
        _adUnitId = (Application.platform == RuntimePlatform.IPhonePlayer)
            ? _iOsAdUnitId
            : _androidAdUnitId;
    }

    // Load content to the Ad Unit:
    public void LoadAd()
    {
        // IMPORTANT! Only load content AFTER initialization (in this example, initialization is handled in a different script).
        Debug.Log("Loading Ad: " + _adUnitId);
        Advertisement.Load(_adUnitId, this);
    }

    // Show the loaded content in the Ad Unit: 
    public void ShowAd()
    {
        // Note that if the ad content wasn't previously loaded, this method will fail
        Debug.Log("Showing Ad: " + _adUnitId);
        Advertisement.Show(_adUnitId, this);
    }

    // Implement Load Listener and Show Listener interface methods:  
    public void OnUnityAdsAdLoaded(string adUnitId)
    {
        // Optionally execute code if the Ad Unit successfully loads content.
    }

    public void OnUnityAdsFailedToLoad(string adUnitId, UnityAdsLoadError error, string message)
    {
        Debug.Log($"Error loading Ad Unit: {adUnitId} - {error.ToString()} - {message}");
        // Optionally execite code if the Ad Unit fails to load, such as attempting to try again.
    }

    public void OnUnityAdsShowFailure(string adUnitId, UnityAdsShowError error, string message)
    {
        Debug.Log($"Error showing Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Optionally execite code if the Ad Unit fails to show, such as loading another ad.
    }

    public void OnUnityAdsShowStart(string adUnitId) { }
    public void OnUnityAdsShowClick(string adUnitId) { }
    public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState) { }
}

Rewarded

Create a script, call it "rewarded" then paste this code:

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Advertisements;

public class rewarded : MonoBehaviour, IUnityAdsLoadListener, IUnityAdsShowListener
{
    [SerializeField] Button _showAdButton;
    [SerializeField] string _androidAdUnitId = "Rewarded_Android";
    [SerializeField] string _iOsAdUnitId = "Rewarded_iOS";
    string _adUnitId;

    void Awake()
    {
        // Get the Ad Unit ID for the current platform:
        _adUnitId = (Application.platform == RuntimePlatform.IPhonePlayer)
            ? _iOsAdUnitId
            : _androidAdUnitId;

        //Disable button until ad is ready to show
        _showAdButton.interactable = false;
    }

    // Load content to the Ad Unit:
    public void LoadAd()
    {
        // IMPORTANT! Only load content AFTER initialization (in this example, initialization is handled in a different script).
        Debug.Log("Loading Ad: " + _adUnitId);
        Advertisement.Load(_adUnitId, this);
    }

    // If the ad successfully loads, add a listener to the button and enable it:
    public void OnUnityAdsAdLoaded(string adUnitId)
    {
        Debug.Log("Ad Loaded: " + adUnitId);

        if (adUnitId.Equals(_adUnitId))
        {
            // Configure the button to call the ShowAd() method when clicked:
            _showAdButton.onClick.AddListener(ShowAd);
            // Enable the button for users to click:
            _showAdButton.interactable = true;
        }
    }

    // Implement a method to execute when the user clicks the button.
    public void ShowAd()
    {
        // Disable the button: 
        _showAdButton.interactable = false;
        // Then show the ad:
        Advertisement.Show(_adUnitId, this);
    }

    // Implement the Show Listener's OnUnityAdsShowComplete callback method to determine if the user gets a reward:
    public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState)
    {
        if (adUnitId.Equals(_adUnitId) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
        {
            Debug.Log("Unity Ads Rewarded Ad Completed");
            // Grant a reward.

            // Load another ad:
            Advertisement.Load(_adUnitId, this);
        }
    }

    // Implement Load and Show Listener error callbacks:
    public void OnUnityAdsFailedToLoad(string adUnitId, UnityAdsLoadError error, string message)
    {
        Debug.Log($"Error loading Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Use the error details to determine whether to try to load another ad.
    }

    public void OnUnityAdsShowFailure(string adUnitId, UnityAdsShowError error, string message)
    {
        Debug.Log($"Error showing Ad Unit {adUnitId}: {error.ToString()} - {message}");
        // Use the error details to determine whether to try to load another ad.
    }

    public void OnUnityAdsShowStart(string adUnitId) { }
    public void OnUnityAdsShowClick(string adUnitId) { }

    void OnDestroy()
    {
        // Clean up the button listeners:
        _showAdButton.onClick.RemoveAllListeners();
    }
}

Banner

Create a script call it banner, then paste this code:

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Advertisements;

public class banner : MonoBehaviour
{
    // For the purpose of this example, these buttons are for functionality testing:
    [SerializeField] Button _loadBannerButton;
    [SerializeField] Button _showBannerButton;
    [SerializeField] Button _hideBannerButton;

    [SerializeField] BannerPosition _bannerPosition = BannerPosition.BOTTOM_CENTER;

    [SerializeField] string _androidAdUnitId = "Banner_Android";
    [SerializeField] string _iOsAdUnitId = "Banner_iOS";
    string _adUnitId;

    void Start()
    {
        // Disable the button until an ad is ready to show:
        _showBannerButton.interactable = false;
        _hideBannerButton.interactable = false;

        // Set the banner position:
        Advertisement.Banner.SetPosition(_bannerPosition);

        // Configure the Load Banner button to call the LoadBanner() method when clicked:
        _loadBannerButton.onClick.AddListener(LoadBanner);
        _loadBannerButton.interactable = true;
    }

    // Implement a method to call when the Load Banner button is clicked:
    public void LoadBanner()
    {
        // Set up options to notify the SDK of load events:
        BannerLoadOptions options = new BannerLoadOptions
        {
            loadCallback = OnBannerLoaded,
            errorCallback = OnBannerError
        };

        // Load the Ad Unit with banner content:
        Advertisement.Banner.Load(_adUnitId, options);
    }

    // Implement code to execute when the loadCallback event triggers:
    void OnBannerLoaded()
    {
        Debug.Log("Banner loaded");

        // Configure the Show Banner button to call the ShowBannerAd() method when clicked:
        _showBannerButton.onClick.AddListener(ShowBannerAd);
        // Configure the Hide Banner button to call the HideBannerAd() method when clicked:
        _hideBannerButton.onClick.AddListener(HideBannerAd);

        // Enable both buttons:
        _showBannerButton.interactable = true;
        _hideBannerButton.interactable = true;      
    }

    // Implement code to execute when the load errorCallback event triggers:
    void OnBannerError(string message)
    {
        Debug.Log($"Banner Error: {message}");
        // Optionally execute additional code, such as attempting to load another ad.
    }

    // Implement a method to call when the Show Banner button is clicked:
    void ShowBannerAd()
    {
        // Set up options to notify the SDK of show events:
        BannerOptions options = new BannerOptions
        {
            clickCallback = OnBannerClicked,
            hideCallback = OnBannerHidden,
            showCallback = OnBannerShown
        };

        // Show the loaded Banner Ad Unit:
        Advertisement.Banner.Show(_adUnitId, options);
    }

    // Implement a method to call when the Hide Banner button is clicked:
    void HideBannerAd()
    {
        // Hide the banner:
        Advertisement.Banner.Hide();
    }

    void OnBannerClicked() { }
    void OnBannerShown() { }
    void OnBannerHidden() { }

    void OnDestroy()
    {
        // Clean up the listeners:
        _loadBannerButton.onClick.RemoveAllListeners();
        _showBannerButton.onClick.RemoveAllListeners();
        _hideBannerButton.onClick.RemoveAllListeners();
    }
}

Do watch the video because it does contain some changes to the script and show to use.
