[Ads] Java exceptions are thrown when calling AdParam.Builder class methods

[MantasKriksciunas]

Hi,

I'm having trouble with some of HuaweiMobileServices.Ads namespace classes. There seems to be an java.lang.NoSuchMethodError exception thrown at runtime when I execute the following code:

RequestOptions _options = HwAds.RequestOptions;

_options = _options.ToBuilder()
                        .SetTagForChildProtection(TagForChild.TAG_FOR_CHILD_PROTECTION_FALSE)  
                        .SetTagForUnderAgeOfPromise(UnderAge.PROMISE_FALSE)
                        .SetNonPersonalizedAd(NonPersonalizedAd.ALLOW_ALL)
                        .Build();

It seems to happen with every Builder class Set* function. I've tried updating libraries with the latest version from master and clearing the project's cache but it didn't help to solve this.

Perhaps I'm missing something? I could only find these old issues (EvilMindDevs/hms-sdk-unity#46, #56) for reference

Here are the logs: logcat.txt

Hello there.
Thank you for the beautiful description!

I will be looking into it and I'll get back to you 👍

Hello there @MantasKriksciunas
I've tried the same code as you've described in my Init() method but I got no errors. I did change the gradle hms ad versions as you've described as well.

This is the code sample that I modified in HMSAdsKitManager.cs file.

   private void Init()
   {
       HwAds.Init();
       isInitialized = true;
       adsKitSettings = HMSAdsKitSettings.Instance.Settings;
       Debug.LogWarning("Start");
       RequestOptions _options = HwAds.RequestOptions;
       _options = _options.ToBuilder()
                               .SetTagForChildProtection(TagForChild.TAG_FOR_CHILD_PROTECTION_FALSE)
                               .SetTagForUnderAgeOfPromise(UnderAge.PROMISE_FALSE)
                               .SetNonPersonalizedAd(NonPersonalizedAd.ALLOW_ALL)
                               .Build();
       Debug.LogWarning("End");

   }

And this is the resulting screenshot of the logs.

Do you have proguard or something active on the Android side that is stripping some codes by any chance?

[MantasKriksciunas]

Sorry, it seems that I referenced the wrong class here. After retesting, like you said, this code passes without issues.

Exceptions are related not to RequestOptions.Builder but AdParam.Builder class instead. Try executing the following code:

private void Init()
{
      HwAds.Init();
      isInitialized = true;
      adsKitSettings = HMSAdsKitSettings.Instance.Settings;
      Debug.LogWarning("Start");
      
      AdParam.Builder _builder = new AdParam.Builder();
      AdParam _ad_param;

       _ad_param = _builder
            .SetTagForChildProtection(TagForChild.TAG_FOR_CHILD_PROTECTION_FALSE)
            .SetTagForUnderAgeOfPromise(UnderAge.PROMISE_FALSE)
            .SetNonPersonalizedAd(NonPersonalizedAd.ALLOW_ALL)
            .Build();

       Debug.LogWarning("End");
}

Also, I don't have any stripping active or proguard files in the project. I've tested this on a fresh project with the only change being the min SDK version, that's set to 21 instead of the default 19.

Hello there @MantasKriksciunas
You are correct. Our wrapper was not sending the correct method signature to the SDK side so it was not able to find the corresponding method. I've fixed this issue in #263. I will be shipping a new version (2.1.1) on Monday afternoon that will fix this issue.

[MantasKriksciunas]

Hello, I'm glad to hear that you've found the problem. Thank you very much!

[sametguzeldev]

This issue should be resolved in the v2.1.1 release.

Hello,
Can you test again? The issue should be resolved.
