Crash on Android plugin when using IMA sdk on Unity

[Andres Puente Rodriguez]

I'm currently integrating the IMA sdk on a wrapper that is used later by Unity. Unluckily after all initialization of the IMA sdk i'm getting following crash.

Code (Boo):

The crash is happening here.

Code (Java):

new Handler(context.getMainLooper()).post(new Runnable() {

   @override public void run() {

      Log.i("mycrash_onUI_thread", "Time to crash!");

      mAdsLoader = mSdkFactory.createAdsLoader(context, imaSdkSettings, adDisplayContainer);

      mAdsLoader.addAdErrorListener(instance);

      mAdsLoader.addAdsLoadedListener(instance);

   }

});

I already solve this problem once. Before i got this error (NoClassDefFoundError) with a different class when doing the first steps of initialization with the IMA sdk, i solved it by adding the IMA sdk .jar file on Plugins/Android on Unity project.

But, i believe this crash error is from internal android classes, that method createAdsLoader() is calling, so i'm not sure how can i solve it.

I've already tried:

• Upgrading sdk & ndk android versions from 18 all the way to 32
  
• Using unity versions 2020, 2021 & 2022 with latest android sdk versions.
• Looking on maven repos for the (com/google/android/gms/tasks/TaskCompletionSource) .jar file or similars (com/google/android/gms) and adding them to the Plugins/Android/libs folder after making the .arr plugin.
• The .jar files that i've tried are all coming from different internet post trying to solve similar errors (none of them for the "NoClassDefFoundError: ... TaskCompletionSource"), this .jar files are:
  
  • Firebase-messaging
  • multidex
  • google-play-services

Can you confirm that createAdsLoader() method is using something related to the android class "TaskCompletionSource"?.

If thats the case, is there any workaround i could perform?

Kind regards,

Andres

Hi Andres,

Thank you for reaching out to us. 

Please do note that IMA SDK don't have a direct support for Unity plugin, so kindly expect that there could be an error implementing this to a unity platform. In order for us to check this further, could you kindly provide at least a test project via Replay privately to author option?
