MyAdapter cannot be cast to com.google.android.gms.ads.NativeExpressAdView

[Pankaj Lilan]

I've been working inRecyclerView and Google Volley for parsing JSON Then I added google native ads!

I following tutorial on this link

So I did change the RecyclerViewAdapter like google developers guideline!

It says that the List has to be a List of Object (List<Object>) So I changed this and a few other things in the Adapter!

Then Android Studio shows no Errors and I'm able to launch the Application. But when I'm going to open the Fragment with the mentioned RecyclerView it crashes.

It says:

java.lang.ClassCastException: com.graciaapps.nameoncards.instance.greetoptions.SubOptionOneInstance cannot be cast to com.google.android.gms.ads.NativeExpressAdView

This is the following line i onBindViewHolder




NativeExpressAdView adView = (NativeExpressAdView)greetingInstanceList.get(position);

 

Thanks in advance!

Hi Pankaj, 

Thank you for reaching out for support. So it looks like this isn't working because you're trying to cast one of your list items that's not supposed to to be an ad to a NativeExpressAdView. You'll want to take a look at our Native Express Recycler Example to see the correct way to set up your app. Specifically, I suggest looking at our onBindViewHolder call. As well as the method we use to add the Native Express Ads to the recycler view. You need to make sure all your classes and activities are consistent with how many items there should be between each ad.

Let me know if you have any further questions.

Hi Chirs,

Thank you for replying, I've re-checked my code of onBindViewHolder() and addNativeExpressAds(), and also referred the example of Native Express Recycler Example. But Still, I didn't understand why the following error is occurring.

03-24 11:36:47.431 19960-19960/com.graciaapps.nameoncards E/MainActivity: The previous Native Express ad failed to load. Attempting to load the next Native Express ad in the items list.

Hi Pankaj,

This is not actually an SDK issue. Something in your implementation is causing your RecyclerView to try and load a Native Express Ad where there isn't one. You need to make sure you're consistent with how many items are expected between each ad. If you're able to send a zip file with a build-able version of your app, I can help you to debug further. Though I'd like to reiterate that this crash is not coming from our SDK and this topic may be better suit for StackOverflow.

java.lang.ClassCastException: Expected item at index 8 to be a Native Express ad????????????????????????

[Chris Feldman (Mobile Ads SDK Team)]

Hi Saeed,

Are you seeing the same error as Pankaj? If so, my response remains the same. You need to make sure you're consistent with how many items are expected between each ad. If you're able to send a zip file with a build-able version of your app, I can help you to debug further, but this is not an SDK issue.

Hi Saeed,

Your issue stems from the fact that you're adding "posts" to your recyclerView asynchronously. Making your API calls this way is causing addNativeExpressAds(), and setUpAndLoadNativeExpressAds()to be called before getPosts()has finished. Because of this, when addNativeExpressAds() is called, mRecyclerViewItems.size() is still zero and your for loop doesn't add any NativeExpressAdViews to your recyclerView. Then setUpAndLoadNativeExpressAds() tries to load ads in an adView that doesn't exist and you're hit with the ClassCastException.

Let me know if you have any further questions. We also saw that you posted again on this thread. For any follow-ups, we ask that you respond only here.

Hi Chris,

I am having the same issue as i am also using Google Volley and Recyclerview for asynchronous loading of items. Can You Help me what should I do Now?. 

Thanks In Advance

Hi Jitander,

This error simply means that the Adapter is expecting a View that is not yet loaded/ available. Purely it is an implementation issue and as my colleague Chris in the previous responses here has suggested, make sure you are calling the ad requests on the proper index of the array. If you are changing the items in the list dynamically, then an ad received might make it to the wrong index, which might not contain the original ad view that the request was made for.

Also, I could see that you have posted this question in several threads. I would like you to continue the discussion in this thread from now on if you still continue to have issues.

Hi Jitander,

Thanks for sharing the project. After looking into your project I could see that you are adding NativeAdView(s) without waiting for your JSON response and the mRecyclerViewItems array is messed up. You are adding the AdView for every 4th iteration, but the array is never ready to handle those. I would suggest that you wait for the JSON to be added into your array, then iterate over every ITEMS_PER_AD, add your AdView, set the adapter and then make the AdRequest. Let me know if that helps.

Hi Deepika,

Its Working Now. All is do is call methods inside onResponse() method which were loading ads in NativeExpressAdviews.. 

Thank You Alot for support.

Hello Guys, 

I am also facing save error, I just want to implement 3 view types in my activity. 1. MENU_ITEM, 2. NATIVE_EXPRESS_ADS every 8th position & 3. LOAD_MORE_VIEW for every 10th position.

But its giving me following error:

Hii,

Make sure to load complete recyclerview items before loading any Native ads.

Hi Jitander,

Thanks for chiming in and that was a good suggestion.

Hey Pankaj,

This is an issue with how you're injecting views into the RecyclerView. It is not an SDK issue. Given the complexity of your implementation, I would suggest posting this on StackOverflow. Your app is crashing because you're trying to load an ad in your 'com.ex.lp.rv.root.SecondPage.Data.TVShow' view. Make sure that you try to implement that in the adview. 

If you have any other issues with our SDK, do let us know and we will be happy to assist you.

Hi Mayank, 

In your onBindViewHolder() function, you have a SWITCH control flow, where you have case MENU_ITEM_VIEW_TYPE, AD_VIEW_TYPE and then default. The AdView has been bind to the AD_VIEW_TYPE case but you are inflating the View and making an AdRequest via the default case. This is not the correct way. Move the holder inflation code into the AD_VIEW_TYPE case in the control flow and it will work.

Let us know if you need anything else.
