Question

I integrated facebook native ads in my android app referring the official docs: https://developers.facebook.com/docs/audience-network/android/native-api.

I have 2 questions:

1) Implementation Advice:

This is how I implemented it.

My RecyclerView is attached to a cursor as data source.
Each row of cursor has a 'type' column.
Based on the 'type' parameter view of each row item is decided in getItemViewType(position) method of the RecyclerView.
I cache facebook native ads in a Hashmap with the key set to nativeAd.getId().
Caching is done using Facebooks NativeAdsManager.
When my rows 'type' is 'ads' then I search the Hashmap for that ads id. Retrieve that ad from Hashmap and display ad view accordingly.

The above implementation works smoothly(most of the time). My question is, how efficient is this implementation? (Do suggest me your ways if you have implemented fb native ads with cursor as data source)

2) Facebook Ads Crash

To display a native ad I use MediaView as suggested by Facebook in the documentation (https://developers.facebook.com/docs/audience-network/android/native-api) to show the ads cover picture.

It works normally while displaying photos but have a unpredictable behavior while displaying video ads. Some video ads crash the app with the following exception:

        at dalvik.system.NativeStart.main(Native Method)

Have no clue on this one, any help would be appreciated. Thanks.
