(Android)Do not use WebView. However, the WebWiew crashes.

[Dol Jobs]

Load AdMob (NativeAd) into RecyclerView.

The ad is a separate ViewHolder.

A lot of scrolling (stress test) crashes.

Calling the destroy method on the NativeAd of the response will produce the same result.

Is using AdLoader.load () to use webview internally?

Sorry about that.

Hi there,

The SDK does use webviews to render ads. Can you check if you can replicate the same behavior on our sample apps so we can rule out any implementation issues? Additionally, can you provide to us a sample project we can use to replicate the issue in case it is not reproducible using our sample apps? Kindly provide to us the appropriate steps in replicating the behavior as well. You may also use the Reply Privately to Author if you are not comfortable sharing your sample project publicly.

Regards,

Hi

Add sample project.

Click 'Auto Scroll' button.

Crash after 3 to 5 minutes on Pixel device. Sometimes ANR reproduces.

Thank you.

Hi,

Thank you for the sample project.

The issue you have highlighted here is not the SDK, but the sample app implementation. The memory pressure is gradually increasing because there is no recycling of the NativeExpressAdViews, so the further you scroll, the more ad views are created, and since these are not lightweight objects, this increases memory use quite substantially.

Thank you for highlighting this, the solution is to recycle a limited number of ad views using the RecyclerViewAdapter for example, and this would result in a finite memory consumption. The sample app being a fairly simplistic example does not do such recycling. 

Regards

Sam

Hi,

Thank you for the answer.

Let me ask you one more thing.

We have already recycled NativeAdView (NativeContentAdView, NativeAppInstallAdView) in RecyclerView.ViewHolder.

Just the same problem occurs.

We update the RecyclerView by calling the AdLoader.load method and adding the received response (NativeAd) to the RecyclerViewAdapter.

Should I also manage the NativeAd instance used in the RecyclerViewAdapter?

Hi,

Yes you should not hold an increasing number of NativeAds in memory, as they are also somewhat memory intensive. For example, they also hold a reference to a webview.  

You cannot recycle NativeAds as such, so I suggest just having a limited size data object (eg Array) to hold a limited number of native ads, and remove the least recently used ad when a new ad needs to be added and the data object has reached its capacity.

Regards

Sam
