App crashes when displaying an advertisement on OnePlus 6

We've published an app in the Google Play store which has the possibility to show advertisements from Google DoubleClick for Publishers.

On certain advertisements the app crashes on the OnePlus 6. We do not get a stacktrace in our crash reporting, but do receive error logs in Google Play console as shown below. We are certain that it is being caused by ads, since it only appears on version which has ads. Also, the crash appears during the time the ad is being rendered.

The backtrace in Google Play shows the following log for every crash:

Locally we managed to reproduce this and got the following trace: https://gist.github.com/Sammekl/66fc018f81a04d21717440924a206bdb

Does anyone know how to either fix or capture this crash? it's impacting a really large userbase right now.

Solution

  • I found the problem. It was caused by installing this app on top of the previous app. The previous app used some form of GPU caching in webviews which interferes with the new app.

    The GPU caching was located in the internal storage location of the app:

    data/data/com.sammekl.myapp/app_webview/GPUCache

    I resolved this issue by recursively removing all files in this directory by using the Kotlin File extension function called deleteRecursively() during first time startup of the new app.

    val gpuCache = File("${context.filesDir.parent}/app_webview/GPUCache")
gpuCache.deleteRecursively()
