How to fix failing WebView calls

Thank you for your speedy answers. much appreciated!

i found another device with the same problem, except this one had an updated WebView: 150.7871.124 like the other devices that worked.

I updated chrome, but still have the same problem.

i attached the debug log from the second before the problem is started, if that helps debug.txt

Hello @Moshe Raab, PhD ,

Thanks for your question.

The app closing unexpectedly to the background may be caused by a graphics rendering conflict with the older kernel version or a bug in the outdated Android System WebView app.

You can refer to try to following approaches:

First, please try to have the device user open the Google Play Store and update the Android System WebView application to the newest version.

If updating the device is not an option, you can modify your MAUI app to use software rendering for the WebView. You can add the following code to your MauiProgram.cs file to customize the Android handler:

#if ANDROID
Microsoft.Maui.Handlers.WebViewHandler.Mapper.AppendToMapping("DisableHardwareAcceleration", (handler, view) =>
{
    handler.PlatformView.SetLayerType(Android.Views.LayerType.Software, null);
});
#endif

Please note that using software rendering instead of hardware acceleration may result in lower WebView performance. I recommend applying this workaround conditionally (for example, only for specific device models or configurations experiencing the crash) so that it does not degrade the experience for all users on newer devices.

For more information on how to customize native controls using handlers, you can review Customize controls with handlers.

Please try and let me know if it works. I'd be happy to investigate further if needed.

I hope this addresses your question. If this response was helpful, please consider following the guidance to provide feedback. Thank you.
