1 month ago Hi @aezakmi8, is this limited to android 9 or are other versions of android affected as well?
What version of webview_flutter & webview_flutter_android are you using?

Also I've tested on webview_flutter: ^4.7.0, same error
this limited to android 9 or are other versions of android affected as well?
As far as I know, the reason is the error that the android.webkit.PacProcessor class is used, which is only available in Android 12 and above

@drexhacker, does it crash for you every time or occasionally?

No, on Android 9 crash is not happening
Аn error appears in the console and the content of the webpage either loads partially or fails to load completely

1 month ago Hi @aezakmi8, do you see the android.webkit.PacProcessor error every time? I am testing on android emulator running android 9 but I don't see those error messages from logcat. The warnings, I see are related to the OnBackInvokedCallback and some sidecar related messages.

1 month ago error every time?
The error appears every time we navigate to the screen with WebView
I am testing on Physical device HONOR 9 Lite (LLD-L31) and reading logs from logcat

1 month ago Hi @aezakmi8, I tested this on a Nokia 6 running android 9 and while I do see the error, the website content is fully loaded with no issues. I also saw the logs from flutter itself.
Аn error appears in the console and the content of the webpage either loads partially or fails to load completely
Regarding this, does it ever load the site fully for you?
aezakmi8
commented
1 month ago and while I do see the error, the website content is fully loaded
Web Content loads with a delay (5-30 sec) sometimes it does not fully loads
This is critical because in my application this screen is responsible for paying on an external web site for order payment.

Sorry the crush was not made by webview_flutter.

1 month ago Hi @aezakmi8, does the progress only get stuck on the HONOR 9 Lite? You can check emulators or other devices to see if happens with them as well.
Can you add a navigation delegate that will help up knoww at which level/percentage it gets stuck at? You can define the delegate like so
..setNavigationDelegate(
NavigationDelegate(
onProgress: (int progress) {
// Update loading bar.
print("progress: ($progress)");
},
),
)

1 month ago Steps to reproduce
- Create a new Flutter project or use an existing one.
- Add the
webview_flutterpackage to your project'spubspec.yamlfile and runflutter pub get.- Replace the existing
main.dartfile with the sample widget provided above or download the attachedweb_view_issue.zipand extract the contents to your project directory.- Run the project on an Android 9 device or emulator.
- Observe the console/logcat output and the behavior of the web view.
Expected results
- The console/logcat should not display any errors related to the web view.
- The content of the webpage should load completely without any partial loading or failure to load."
Actual results
- The console/logcat displays errors related to the web view.
- The content of the webpage either loads partially or fails to load completely.

I have the same logs, also on a real device with Android 9. It's not crashing, but the logs are the same. Only on the first build of the webview

If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'.
