PlatformException/ClassCastException: java.lang.Integer cannot be cast to java.lang.Long

[timobaehr]

Describe the bug
If I run the app on Android 6 devices, the app crashes. On Android 13 everything works fine. Maybe same bug like #1794?

Affected versions
Looks like this error came up in v10.0.0 and later. 9.x version works.
I tested:

• 10.0.0 - Crash
• 12.0.3+1 - Crash

Stacktrace from debug version

To Reproduce

1. Try to run the app
2. See crash, freezes on splashscreen

I folowed the latest README for Android 6 and 7, but app still crashes at app start.

[MaikuB]

Haven't seen this before, which version of the plugin is this stack trace from? Do you register a function against the onDidReceiveBackgroundNotificationResponse callback?

[timobaehr]

On emulator with Android 7 I cannot reproduce the issue. Is happening on real device with Android 6 (Sony Xperia Compact Tablet, Sony Xperia Compact). I own these devices and can retest.

onDidReceiveBackgroundNotificationResponse

Yes, is defined. This is the implemenation of the funktion:

Future<void> onReceivedNotification(NotificationResponse response) async {
  selectedNotificationPayload = response.payload;
  selectNotificationSubject.add(response.payload);
}

[MaikuB]

What does your initialize call look like?

[MaikuB]

I've opened a PR that I believe would fix the issue. Are you able to help test to confirm if this fixes on the device but having your app point to that branch on the repository? This page provides some examples on how to do this https://dart.dev/tools/pub/dependencies#git-packages

[timobaehr]

Retested on Sony Xperia Z3 Compact (D5803). The issue is solved by this pull request. I move the new libraries on beta test now for real users.

I want to thank you so much. Your response time and the fix was immediately fast! I find that absolutely not self-evident. Thank you for your great work.

For others that are affected:

  flutter_local_notifications:
    git:
      url: https://github.com/MaikuB/flutter_local_notifications.git
      path: flutter_local_notifications
      ref: fix-callback-handle-parsing

[MaikuB]

FYI I'm merging the PR in to release the fix and will delete the branch so I suggest you don't point to that branch for your release as otherwise the build will fail. If you're going to use a Git dependency then fork and maintain your own branch. New release will be published in the next few minutes

[MaikuB]

FYI 12.0.4 has now been published
