Hi @SogoGolf , Thanks a lot for the request and can I confirm that you are referring to Android API 21? Will pass this onto our product team

[SogoGolf]

Yes that's correct, many thanks

@SogoGolf can you please point your dependency to main branch and confirm support for Android 21?

[SogoGolf]

sorry for the delay. at moment we've got this in pubspec.yaml for Ably:

ably_flutter_plugin: ^1.0.0+dev.2

did you need us to test this against a different version ?

[tiholic]

@SogoGolf yes,

You can try using below configuration in your pubspec.yaml

dependencies:
  ably_flutter_plugin:
    git: https://github.com/ably/ably-flutter

Ref: https://dart.dev/tools/pub/dependencies#git-packages

I gave that a try ;

• changed pubspec.yaml per above
• set min SDK to 21 in app/build.gradle
• flutter clean
• flutter pub get

No issues thus far.

Launched the app in debug mode and saw this error:

1: Task failed with an exception.
