Android app crashes every time when launching in release mode

[matthewfx]

I have added new relic 1.0.6

When run in debug it works fine but when an aab or apk in release mode is made it crashes the app every single time when you launch it (on the splash screen).

I have Crashlytics too and that's what I see in logs there

I have checked if I haven't missed anything from the setup but doesn't look like I have

@matthewfx which device are you using? can you share sample app where we can reproduce the issue? we have 500+ apps already in production with this agent.

[matthewfx]

It happens on all devices and emulators. Our app is a pretty mature and big project so I'm guessing maybe there is a clash with some other dependencies. Its size makes it hard for me to build a sample app atm. Do you have any clues what theoretically might be causing NullAgentImpl.getDeviceInformation?

[ndesai-newrelic]

@matthewfx how are you starting your agent? can you share that?

[matthewfx]

Sure:
I'm calling this

Future<void> _newRelicSetup(String appToken) async {
  final Config config = Config(accessToken: appToken);
  FlutterError.onError = NewrelicMobile.onError;
  await NewrelicMobile.instance.startAgent(config);
  NewrelicMobile.instance.recordCustomEvent('AppStarted');
}

among other things I call within runZonedGuarded closure.

@matthewfx can you enable verbose logging and send agent logs ? please check do you call shutdown method anywhere in the code?

[matthewfx]

Hi, I'm sorry but I went for a short holiday and only returned today. I will try to send it later this week.

@matthewfx any update on this one? can i close the issue?
