Describe the bug

When steps described below are followed, only ambigious "Sorry, something went wrong" -message is shown to the user by Amplify-UI i.e. the Application does not get to show any content at all. Furthermore, the only way to recover from this state is to set the device back online and then killing the app and launching it again.

With AndroidLoggingPlugin enabled I can see the following exception in Logcat:
InvalidUserPoolConfigurationException, which seems incorrect.

Reproduction steps (if applicable)

1. Sign-in to the App
2. Set device offline
3. Kill the App
4. Wait for access token to expire
5. Launch the App

Thanks for the report @pmellaaho. It looks like Amplify cannot refresh the tokens because the device is offline, but is returning an incorrect error - we'll have to investigate on the Amplify side for that.

For Authenticator there are two things to look at here:

• Although the access token is expired, the user is still "signed in" so it should be able to go to the signed-in state.
• There should probably be a retry button on the general exception UI so that user could recover if the device comes back online.

I would appreciate if you could share any new regarding this bug as it's quite annoying for the end users. I also think that iOS version does not have this bug?

[mattcreaser]

Hi @pmellaaho. I apologize for not seeing this sooner. I'm going to look into this now and should be able to get back to you later this week.

[mattcreaser]

I've opened a fix for the root cause in the Amplify library here: aws-amplify/amplify-android#2985. That fix should completely resolve this issue.

I'll also look into adding a retry button on the generation exception UI for other any other potentially-recoverable errors that might occur.

[mattcreaser]

This fix has been released, please upgrade to Authenticator 1.4.1. This is the "root cause" fix. The option to retry in similar scenarios is still outstanding in #210.

Please let us know if you encounter any issues.
