Network Error Handling

[shivshav]

How should we react when we get an error?

• Retrofit
  • Network
    • Timeout, pi not running, etc.
  • Http (status code != 2xx)
    • Unauthorized, not found, server error, etc.
  • 'ParseError'
    • Unable to parse response from network

What do we do with the subscription? (See Below)

* Cancel it?
* Resume?
* Exponential backoff? Then what?
* Move to "off mode" interval?

When do we alert the user?

After the first failure.

• Alert the user with a Snack bar message
  • Snackbar action will be "Retry"
    • If user interacts, we go to exponential backoff until we hit "off" mode, then go to retry and wait
    • Else, flip FAB to "Refresh/Retry" button and wait

What do we set the bottom toolbar to?

• Mode
  • "Technical Difficulties"
  • "NETWORK UNAVAILABLE"
  • "SOUS VIDE NOT FOUND"
• Dialogbox?
  • Maybe after the retry(see above)
  • "Unable to connect. Please make sure the sous vide is running"
• FAB
  • Make into refresh/retry button(?)
