Hi @upachecog, the main issue reported here (app crash when turning off WiFi) has been resolved in 1.6.8!

There is also some discussion of adding retry logic in this thread. I’m not sure adding that is the best solution though. Most retries will likely fail, which will just drain battery and consume data. Instead, I would suggest listening for the networkStatus event. When you observe a networkStatus event with active equal to false, display a retry button on the UI of your app. Then, when retry is pressed, call Amplify.DataStore.start(). If successful, you will receive another networkStatus event with active equal to true. If not, you will receive a networkStatus event with active equal to false. In 1.6.9, we’ve fixed an issue where the networkStatus event was not firing when the subscription socket is closed. Now, it will be fired any time DataStore is stopped due to a failure.

So, please try out 1.6.9, and let us know if you have any further issues!

I found this issue in Samsung Galaxy A8, Samsung Galaxy A30, and Samsung Galaxy S20

I am using the latest version of Amplify Datastore 1.4.2

It happens just after turning the WiFi off and it is causing the app to crash.

@msiewert I have some discussion to contribute to that! Please, though, let’s create a new issue for it, since it is not related to #731. I’ll chime in on the new one.

@woutermilants it isn’t a typical exponential back-off with jitter retry strategy. So that may be why you don’t recognize it. Look for onlineState.startDetecting(). The online state is observed. When it changes, the sync process is restarted. In other words, the retry happens at the application level, not on individual network calls.

That kind of error typically indicates a network connection failure on the device or emulator. First thing to verify is whether the device or emulator is able to successfully connect to the internet.
