Amplify getting started tutorial on Android crashes with SQLiteConstraintException #840

Closed niqo01 closed 3 years ago

niqo01 commented 4 years ago

I am following the Ampligy getting started tutorial for Android https://docs.amplify.aws/start/getting-started/add-api/q/integration/android I am at the "Connect to the Cloud" step 5, and when I run the application, it crashes with:

E/Tutorial: Observation failed.

Hi @niqo01! Can you please include:

  1. Your GraphQL schema
  2. Relevant code snippets
  3. The type (and API level) of the device you were running this on
niqo01 commented 4 years ago

Hi @jamesonwilliams,

I am following the AWS tutorial and attached the source in the first message. The GraphQL schema and code snippet are in the tutorial.zip. Just in case, here is the MainActivity from the zip above:

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            TestAmplifyTheme {
                // A surface container using the 'background' color from the theme
                Surface(color = MaterialTheme.colors.background) {
                    Greeting("Android")
                }
            }
        }
        Amplify.DataStore.observe(Todo::class.java,
            { Log.i("Tutorial", "Observation began.") },
            { Log.i("Tutorial", it.item().toString()) },
            { Log.e("Tutorial", "Observation failed.", it) },
            { Log.i("Tutorial", "Observation complete.") }
        )
    }
}

The schema:

enum Priority {
  LOW
  NORMAL
  HIGH
}

type Todo @model {
  id: ID!
  name: String!
  priority: Priority
  description: String
}

I am using the Android emulator, API 30 / Android 11 (Google Play) x86

jamesonwilliams commented 4 years ago

Thanks @niqo01! Sorry, missed the zip file :-).

rjuliano commented 4 years ago

@niqo01 Are you getting this message consistently? I used your project with the emulator settings you provided but I'm unable to reproduce the error. Are there any other steps you're going through?

LynkKid commented 4 years ago

I am also having the same problem, please help me

Jacke-debug commented 4 years ago

Same problem. Have gone through the complete tutorial three times now and it did work once.

raphkim commented 4 years ago

Thank you for reporting this issue. We will add this issue to our sprint board to prioritize.

Switcher05 commented 4 years ago

Well I was going through the tutorial and encountered this issue. https://docs.amplify.aws/start/getting-started/integrate/q/integration/android#create-a-todo Step 3 worked fine, made changes in step 4 and now it's broken. Tried undo and rerun step 3 and it's still failing. Not a good week to be trying to convince my team to use Amplify lol.

+1 for @Switcher05

TLDR: In the interest of following this tutorial, This error can be ignored, I have continued with the next steps and was able to get the appropriate logs. We can just monitor logcat with the search filter as com.example.todo I/Tutorial:

2020-10-17 19:55:40.183 11939-11981/com.example.todo I/Tutorial: Saved item: Build Android application 2020-10-17 19:56:35.742 11939-11981/com.example.todo I/Tutorial: Saved item: Finish quarterly taxes

This happens when the Datastore is trying to authenticate according to : https://github.com/aws-amplify/amplify-android/issues/802

As we are using a local datastore we can conveniently continue with the next steps :)

IMHO there should be a warning or caveat in the guide as I wasted close to 20min trying to debug this ;)
