LogCat Error & Invitation Code Setup in SpeziKt for Android

Spezi

Description

Hi Spezi Team,

I’m currently working with the Spezi Framework, where my goal is to understand its structure and functionality so that our team can explore the possibility of using it to develop an application.

So far, I’ve successfully set up the backend and connected to the Firebase emulator locally. However, I keep encountering an error in the Android Studio LogCat, as shown below. Initially, I though this error might be problamatic, but after setting up Firebase correctly, the app ran anyway. I’d like to understand what this error means and whether it could cause issues later in the development process.

Invitation Code Setup

Additionally, I was wondering if I could get more information on how to set up the Invitation Code page. Specifically:

• Where the invitation code is supposed to be sent;
• If this functionality is partially implemented or if I need to configure it further.

To bypass the Invitation Code requirement and proceed further, I changed the following code by setting hasInvitationCodeConfirmed = true:

private suspend fun getRegisteredUserState(): UserState.Registered = withContext(ioDispatcher) {
     runCatching {
          val document = userDocument().get().await()
          registeredUser(document = document)
     }.getOrDefault(
          UserState.Registered(
               hasInvitationCodeConfirmed = false,
               disabled = false,
          )
     )
}

After making this change, another error was encountered, which appears multiple times in LogCat for different measurements/data (examples shown below):

Questions:

LogCat Error – Could you provide insight into what this error means and whether it might affect development?

Invitation Code Handling – How is the invitation code supposed to work? Are there specific configurations required?

Bypass Effects – Did changing hasInvitationCodeConfirmed affect other parts of the app, leading to the second error? If so, what would be the proper way to handle this?

Reproduction

Initial Setup

1. Clone the SpeziKt repository.
2. Firebase Setup: create a new project on Firebase Console, and replace the google-services.json file.
3. Connect the project to Google Cloud and replace the ServerClientId.
4. Emulate the Firebase by running Firebase CLI.
5. Run the app in Android Studio with LogCat open.

Note: The first LogCat error starts to appear right after the first modification.

Invitation Code - Changes are explained above.

Expected behavior

The app should run without unexpected LogCat errors, like the one in the first image.
