Hi everyone,

I’m currently trying to implement an immediate in-app update feature in my Unity game using Google Play’s In-App Update API, but I’m facing a problem with converting AppUpdateType to AppUpdateOptions. Here’s the specific error I’m getting:

Error (CS1503): Argument 1: cannot convert from 'Google.Play.AppUpdate.AppUpdateType' to 'Google.Play.AppUpdate.AppUpdateOptions'

Context:

I want to use the immediate update flow (no priority handling is needed). I’m following the documentation provided here, and here’s a simplified version of my code:

Code Example:

using System.Collections;
using UnityEngine;
using Google.Play.AppUpdate;
using Google.Play.Common;

public class InAppUpdateManager : MonoBehaviour
{
    AppUpdateManager appUpdateManager = new AppUpdateManager();

    private void Start()
    {
        StartCoroutine(CheckForUpdate());
    }

    IEnumerator CheckForUpdate()
    {
        PlayAsyncOperation<AppUpdateInfo, AppUpdateErrorCode> appUpdateInfoOperation = appUpdateManager.GetAppUpdateInfo();
        yield return appUpdateInfoOperation;

        if (appUpdateInfoOperation.IsSuccessful)
        {
            var appUpdateInfo = appUpdateInfoOperation.GetResult();
            
            // Create update options for immediate update
            var appUpdateOptions = AppUpdateOptions.ImmediateAppUpdateOptions();

            // Attempt to start the update
            var appUpdateRequest = appUpdateManager.StartUpdate(appUpdateInfo, appUpdateOptions);
            yield return appUpdateRequest;
        }
        else
        {
            Debug.LogError("Error fetching update info: " + appUpdateInfoOperation.Error);
        }
    }
}

Problem:

The issue happens when I try to start the update using appUpdateManager.StartUpdate(appUpdateInfo, appUpdateOptions); — it gives the error I mentioned above (CS1503). I’m using the immediate update type with the AppUpdateOptions.ImmediateAppUpdateOptions() method, as suggested in the documentation.

What I’ve Tried:

  • Ensuring that the namespaces Google.Play.AppUpdate and Google.Play.Common are included.
  • I’ve checked if the AppUpdateManager is properly initialized.

Unity Version:

  • Unity 2022.3.41f1 LTS
  • Play Core plugin version: 2.1.0

Questions:

  1. Why does this error occur when I try to use AppUpdateOptions?
  2. Is there a specific way I need to configure or pass the options for an immediate update?
  3. How can I fix the error and properly initiate the immediate in-app update?
  4. If possible please provide me a updated script or resource .

Thanks in advance for any help or guidance!
