Issue - Build & Run fails with "Package version not found" error

[ahmadrazagd]

Whenever I tap on Build & Run in unity. Simple Build button is working fine.
I encounter this error Package version not found

This is because, MeticaEditorUtilities.cs does not create any file if sdkInfo.json is not available inside streaming assets.

We have two solutions here.

1. Create the file (if not available) before accessing it.
2. Skip file checking using if statement

Here is the actual method

internal static void WriteJsonSdkInfo()
{
    string sdkInfoFolder = SdkInfo.SdkInfoFolder;

    if (!Directory.Exists(sdkInfoFolder))
    {
        Directory.CreateDirectory(sdkInfoFolder);
        AssetDatabase.Refresh();
    }

    string filePath = Path.Combine(sdkInfoFolder, "sdkInfo.json");

    string packageVersion = GetPackageVersion("com.metica.unity");
    if (packageVersion != null)
    {
        string jsonData = $"{{\"Version\": \"{packageVersion}\"}}";  // Ensure version is quoted for valid JSON
        File.WriteAllText(filePath, jsonData);
        AssetDatabase.Refresh();
    }
    else
    {
        Debug.LogError("Package version not found.");
    }
}

Here is the fix (I applied the second solution)

internal static void WriteJsonSdkInfo()
{
    string sdkInfoFolder = SdkInfo.SdkInfoFolder;

    if (!Directory.Exists(sdkInfoFolder))
    {
        Directory.CreateDirectory(sdkInfoFolder);
        AssetDatabase.Refresh();
    }

    string filePath = Path.Combine(sdkInfoFolder, "sdkInfo.json");

    if (File.Exists(filePath))
    {
        string packageVersion = GetPackageVersion("com.metica.unity");
        if (packageVersion != null)
        {
            string jsonData =
                $"{{\"Version\": \"{packageVersion}\"}}"; // Ensure version is quoted for valid JSON
            File.WriteAllText(filePath, jsonData);
            AssetDatabase.Refresh();
        }
        else
        {
            Debug.LogError("Package version not found.");
        }
    }
}

@ahmadrazagd Thank you for the report! I suspect a platform specific path issue. On what device are you running the application when you get the error? If you can add more info on your system that'd be great; most importantly, can you check the full path of the file?

Edit: I tried a B&R targeting my Android phone and the app is built, side-loaded and run with no issues. 🤔
