Scene loading only working in Unity

Unity Engine
1

Hi!

I’m working on a mobile game, which has a level selection. I have a GameManager singleton instance in the first(Main menu) scene, I put it in the DoNotDestroyOnLoad. Have a list of scene objects in it, which I set in the editor. On start, I take the list of scenes, and get the names, creating as many buttons for level selections as many scenes I have in the list. And when I click on the button, just read it’s property, which is the scene’s name, and load it. It’s perfectly working in editor, even in unity remote with phone, but when I build the project, install it on my android phone, There is no level button(so it didn’t find the scenes in the list), and when I somehow manage to add one, it won’t load the scene.
Does anyone have any idea, what’s the problem?

GameManager:

void Awake()
    {
        if (_GameManager != null && _GameManager != this)
        {
            Destroy(this);
        } else
        {
            _GameManager = this;
            DontDestroyOnLoad(this);
        }

        List<string> tempList = new List<string>();
        foreach (Object scene in sceneObjects)
        {
            tempList.Add(scene.name);
        }
        levels = tempList.ToArray();
    }

SceneManager:

void Start()
    {
        for (int i = 0; i < GameManager._GameManager.levels.Length; i++)
        {
            GameObject newStage = Instantiate(stageReference, new Vector3(0, 0, 0), Quaternion.identity, parentReference.transform);
            newStage.GetComponent<Level>().SetLevelNumber(i+1);
            newStage.GetComponent<Level>().SetSceneName(GameManager._GameManager.levels[i]);
        }
    }

LevelObject:

public void HandleClickedOnLevel()
    {
        if (unlocked)
        {
            SceneManager.LoadScene(sceneName);
        }
    }

When you build the project do you include the desired scenes into the build settings scene list?

Yes

I would try to make a build for windows (or whatever OS you are developing on) and see if it works there to verify wether its an Android thing or not.
I have never worked with Android so I’m not much help with their specifics.

Since you describe your singleton setup do you suspect the issue to arise from this?

Okay, I’ll try that in a minute.
And yes, maybe after build, my GameManager loose there scene references, I just have no idea how can I debug that. And what’s the fix for that, if it’s that.

Okay, I think I got it. In my singleton, I stored a list of objects, what were the scenes, and in the loop, I got the name of it, which the build didn’t like. I switched so I give strings to the list, and now it seems like working. Thanks for the help!
