[Solved] XML file not accessible after building?

Unity Engine
1

This is the second time I’ve run into this issue now but the first time I had a simple workaround. This time I do not. I have a leveldata.xml file in my assets directory. I don’t write to it ever, but it contains the basic level information (name of the level, ID, the series it belongs to) and I read from it one time when the player starts. It works fine in the editor, but when I build to either PC or Android it suddenly can’t see the xml file. I’m starting to wonder if Unity doesn’t include the file in the build despite it being in the Assets folder? I don’t want to use persistentDataPath because we manually register our levels in this file and need it for version control. That’s why it’s in Assets (dataPath).

Any thoughts on this? Oh, and here’s my exception from logcat.

I’m not sure what to do. The file is in Assets/Levels/. I’ll paste my deserialize code too I guess. That’ll likely help. Though it works when ran from the editor perfectly.

    public void DeSerialize(ref List<GameManager.Level> levelList) {

        XmlSerializer serializer = new XmlSerializer(typeof(List<GameManager.Level>));
        using (TextReader reader = new StreamReader(Application.dataPath + @"/Levels/leveldata.xml")) {
            levelList = (List<GameManager.Level>)serializer.Deserialize(reader);
        }
    }

Any assets that aren’t directly referenced aren’t included with a build (aside from scripts since there’s no good way to exclude them). I wouldn’t bother with external files since that doesn’t seem to be relevant to your use case here. Instead just use a TextAsset public variable and drag the XML file to the appropriate slot in the inspector, and reference it that way.

Welp. That did it. Thank you sir.

Can you explain how to did it? I have a TextAsset which takes the file from the Resources folder. But it doesn’twork in android.

Just as Eric said, have your gamemanager or relevant object have an exposed field that’s a TextAsset object type. Click and drag the item over and it will be considered referenced just like that. This will include it in the build.
