Bug Android problem with Resources.Load

I want to read my level information using json files. Each level has an equal json file , for example level_1.json.
All of these files are located in the /Assets/Resources/Levels folder in unity.
The problem is the Resource.Load works fine in unity editor on pc, but when I build an apk file for android, everything stopped working an the level information can not be loaded.

Here is the code to load the level information

Code (CSharp):

1. var levelFile = $"Levels/level_{LevelNo + 1}";
2. TextAsset  level= Resources.Load<TextAsset>(levelFile);
3. if (level != null)
4. {
5. var currentLevel = JsonUtility.FromJson<Level>(level.text);
6. //the rest of my code
7. }

I read multiple threads with the same problem, but none of them fix my problem.

 

Have you checked the Android Logcat for error messages? I do something similar (loading JSON files) on Android, and can confirm that it does work.

 

Thanks,
I check it and I found that it was because of a line code right before defining the levelFile variable. I commented it, and the problem has solved.
