When ı play my game on computer there is no problem.But when ı build my game to phone several functions in the game stops working. One of these functions is go to the next level. Actually ı use common simple code line for this :
public void next()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
}
I have already add my all scenes to build screen.As ı said before ,on computer I can go to next level succesfully.
