I have a game what I made in 480x320 resolution (I have set it in the build settings) in Unity. But I would like to publish my game for every Android device with every resolutio

Here is my script for scaling the ortographic camera in 2D games

public float screenHeight = 1920f;
public float screenWidth = 1080f;
public float targetAspect = 9f / 16f;
public float orthographicSize;
private Camera mainCamera;

// Use this for initialization
void Start () {

    // Initialize variables
    mainCamera = Camera.main;
    orthographicSize = mainCamera.orthographicSize;

    // Calculating ortographic width
    float orthoWidth = orthographicSize / screenHeight * screenWidth;
    // Setting aspect ration
    orthoWidth = orthoWidth / (targetAspect / mainCamera.aspect);
    // Setting Size
    Camera.main.orthographicSize = (orthoWidth / Screen.width * Screen.height);
}
