Я использую Плагин Unity Native Gallery , чтобы сделать то же самое.
Это мой код
public class ScreenshotTaker : MonoBehaviour
{
public bool takingScreenshot = false;
public void CaptureScreenshot()
{
StartCoroutine(TakeScreenshotAndSave());
}
private IEnumerator TakeScreenshotAndSave()
{
takingScreenshot = true;
yield return new WaitForEndOfFrame();
Texture2D ss = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
ss.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
ss.Apply();
// Save the screenshot to Gallery/Photos
string name = string.Format("{0}_Capture{1}_{2}.png", Application.productName, "{0}", System.DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss"));
Debug.Log("Permission result: " + NativeGallery.SaveImageToGallery(ss, Application.productName + " Captures", name));
takingScreenshot = false;
}
}
