Unity 录屏截屏到Android相册，支持鸿蒙

Unity端截屏代码

  string date = System.DateTime.Now.ToString("dd-MM-yy");
  string fileName="XXXXX";
  string screenshotFilename = fileName + "_"+ date + ".png";
    if (Application.platform == RuntimePlatform.Android)
        {
	        if (UnityCallAndroidByJavaManager.Intance.isHarmonyOs())
	        {
		        string androidPath = "/mnt/sdcard/DCIM/" + albumName + "/" + screenshotFilename;
		        string path = Application.persistentDataPath + androidPath;
		        string pathonly = Path.GetDirectoryName(path);

		        if (!Directory.Exists(pathonly))
		        {
			        Directory.CreateDirectory(pathonly);
		        }
		        ScreenCapture.CaptureScreenshot(androidPath);

		        yield return new WaitForSeconds(.5f);
	        
		        UnityCallAndroidByJavaManager.Intance.SaveImageOnlyHarmonyOs(path);
	        }
	        else
	        {
		       string androidPath = "/../../../../DCIM/" + albumName + "/" + screenshotFilename;
            
		        string path = Application.persistentDataPath + androidPath;
            
		        string pathonly = Path.GetDirectoryName(path);

		        if (!Directory.Exists(pathonly))
		        {
			        Directory.CreateDirectory(pathonly);
		        }
		        ScreenCapture.CaptureScreenshot(androidPath);
		        AndroidJavaClass obj = new AndroidJavaClass("com.ryanwebb.androidscreenshot.MainActivity");

		        while (!photoSaved)
		        {
			        photoSaved = obj.CallStatic<bool>("scanMedia", path);
			        yield return new WaitForSeconds(.5f);
		        }
	        }

Unity需要的Android Jar及Java代码（由于之前是找的一个Jar库因不支持鸿蒙所以自己动手二次开发的Java调用库）

Unity JAR库（支持Android系统）

需要的Unity调用的Java库的下载链接

下面是部分Java库的代码展示
