IEnumerator CRSaveScreenshot()
{
yield return new WaitForEndOfFrame();
// string TwoStepScreenshotPath = MobileNativeShare.SaveScreenshot(“Screenshot” + System.DateTime.Now.Hour + System.DateTime.Now.Minute + System.DateTime.Now.Second);
// Debug.Log("A new screenshot was saved at " + TwoStepScreenshotPath);

     string myFileName = "Screenshot" + System.DateTime.Now.Hour + System.DateTime.Now.Minute + System.DateTime.Now.Second + ".png";
     string myDefaultLocation = Application.persistentDataPath + "/" + myFileName;
     string myFolderLocation = "/storage/emulated/0/DCIM/Camera/JCB/";  //EXAMPLE OF DIRECTLY ACCESSING A CUSTOM FOLDER OF THE GALLERY
     string myScreenshotLocation = myFolderLocation + myFileName;

     //ENSURE THAT FOLDER LOCATION EXISTS
     if (!System.IO.Directory.Exists(myFolderLocation))
     {
         System.IO.Directory.CreateDirectory(myFolderLocation);
     }

     ScreenCapture.CaptureScreenshot(myFileName);
     //MOVE THE SCREENSHOT WHERE WE WANT IT TO BE STORED

     yield return new WaitForSeconds(1);

     System.IO.File.Move(myDefaultLocation, myScreenshotLocation);

     //REFRESHING THE ANDROID PHONE PHOTO GALLERY IS BEGUN
     AndroidJavaClass classPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
     AndroidJavaObject objActivity = classPlayer.GetStatic<AndroidJavaObject>("currentActivity");
     AndroidJavaClass classUri = new AndroidJavaClass("android.net.Uri");
     AndroidJavaObject objIntent = new AndroidJavaObject("android.content.Intent", new object[2] { "android.intent.action.MEDIA_MOUNTED", classUri.CallStatic<AndroidJavaObject>("parse", "file://" + myScreenshotLocation) });
     objActivity.Call("sendBroadcast", objIntent);

The documentation of Unity includes a page describing plugins. Under the Android section, there is a description of how to make a jar file and use AndroidJavaObject to access it in Unity.
RE: How to make and save an Android Screenshot
First, according to this this post , androids have problems encoding to PNG. This postprovided a link to an alternative jpg encoding.
Second, to view the screenshot from the android file manager, the file path needs to be set using Application.persistentDataPath . More in this post.
RE: Android Gallery
After taking a screenshot, the image does not show up in the gallery regardless of the filepath. However, on rebooting the phone, it does a media scan and automatically adds all image files to the gallery, again regardless of the filepath. This post about forcing a media scan, but I have yet to try out the answer
