 // attach this to your camera



 using UnityEngine;
 using System.Collections;
 
 public class TakeScreenshot : MonoBehaviour
 {   
     private int screenshotCount = 0;
        
     // Check for screenshot key each frame
     void Update()
     {
         // take screenshot on touch
 
          if (Input.touches.Length > 0)
         {       
             string screenshotFilename;
             do
             {
                 screenshotCount++;
                 screenshotFilename = "screenshot" + screenshotCount + ".png";
 
             } while (System.IO.File.Exists(screenshotFilename));
             
           //  audio.Play();
             
             Application.CaptureScreenshot(screenshotFilename);
         }
     }
 }

I can't find the image file resulting from this script. Is it only visible to the application and not in the file system?

I guess the question is, on iOS or Android, how do you find the directory or working directory path name you are currently in.. Presumably that is where the file is saved.

I think the android file manager has limited visibility. Using the code as it's written here, I went through every file I had access to with the file manager and found nothing. When I assigned the filename using Application.persistentDataPath, the application folder popped up in the file manager with the new image file.

it could also be that there are permission limitations in where the UnityPlayer on Android can write to... in that case, things get more complicated and perhaps you really do need to write a Plugin just to have it write to the android gallery path

well, I had the same problem, but the images are actually there in a folder on the SD card (set force SD card permission) - but the phone gallery can't see them until the phone is plugged in to the computer and then turned back to SD card (then it sees them) or you can turn the phone off and back on I think that would work. Mostly it's not working because I take a picture , then I flip over to the gallery to look for it right away and it's not there... But it is there, you have to re-initialize the SD card... I think ;)

well, if you copy/pasted the code above into a javascript file, that's going to cause a few problems.

Hey,

The code seems to be doing something, but there is no photo showing up in the camera roll on iOS, where is this image being saved? is there a way to save it to the default photo director, whatever that happens to be?

Thanks

Simon.
