I may just be missing something obvious, but I am having an issue with a Unity script that shares a line of text and an image to external apps (e.g. Twitter).

I can send the text perfectly fine, but the image (which is supposed to be an in-game screenshot) will not appear as an attachment to the message.

I’ve tried changing the filepath string to be the filepath of a pre-existing PNG file on my phone, in case the screenshot section of the code doesn’t work, but I’m still having the same issue. I’ve also tried changing the File:// to be all lowercase (which causes the code to stop working altogether) or changing it to Content:// (which has the same issue where there’s no image attachment).

A lot of the tutorials I’ve found online are fairly old, so it’s possible that there’s something in my code that is simply out-of-date.

If anybody has some suggestions on what to change, that’ll be great. Thank you!!

public IEnumerator AndroidShare()

        isProcessing = true;

        string shareMessage = "Test shareMessage";
        string screenshotName = (DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss")) + ".png";
        
        ScreenCapture.CaptureScreenshot(screenshotName, 2);
        
        string filePath = Path.Combine("File://" + Application.persistentDataPath, screenshotName);

        yield return new WaitForSecondsRealtime(1f);

        if (!Application.isEditor)
        {
            AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
            AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");

            intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));

            intentObject.Call<AndroidJavaObject>("setType", "image/png");

            currentActivity.Call("startActivity", chooser);

            yield return new WaitForSecondsRealtime(1f);
        }

        yield return new WaitUntil(() => isFocus);
        isProcessing = false;
    }
