Sharing an image on Android

Unity Engine

I’m trying to share a screenshot taken in Unity via the Android intent system.

Here’s my code for taking the screenshot:

Application.CaptureScreenshot ("Bla.png");
        ShareImage (Application.persistentDataPath + "/Bla.png", subject, title, message);

Here’s my Android-Code for calling the sharing intent:

    public static void ShareImage(string imageFileName, string subject, string title, string message)
    {
        #if UNITY_ANDROID
       
        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/*");
        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), subject);
        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TITLE"), title);
        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), message);
       
        AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
        AndroidJavaObject fileObject = new AndroidJavaObject("java.io.File", imageFileName);
        AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("fromFile", fileObject);

        bool fileExist = fileObject.Call<bool>("exists");
        Debug.Log("File exist : " + fileExist);
        // Attach image to intent
        if (fileExist)
            intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);
        AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
        currentActivity.Call ("startActivity", intentObject);

        #endif
    }

The result is not was I was hoping for. The share-overlay opens fine, but the image is missing.
By using Android’s debug console I found the following error:

The file seems to exist (fileExist is true), but there is some kind of permission problem…
Can anyone help me out?
Thanks!
