Unity Android - 图片分享到 Facebook 失败

Question

我最近在 Play 商店发布了一款游戏。在游戏中有一个分享按钮，它使用资产中的宣传图片，添加一些文本并使用 Android 本机分享实用程序进行分享。我知道 FB 不允许为用户输入文本，但图像总是无法添加到 post.

我已经为这个问题绞尽脑汁好几天了。我安装了 Facebook sdk，它本身并没有解决问题，但我不确定如何继续希望按钮允许用户在共享时选择要使用的服务，而不是仅仅使用 facebook sdk 共享.

这是我使用的代码：

yield return new WaitForEndOfFrame();
    if (!Application.isEditor)
    {
        string fromPath = "jar:file://" + Application.dataPath + "!/assets/";
        string toPath = Application.persistentDataPath + "/";

        string[] filesNamesToCopy = new string[] { "a.txt", "b.txt" };
        foreach (string fileName in filesNamesToCopy)
        {
            Debug.Log("copying from " + fromPath + fileName + " to " + toPath);
            WWW www1 = new WWW(fromPath + fileName);
            yield return www1;
            Debug.Log("yield done");
            File.WriteAllBytes(toPath + fileName, www1.bytes);
            Debug.Log("file copy done");
        }
        // code to open the image and share it
        AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
        AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
        intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
        AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
        AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse", "jar:file://" + Application.dataPath + "!/assets/" + "Promo.jpg");
        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);

        intentObject.Call<AndroidJavaObject>("setType", "text/plain");
        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), "I scored " + score + " in Space Drill, try to beat me! #spacedrill https://play.google.com/store/apps/details?id=com.AbsinthePie.space_drill");
        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), "SUBJECT");

        intentObject.Call<AndroidJavaObject>("setType", "image/jpeg");
        AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");

        currentActivity.Call("startActivity", intentObject);
    }

任何提示或建议将不胜感激。感谢阅读！

试试这个：

Texture2D tex=new Texture2D(width,height,TextureFormat.RGB24,false);
        tex.ReadPixels(new Rect(startX,startY,width,height),0,0);

        tex.Apply();

        byte[] dataToSave = tex.EncodeToPNG();
        grab = false;
        string destination = Path.Combine(Application.persistentDataPath,System.DateTime.Now.ToString("yyyy-MM-dd-HHmmss") + ".png");
        File.WriteAllBytes(destination, dataToSave);

            AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
            AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
            intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
            AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
            AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse","file://" + destination);
            intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);
            intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), message);

            intentObject.Call<AndroidJavaObject>("setType", "image/jpeg");
            AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");

            // option one WITHOUT chooser:
            currentActivity.Call("startActivity", intentObject);
