Android 统一共享按钮实现

我正在尝试实现共享功能，如本博客所示：

但当我尝试在Android上与Line共享时，我遇到了以下错误：

以下是守则的相关部分：

//instantiate the class Intent
AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");

//instantiate the object Intent
AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");

//call setAction setting ACTION_SEND as parameter
intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));

//instantiate the class Uri
AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");

//instantiate the object Uri with the parse of the url's file
AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse","file://"+pathName);

//call putExtra with the uri object of the file
intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<AndroidJavaObject>("EXTRA_STREAM"), uriObject);

//set the type of file
intentObject.Call<AndroidJavaObject>("setType", "image/png");

//instantiate the class UnityPlayer
AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");

//instantiate the object currentActivity
AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");

//call the activity with our Intent
currentActivity.Call("startActivity", intentObject);

我已经花了两天的时间来寻找解决方案，任何形式的暗示都将不胜感激！即使这意味着我需要尝试其他方法来实现此共享功能

非常感谢

您是否授予外部播放器设置的写入权限？尝试执行此操作，否则图像将无法创建！：D
