unity 调原生Uri intent等

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");

            AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
