I’m developing an Android application using Xamarin.Android, hence I’m using SendBird’s .net library. I have implemented a function to send a ‘FileMessage’ (image, in particular) from local phone directory path. The issue I’m having is when I’m trying to display the ‘FileMessage’ in ‘OnMessageReceived’ event in the ‘ChannelHandler’. I was able to get the URL of the ‘FileMessage’ in the said event, but I can’t access the stream from the URL.

Here is the function that I use to access the URL:

```
private byte[] getBitmapFromURL(String src)
        {
            try
            {
                URL url = new URL(src);
                HttpURLConnection connection = (HttpURLConnection)url.OpenConnection();
                connection.DoInput = true;
                connection.Connect();
                Stream input = connection.InputStream;
                MemoryStream memoryStream = new MemoryStream();
                input.CopyTo(memoryStream);
                return memoryStream.ToArray();

            }
            catch (Java.IO.IOException e)
            {
                e.PrintStackTrace();
                return null;
            }
        } 

```

The function above throws an IOException when it reached connection.InputStream:  
{Java.IO.FileNotFoundException: [https://file-ap-9.sendbird.com/bcb2d8e2a41a4561b4608e09a8c81313.jpg](https://file-ap-9.sendbird.com/bcb2d8e2a41a4561b4608e09a8c81313.jpg)

}

Here are some details from the FileMessage that I could see when I debug my program:

Please let me know if there is any specific way to access the image stream from images uploaded to Sendbird, or if there is anything else I could provide.

I have the same question and do not see this subject in the [SB.NET](http://SB.NET) documentation.

I want to be able to download the image from FileMessage.URL.

It seems like I am missing a [SB.NET](http://SB.NET) SDK method call that would be used specifically for this. If I try to just download the URL, then I get access denied.
