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:

}
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.
