XmlWriter.Create exception, "Could not find the file..." on Android

Hi all,

I have some C# code which is throwing the above exception when I call XmlWriter.Create. I've tested on Windows and Android and have only seen this happen on the latter.

My first thought was that the directory didn't exist so I added a Directory.Create call above it. No dice.

Next I thought the file, if it already exists, might somehow be in use. To try and catch this I added a File.delete call expecting that to generate a similar exception before my call to XmlWriter.Create. Again, no joy.

I also tried placing the call to XmlWriter.Create in a loop so that it keeps trying till it succeeds. I found that if the call fails (it doesn't always) it only fails once then works on the second go round the loop.

Here's broadly what the code looks like;

         string path = GetFilePathWithExtension();
         string dir = Path.GetDirectoryName(path);
 
         if (!Directory.Exists(dir))
         {
             Directory.CreateDirectory(dir);
         }
 
         File.Delete(path);
 
         for (int i = 0; i < 10; ++i)
         {
             XmlWriterSettings settings = new XmlWriterSettings();
             settings.CloseOutput = true;
             try
             {
                 using (XmlWriter writer = XmlWriter.Create(path, settings)) // Exception thrown here
                 {
                     Save(writer);
                     IsDirty = false;
                 }
 
                 break;
             }
             catch (Exception e)
             {
                 this.LogError(e.Message);
             }
         }

And here's the text of the exception;

"Could not find file \"/storage/emulated/0/Android/data/com.guycorbett.theadventureengine/files/libraries/local/official.libraryinfo\""
