  Yes I did that but I am having an exception while querying currentFs.Capacity in the below code :

          UsbMassStorageDevice[] devices = UsbMassStorageDevice.GetMassStorageDevices(Global.MyActivity.ApplicationContext);
  
          foreach (UsbMassStorageDevice device in devices)
          {
  
              // before interacting with a device you need to call init()!
              device.Init();
  
              // Only uses the first partition on the device
              IFileSystem currentFs = device.Partitions[0].FileSystem;
  
              Console.WriteLine("Capacity: " + currentFs.Capacity);
              Console.WriteLine("Occupied Space: " + currentFs.OccupiedSpace);
              Console.WriteLine("Free Space: " + currentFs.FreeSpace);
              Console.WriteLine("Chunk size: " + currentFs.ChunkSize);
          }

  What version of libaums did you use ? I am using libaums-0.5.0.aar from here : https://bintray.com/package/files/mjdev/maven/libaums?order=asc&sort=name&basePath=com/github/mjdev/libaums/0.5.0&tab=files

  And where did you get the AAR? I cannot find it on the web. Could you please share it?

  Also, I am using Visual Studio 2015, and you?
  Would be great if you could share your 0.5.2 AAR cause I still can't find it on the web.

  Thanks but I built the 0.5.2 AAR under Android Studio 2.3.3, then I did bind the AAR under an Android Binding Library project under Visual Studio 2015 but I am still facing the same exception.

  Do you have an example of a code that works for you when you call the binding library?

  Though I am new to Java I did some modifications to the libaums source code and I got it to work. I am now able to list the content of the root directory of a USB stick, create a foler and a text file Inside that folder.
  But sadly every call to UsBMassStorage.Init() has a bad interaction with my app as it ends in a crash after the several operations on the USB stick.

  I finally found why UsbMassStorage.Init() had a bad interaction with the rest of my code, it wasn't due to the libaums Library.
