If you want to avoid this error on simulators, you should read the InputStream one byte at a time, try this code (consider NOT using this method when working with a real device, since performance will be affected):

    InputStream is = httpConnection.openInputStream();
int data = -1;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
data = is.read();
bos.write(data);
while (data >= 0) {
 try {
  data = is.read();
 } catch (Exception e) {
  // Replace exception with "-1". This is to handle anomalous End-of-Stream in OS 5.
  data = -1;
 }
 bos.write(data);
}
byte[] byteArray = bos.toByteArray();

If you are seeing this error message in a simulator, don't be surprised. I see I/O errors like this quite often in simulators, especially over Direct TCP or Wi-Fi connections. Some of the newer 5.0 simulators seem to be more problematic than older ones.

If you haven't yet, try it on a real device and it will probably be better.
