title: Benefits of using flush() close() in Android streams?
body: <p>I know the general idea but I'm just not sure if it has an effect since the Android api states following: "Flushes this stream. Implementations of this method should ensure that any buffered data is written out. This implementation does nothing."</p>
  
  <p>This implementation does nothing &lt;-- does that mean its useless to do or am I missing something?</p>
