## Public methods

### close

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public abstract void close ()
```

Closes this stream and releases any system resources associated
with it. If the stream is already closed then invoking this
method has no effect.

As noted in `https://developer.android.com/reference/java/lang/AutoCloseable#close()`, cases where the
close may fail require careful attention. It is strongly advised
to relinquish the underlying resources and to internally
*mark* the `Closeable` as closed, prior to throwing
the `IOException`.
