Do I need manually call close()?

Do I need manually call close() like this?

    // Read inputStream and output to temFile path
    Source source = Okio.source(inputStream); 
    BufferedSource buffer = Okio.buffer(source);
    Sink sink = Okio.sink(tmpFile);
    buffer.readAll(sink); 

    sink.close();
    buffer.close();
    source.close();

Calling buffer.close() will automatically call source.close(). Otherwise, yes, you should close both the source and sink to ensure any resources are released when you are done with the objects.
