Something that exposes an InputStream on the other hand is indicating that you will need to listen to. File Output Stream String Boolean.

OutputStream out new FileOutputStream EnvironmentgetExternalStorageDirectory getAbsolutePath yourfilename. Once you have ByteArrayOutputStream object in hand then there is a list of helper methods which can be used to write the stream or to do other operations on the stream.
