Answer 1

image.compress already writes the image to the file, assuming you gave a correct file name. So use it like this:

   File file = new File(Environment.getExternalStorageDirectory() + "/myimage.png");
   FileOutputStream fOut = new FileOutputStream(file);
   image.compress(Bitmap.CompressFormat.PNG, 100, fOut);
   fOut.close();

Answer 2

As stated in the documentation for OutputStream:

Most clients will use output streams that write data to the file system (FileOutputStream), the network (getOutputStream()/getOutputStream()), or to an in-memory byte array (ByteArrayOutputStream).

Meaning the data sent to the OutputStream has allready been written to your file.

If what you mean is that you need access to the file once it has been compressed you should look at documentation for the compress() method which states:

If this returns true, the bitmap can be reconstructed by passing a corresponding inputstream to BitmapFactory.decodeStream().

So what you need to do is this:

image = BitmapFactory.decodeStream( new FileInputStream( file ) );
