After you copy the file (as @barmaley's great answer shows), don't forget to expose it to the device's gallery, so the user can view it later.

The reason why it has to be done manually is that

Android runs a full media scan only on reboot and when (re)mounting the SD card

(as this guide shows).

The easier way to do this is by sending a broadcast for the scanning to be invoked:

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(outputFile));
context.sendBroadcast(intent);

And voila! You can now view your file in the device's gallery.
