You'll need to use a library such as opencsv (found here: http://sourceforge.net/projects/opencsv/)

To write data to a file you'll need to do something similar to this:

String csv = android.os.Environment.getExternalStorageDirectory().getAbsolutePath();
CSVWriter writer = new CSVWriter(new FileWriter(csv));

List data = new ArrayList();
data.add(new String[] {"India", "New Delhi"});
data.add(new String[] {"United States", "Washington D.C"});
data.add(new String[] {"Germany", "Berlin"});

writer.writeAll(data);
