This piece of code works for me.

Thanks and Regards

String filename = "test"+ System.currentTimeMillis()+".txt";
ArrayList<String> report = new ArrayList<String>();
report.add("Hello");
report.add("How are you");
FileOutputStream fos;
try {
fos =
openFileOutput(filename,Context.MODE_PRIVATE);
ObjectOutputStream out = new ObjectOutputStream(fos);
out.writeObject(report);
out.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
