[android-developers] Re: Appending nodes to an existing XML file

Simple, yes, but it performs as O(n^2). As your file gets longer and longer, your application will perform slower and slower. If you don't take care to do it off the UI thread, you will eventually start getting force-closes because it stalls out the UI thread.

Not generally recommended.

All of these solutions have potential issues with incomplete writes, due to the application being shut down in mid-write. 

A more robust solution, also quite simple, is to stick all the data into a database -- and output it as XML at the point you need XML. In most scenarios, this is the approach I would recommend.

Throw away your requirement ("no rewriting of the file") and you have a simple solution.
