Using sqlite via content providers provides an easy way to reference records uniquely on a per table basis, android (somewhere) adds a primary key (_id) to each table you create, this means that each query can return an ID, this can be used to delete and update records by simply appending the id to the content uri.
Like this, assume ID = '1'
getContentResolver().delete(
Uri.withAppendedPath(CONTENT_URI,"1"),
null,null);
What I am curious about is, is this ID reliable to use across sessions, is it added by Android or SQLite? It seems to work but I haven't been able to find any documentation on this.
