Using XML to store data

android, storing-data, xml

Solution

1.) Is XML the best way to database data on android and most efficient in cases where data may be added or altered every second or less then a second.

Definitely not.

2.) If XML is indeed the best for the scenario described in #1, how do I go about setting it up?

If you plan to store data just locally, the best way would be SQLite which works as a local database on every device.

If you later plan to synchronize this data with a central database, you may do this asynchronously within an `AsyncTask` or a `Thread` which would run periodically, but writing each second into a XML file is a bad idea as far as performance goes.

It's probably also a bad idea synchronizing a remote database at each insert/modification/deletion operation as if you had many users you could collapse the remote database.

I think the best approach is (as previously said) having a local database where you would store that data, and implement a webservice in the remote side if needed and use it to periodically synchronize both databases.
