Database vs filesystem which one is best on Android? Do we have any gallery app for holding list view of pictures and names which loads and unloads images dynamically as and when the item is displayable on screen ?

Question

I am new on android and building an application which uses webservice to collect user information in XML. I also get path for a small jpeg picture of each user. (Currently there are about 200 users)

I am parsing the XML and storing the information in SQLiteDatabase. Pictures are stored as blob and able to retrieve them. I display names of users on listview with images as well.

But is this a good solution for storing pictures in SQLite Database ? Or should consider storing it in file system ?

Which is suitable in terms of performance , as well as memory and any other pro and cons on Android.

Also like to know which is best performing XML parser for Android ? My purpose is only to parse xml files which I get through web services and sort out the data to store in storage.

And lastly my memory goes off easily when I load all images to display in list view after making thumbnails of each (which is obvious). Was wondering is there any library/framework/app available which dynamically loads images as and when required (when that list item is on display) something like Gallery program ?

Any help highly appreciated. Thanks.

I will not answer your question, but have you seen this presentation? http://www.scribd.com/doc/16917367/Coding-for-Life-Battery-Life-That-Is

XML will eat alot of battery power to parse.
