Question

I am fairly new at developing for Android and was hoping to get some help with something.

First, just a brief idea of what I am trying to achieve.

Within the app I am developing, the user can create a project profile for each new project he starts. I have already created the code to create a new XML file for each new project which is stored on the SD Card.

Now I want to create a list of the various projects on the main screen for the user to select from, but I’m not 100% sure how to go about this. My first thought was to have an XML file called Projects List which lists all the projects that have been created. But I just can’t seem to figure out a way to update an XML file every time a new project is created, and this is where I was looking for some help.

Can someone please help me to understand how to update an XML file?

Thanks in advance for any replies.

My first thought was to have an XML file called Projects List which
lists all the projects that have been created.

Instead of doing this, why not simply see how many xml files there were created(corresponding to projects created)? I assume that, now, you’re saving those project in a folder created by you on the SD Card so when it’s time to show that information to the user simple check your projects folder, see how many there are(get the names, get a reference to those xml files so you could open them on a user action etc) and present them to the user.

This would be a lot simpler then implementing the logic to update a xml each time the user does some changes to the projects, not to mention the case when the user might delete those xml files when your app is not running.
