How to change an arrayList once a app is deployed?

I would like to change the value of a ArrayList once a application is deployed. I want to be able to change it monthly.

I thought hosting a text document on my website.. Reading from it through the application and set the values to variables and set the variables to the ArrayList.

Would this be a good way to go about doing this? Or is t开发者_如何学JAVAhere a better way?

If you don't want to update the app every month, I guess that would be a simple way of doing it. In your case, I would use a HTTP Post service. This guide and this one here might help you.
