Question

i have to make an android application in which i need to download a lot of data from the server which is sent to me via XML. i then need to parse the XML and then display the extracted information.

To avoid making the application slow, i have decided to break my XML down into small parts.. so that i can only call the part that i want, this would limit the information that i am receiving.

My question is once that i have parsed the XML data where do i store it ( except for a db ) until my UI is rendered? On the iPhone there is something called user default where in we can store such information. What would be the equivalent in android?

thank you in advance.

You can use application preferences to store data as shown here (if the data is small enough).

Their code sample shows:

SharedPreferences gameSettings = getSharedPreferences("MyGamePreferences", MODE_PRIVATE);  
SharedPreferences.Editor prefEditor = gameSettings.edit();  
prefEditor.putString("UserName", "Guest123");  
prefEditor.commit(); 

I wouldn’t do this for large datasets but it’s a handy place to store data.
This gets removed when the application is removed too.

If you’ve got a lot of data, I’d suggest storing it on disk.
