android SharedPreferences or sqllite -

If I want to save large apps like RSS feeds or topics in my app

To use Sqlllite or sharePreferences

Share information as SharePreferences shared information? Like any other app you can use?

In this case you have the SQLite option, which is a large amount of data , While shared preferences were designed to store the key in relatively small amounts in a size pair of pairs.

No more name is a bit confused but it means that those preferences are shared with all your app activities and not for other applications.
