SQLite is a database and provide the advantage that you need to get from the database.Shared Preference can stores some values as string,long,int,boolean...You can use this if you need to store some unstructured data that actually not related to each other.On the other hand file has its traditional features.I think it depends on what kind of data you want to store and for what purpose and also What is the relationship between your data.You have to choose according to your situation and needs.
