java - Need a ContentProvider to access SharedPreferences -

i dont need code this, structure of doing it.

i working on application have baseativity (extends activity) number of methods , inner class user. other activities in application extends baseativity.

the user class has methods read , write data using sharedpreferences. loginactivity extends baseactivity, , upon correct login calls user.login(args) in order create shared variable (in mode_private) user id, user email, , json user preferences.

i need create content provider use query() retrieve data logged in user. content provider data sharedpreferences , provide them appalication calling content provider.

since content provider extends contentprovider not able extend baseactivity (that solution). when calling within contentprovider's method oncreate()

user user = new baseactivity.user(); 

i error .... "'com.example.myapp.baseactivity' not enclosing class".

is there way call inner class user contentprovider?

if need access sharedpreferences contentprovider, don't need contentprovider implement sharedpreferences, because getsharedpreferences() method of context available getcontext() method of contentprovider class.
