cursorLoader incompatibilita' v4

[ndrokki]

EDIT: Funziona
Nella main class invece di getSupportFragmentManager,ho usato getFragmentManager
poi ho cambiato
initLoader(0, null, this) a intLoader(0,null, (LoaderCallbacks<Cursor>) this


Ciao non riesco ad usare initLoader il problema principale e' che non accetta come terzo parametro this
se non levando gli imports e mettendo le librerie support v4, ma a quel punto non posso piu' ritornare un cursore, e mi fa implementare nuovi metodi l'interfaccia che in OnLoaderStart non mi fanno ritornare un CursorLoader, cosi faccio a meno dei v4 imports, ma ottengo un errore che non riesco a spiegarmi nella main class, cercando in giro ho trovato che gli import potrebbero essere sbagliati, ma sono giorni che provo senza successo.
Uso android studio intellij e la minsdk e' 11
grazie

RiSOLTO
gli import alcuni erano per le librerie retrocompatibili V4 altre per quelle normali
per cui invece che usare getSupportFragmentManager ho utilizzato getFragmentManager, cancellando tutti gli importi ed aggiustandoli uno per uno
