I'm injection a constant String into a provider to configure some
info, but I don't want the constant to be required. Thus I'd like to
make it @Nullable so that I can use a sensible default if one isn't
provided.
public class SharedPreferencesProvider implements
Provider<SharedPreferences> {
protected static final String DEFAULT = "default";
@Inject @Nullable @Named("sharedPreferencesContext") protected
String context;
@Inject protected Provider<Context> contextProvider;
public SharedPreferences get() {
return contextProvider.get().getSharedPreferences(context!
=null ? context : DEFAULT, Context.MODE_PRIVATE);
}
}
Seems pretty straightforward, but I keep running into the following
exception:
E/AndroidRuntime( 803): com.google.inject.CreationException: Guice
creation errors:
E/AndroidRuntime( 803):

Am I missing something?
Cheers,
