                                              Parcelable state)

Save the state of the given view and the other state inside of the returned Parcelable.

Returns:

A parcelable containing the view's state and its super state.

<T extends View> Parcelable restoreInstanceState(T target,
                                                 Parcelable state)

setEnabledForAllActivitiesAndSupportFragments

void setEnabledForAllActivitiesAndSupportFragments(Application application,
                                                   boolean enabled)

Turns automatic instance saving on or off for all activities and fragments from the support library. This avoids manual calls of saveInstanceState(Object, Bundle) and restoreInstanceState(Object, Bundle), instead the library is doing this automatically for you. It's still necessary to annotate fields with State, though.

The best place to turn on this feature is in your Application#onCreate() method.

Parameters:

application - Your application instance.

enabled - Whether this feature should be enabled.
