| public boolean | isAutoStart()Returns true if this view automatically calls {@link #startFlipping()}
when it becomes attached to a window.

// OK, this is gross but needed. This class is supported by the
// remote views machanism and as a part of that the remote views
// can be inflated by a context for another user without the app
// having interact users permission - just for loading resources.
// For exmaple, when adding widgets from a user profile to the
// home screen. Therefore, we register the receiver as the current
// user not the one the context is for.
