What is the difference in usage between performClick() and callOnClick()? It seems that they work the same way, then why does View have two methods?

Performs all normal actions associated with clicking: reporting accessibility event, playing a sound, etc. Directly call any attached OnClickListener. Unlike performClick(), this only calls the listener, and does not do any associated clicking actions like reporting an accessibility event. MH.
PerformClick rather than invoking the click event of a button directly. The MSDN documentation simply says: Generates a Click event for a button.
The Javadoc for both methods is pretty self-explanatory too:
public boolean performClick () Added in API level 1
Call this view's OnClickListener, if it is defined. Performs all normal actions associated with clicking: reporting accessibility event, playing a sound, etc.
public boolean callOnClick () Added in API level 15
Directly call any attached OnClickListener. Unlike performClick(), this only calls the listener, and does not do any associated clicking actions like reporting an accessibility event.
