Hi All,

I have a doubt that what is the difference between

because when i used both one by one, both worked exactly same.
Please let me know what is the exact difference between these two.

notifyDataSetInvalidated() means that the data inside the adapter is
no longer valid. This will cause ListView to stop populating. There
should seldom be any reason to use it.
