Android dynamic auto-complete - minor fix - code attached

I am trying to implement a dynamic autocomplete widget in android. I am done with the major functionalities and the autocompletion implemented is for youtube video search.

When I start typing a letter or two, the auto-completion is not working. But when I type three letters or more it works prfect. It also works when I type two letters and hit a backspace. I do not know what is wrong with the code.

I have uploaded the code here

Experts, kindly guide me. I would be obliged if you can point out where I have gone wrong with the code.

Any help in this regard is well appreciated.

Looking forward, Regards, Rony

Take a look at completionThreshold AKA the number of characters the user must type before getting completion suggestions.
