An "extends TabActivity" class can not instantiate methods from other classes?

1

I made some tabs via java code and needed to receive a method from another class that would return an array, scan the array and populate my tabs, but from the "NullPointerException" error and when I make the instance of the same method in an Activity that " extends Activity "works normally.
