Passing bidimensional String Array variable from 1 activity to another

Question

I have a bidimensional String array that has mass data (sizes are [40][8] to be exact) in my Activity A. I want to pass the whole array to Activity B. I've tried this solution: Passing string array between android activities

but the problem is it is creating an array inside. I want to pass my original bidimensional array that contains [40][8] values. Can I do that?

EDIT:

my String array is a 2 dimensional array.

and, which is the problem on creating a new array in activityB? I don't get it — Pier Giorgio Misley

I can create a new array on activity B. the problem is that i dont know how to pass my 2 dimensional array from activity A to a newly created 2 dimensional array on activity B. (the 2 dimensional array on activity B has nothing in it (null) i want to fill it with my 2 dimensional array from activity A.) — Dan Arenas

Since your array is bidimensional and bidimensional array are serializable, you can use a bundle:

Intent intent = new Intent(this, activityB.class);
Bundle bundle = new Bundle();
bundle.putSerializable("myArray", myBidimensionalArray);
intent.putExtras(bundle);

and in activityB you can simply call:

Intent passed = getIntent();
Bundle bundle = passed.getExtras();
String[][] myPassedArray = (String[][]) bindle.getSerializable("myArray");

and you are done
