  • Please paste the line 99 of your MainFragment.java ... – Thomas Mary Jan 24 '18 at 21:37
  • I find it best to use a `public static final String` to maintain consistency for names of extras! It looks like you have used to different strings: "row_s" and "row_S" (capital "S"). Besides that it also looks like you have not assigned a value to your variable "valor3". – Barns Jan 24 '18 at 21:59

Your parameter is null because the name of the key must be the same

for example, in your first activity you have:

intent.putExtra("row_S",valor3);

the name of the key is: "rwo_S" with the capital letter S

and in the second activity you have:

recibeBundle = getActivity().getIntent().getStringExtra("row_s");

the name of the key is: "rwo_s" with minuscule s.

The name must be the same.

I hope it helps you.
