The default value for resultCode when activity ends

Question

This may be a basic question, but I hope to get some clarity.

What I'm trying to do: 1) Starting an operation using requestCode and processing two operations in onActivityResult, one uses RESULT_OK, the other uses RESULT_CANCELLED. I clearly indicate each of them.

The problem even is that I close the activity only with the "Back" button and without setting any result, the "Activity" activity in the back stack gets RESULT_CANCELLED.

After going through the source code, I see that RESULT_CANCELLED is the default value for the result code and that the return code is always sent back.

I read this right, and this is what happens all the time? or am i doing something wrong in my application?
