I have a problem in my android application, I have a hand page, I change my business with 

startActivityForResult (intent, CODE_DE_MON_ACTIVITE).

It works, but then when I replace this page since the second activity with the same code but nothing works. The application crashes.
Knowing that I have all the activities in the Manifest.

Log:

    Have you actually assigned a value to the Intent? Simply coding Intent intent; will throw a NullPointerException when you call startActivity(intent); like the one you got. Alternately, have you added your second activity to the Manifest file? Android won’t launch an Activity that isn’t in its Manifest.
