5. Callback

---

You will recieve a callback in onActivityResult method

1. If you called the activity for creating pattern, you would recieve the requestCode as REQ_CREATE_PATTERN. Following results are expected:

   a. User set the pattern successfully - in this case the resultCode would RESULT_OK

   b. User cancelled the activity - in this case the resultCode would be RESULT_CANCELED

If you received RESULT_OK, then you are expected to save the pattern

2. If you called the activity for comparing pattern, you would recieve the requestCode as REQ_ENTER_PATTERN. Following results are expected in this case:

   a. Pattern Matched - in this case the resultCode would be RESULT_OK

   b. User cancelled the activity - in this case the resultCode would be RESULT_CANCELED

   c. Failed to identify the user - in this case the resultCode would be RESULT_FAILED

   d. User forgot the pattern - in this case the resultCode would be RESULT_FORGOT_PATTERN
