Request Code / Request Status See also "Getting a Result From an activity" developer.android.com/training/basics/intents/result.html A request code's purpose is to match the result of a "startActivityForResult" with the type of the original request. Request Code is an integer that identifies your request. On receiving the resultant Intent, request code is provide so the app can properly identify the result and see how to handle it.
RESULT_OK and RESULT_CANCELED do not have to be declared as field variables. Inherited.

//2. Bind request code to the startActivityForResult method.
