Broadcast receiver for insertion into contacts

I try to launch the application after successfully saving the contact in androids in the built-in phone book. so I want to know if there is a broadcast receiver for updating in the phone book and adding new contacts in the phone book.

Or any other way to find the add or update event in the phone book.

You need to implement the Android service and register the observer in the contact list, you can turn to this issue to receive the change event in the Contact Change phone book . After that you can launch the application. You can start your service when you reboot the device using the brodcast receiver to boot.
