I have the normal 'Phone' dialer and I have new 'Dialer' app. Now if I check the "Use by default for this action" and click on the 'Dialer' app then every time when I press the phone button the 'Dialer' app will be started automatically. But how can I change this in code ?

Where this preference is stored ?
