Control default contact list and messages app
<p>Is there a way I can control what contact list and messages show? I want to make an app that if enabled will hide certain contacts or messages from certain people. I am not sure of this is doable
Please let me know if this can be done programmatically. Please note that I am referring to the default contact/messages APP that comes with android and I want to be able to control what it shows from my app</p>

<p>Thank you </p>
