Rooted Phone: Apps have root permission
<p>I'm developing an app that (I believe) needs root privilege.  There are plenty of instructions on the web for rooting a phone.  My questions is:</p>

<p>If I root my phone, do all apps get root privelege automatically, e.g. a File Manager or ADB?</p>

<p>(I'm familiar with root privelege on desktops, but Android is a different animal).</p>

<p>A previous answer from "Ali" said to "acesss [the app] in SuperUser".  I'm not sure what that means.  Do I have to mod my app? Do I launch it differently? or what?</p>
