a persistence and startup service to support an app
<p>I own an android 4.0.3 tablet and I'm programming in Java/SDK, still not tried NDK.
Now, suppose that you want to program this tablet to put it in a service point, with a single use case, like a restaurant, where it would show menus and let the user pass them. I would like not to let the user to shut down this software. Also, it must automatically runs at tablet start up and persisnts on, i.e. if it shuts down by some reason, the tablet should not go back to its standard GUI but to restart this application.</p>

<p>I don't know any start point for this, like some keywords etc. I imagine that here I must code a service (that maintains the persistence and startup of the application) and the application itself.</p>

<p>Could you please give some ideas / keywords / potential start points / comments?</p>

<p>Thank you in advance.</p>
