Hi. I've an android 4.2.2 rooted tablet.
Here in Italy we have a mobile phone repair shop. I want to put the tablet in reception and make a mini-website like "find the accessories for your phone" with images and pricelist. For the website isn't a problem, I can install a webserver in the lan, but I want to "lock" the tablet to go only to this site and also lock the launcher to prevent user to go on settings etc.
