Simple Browser

I just need a simple android app to use on a 7inch table able to open a fixed website based on a system parameter that I should be able to set. The application shall display the website on full screen and without any kind of button or navigation bar. Simply the app shall render the website every time that is open and display the content as any normal browser. If is possible, the app shall prevent the phone to lock or suspend (no concerns for battery time - tablet would be plugged all time and I want to keep the screen always displaying the website) As a summary: The app must: -be able to render a website -display the website on full screen -display NO buttons or navigation bars -fixed website shall be defined by a system parameter (during installation or preferably as a parameter in an INI or XML file inside the phone) The app could: -prevent the phone to be locked or suspended -hide android buttons Please note that this functionality is for an internal implementation, no need to follow Android standars or concerns about being approve by Google Play. Just need the app able to upload on a tablet or phone.
