Simple Android APP Kiosk System

Hi! I need a developer fo an android APP with the following features: - the APP will be installed on an android TV-Stick - after powering the stick the app will directly start without navigating to the android desktop - after the very first Startup the app asks the customer to choose the wlan and enter the password for this wlan - this data will be stored and every time the app starts again it opens a special URL in fullscreen-Browser-Mode from the chrome browser - only if the Wlan is offline it should again show the screen with the "choose wlan" and enter wlan password We need the possibility to change the URL for each installation. The apk will not be in the app-store. We will install the apk by hand on each android-tv-stick and then need to be able to change the url of the fullscreen browser also by hand for each stick (e.g. in a text file). The easiest solution please! thanks for your offers!!!!!
