Permanent android developer needed

I need an app developed for both platform. It is a very simple app and the UI is going to be just one simple button that can perform an action and change color depending on the state of the device it is taking to. Communication between the app and the device needs to be encrypted. The app needs to have a configuration page where network settings and and will need to have test communication function to ensure it can talk to the device. App should be password protected. The main action when the button is clicked is to send a signal to a micro-controller to tell it to perform a single task (more on this later). Button also acts as an indicator to the user the status of a device connected to a micro controller and changes color based on the state of the device. Green means GOOD state. Red means NOT GOOD. Communication by the way needs to work either through wifi or 3G and device. LOW BIDS WITH GOOD SKILLS WILL BE GIVEN PRIORITY..!!!!!!!!!!
