Simple Android client application

The component * receives input from external USB device or from a single input field on the UI of this application, the received text shall be displayed in the input field, * calls two REST methods on a server with SSL client certificate authentication, * diplays the sent message and the response on the screen, * has a logging framework to log the messages displayed on the screen. The application should start when the device is started and the user should not be able to leave the application. This is not an application for everyone, it will be preinstalled on special purpose devices which will run only this single application. Please check the attached pdf for details, please indicate in your offer if you are not able to implement one of the requirements, otherwise I assume that you can implement all of them.
