I don't know much about it but as the documentation says that your application should be run only with Alexa wake word which means that there should be a background service which continuously should run and the microphone too. As the microphone is given Alexa word as an input , the app should run but that would very costly (in my view) with respect to android hardware resource as you would have to run a background service which is continuously taking input voices and checking for wake word in it. Plus you also might have to run continuously a Speech-to-Text conversion for checking the Alexa wake word.
