 So, our idea come up with a live example from where in offices or in a meeting sometimes we forget to silent our phone or just to change the profile of our phone and it rings in a meeting or somewhere. Or we are showing somebody something on our phone and we have some of our personal pictures as a wallpaper and we don't want to show other people them. So, we have come up with the idea to change the profile of the phone as soon as we enter our office premises or anywhere else we want to change our phone profile. So, using this idea we are making our application. So, say we are in our office and using NFC we can change our device profile with a single touch. So, we don't have to go into audio settings or our display settings to change separately. So, for now we are doing it for wallpaper and ringtone and volume. We are planning to do it with Bluetooth low emission technology as well. But we don't have any beacons for it so we are just not trying with NFC. Currently we are facing a problem with getting the path of the audio file because different android versions and the path of the file is getting changed and so we are trying to get a optimal solution of it.
