i've published my app AutoBluetooth on Google Play and i would like to share the link with you: https://play.google.com/store/apps/details?id=it.mf.android.autobluetooth
I hope you enjoy the app which allows you to set up some time intervals in which the Bluetooth must be on. Once set the app will take care of enabling/disabling the bluetooth. The app has some logic in it and will detect any device connected, preventing disabling the Bluetooth until the device disconnects.
I developed this app to have BT on when i take my car to and from the office chich occurs usually at the same exact hour every morning.
I would appreciate any suggestion to make the app better.
