Headphone indicator — Open Source Productivity App

Shows a notification icon in the status bar when headphones are plugged into the phone. Shows a different icon when a headset is attached. Both 3.5mm audio jack devices and USB headphones/headsets are supported. The app aims to be a tiny as possible. No ads, no analytics - just its core functionality. After installation, you have to start the application at least once. Then it will be running as a background service that shows the headset status icon whenever the headphones are plugged in. I wrote the headphone indicator app because I was immensely unsatisfied with apps like (google forced me to remove the name) which are over 2 MiB in size, but 99% of their code is only related to advertisement. Open Source - licensed under the GPLv3+. The source code can be inspected by anyone.
