The idea here is to share what you've done with your Android radio and to talk about how. There's a ton of information here about the installs, speakers, and amps. But I'd like to hear more from the community about how they're making their Android radio experience their own.
For me, I just yesterday discovered a widget for my home alarm system app. Like nearly any smart home interface, our alarm system app allows custom 'scenes'. I have one that sets one of 2 thermostats (where I spend most of the day in a home office). It opens our electric gate, and disarms the alarm system. I use this every day at least once. It's super nice to have the gate open, alarm not screaming on entry, and at night, when the opened gate triggers the perimeter and garage lights, a nice, bright path to the door.
The widget prevents me from having to open the app, navigate to the scene I want, and then confirm I wish for it to do what I have asked. Pictured below, the widget when pressed simply triggers a visual outer circle on the icon and begins the routine. This is WAY easier than the multiple clicks above while driving.


Another handy widget is the one for the I-Bus app. Shown to the right above, it populates the items I select from within the app and displays them on a smaller section, sharing the home screen with my other most often used items.
Finally, I really do like the Google calendar widget. We've been running off a calendar for family events like sports, dances, dates, dining, dalliance, and pretty much every other thing we do around here. It's great to see the calendar updated automatically as you start out and about for the day.
Then there's Torque. I have only recently been working with it, but I would like to create an environment where it periodically uploads trip data. I would like to retrieve it and analyze it- or at least know that I can. I see custom widgets for it and have no idea how to make the best use of all the data we have access to. If anyone can offer step x steps on the first cool things to get that started, I'd like to see that here.
So what're YOU doing with your Android head unit that you really like? What do you use *every* day beyond what comes with it? And if your application is standard, how are you using it and finding it so cool day after day? I'm dying to learn more about what others find cool.
