I'm wondering if any of you know of an app I can use to have my Android phone stop the music player when I turn the power off (power coming from cigarette lighter socket) after I turn the key and have it start playing again when I apply power (start the car with the key?) I had an old iPod I could make do this. I always left it in the car hooked up to the cigarette lighter and with the 1/8" connected to the AUX input on my car stereo. I can't find a way to do it with an old android phone though. My old car doesn't have Bluetooth, because I know that it's possible to do it that way. Any ideas?
