Am working on a wearable using Arduino Micro and I am thinking it would be cool if I can trigger some events in my smartphone using Arduino. Say for example a button press in my wearable should trigger events like opening music player, reducing/increasing volume or opening some Android Apps.
Sorry for providing just a rough view of the idea. So I want to know to perform similar actions listed above, Do I need to create a Android app for it? I don't find any readymade app that fits my requirement. Or Is there any feasible way to achieve what I need without having to break my head with Android developing?
Thanks in advance.
