    Building an Android frontend

    *Sept 11*
    Hey guys. This post is getting really long and difficult to maintain.

    *April 29*
    I know it's been a while since I've done anything with this, but it's not dead. I've been working on the hardware side of things and been holding off on the software. I've come a long way and plan to get back into the Android side soon.

    Also Github link

    APK is here

    *Jan 1 Update*
    I have added an auto updater portion to this. I am getting a lot of crash reports from people using old and outdated APKs, so now when I push a new one, it should auto update.

    *Update*
    I haven't given up on this. Every time somebody uses my app and it crashes (which seems like a lot...) I do log the crash and am working on fixing it. But my main issue right now is my hardware. I have bought a UDOO board (embedded Android/Arduino board) and it looks great, but I'm having some major issues and am waiting on a fix before I can really get back into the code.
    Thanks all

    -----------------

    Hey everybody

    I have been working on a full hardware solution for my car. The basics of my plan is this. I have a Nexus 7 that will be mounted in the dash, connected via a custom Arduino based hardware board, that interacts with the windows, seat heaters, air suspension etc...

    I have been working on the whole project for a little over three years. So far the front end has built in music capabilities, basic maps and driving directions, some bluetooth support (still very buggy) and a lot of things that will probably only be useful for myself, however a lot of it is pretty ingrained in the code. That being said, I'm working on making the whole project more modular every day.

    I don't know if there is any community interest in this or not, like I said it started for personal use. If there is interest I will happily put the code up on Github and get input from the community. However, like most open source projects personal support will be minimal.

    The entire project is still under heavy development and has a long way to go. I know there is a lot of bugs still to be ironed out, and maybe the community is willing to help with that as well.

    Some screen shots are attached.

    Wow this looks great. Can you give more information on your arduino cobtroller? I want to use an arduino to provide similar functions as you and have it tied to the Can-Bus system in my car.

    I am using Timurs USBROM/ because it is designed for a fixed installation scenario. It will provide USB host mode (using an OTG cable) and simultaneously use up to 1800ma to keep the battery charged.
    Along side that, I have my Arduino running a sketch that communicates with the tablet over USB acting as a master. I also have slave devices (mostly I2C) that are responsible for "getting data" (temperatures, air pressures, etc...) and "setting data" (set air pressure, roll up window, etc...).
    As you can see in the screen shots, there is a display for Inside temperature, and Outside temperature. Those temperatures are read via a temp sensor hooked up to the Arduino and sent to the Droid.
    While the hardware is somewhat functional, my main area of work in the Front end code, and the backend hardware has taken the back seat.

    Initial checkin to Github. Beware there is bugs, somethings won't work easily (bluetooth for example) and somethings may just not work at all. That being said, feel free to try it out. Let me know what you think.

    My note 2 will become the permanant fixture as soon as my note 3 comes in...

    Looks pretty good, like the style

    With Android's range of customizable launchers and widgets, personally I don't think Car Android's need a "front-end" because anyone can make almost any front-end they want. I think if you made some customizable widgets that interface to the arduino, that would expand your market past the 'android-in-a-car' crowd.
    Having said that, I'd probably still use your app cause it looks nice, could do with a Milkdrop type visualizer in the middle.

    Thanks for the input.
    The reason I started this was I wanted an all in one solution that interfaced with all of the hardware like it would in an OEM environment.
    The Arduino integration is something I have working, but haven't figured out the best way to make it modular and easy to use yet.
    In all honesty, this project was designed for me and me alone. That being said I hope somebody else can find it useful too and maybe it can grow to be something useful for a wide group of people.
    As for the visualizer comment, where about were you thinking? Visualizers are something I don't use ever, but I'm not opposed to adding one to make this more fully featured.

    Just an example, would be a lot of work though, and a lot of extra processing on the device.
    After 30 seconds or so of inactivity the big buttons in the middle could fade out, touching the screen would bring them back again.
