Android In-Vehicle Infotainment

So I've had a project for the last few months getting Android running as an infotainment system. Here is a demo i thought i'd share with you guys..
http://www.youtube.com/watch?v=fNcDq9S8n3I
Basic features:
Android 2.1 (looking to update to GB)
7inch touch-screen (800x480)
3G modem
GPS
Reverse camera (backup camera to see what's behind you)
USB port
would love to hear some criticism or anything regarding the device.. its not perfect, its got a few bugs and glitches.. but is sort of ready for everyday use but is missing a few components to make it 'official' android device (wifi, bluetooth etc).. but i'm just wondering if anyone is interested in something like this? Is this worth developing further on?
This thing runs on Cortex a8 omap3530 board and is based off 0xdroid build.
apologies if im in the wrong forum

Wow dude, thats really cool! I'd love one of these for my car. If you could get Honeycomb on that bad boy it'd be sweet! Just wondering, how do you plan on setting up a rear view camera? Just connect a camera at the back of the car to the tablet itself, then run the Camera app? Seems like the simplest way to me..

Haha cheers love to see the honeycomb source once its out then we'll talk although I'd imagine i'd need better hardware...
currently camera is interfaced by usb (has a usb hub) so i got a cable running under the carpet through the boot then camera is mounted on the bumper. yup camera is called by any camera calling intent.. so any app can use it.
I want to get some proximity sensors (like parking sensors) and write a proper reverse cam app to complement it. But we'll see...

Very cool!
I've been wanting to do this for a while, but I was going to use MeeGo or maybe Moblin since I don't have the programming skills (or Android knowledge for that matter) to build my own computer around Android. I dig what you got so far though.
My suggestion for the reverse camera is one of two things, because it would bug me to have to find and open the camera app every time I needed to back up.
Keep your touchscreen (what model are you using BTW?) and use a bluetooth or wi-fi relay (I know they make 'em, but they are $$$) to provide an input from +12V signal from your reverse light wire to automatically open the camera app, then close the app. Of course, you'd have to program for that.
Or
Have you considered this touch screen? Lilliput 7" touch screen with auto-reverse input. (Needs a RCA camera though)
http://store.mp3car.com/Lilliput_629GL_70NP_C_T_7_VGA_Touchscreen_w_Aut_p/MON-016-0002.htm
This is the one I plan on using since it switches automatically to the camera input whenever you are in reverse. Once you go back to any other gear, the OS input shows up again.
Just a thought to make life a little more convenient (although you already bought your parts so you may be stuck.)

Thanks a lot! It needs a lot of time and dedication but it's a real good learning curve. I had to learn a lot of things on the way.. especially c/c++ I wasn't great at but had decent skills with higher level programming.
If you are planning to work with MeeGo its a little fussy with the hardware requirements.. Correct me if i'm wrong, but I think you need an Intel Atom processor. These are a little pricey if you're after an evaluation/hackable kit! But I'd imagine it'll be easier to program as it's a lot more closey coupled with linux.

I just had a look at those relays, sounds like its something I really need! Is this how the standard backup cameras work? That was something I was confused about.. I wasn't sure how to detect if i'm on reverse.. especially with the parts I already had. I'd imagine once you implement it you just need a service running in the background to listen for the relay.
The touchscreen is a TFT resistive 4wire touch-screen. It's not something I want to keep as I really want capacitive multi-touch.. But this fits perfectly with the board and was easier to deal with

I think most factory backup cameras use two inputs and switch between them. I don't have a lot of experience with them though.

Not sure what you mean exactly. I'll try the relays because it at-least gives me a standard interface to work with (bluetooth or wifi) so there isn't any work you have to deal with on the hardware abstraction.. Although it would probably be better designed if I had some sort of voltage input coming when the vehicle on reverse (the reverse light as mentioned). But I don't really have the electrical expertise to make it happen lol.

Well essentially what I was thinking was you'd have the bluetooth relay hooked up to your reverse light wire. This should allow your computer to monitor whether or not your car was in reverse. Relays are pretty simple - one input switches on/off another, usually one of a much higher or lower voltage. So in essence, it's a switch activated by voltage. (There used to be an electromagnet inside that physically moves a piece of metal to make a connection when a voltage is applied - now it's all transistors and whatnot.)
So, if you are in reverse and your reverse lights are getting power, the bluetooth relay should sense that and signal the computer (through a serial command it seems) which in turn could tell a background service to open the camera app. Once the voltage from the reverse light wire is lost, the relay should again tell the computer that you aren't in reverse anymore and the background service would close the camera app and re-open whatever app you were in.
*I should note this is all "in theory"... I don't know exactly how those wireless relays work/communicate and I don't know Android programming at all.

Thanks for the feedback. I was thinking what about using the GPIOs on the board and attach that to the reverse light? would that be possible? and using some resistors on the way to limit the voltages so i don't fry the board.. but we just need to detect some voltage input...
Not sure, will look into it. Right now, taking a pause on the development.. Got a lot of work to take care of but I can't wait to get back into it. I really want to port this to gingerbread.

You could possibly do that, a real cheap voltage regulator would probably be better though. You could also use a cheap relay if the correct voltage is already somewhere on the car. Again, I'm not too sure how those bluetooth relays work, but it sounds like you are on the right track.

Great Job!
I was thinking of doing something similar myself.
I am looking at going with one of the tablets as it is just seems easier? I only really need internet, google maps(GPS) and wifi tethering. I would imagine you are running stereo sound from a 3.5mm? I would still have a seperate head unit to control volume and handle all the regular functions as well as inputs from a 3.5 to RCA cable.
How are you running sound off that setup? Are you running a head unit still?

The sound is running off a small amplifier. then RCA to 3.5mm.
Haven't had the chance to play around with the wifi tether as right now i don't have a wifi card.. It would make sense to have wifi tethering or just wifi reciever and use a phone to tether 3g to the system. Avoids having separate data plans.

Can we get a copy of your "AIVI Car Home" for our own DIY projects?

I don't mind releasing the source for it. Its just right now its a bit messy and quite a few things are hardcoded.

Nice project. I gutted a Clarion Mind last year to do pretty much the same thing but am looking to upgrade. You said the software needs work but it's a real good start. Would you mind sharing your hardware list with us?

Nice work!

Something I was also interested in seeing is having vehicle manufacturer recommended service intervals and such available as reminders from your in car system or phone or both.

You could use 'aCar' which, if you are unfamiliar, you enter the make, model, mileage and all the pertinent service requirements. Battery every 3 years or 50,000 miles, coolant every year or 15,000 miles, oil every 6 months or 3,000 miles, etc. Then, every time you get gas you enter the current mileage as well as gallons/liters of fuel and the price. From that information you not only get your MPG but it will also trigger reminders to do the necessary maintenance at the correct intervals when they come up. You can do this for multiple cars as well. It's a very good program.
On a related note to this thread, I started my own 'carputer' project using an Archos 70 Internet Tablet and an unused articulating wall mount for TVs. It's still a work in progress as well since I don't have all the parts yet but will do everything I wanted (eventually... lol) except the rear facing camera. The video is obviously just of the media player.
I shot this late last night to show a friend. He wanted to know why someone would want a tablet/computer in their car, lol. Sorry about it being so dark.

Dude
I am keen as mustard on one of these beauties, I was considering running xp MCE but the android option would be much nicer..
Love ya work.

Ok, this is very nice.
I think if this construction works on Galaxy S then its able to make Fotos in the Dark.
I think i would test it an report.
greetings Dimes

I think that a plug with the shape of an inverted L would fit nice.
Like this crappy paint picture.

Remember that link is for mini usb, galaxys s has micro usb.

If anyone manage to turn on/off by software using USB host mode, then you can modified adroid camera AOSP for take photos with flash

good idea this great

wow!Tutorial?!?!

Here is an english translation of the German instructions under the video.
Hope my english is good enought for you to understand.
Its all he wrote, i cant explain it, i just translated it for you.
Edit:
The cost of the flashlight are at ~12€.
There was no tutorial, i had to plan and calculate all by myself.
Expenditure of time: About 2-3 hours of planning and 2 hours 14 min to attach it.
Preamble: Such a big change can destroy your phone and expires your warranty.
Here a few tips, its a bit complicated.
1) At first you have to search for space to place the LED (FLAT-LED 3W ca.8X8mm) and the cooling (self-adhesive aluminum foil) with 0.2mm two-cut and at least a face of 6-8cm². (Dont forget the heat transfer paste ) but be carefull not to glue it over the external antenna or lay any wires next to it. You should also pay attention, that the shine doesnt get into the lense of the camera, because the pictures would be foggy.
2) The LED must be adjusted to the electric tension of the battery
(in the best case led tension= battery tension+0,1-0,2V).
For example: battery 3,6V LED 3,6-3,8V
In 90% of the cases you wont need a multiplier (series resistor) which also should be cooled and have enought space (Low ohm resistors wont need a cooling)
3) Search for some space for the button where you can easy press it if you make photos.
(He used a „subminiature-smd switch“ , you can see the button in the video)
4) The LED shouldnt activate itself if it lays on the back for example,
because it will overheat your device in a short time.
5) Never look into the LED from a short distance, because it can damage your eyesight
6) Dont use the LED when you are charging your battery, because the charge-processor will calculate wrong or your battery will get damaged.

[REQUEST] A patch (kernel?) to disable the htc car-mode switch event.

Hey guys,
I have an evo that has a weird glitch with the USB port.
It seems, anytime the weather is humid, my phone will sparatically start switching in and out of car-mode repeatedly. This has been causing my phone's cpu use to spike, screen to turn on randomly, and worst of all - when the phone is in car mode, I lose control of changing media volume with up-down switch, it forces dock volume.
From what I've found online, car mode is enable/disabled with the 4th pin going to ground in the USB port, which apparently my phone has been finding a way to bridge sporadically.
There are plenty of solutions that say 'delete the apk for the car mode app', but it'll still make me lose control of audio volume, and always be in speaker mode in calls.
Other than this problem, my phone works perfectly normal.
So, is there a way to prevent this pin from being picked up by the kernel or have android completely ignore this event or intent?
If I knew it was in the kernel source code (and where), I wouldn't mind learning how to cook a kernel myself to do it.
Thanks for any help.

I have this issue as well and have been trying to figure it out. Currently have something close for aosp roms, but going to take more time to figure out for sense. I have been looking into it.

nope we should start our own club. Busted ass usbport club. I looked into swaping the port out and soldering on a new one. But after I looked at this little tiny piece of hardware, I though a software edit will be easier. And it is you need some intense tools to pull off a good swap. its sooooo small.

Thanks, I figured it's a common problem but it would be nice to find a good solution.
I haven't seen too much of a connection with particular roms causing the issue. When it was originally a big problem a few months back (before it stopped happening for me), it would act the same way on every rom I stuck on it.
However, I just switched from deck's aosp rom to Synergy not long before this started happening again, and the sense roms definitely make it much more of an apparent problem than the AOSP roms would.
Physically to stop the problem, I know it's related to the MicroUSB port and I may try disassembling it if it gets bad enough.
From another post on it: "It's pin 4, not 5 , 5 is ground in the usb cable, when pin 4 is grounded it puts the unit in dock mode."
I'd post a link to the pinout, but the system makes me too newb to post pin outs. (Just google kineteka microusb b)

The same thing happened to my phone yesterday and it is pissing me off. Will it eventually go away over time or is it a permanent issue. Meaning when it dries off will everything be ok. I'm thinking about taking it in since I have insurance and see if they will either fix it or swap it out. I'm going to wait a couple of days to make sure there is no moisture in there.

There is an app called NoDock that you can download to fix this. In my experience, it does not work with MikG (which is probably a Sense 2.1 compatibiltiy issue). I am running Deck now too, and so far no issue with the AOSP ROM. If there is an issue, I read on the NoDock market page that CM based ROMs have an option to disable, and thus NoDock is not needed in this case.

Hmm. I'd think an app could be written that would catch the intent and do nothing, as well as manually adjust car dock volume via the volume controls. Maybe. But I don't think any kernel-level edits are needed. Maybe a decent dev can write something like that for you (I couldn't). [Edit: looks like NoDock might be that app] Another thought that might be stupid: have you taken a can of compressed air to your USB port?
Also, just a friendly reminder, there isn't any development work posted here so instead of the development subforum, this really belongs in General, or maybe Q&A. As a general rule, new threads in this section are only for sharing work you've done. Not to pretend I'm a mod or anything, just wanted to warn you so you don't get flamed to death next time.

In sense roms might be able to check AndroidManifests for either
http://developer.android.com/reference/android/content/Intent.html#CATEGORY_CAR_DOCK
or
http://developer.android.com/reference/android/content/Intent.html#CATEGORY_CAR_MODE
Then remove the intent from the application, so that nothing would happen.

I was definitely looking into this within the android.policy.jar but my developer knowledge is minimal compared to your expertise. I'm really hoping to not have to download any apps and I'm reluctant to go get an insurance claim until the new OTA has been rooted successfully. Anybody makes any move forward on this I would be glad to donate. This started happening to me when I was working out with my phone in an armband and some sweat most likely got into the charger port causing a short (my theory on what happened). If it is still going on by the time the OTA gets rooted, I'm going to go swap it out at the Sprint store.

I thought it was illegal to sell rooted phones period. Or is it only illegal to make extra profit just based on the fact that it is rooted. That isn't to say that someone will do it anyways. My brother, who is phone illiterate, just got a nexus s and I really like it. I heard that the GSM version will be the first phone to get ICS (ice cream sandwich) so that means the CDMA one will be next. I'm perfectly happy with my EVO except when dumb stuff like this happens. I hate myself for asking but you got any progress on the rooting of 4.24 and the newest Hboot. Has the source code for the new Hboot been released?

I had a similar problem however it was caused by me putting my phone in my car dock
I had to freeze/uninstall both car panel and dock mode for it to finally stop giving me a notification and blinking the screen on and off when I hit bumps

Had the USB issue on mine too.
Usb port is anchored down to circuit board in 4 places, those solder joints get
loose and the trouble begins.
I used a regular soldering iron to heat up the solder and bring the port back against the circuit board tight, no more car-mode.

The 4 points only hold the usb plug on to the board, on the backside of the plug, is where the actual connections are being made. They are almost like spring loaded connections.
When the soldered points get weak, the usb gets pulled pulled away from the mother board and some of the pins will not make contact.

Here is a kernel for CM7 removing dock accessory detection based on the latest CM7 kernel. If someone wants to build a version for Sense or based on another kernel, just unselect config_usb_accessory_detect and config_dock_accessory_detect support under USB Support > USB Gadget Support > Dock Accessory Detect in the kernel config before building.

This is crazy mine an my girls phones are doing this we bought a charger off of eBay an that's when it started I tried titanium pro an froze car mode seems to work but just a bandaid

Thanks man I'm going to wait for some dev to jump on this. Hopefully someone can create a .zip so you can flash it over any kernel. I would really just like the stock kernel with this option added in.

[Q] Oven QuickFix – Will it work for Nexus S?

Hello.
So it came. My Nexus S betrayed me. I started getting random "inabilities" to boot my phone. It was rather not booting than booting. The phone was booting like 1 out of 10 times (stuck at Google Logo). Suddenly I found out that applying pressure to the back of the phone (to the SIM card slot area) while pressing the power button solves the issue. At least temporarily.
The conclusion I came to is the following: Given this information (applying pressure) I came to the conclusion, that the soldered-on storage chip is not so soldered-on.
What about this: If oven-baking our laptops can repair them, is it possible to fix my Nexus as well? That is the question for you, guys! Will it take the heat? Can some components fall off the board when heated? Or get burn? If so, can I apply heat directly on that damn chip? That is the metaquestion!
Thanks in advance!

How can you fix a laptop by putting it in the oven dude ? Are you serious ? Ive never heard of that. Ever.
And i can't encourage you that this is a good idea cus it doesn't sound good.

I would rather use a proper heatgun and try to heat the place little bit while isolating rest of the "working" parts.
But honest advice, spare yourself the trouble of disasembling everything and start saving for new phone :/

Oven quickfix does indeed work. I once repaired a HP nx7000 by disassambling the NB and put the motherboard into the oven. Worked like a charm afterwards.

I found out that my coleague has a heatgun and his friend even has a machine for this (reballing stuff I would guess).
It is, however, good to know, that I'm not lost once I find out I'm out of RMA period. I *THINK* my phone does does have a valid warranty BUT I'm not quite sure I can find my papers and get to the store soon enough. It's indeed good to have a backup…

Go for the heatgun if possible. A lot of the parts on phone are extremely heat sensitive unlike larger hardware and you would likely end up damaging something else rather than just fixing the storage. Have put back to life quite a few devices using a heatgun and proper shielding, mainly xbox 360, video cards and other random peripherals.
Still would save for a new phone though, because it's likely it might die completely on you in the close future.

[Q] Killing O3D

Hi,
I've already loosed my patience for LG. Today I've sent phone 4 time for warranty, including one software problem.
I'll just want to kill a phone completely so they send me a new one.
The question is, how to do it right? May i run stability tests since CPU will fry? Maybe you have other solutions? Killing memory chip?
Regards,

1. rail + train -> already proven here
2. anvil + hammer -> still in experimental study

sound legitimate
Still i'm O3D owner since 07.2011 and we all know problems it have since release (GHOST CALLS). I'm really think about getting this thing killed and sending it to LG repair center for exchange to other phone. Not to mention that I received phone yesterday and today it was sent back to repair (LG technicians damaged volume rocker).
Any ideas how to make phone unusable and still have warranty?

Overclocking is out of questions since they check the update counter. Samsung ones are pretty obvious but LG is very good at hiding things.

Exactly. it's a standard protection practices, also common in PowerPC and x86 processors, which they trip at 80 to 100 Celsius - close to the boiling point of the water.

I already had a MB replaced month after purchase. I've was using CM7 then and internal memory just died, still I was able to go into recovery or flash a different rom.
Maybe I've stated it wrong, the phone need to be broken, so not exactly a MB or so. Maybe a charging output, mini-jack (just repaired 2 days ago), mic - whatever. It will be a 3 hardware repair, and then I'll be allowed to ask for new phone (Nexus maybe).

Easiest way is to pour water on it for 5-10 seconds turned on since there is electricity I dont know if it safe do it more I never tried it so im just guessing Then Just pull it out Dont dry it completly just wipe it little bit with towel and use it,dont turn it off. just use it phone parts should die if only screen dies then get to the motherboard and cut some cable lol. I dont know why Im helping you thats too brutal but it will work for sure

It may work, but who know if there's humidity sticker inside the phone, the water sensitive sticker's useless anyways. And the most likely worst scenario would be for the flash chip to erase itself.

I'm still waiting for the phone to back from service. Maybe i will just play with mini-jack again. Plugging headphones and moving jack inside should damage stick points, of course i'll make gentle moves. Or.... CM Flashlight set on maximum brightness can damage camera LED?
I just received answer form LG, any hardware repair is counted as significant one and will allow replacement of the phone (at least I'll be able to ask for that.

I spilled Ice tea over my phone today and im trying to save it but anyways here is little story that Im made me believe for water destroying chips When I was young I took my dog and hold it above my brothers electric piano and I wanted him to play lol. but My dog got scared a little bit so It did little pee on the keys. I turned it off and took it out if electricity and took something to dry it off but everything inside boiled anyway.

When you send it the gourth time in garantee you have the right to get a new phone or to get back your money. Iam from germany and for us it works like this, before i had for.my girlfriend an optimus 4x after 3 times of sending it in garanteen i wanted my money back, without problems i had my money back. Now i bought an note 2. Try to get your money back hope the best for you

That's it! I'll pee on my phone!
Still waiting for phone. I will probably start with moving headphones in mini-jack back and forth. Other than that, CM and "full power" flashlight.
On the other side I can just count on LG, maybe they send me a damaged phone as last time.
