I would like to build an Android car infotainment device to replace all my gadgets inside the car. One option would be a micro PC with USB touchscreen and a lot of devices connected via USB. The other one would be an Android gadget, either small tablet or TV box.

The biggest question I have is: what Android devices support 5.1 audio? This is a must, though I actually can use only 4 channels. What audio formats are supported for this?

The other question would be TMC - the FM kind, not online.

Are there any embedded platforms out there (except PC and Android) which support multi-channel audio?

Has anyone done this before? I might be reinventing the wheel.
[Connected Car] brainwash123:
No updates? Either nobody knows about Android 5.1 sound output or they are working under NDAs.
[Connected Car] kagedws6:
Are you planning on keeping a headunit to control volume, do you want am/fm radio, etc....

without a headunit you will need an amp where you can use the headphone to rca adapter and usually its the amp that would add front and rear to the left/right output of your android device so you would still get the 4 chan output effect. to go for the 5.1 chan you will need another device that actually controls the 5 speakers plus the subwoofer which might be tricky but I'm sure its not impossible.

the setup I was going to go with was a amp that I can mount its power controls (left right front back and volume) (or amp/eq combo) to where I can reach it and build a mount for a 7in (possibly diff size not sure depends on how it will look) and use the heaphone to rca adapter to power the audio and put the usb inside the dash possibly with a little hub if they make it (that way not only is it getting power from it, if it allows, the addition of say a thumb drive with added music/movies. some tablets/phones have fm radios built in as long as something is plugged into the headphone jack (my new phone doesn't seem to have it but thats a feature I will be looking for in a tablet)

4chan amp

eq that would allow 2 chan in and 4 chan out plus sub out (if you have a separate sub amp)
[Connected Car] brainwash123:
I just want to know if there are any android devices that are able to stream 5.1, I can take it from there. Same question about TMC support.

Some details:

My car is already fitted from the factory with 4 channel preamp and 12 speakers including subwoofer low-pass. It has low-level input for those channels, worst case I would buy a preamp.

FM is pretty much given on most Android devices, probably excluding some tablets, but I won't actually miss it if it's not there.

TMC would be nice since all Androids usually have a GPS sensor and sometimes compass.

Anyway, it was mostly a request for suggestions or even a rant - I'm surprised that something like this doesn't exist yet. With the exception of dedicated units going >$$$-$$$$, an alternative set-up would be a medium-range blueray player coupled with an Android tablet. Music control could be set up with DLNA, bluetooth streaming or mixing player and android audio would be a bit harder but not impossible.

Great Idea
[Connected Car] D@nielT:
Hi,

Currently I'm also thinking about installing an android tablet in my car to have music, navigation, movie player, speed camera warning, etc. But the biggest problem is the sound. I want to connect tablet with car audio using jack-jack cable. Everything is fine till the AUX source is selected in car audio device, but when I switch it to Tuner or CD - the sound from tablet is cutted off, so e.g. navigation announcement are not heard.

Any suggestions for this issue?
[Connected Car] zezinho7:
audio rom

its a shame that there are many many roms but none fur special purposes like this.

we need a car rom ;)
[Connected Car] Cris123:
Only solution can see is to run the audio from the tablet alone. I.e. use the tablet to provide both radio tuner AND navigation. You will end up using the car system purely as an amplifier.
[Connected Car] Brandon011795:
This would be what I would do in this situation. Or just unplug the audio cable from the tablet when using other radio options so the navigation will come through the tablet's speakers.
[Connected Car] unL33T:
I want to do something similar but rather than purchase a new device I want to use my Note2. No head unit at all. The Note2 would likely be dedicated to this use and I'd get a different phone to use as, well, a phone.

For sound I was hoping I could use USB OTG to connect a USB sound card with 5.1 output but I'm not sure if this would work. I want to use the sound card instead of audio direct out of the headphone jack because that reduces my connected cables to just one (easier) and should provide at least 4 channel output which eliminates the need for another device to control volume, fader, and balance.

For radio I was going to use SDR for AM/FM (and more) via a cheap USB TV tuner.

http://sdrtouch.com/

Where I'm stuck now is that I'd like to be able to connect an iProduct (iPhone/iPod) like you can to most car radios and control/stream music from the iProduct, via the Android Note2 using USB OTG again. I cannot find how to do this but the Parrot Asteroid Smart runs Android and it seems to be able to do it so it must be possible.

http://www.parrot.com/usa/products/asteroid-range/parrot-asteroid-smart/

Any info anyone can provide regarding the sound card and iPod integration would be highly appreciated.
[Connected Car] brainwash123:
You can go wireless and use some AirPlay receiver for Android.

I don't know about wired solutions, the classic iPod connector has ~30 pins and some of them are used for audio and some of them are used for serial-like playlist control plus current track information.
[Connected Car] unL33T:
It's just a USB to iPod cable that they use for everything else... Parrot Asteroid Smart that I linked to has it as do most modern stock head units.
[Connected Car] unL33T:
Did a little more googling and it seems several companies sell android head units that support iPod.
[Connected Car] k.s.deviate:
Why don't you use a USB DAC? There are a few out there that are surround sound capable.

Out from the DAC into an eq preamp and out to your existing amplifier. The eq preamp has main volume controls as well as sub control with dedicated output.

Also there are head units out there that are just "receivers" capable of accepting a digital inputs and outputting 5.1 signal via RCA.

I installed a nexus 7 2013 in my VW, currently using Bluetooth to connect to a receiver where it the outputs to an rca input on my deck that was relocated to my glovebox. I am planning on replacing the Bluetooth adaptor with a USB DAC in order to achieve a higher quality sound.

I am currently doing a similar install in a 2010 charger, a deck will not be used however as I will be using the DAC method with an eq and output to the factory amp. I considered going the android TV box route as I have a MINIX box, but there is some work involved in getting the touchscreen to function properly as it is not set up for this out of the box.

You can purchase a double din deck from eBay (I stumbled across it a few days ago but didn't write the link down) it has a dual os system. It uses android for the car audio function and windows for the car PC function. Not sure how well it works but it got reasonable reviews.

Edit: ...and once again I answer without reading the whole thread...:silly:
[Connected Car] unL33T:
Is it somehow easier to get all the various apps on the phone to output audio to a DAC than a USB sound card?
[Connected Car] k.s.deviate:
I believe when the device detects a DAC (must use an otg cable BTW) it automatically re routes all audio out the USB. You can disable automatic USB audio routing in developer settings.
[Connected Car] unL33T:
That sounds easier. Thanks for the tip.
[Connected Car] unL33T:
Well I can't find any information regarding the iPod integration and I've found next to nothing for DVD video and audio CD playback and radio and backup camera functionality would also take some mucking about so it looks like I'd probably be better off buying something like this:

http://www.ebay.com/itm/7-Android-4...621?pt=LH_DefaultDomain_0&hash=item2a31320af5

Which has it all sorted out already. So much for that fun idea. No idea what apps they use for all that stuff.
[Connected Car] brainwash123:
Which has it all sorted out already. So much for that fun idea. No idea what apps they use for all that stuff.[/QUOTE]

That unit looks slow at only dual-core. It will probably be sluggish when multi-tasking.

The main chip probably supports several I2S devices (aux in/adc, tuner/adc, DVD) and routing plus demuxing is done via linux hardware control.

The DVD player and tuner probably support the i2c or spi protocol to control seeking and other functions. This is again controllable via the linux devices.

Usually the consumer devices don't have these easily exposed and it's probably a non-trivial task to piggyback on existing hardware, assuming the needed connections are broken out on the board. As far as I can see the only Android devices with CD or DVD are the car players like above.

Another option would be to take the sound from the HDMI signal. A DVD player/tuner can be wired in parallel with an HDMI switcher. However controlling the tracks would not be easy, it would require emulating the remote with an IR transmitter.

Hi I'm new to the TF300TG.

As I am experinced on the HTC Desire Z/G2 there seem to be some differences..I think most people want to know anyway if their changes can be tracked by Asus in a case of warranty or not...

If I root the phone the bootloader is still locked, right?!! Is there away WITHOUT Asus knowing to unlock the bootloader up to now?

I am right now on stock will a factory reset remove the root(superuser) again so that the device would look like(at least) an untouched tablet?

Best and thanks in advance,

[Barnes & Noble Nook Tablet] wvhuckleberry:
I rooted my Nook Tablet in early January from the XDA site and following Albert Wertz video from that time frame--worked like a dream---HOWEVER, the system froze up the other day and i inadvertently set the darn thing back to it's original state---the problem i am having is when i go to the XDA site to root it (where the three links are), the usb debugging will not open up---it is the one for the tgps launcher---I am new to the forums and this site will not let me post the link that goes with it

I have tried over and over and on the nook and two other computers--I have tried to search it on google and such and everthing takes me back to the same XDA site

I know there is now an SD card available but I really like the OLD way---i just feel comfortable with it

I sent an e-mail to XDA regarding what i thought was a bad link but they said it was not their area and to look for help in a forum---perhaps they misunderstood me or they were correct

Can ANYONE help me re-root my Nook Tablet using this method with a good link---thanks so much

[Samsung Galaxy Nexus] wyzergrafe:
I was sitting here with my galaxy nexus and wondered if there is a widget of some kind that clears out the recent tab?

Does anyone one know where, or could anyone make one?
[Samsung Galaxy Nexus] martonikaj:
Recent tab of what?
[Samsung Galaxy Nexus] wyzergrafe:
Not recent tab, but when you press the recent apps key, if there is a app to remove all the apps you just been in instead of removing one and one app..
[Samsung Galaxy Nexus] martonikaj:
Why would you want to do that?
[Samsung Galaxy Nexus] 3ddyz:
You mean a task killer...?
[Samsung Galaxy Nexus] dschreiber69:
I do not think that swiping away apps from the recent tray is the same thing as killing them.
[Samsung Galaxy Nexus] RoadHazard:
Nope, swiping an app away from there doesn't kill anything, all it does is remove it from the list. It's a "recent apps" list, not a "running apps" list.
[Samsung Galaxy Nexus] AshtonTS:
It does kill the app tho. I have an app that has a sticky notification thats always there when the app is active and it goes away when i swipe it away. It went away when I used the HTC task killer or Advanced task killer on my Rezound and Incredible, but on the Nex, that kills it
[Samsung Galaxy Nexus] martonikaj:
It doesn't really kill the task in the way that you think. It'll kill the foreground process and load things into RAM, but it won't always necessarily just stop it in it's tracks.

Perhaps you should have bothered to read that this is the SGH-I777 forum before flashing, not the SGH-I727 forum? Flashing anything meant for I777 on I727 will kill the bootloaders and hardbrick the device. JTAG time for you - mobiletechvideos.com can probably help you.

I am running darkside v8 with darkside kernel #5. I have beats audio mod installed and awesome beats mod installed. I can call somebody and the call goes through. For what ever reason when somebody calls me i can't hear or say anything. Wi fi calling is off. I have cleared caches, i superwiped before i installed the rom and i need help. Attached are a few of the logcats i have created. The latest one is 2012-07-15-15-31-05. The others were created when i was on v7 darkside. The radio is clearly not the issue either, i have tried the lc8, le1, and the blaze 4g radio. All have the same problem. I have also tried changing the dialer but that doesn't help either. Although on v7 the phone.apk would crash and my calls wouldn't go through. That is fixed in v8. Also even without the beats mods i still have the issue
