Sorry, I don't, but I take it you're not using an external/USB DAC?

I'd highly recommend one. Night vs day difference (compared with Nexus´ onboard sound)
[Nexus 7 Android Development] Walz83:
Can you provide details on what you had to do to get it to work, including carcam settings you used?
[Nexus 7 Android Development] gregthomas129:
No I have a UCA202 dac, but I'd like to have a higher output from the tablet so I can turn the gain down on my amps. I'm fighting some noise which is related to my amp install and not the tablet. Basically the amps are boosting the noise as well as the audio. So if the tablet output is higher, amp gain is lower and noise is lower.
[Nexus 7 Android Development] Iceman_jkh:
That's a good start! I'm not sure what the output voltage is, but my Sabre DAC outputs up to 2v (at full output).

You could try shortening the distance/wiring between the DAC and the amps (by using a USB cable to place the DAC near the amp), as this may reduce your induced noise enough to boost your amps' gain.

Otherwise, it might need to be a new DAC or look at your wiring layout.

I don't boost the Nexus above 85% volume in my car or I'd go deaf.

Amp gains are about 60%. No perceptable noise. Car and speaker pods are fully sound deadened btw.
[Nexus 7 Android Development] redeyedjedi:
The only sure-fire way to get more output from audio is to use xbmc and boost it db. It absolutely works although xbmc isnt the most convenient audio player.

So i guess b0bd should be very upset with you....since you COPIED his entire grabfocus app....added in ONE function, changed the name and called it YOURS?? Google and cyanogenmod should be mad too......you took their code, made small changes and renamed it. You are a software thief. Nowhere in your pwrevntmgr app does it say that you copied code from b0bd and that HE is the original coder. If i fork his grabfocus app and make my own power event mgr are you going to ask why MY xml files look so similar???

Anybody who gave you a penny before downloading a rom is an idiot who should use apple.

Kang-ing is cool. Kanging is legit. Kang-ing is how android gets better. Kang-ing is the ONLY reason for github.com and bitbucket.org to exist.

i named my kernel so as to imply that its other peoples works. YOU need a lesson in the GPL. Then you would understand why we are not the ones breaking the law.
[Nexus 7 Android Development] Kookie_Monster:
Again... as in Jack Norris's case... later today I'll post a screenshot to prove you're quite mistaken.

http://www.urbandictionary.com/define.php?term=Kang

Makes no sense continuing to discuss this. You've made your point very clear.

This discussion really makes no sense. I'm not here to stand up for Timur (he doesn't need me to anyway), but I can actually understand why he might feel offended in any way. You guys already admitted to have used his ideas and some of his code anyway and he admitted that the codes are not identical. Makes no sense keeping this up...

How long should it take for this to boot after initial flash? I've been at the flashing "SlimKat" screen for a few minutes now.

EDIT-Anything special I need to do to install this ROM? Do I need to do that file convert thingy?
[Nexus 7 Android Development] michiil:
Thats to long smething went wrong .

Wipe ad reflash (:
[Nexus 7 Android Development] mfenske:
Got the ROM working. Now I just need to figure out the OTG stuff.
[Nexus 7 Android Development] pablomaes:
While the device is indicated as stk1160, carcam detects it as UTV007.

Nothing special..just connect everything.. and configure carcam correctly in my case.. select UTV007 chipset and NTSC cam model.

One question.. I don't know if i'm doing something wrong.. but when the system goes to sleep after unplug the power source.. when i plug it again before it enters in sleep mode (or screen goes off).. the shut down process is not interrupted, as it should be. Maybe is something about a wrong configuration ¿?
[Nexus 7 Android Development] dn*:
Hi guys.

I think I'm being a bit dense but I'm having some trouble getting started.

I was looking for an alternative to timur's ROM as it uses an old android version and found this ROM.

From what I gather it is a full ROM, not something I flash over the top of another ROM. As such, I downloaded the zip to my device, factory wiped it, wiped cache and dalvik, and flashed the zip. The first thing I noticed was that it only took a manner of seconds. I'm used to ROMs copying files and taking at least a minute or so.

When I reboot, it's 4.4.4 with the Kangaroo kernal, but the ROM looks complete stock. I can't see how to change anything in Kangaroo, though more importantly, I can't see how to change stuff like fixed installation mode.

I plugged in my USB Y OTG cable and fed my USB DAC (one of these '3d sound usb' ebay jobs http://www.ebay.co.uk/itm/USB-2-0-t...uterComponents_SoundCards&hash=item1e79af791b) and power. It didn't 'hotplug', and I reboot and it still isn't the main device.

Maybe it's incompatible, or maybe I've misunderstood the installation of this ROM, but clearly I'm having some trouble. Stuff like the nav bar etc. I'm clueless how to enable.

Cheers
[Nexus 7 Android Development] Walz83:
First up you need a OTG y-splitter cable (looks like this http://topproduct.home.pl/userdata/gfx/ed4ec8a83c0a01e9b38e31741ba373c3.jpg)

This allows you connect USB devices (e.g. flash drive or USB hub to connect multiple devices) and charge the N7 at the same time.

---------- Post added at 09:10 AM ---------- Previous post was at 09:05 AM ----------

The ROM is based on SlimKat so you should see notable difference from stock. You should also see SlimKat boot animation.

I flashed my N7 normally like I flash any other ROM. Just try again. Make sure you are using the right ROM Grouper or Tilapia.
[Nexus 7 Android Development] dn*:
Thanks, I have a Wifi tablet so Grouper is the one right? The ROM boots fine and everything it just looks..plain.. and I can't see anything to do fixed installation modes?
[Nexus 7 Android Development] Walz83:
Yes Grouper is for WiFi.

The fixed installation mode is part of the Power Event Manager settings. Look in Settings. You can also access it via the Power Event Manager icon in the notifications bar (icon looks like a battery with power plug).
[Nexus 7 Android Development] machmanx:
no license?

I'm just curious why T1mur didn't release his code under a license, or did he? That's like throwing $100 bucks on the ground with a fish line attached to it. Why release your code if not for the purpose of someone else to use it or make it better? There's no point otherwise.

In the first place YOU'RE the one who released your code to the public view. If you didn't want others using it, then DON'T RELEASE IT! But even without your code, one of us would've done this project sooner or later. You're not the only smart cookie in the cookie jar. God knows how much I've wanted this sort of thing to happen and I am currently improving my Java skills. Android programming will be the next on my agenda. As far as ideas goes, take a GOOOD LOOK at the world around you: EVERYTHING IS PERMITTED...wait I mean companies copy off of each other ALL THE TIME! Microsoft and Apple are prime examples. So yeah, without your code we would've done this on our own. Well, it's not like you did anything on your own anyway :rolleyes: .

What is it that you're not happy about and what can we do to make it better? You don't just rise from the dead without some kind of motive. :rolleyes: I mean DAMN it's been soo long that we didn't know if you were still alive or not. If michili and redeyejedi say that they attempted to contact you, then I believe them. Either tell us what you want so we can fix it, or stop complaining because it's already been done. And don't start talking about feelings. The milk has already been spilt and no one here wants to hear about feelings. We don't do psychiatry here. Now out with the truth.
[Nexus 7 Android Development] Walz83:
Have you tried connecting a video RCA output from something like a dvd player or gaming console? Do you know if it would work?

I don't have the no interruption issue, and i just connected everything normally. I did have an issue with power event manager not working at all because i hadn't given it superuser access. Maybe double check that.

I have just mounted my nexus 7 2012 on my car...

this Kernel (Kangaroo Kernel) is what I have need, but I have some questions, if anyone can help me:

1- Are there some alternative to this kernel? This project seems dead, and with new Android L (released soon) I would like upgrade. What I need it's only OTG+Charging

2- Power Event Manager: where can i find last release? And more important, where can I find some description for app options? I don't know the difference to use Tasker

3- Anyone know how can "merge/expand" usb key and internal memory of Nexus 7, something like UnionFS or Aufs

I know are a lot of questions, sorry.

And thanks in advance!
[Nexus 7 Android Development] machmanx:
Dac and navbar + others

Yeah I checked my Kernel in the "About Tablet" option in settings and it does say that it's the kangaroo kernel, but it also says michil@michil which tells me that this is a different version from the original kangaroo kernel.

As far as USB DAC goes not all of them will work in native mode (I don't even know if yours is a DAC or not cause it could be a simple Windows audio device). The audio implementation is a user level thing and not an Android implementation. So you shouldn't expect whatever to work on it. You could however use it in non-native mode through a program called "USB Audio tester ROOT" to test to see if you're device is working through OTA (I thought USB Audio Player was free but looks like they only offer the PRO version...would've been the music player test). Now this program will allow your USB device to work through the program ONLY, so it doesn't fix anything. If your device works through the program then we can confirm that your USB OTG is working and that it's simply what I said above: The audio device doesn't support native audio implementation. At this point you should chuck that audio device against a brick wall :D and invest in a proper USB DAC. Many users here recommend the Behringer UCA202 (BUT only the audio output is natively supported; the inputs are only supported through a dedicated program). I use the HiFiMeDIY Sabre U2, which is compact and the USB interface doesn't bottleneck the audio conversion rate (you don't have to care about that part). The Behringer works fine and that's all that matters to most ppl.

The navbar options are located in settings -> Navigation -> Navigation Bar -> Buttons. What kind of layout you want is up to you.

1- The project isn't dead as the devs are clearly replying to posts. People are obsessed with updates when they don't really need them. I mean is your monitor firmware updated every week? No, because it works. If there are any issues with the ROM or kernel then it will be fixed and updated when necessary, but there's no need to constantly update a kernel that has nothing wrong with it. As for Android L, PATIENCE! Wait till it comes out for a while and then we can tell if this needs to be updated or not. As for OTG + Charging, this ROM already supports it. If you want an alternative option then read through every first post of each kernel thread for the Nexus 7 and you might come across it. I just never needed to since this one does the job.

2- This ROM contains the latest version of Power Event Manager. I don't know if releasing a stand-alone ROM would even work because of some of the customized options that work on the Kangaroo Kernel only. The things the devs do aren't standard: they are implementing things that are outside the realm of Android support. So you can bet that finding support elsewhere for such functionality is gonna be a pain, though you might find it. These guys just make it easy for us ;) (Thanks michili, redeyejedi, and crue and all others who made this possible).

Can't help you with option 3.
[Nexus 7 Android Development] kam1kazze:
Thanks machmanx, you are very kindly!

...and sorry, When I spoke about "dead" I was referring to the kernel, I had copy&past my original post in http://xdaforums.com/showpost.php?p=55817987&postcount=651.

You have perfectly described me when say "People are obsessed with updates when they don't really need them"..I think it's a psychiatric disorders :eek:

But now, I have more questions :D

Now I have Official CM Rom with the Kang-aroo V2.0 kernel. What are the advantage with your ROM?

I don't know quite well what PowerMangerEvent do better of tasker. For what I understand the only thing that I can do better is Firm sleep, and lock USB disk. But for keeping screen on I always use tasker+SecureSettings.

My external USB disk is "unexpected disconnect" when power ac go away. For avoid this should I insert an power (constantly) hub? And if answer is yes, what is meaning of lock USB disk?

For my old third questions, there is something you can do: add unionfs.ko to the kernel. If this is not possible, do you can explain how to manage internal and external memory of your N7? two separated folders? I think can be quite useful merge/union/expand all memory (external and internal) like Linux LVM with UnionFS. With this features if you have: 16GB (internal memory) + 2x32GB (USB KEY) you can have a single mount point of 80GB. And work like a virtual FS, under you can use what you want.

Always sorry for my a lot of question, I hope I don't waste your time. Thanks!

For anyone like me, I answer myself to the PowerMangerEvent Settings:

Lock screen in fixed installation mode: I think switch off screen on power less

Skip countdown screen: self-explanatory

Fixed installation mode: In FI-mode, your tablet will go to deep sleep, when the external power supply is interrupted. Your tablet will stay in suspend mode and will immediately wake up, when external power returns

Fas charge in host mode: up to 1400 mAh in charging

Firm sleep: allows you to disable all wake-up alarms while your tablet is in deep sleep mode

Lock USB disk: will keep your /storage/usbdisk virtually mounted through power loss situations
[Nexus 7 Android Development] machmanx:
So most of the questions you are asking are outside my expertise because I don't mount an external drive to mine...the internal memory is plenty for my needs, for now. All I can tell you about the Power event manager is my personal experience and it's about battery life. Because of its deep sleep mode when my key is turned to the off position, the battery will last for A LONG TIME! There was this one time I didn't drive my car for 5 days because I was driving my SUV and when I came to my car again the tablet battery was at FULL! (I imagine that even though the ignition key was off, there was a tiny bit of charge <100mA getting through the switched wire) Another time when I took my tablet out of my car and it was already in deep sleep mode and I didn't use it at all for 3 days, my battery life was at 91%! I mean that deep sleep mode is srsly battery saving! I don't know if this is achievable with other ROMs or Kernels but this has surpassed my expectations...hell, I wasn't expecting it to do that. So the thought that I could leave my car off for an extended period of time and my tablet won't be the first thing to breakdown is a relief. Most car mods ADD maintenance/extra care time required by the owner to the vehicle. The tablet car device doesn't. That alone makes it a worthwhile project and well I'm getting a bit off topic here.

So yeah, the tablet has a limited amount of battery charge. But the deep sleep extends that charge to crazy amounts so that when you enter your vehicle after a long time it still works! And this ROM is one that can do exactly that. Also this ROM has the extended navigation bar, which is a non-Android feature because they stripped it out of the new versions of Android. These guys brought it back for us. And of course the other stuff like tuners, cameras, storage etc. which make this a complete package. Otherwise you have to go hunting on your own to find each individual component, if that's even possible to find them all, and figure out how to install them yourself with barely any support from us. Hence why I bought the Nexus 7: TONS OF SUPPORT!

Easycap and Carcam

I cannot for the life of me get carcam to work. I have both an EM2860 and SMI2021 Easycap but I can't get any video to show in Carcam. I have verified it's getting a good video signal by connecting the video wire from my camera to my TV and getting a picture.

I installed both carcam 1.3 and 1.4bbb and I tried a combination of all their settings and got nothing. I was under the impression this was plug and play, is there something I'm missing, an extra step I have to do?
[Nexus 7 Android Development] michiil:
Proberly no. None of the devs have a 2013 nexus 7.

But if someone wants to port it over the source in linked in the op (:
[Nexus 7 Android Development] Walz83:
I haven't installed my Easycap yet but reading through this forum it appears that once you connect it all up you should see a file videoX in /dev (X could be any number i.e. video1 or video 2). You then input the X number in carcam settings.
[Nexus 7 Android Development] aameghoo:
When I had everything hooked up I recall not seeing a file videoX in /dev. I'll try again to double check. Any ideas why I might not be getting that videoX file?

Update:

So I double checked and I have no folder or file called videoX in /dev when I have everything hooked up how it should be. I'm guessing if I can figure out why this is I can probably get it working but I am at a lost as to what to do next

i'm coming from Timur's to try this out and having some issues... Is there a recovery that works better for installing over another? Clockwork or twrp? for example i could never get timur to work with clockwork, could only use twrp. First time i flashed this slimkat one, after the splash screen i keep getting a popup saying the Google process failed (process.google. something), i tried again and now it's stuck in a boot loop. I've tried a couple times with Clockwork and both it gave me the failed process and i tried a couple with twrp and i'm getting boot loops
[Nexus 7 Android Development] Walz83:

every time i hit ok, it keeps coming up. i tried flashing again and same thing. anyone have this?
[Nexus 7 Android Development] michiil:
Recovery shouldnt matter. It soumds more like you didnt do a clean flash.

Try to do a factory reset in the recovery (wipe data, cache) anf flash again.
[Nexus 7 Android Development] papinist:
Are you using an usb extension cable? In my first attempt, I used a poor extension cable and nothing works, I have no videoX file. Removed that extension and everything worked. I also tried with another extension cable (a better one) and it works.

I think it's not the purpose of this rom. When it is in deep sleep mode (as to preserve battery) the rom disables all wakelocks. To have tap-to-wake works, you should have some process checking continuosly the touch screen to intercept tap, and this will sure use some power...
[Nexus 7 Android Development] kam1kazze:
thanks machmanx you are always kindly :o

Anyone else can help me with the others question:

My external USB disk is "unexpected disconnect" when power ac go away. For avoid this should I insert an power (constantly) hub? And if answer is yes, what is meaning of lock USB disk?

Can I put n7 in deep sleep with Tasker+Kangaroo Kernel? And obviously wake up...
[Nexus 7 Android Development] ryanjv:
i was doing all three, factory, reset, wipe data, dalvik.. it finally worked (6th times the charm i guess)

I haven't had a chance to poke through all the settings but from the bit of time I've had to look around, there's a few questions i have. Sorry in advance if everything is being compared to Timur's, I've been using it for over a year now so I've gotten used to the feel, but i wanted to give this a try since there's a few little issues that I've been dealing with here and there that i'm stuck with since dev stopped.

-is there any way to get tablet UI? i don't' care for the wasted space of 2 bars, plus it throws off my icons and wallpaper alignment

-is there a certain process for getting FI to stick? such as turn on, restart then plug in or something? when my tablet is plugged in and the car's on, i can toggle to FI mode and nothing happens... when i shut the vehicle off, nothing happens and when i go back into the settings, FI is back to off and then when i replug in or turn the car back on, FI stays off

-Is there a way to see all the devices that are connected via USB like in Timurs? My OTG Y-cable goes into a hub which has a

-16 GB flash drive

-UCA222 to my Amp

-JoyCon controller.

My want of it kind of ties into the last point. It was handy that on start up if something wasn't responding properly, i could see that it was connected. Because at this point, i'm not sure if my devices aren't all found because FI isn't sticking or for some other reason. Right now, my flash drive is found and i can play music, but it won't come out my speakers, it's playing out the tablet and as far as my joycon goes, only my volume and seek buttons work, the other buttons i mapped aren't working. My mappings that i had while on Timur's

Vol Up - volume up

Vol Down - volume down

Seek Up - seek up

Seek Back - seek down

Source - short press - home/voice command(if already on home page) - long press - power button to turn screen off while driving

Mute - short press - back - long press - mute

having the home, power and back were very handy to have at your wheel while driving to reduce presses on screen as well as looking at the screen.

Did anyone else running a joycon have any issues getting it working on this rom?

Outside of these, it's clean and smooth and i love the customizable nav bar.
[Nexus 7 Android Development] michiil:
1. no tablet ui was disabled by google with android 4.4

2. you dont have root its disabled by default. Please read the op before posting. You will also find how to activate root in the op.

3. there are apps in the playstore aviable to do this. Its not included in this rom.

4. i dont know if google changed the keymaps for kitkat. You need to try. You could also try external keyboard helper to map your buttons.
[Nexus 7 Android Development] ryanjv:
1. I read that it was disabled, i just wasn't sure if there was some work around avaiable or some kind of app that could give the same look.

2. I do have root, and i did read the first post. while your post does say how to get root back, it doesn't at all mention details regarding FI, which is why i asked

3. Thanks, i'll look around. Any suggestions on ones that play nice with this rom?

Thanks for the quick responses
