[Nexus 7 Android Development] crzycrkr:
I'm honestly not too comfortable with soldering. Maybe I'll just pull the dock apart and give the epoxy a shot. I could always take it off if necessary
[Nexus 7 Android Development] patti_9000:
hey guys,

i can't find autodroid for nexus 7 2013!? Can i use this one on my device? (I don't think so..)
[Nexus 7 Android Development] Walz83:
Why do you need install_qv4l2_easycap_nexus7.zip?? The modules are already included in Autodroid.

What functions are possible with usb to can? Would you be willing to share your app?
[Nexus 7 Android Development] dashu42332:
GPS with car antenna

Can pleases give some more info(image or drawing) about GPS antenna .Because after installation N7 to car ,GPS lock is very long or even sometime none.I am suspecting GPS antenna is not clearly to sky to get locked.Can also mention any other tweak you made for GPS in hardware(antenna)and software(apps)...

Another issue i had is the USB mount.

When ever i load the USB disk with mp3 into n7. It take 1-2mins to get recognize in Apollo player.And even if i don't remove USB DISK after mount.Every power cycle of the car ,it same time recognize in apollo or Googleplayer.i try with smaller size usb disk like 4GB and 8GB,its the same story.But if i put mp3 in the internal memory of N7.It work perfectly without any issue...Do you guys have face this problem?
[Nexus 7 Android Development] MasterOran:
Nice Work.

But ive got a question to the PPl which use the rom , did you ever tryed to use a external(BT?) Mic to make the Google Voice Control doing its work?
[Nexus 7 Android Development] J.Edwards(not the killer):
hmm i dont know if they were included already, maybe this was just left from timurs usbrom.

The usb to CAN allows you to read all messages on your vehicle CAN bus, especially the steering wheel buttons. I dont have to fiddle around to adjust volume or go to the next track, i can simply use the original buttons on the steering wheel. Also carcam is started when reverse gear CAN message is detected. Im also thinking about a fuel efficency app because the fuel consumption you can read from CAN is not faked unlike the consumption you see in the instrument cluster

Unfortunately i cannot share the app because its too specific for my car and all the running apps (and messy) but i can tell you its not much more than the usb code which you can get here https://github.com/ksksue/PhysicaloidLibrary

my car has a GPS antenna on its roof, so i simply attached the GPS pins on the back of the nexus to the antenna. The backcover has a sticker with "GPS" on it, from there you see which pins they are.

I took the 32GB nexus so i dont have a usb stick, i had the same issue with the stick and i dont know how to solve it :(

I know there is a special apollo player which keeps the stick mounted, maybe this helps

no
[Nexus 7 Android Development] Walz83:
What are the chances you also have a Mitsubishi CJ Lancer lol
[Nexus 7 Android Development] superrama:
no matter what i do, i cannot get fixed install mode to work. I have the kangaroo kernel, i have root turned on, power management app have su persmission and fixed install mode turned on. my nexus will not sleep or wake with external power. am i missing a setting somewhere? do i have to use a specific launcher?
[Nexus 7 Android Development] joneidy:
Make sure that SuperSU request is not being denied for power manager app. It should work as long as root is not denied and you are using an OTG Y cable.
[Nexus 7 Android Development] Tengis:
I cannot get this rom to work coming from a Lollipop rom. I have done a full wipe multiple times and it always sits at a blank screen after the Google logo.
[Nexus 7 Android Development] Deeco7:
Any plans of a Lollipop version?
[Nexus 7 Android Development] MasterOran:
I really like to see a Lollipop Version as well.
[Nexus 7 Android Development] Tengis:
Ive never had so much damn trouble installing a rom -_-. I got the rom to install and boot up but every time it asks me for a password to decrypt storage.

---------- Post added at 10:32 PM ---------- Previous post was at 09:37 PM ----------

Finally got it working. Not sure what I did to get it working this time though.

Issue now is that I cant get OTG + charging to work. Sigh.
[Nexus 7 Android Development] Beakfire:
make sure you still have root, if you formatted the system partition then you'll have to flash the binary again, just grab the one from chainfire for the nexus 7

[Nexus 7 Android Development] Nsx93:
Need some help.

Got my Y OTG cable from amazon. Tablet will charge and powermngt will go into deep sleep and wake perfectly. BUT... I will NOT read otg USB media.

USB media will read IF I turn OFF Fixed Install in pwrevntmngnt... But charging will stop working. Its either one or the other.

Anyone have a solution?
[Nexus 7 Android Development] Mestapholes:
Does your Y cable provide power to the storage side too? Maybe it only delivers power to the tablet and you need an active hub behind that cable?
[Nexus 7 Android Development] tikicult:
Is anyone else

currently

having the following issues? I saw other posts in the thread about similar problems, but never any solutions.

1. Occasionally, the tablet will not turn on after starting the car. This seems to happen about every 4-5 starts. Sometimes I have no problems, and then just randomly, the tablet won't come on. I have to pull out a piece of the dash and physically power cycle the tablet to fix this. The power manager seems to work fine 80% of the time: power is cut, countdown, sleep, power on, tablet immediately on.

2. Another issue I have is that occasionally, I'll wake up to a dead battery. I used a battery app to try to track usage, but the only thing it tells me is that by largest power user is Android System. I think I need to find a better app to analyze and track down the culprit in this case.
[Nexus 7 Android Development] Nsx93:
Yes, only if I turn off Fixed Install then the storage side get power and read. But in turn the tablet will not charge.
[Nexus 7 Android Development] Mestapholes:
I only had this problem after I installed an app that tried to connect to a bluetooth device. After uninstalling that app, powerloss is really really low.

Can`t recommend a poweranalyser tool. I was able to guess a problem with that app directly and didn`t need to search.

You should really try an active hub. I would suggest that you search for one that is able to take 12V as power input. That way you can attach it directly to a switchable powersupply of the car. They are cheap, so not a lot to loose if thats not the problem (and you want a hub anyway, since you very likely want to add more than one usb component to the tablet)
[Nexus 7 Android Development] Mherder:
So i just tried to flash this onto my nexus 7 2012 and i'm stuck on the boot screen... i was previously on timur's rom and i wiped and installed this. any ideas? It just sits on the boot logo forever.
[Nexus 7 Android Development] Nsx93:
That's what happened to me the first time I flash this ROM. After I convert the system to run on F2FS it flash fine with the special TWRP. I also was running on slimkat ROM 4.4.4.

No problem then. First boot up will take up to 5mins but after tgat, its fine.
[Nexus 7 Android Development] Mherder:
I got it to work now but another problem. how do you disable the lock screen? It always wakes up to it and i can't find an option anywhere.
[Nexus 7 Android Development] Nsx93:
The only reason I didn't want an active hub is because I don't really need it. Since I only use the tablet for music and map. So I thought the otg y cable with one USB will work fine if I ever want to just watch movie on the micro SD during travel.

Was using it over the weekend and it doesn't charge very fast. I was only playing music but charging was pretty slow. Any idea?
[Nexus 7 Android Development] Mherder:
So i put the tablet back into my car, i like this ROM more than TImur's USB rom for sure.

Only problems

- Lock screen can't be disabled?

- Backup cam dosen't work (didn't work in timur's either)

EDT" Found the menu to disable lock screen, still can't do backup cam :(

Has anyone succesfully gotten a back up cam to work? I have tried 4 different capture cards and so many different apps. Nothing works....

If anyone has gotten it working can you please list the capture device you bought along with which app works on it?
[Nexus 7 Android Development] eaponte23:
Tried Kangaroo Kernel version 1.2? I know a few things didn't work right out the box when I flashed this ROM. Flashed Kangaroo and everything worked.
[Nexus 7 Android Development] Mherder:
No i didn't try that... do you have a link?

And do you have the backup cam working?

It says on page 1 that kangarroo kernel is built in, so shouldn't it already be installed?
[Nexus 7 Android Development] michiil:
I dont know does this work on ther roms? If so i will look into it when i get home (:
[Nexus 7 Android Development] Iceman_jkh:
It sure does ?

Timur's ROM is one example that could do this.

Thanks.
[Nexus 7 Android Development] michiil:
Okay i found something i will try it out later (:

EDIT: im sorry to disapoint you but i cant find any open source rom (timur never pushed his full sources) whitch supports this feature.. so i dont know where i schuld look for the code..

then, there are all the dvb/easycap modules with my kernel, or I can show you how to easily build them with oxydo kernel.

---------- Post added at 11:39 AM ---------- Previous post was at 11:26 AM ----------

yea, there are other roms that support it, from people who do support open source, but i never got it working because I couldn't find a good set of commits to guide me either. I want this too..... and those media buttons on the navbar, yea I want that!! I will gladly help....

The guy that you got the volume buttons from has tons of cool ****. I want to kang all of it... use a usb wifi adapter for android wifi...usb tethering...neat icons....usb bluetooth and 3g support.

well you have contributer rights on the device repo (: and i am already building with your kernel didnt you test my last release? even f2fs i working (:

i think i am going to do the media keys today thats not much work (: i just spent hours lookng into the usb tethering auto enable thing but i cant find anything usefull.. but usb tethering works if you enable it manually on your phone.

will definatly look into this (:

New build uploading (;

Changelog in second post.

[Nexus 7 Android Development] redeyedjedi:
So....if you enable USB tethering on ur phone and plug into your tablet via otg, then the internet works on your tablet? That's it then....its done. I figured slimkat already had it. Or do you mean something else?

The other thing is to integrate blue DUN/ blue VPN so you can tether via Bluetooth....I haven't fully figured this out either.
[Nexus 7 Android Development] michiil:
Yes i have tried that and it works . all i did was merge the one commit from your device repo regarding tethering but i dont think this has something to do with this.. so yea i guess it was already there (:

I havent tried bluetooth tethering but i think it should work out of the box but its pretty damn slow.

But you can always make a wifi hotspot (:
[Nexus 7 Android Development] gregthomas129:
I strictly use bluetooth tethering and it works fine.
[Nexus 7 Android Development] michiil:

[Nexus 7 Android Development] redeyedjedi:
easycap support is done. you will have to re-sync kernel tho, as I had to put back the older working drivers.

The newer ones dont want to cooperate because they need videodev...but an older version of videodev has to be built into the kernel so that the nexus 7 camera will work...very frustrated that I cannot seem to get these backported.....but for now the older ones are fine. we need YADIF!! There are tons of guides for cross compiling FFMPEG so I think Ill try that, since I failed so horribly at the new drivers.
[Nexus 7 Android Development] Iceman_jkh:
Thanks for looking into the USB tethering :)

I haven't had a chance to check, but it sounds like it's working already.

Is there any way of making the phone (Samsung galaxy S3 in my case), automatically turn on USB tethering on its side of things, when connected via USB to the Nexus 7?

I realise this would probably require both the Nexus and S3 to have some code/file/service/app installed on (both of) them. Any suggestions welcome :)

I have successfully used Tasker + Secure Settings to turn USB Tethering ON (on my S3), but I don't want that to occur every time USB is plugged in. Sometimes I plug my S3 into the PC, and I don't want Tethering on in that situation. I only want it on when connected to my Nexus 7.

Don't suppose anyone has any ideas how the S3 can be made to detect the Nexus (versus other USB plug ins).
[Nexus 7 Android Development] redeyedjedi:
You would need a Tasker plugin that detected a specific PID.... not sure if they have that. Maybe use a widget toggle on the phone desktop
[Nexus 7 Android Development] gregthomas129:
Get an app called Bluetooth Auto Connect for the tablet and Bluetooth Auto Tether for your phone. Both are use able as plug ins in Tasker. NOTE!!!!!!! The dev is called refluxa, there are others with similar names but you want the app from this dev.
[Nexus 7 Android Development] michiil:
i have to look into usb terhering more.. it sometimes is working and sometimes isnt..

i am doing a new build with easycap support now (thanks [MENTION=4035939]redeyedjedi[/MENTION]) will upload shortly (:
[Nexus 7 Android Development] gregthomas129:
I do have one issue to report... although I've seen it when using other ROMs on the Nexus 7, for the last 2 days I keep getting the "sleep of death" issue as they call it. I'll shut my car off and when I restart it, the tablet screen doesn't come on. It appears to still function, but the screen is off and won't even come on if I push the power button. I have to hold the button till it restarts. While the screen is off, I still get notifications so that's why I say its just the screen that stops functioning.
[Nexus 7 Android Development] michiil:
hmm have you played with the kernel settings? like undervolting?
[Nexus 7 Android Development] gregthomas129:
Nope, should I?
[Nexus 7 Android Development] michiil:
no but that would be an explenation..

are you using _crue_s powermangemant app?

afaik bsod's are typically kernel caused.. maby [MENTION=4035939]redeyedjedi[/MENTION] is able to help you (:
[Nexus 7 Android Development] gregthomas129:
Ahh I see. I didn't have the problem until this last build, What would you need from me to figure it out? I don't think I can do a logcat with the screen off can I?
[Nexus 7 Android Development] Nsx93:
When you say "everything works" do you mean the tablet will be able to charge and read USB storage at the same time?

Check to see if the Kangaroo kernel installed. I've had to install it myself since it never took every time I've flashed this ROM.

Check Settings/About Tablet... Good luck
[Nexus 7 Android Development] Mherder:
ok ill try. do i just flash this right over the current rom?
[Nexus 7 Android Development] eaponte23:
Yep, that's exactly what worked for me. Power event manager also worked. Had issues with this ROM waking once I turned ignition to the on position. Kangaroo fixed that aswell.

---------- Post added at 10:35 PM ---------- Previous post was at 10:33 PM ----------

Yes, just flash over. With trickster I found Ondemand governor to be ideal. Oc'ed up to 1500. Your results can vary though...

Eaponte23,

Thanks. It work great now. I finally found the kernal and flash it.

now it will charge + otg at the same time.. you and other were right when saying that the kernal somehow didnt get flash over with the rom.
[Nexus 7 Android Development] Mherder:
Where did you find this install_qv4l2_easycap_nexus7.zip file?

I can't find it anywhere

I bought ANOTHER easycap and it still won't work. I flashed Kangaroo kernel also.

But apparnetly the kernel supports EZCap and this is EASYcap... and apparently they are not the same? This backup camera is so damn frustrating....

Hi all, I have a problem with flashing AutoDroid 1.1/1.2

I've had Android 5.1 on my N7, downloaded nakasi-ktu84p factory 4.4.4 image and twrp-2.8.6.0-grouper.img.

Flashed KTU84P system using flash-all.sh, then flashed twrp-2.8.6.0-grouper.img with fastboot flash recovery.

Booted into TWRP, changed filesystems to f2fs:

How to debug this problem and get AutoDroid with f2fs?

Hi guys, how to get my nexus 7 to sleep after his stop power.

What settings should I do in power event manager
[Nexus 7 Android Development] uosiumen:
You need to have an USB OTG Y-cable with connected charger.

Then you enable fixed install mode, fast charge (2A charger needed) and firm sleep.
[Nexus 7 Android Development] dancho01:
function only in OTG cable you work My OTG cable has not come yet and now try directly from the charger Upon awakening everything is fine, but sleeping is not taught, Prevent power and nothing
[Nexus 7 Android Development] Nsx93:
Fast charging doesn't work for me on kangaroo kernel. But does work on oxydo kernel v18.. Now my nexus will stay charged all the time, even when GPS, music, internet are being used..
[Nexus 7 Android Development] samcraig:
Fast charging isnt working for me either but I dont know if its the kernel or the charger. When I check on battery widget it doesnt show me amps but says im charging a little over 4volts. I plan on ordering a 5v 2.4a charger and trying that before I swap out the kernel
[Nexus 7 Android Development] crzycrkr:
I've tried both with the same charger. Was definitely kernel for me

stuck on Google logo?

for those having trouble flashing this per the op instructions... i have a workaround. Follow the op instructions for converting to f2fs (since its faster than the old manual method). once converted to f2fs, reboot recovery, then reboot into the bootloader and fastboot flash the recovery from this thread http://xdaforums.com/showthread.php?t=2678140 flash your rom and gapps from there and reboot... worked like a charm for me, hope this helps.

hi guys, i've a nexus 7 wifi (grouper) but i can't install this rom.

I tried to install the 1.2 without gapps, but i can see only the boot logo "slimkat", after 30 minutes I have to shutdown the device...

the same result if I install the 1.2 with CM gapps, with slimkat gapps (the mini gapps), or the 1.1 with slimkat gapps

I don't know how to install the rom, I also tried to install the rom with multirom

I didn't understood if I must change the filesystem to F2FS or if it's only a raccomandation, however I tried to install in F2FS (data, cache and system) and in EXT4
[Nexus 7 Android Development] crzycrkr:

[Nexus 7 Android Development] mity93:
what kernel do I have to install? i just tried the "kangv2" but doesn't works
[Nexus 7 Android Development] Quick2822:
I haven't had much luck either. I installed the ROM, flashed the v1.2 kernel recommended a page or two ago, no luck. It just hangs on the Google logo. I've tried both EXT4 and F2FS.
[Nexus 7 Android Development] Nsx93:
You need to dirty flash this ROM on top of slimkat ROM..

Download slimkat ROM f2fs grouper. Let it completely load.

Reboot into recovery

Flash autodroid f2fs version without any wipe.

Flash gapps

Flash kernel

Reboot system. Let it run, up to 5mins at the boot screen.

Once it booted it will be wonky.

Reboot to recovery

Wipe for new install

Reflash autodroid

Gapps

Kernel

Reboot system

Then it should be good to go..

Why so many stepsd? I don't know, but that is how i got mine to work..
[Nexus 7 Android Development] Quick2822:
Thanks for the tips, unfortunately no luck. Flashed Slim-grouper-4.4.2.build.4.8-WEEKLY-3876-F2FS.zip, booted up. Back in recovery, flash AutoDroid, Gapps and Kangaroo v1.2 and reboot it will just sit at the Google boot screen.

Just to clarify, which is the recommended kernel? I've seen Kangaroo and Oxydo v18 come up.
[Nexus 7 Android Development] Quick2822:
Oxydo v18 with AutoDroid boots, but unless I'm missing something, firm sleep doesn't seem to work. It's enabled, but when power is removed, nothing happens. Also, when power is restored, no change either.
[Nexus 7 Android Development] Nsx93:
Are you using the special twrp recovery? The one with the red arrow. I would try a full format wipe first. Then flash either the slimkat or paranoid ROM, then try again. Other then that, I have no idea. Sorry.

---------- Post added at 07:58 AM ---------- Previous post was at 07:55 AM ----------

Oxydo v18 works for me, firm sleep and everything. Once its enabled in the power event setting, you need to go into SuperSu and make sure its granted root permission always. Kangaroo 1.2 doesn't work for fast charge on my nexus, everything else works.

Oxydo does not work correctly with otg drive.. Will freeze device..[COLOR="Silver"
[Nexus 7 Android Development] crzycrkr:
The above directions returned for me except for one thing. I couldn't get f2fs going no matter what I did. Oxymodo fast charges for me but is erratic in handling otg. Kangaroo doesn't fast charge, but no problems with otg
[Nexus 7 Android Development] Quick2822:
Thanks for all your help, not sure why I can't get firm sleep to work. Verified it has SuperSu permissions (see the notification come up when I enable or disable it). But removing a charging cable does nothing to the tablet.

I'll keep playing around, I have my truck ripped apart ready to go as soon as I figure this out! :)
[Nexus 7 Android Development] Nsx93:
I forgot, u MUST use an OTG Y cable for firm sleep to work.
