True. I didn't really think about mtp capable cars. Most I have seen have been iPhone capable, but not mtp. I use Spotify and Google music all access, so the digital rights management makes mtp moot for me anyway.

What type of vehicle is it?

Is your music a subscription service like Spotify or Google all access? Or are you just using Google music to play files you downloaded elsewhere?

gps issues?

anybody have gps issues with autodroid rom? i took a long drive norcal>socal and back and had it tethered to my SGN2 on VZW. Gmusic didn't have any issues streaming music the whole way, but gps was miserable and didn't work for gMaps or Waze. i double checked to make sure location services boxes were checked on. It just couldn't properly locate where i was or keep up with me moving. I never had this problem on usbrom.

[Nexus 7 Android Development] michiil:
Nope never heard of it.. Clean flash?
[Nexus 7 Android Development] michiil:
Well theres timurs rom. You have to pay him to use it but it has a simmilar set of features..
[Nexus 7 Android Development] michiil:
You shouldnt have to flash any rom before you flash this. Also it shouldnt matter if you are on f2fs or on ext4 (i tested both)

Somethings definetly wrong with your flashing..

When you say you flash stock do you mean a factory image?

If not you should do that. Than flash the newest version of twrp via fastboot and than flash this rom + gapps. F2fs or not is your desition. If you want f2fs be shure that all partition are succesfully converted.

USB-DAC

Hello michiil!

I saw the usb-dac support capability, but will work with any usb sound card through the OTG cable? Possibly 5.1 channel support? I'd like to use a Sound Blaster X-Fi Surround 5.1 Pro (SB1095). Any chance? Cheers
[Nexus 7 Android Development] michiil:
It will work with most usb soundcards. But only sterio afaik..

You could try it amd report back (:
[Nexus 7 Android Development] sje0123:
Been using everything now for a couple of months and have everything working well. I was finally able to find an OTG cable with large enough gauge wiring to allow for proper charging.

I am running into two issues with the ROM.

1: I have remote start on my car and when it is turning on it flips to ACC then pauses and then turns the car on. When the car starts it cuts power to everything to power the starter (like every car). When the tab senses loss in power it goes to sleep. No matter how long I delay the shut down through PowerEvent Manager it will still put it to deep sleep. Does anyone else have this issue? I would think that when it sensed power again during countdown screen it would cancel deep sleep. Obviously I am not in the car so I cannot stop it manually and even then when I hit the home button to cancel it still proceeds to deep sleep.

2: I have noticed that even when the tablet is in deep sleep from power loss the DAC and JoyCon are powered. Their power indicator LEDs are lit. I have been seeing drastic loss of battery over night. I will say that the cold def has an effect on the power loss. Batteries just don't do well in cold. I have unplugged the OTG to test this and overnight I lose 15%-20% from cold alone. This is something we cannot remedy. However, with OTG plugged in overnight and the DAC/JoyCon staying lit I lose 50+%. Is the power to the DAC and JoyCon supposed to be cut in deep sleep and mine just isnt doing it? If this is an issue what is the best solution to cut power to them?

Make sure that the back plate on your tablet is completely connected, it doesn't take much for the GPS module to disconnect.

---------- Post added at 04:13 PM ---------- Previous post was at 03:37 PM ----------

1. One of my old builds was in a car with an automatic starter, It doesn't work really well, the best way to use the starter and the tablet is to press the brake when you get in or whatever turns off your engine, let the screen turn off and then restart the car, I know its a pain but that's your best bet if you don't want to get an intelligent dc-dc converter.

2. Sounds like an issue with the fixed install mode, deactivate it and re-enable it, Power the tablet completely off and if possible clear cache in recovery then it should be set back to normal.

2A. Yes, cold temps destroy the battery, in my car in the summer the battery barely moves. In the winter the battery drops a lot faster. I remember not leaving the house for 2 days last winter and the tab was dead.

---------- Post added at 04:14 PM ---------- Previous post was at 04:13 PM ----------

I'm pretty sure Timur's Kernel enabled all USB audio devices. Don't quote me on that but I recall seeing it somewhere
[Nexus 7 Android Development] sje0123:
Makes sense. What I have been doing lately is just taking a magnet to the bottom right of the screen and waking it that way. Then just turn off airplane mode. Not all that much of a hassle since it is one time a day. Ive powered off and on trying to fix the always on DAC issue. Ill boot to recovery and clear cache to see if it helps.

Thanks for the suggestions.
[Nexus 7 Android Development] Iceman_jkh:
Rather than starting a new thread, I'll ask here in case others are interested or in case this has already been solved:

1. Is there any way (app, terminal cmd, xposed module, etc) to allow my nexus 7 to copy/download files (ie songs) from my phone's storage, when the phone is plugged into the nexus via the OTG cable? (Camera importer usually pops up and tries to copy photos /images over, so I know the nexus can definitely see the files on my Samsung Galaxy S3). I'm not looking for a solution that involves WiFi or BT connection, only USB thanks.

2. Is there any way for my galaxy s3 to detect when it's plugged into (the OTG of) the nexus via USB? I want to be able to tell when it's plugged into my nexus 7 specifically, not just plugged into any PC / USB device. (Again, I want to utilise the USB connection only (if possible) to determine this state. I plan to run certain Tasker scripts on connect /disconnect).

Thanks ?
[Nexus 7 Android Development] MetalMan2:
Do you use Tablet Talk between S3 and N7? If so, you can use a "BT Connected" profile in Tasker (on both N7 and S3) and use that to trigger a variable, let's say called BT connected. So whenever you have your S3 and N7 nearby and the ignition is on, using this variable BT connected you can automate various functions.

This is what I do and it's quite reliable (except if/when Tablet Talk randomly/rarely crashes).
[Nexus 7 Android Development] Iceman_jkh:
Thanks MetalMan.

I do, however I was hoping to be able to use TabletTalk via USB (not currently possible it seems), as I may have to use BT to receive DAB+ radio audio stream.

I'll try the BT method in the interim, but ultimately hoping there is an easy way (perhaps even a simple app/script can be written) so the phone knows when it's connected to the N7 (I guess using vendor ID and product ID).

I can confirm the kernel issue.

I restored from factory images then installed the zip and the stock kernel was in place. Then wiped again installed slimrom installed autodroid and still slimrom's default kernel was in place. Then i installed kangaroo manually and worked great. (All with latest twrp)
[Nexus 7 Android Development] dadoreverend:
Same problem here, kernel doesn't boot with f2fs, i've tried differents how-to, 4 recovery versions, starting by stock, ecc ecc ecc.

the only way to boot f2fs is changing kernel with one compatible. this rom is dead? i hope not... bye
[Nexus 7 Android Development] Iceman_jkh:
Worked fine for me.

I used TWRP (latest version) to change all the partitions to f2fs. NOTE: This will wipe all data from those partitions.

I then used adb to transfer the ROM (.zip) file (from my PC to the Nexus 7) onto the main partition (or Downloads directory, etc). Then just flash the .zip as you normally would in TWRP. It worked fine.

Make sure that you change back to non-f2fs (all partitions) if you decide to use a different ROM again (unless that ROM is also f2fs compatible).

Grouper. I'll check what version later today.

Update: I've since removed that install of AutoDroid, however I was using the latest version 1.2. Unfortunately, therefore I cannot actually check which bootloader version it was.

sound issues

Hi all

İ havent installed my nexus to my car yet. But trying something about sound connections. When i want to load navigation app and google music at the same time sound dies. Neither audio nor video apps works. After a reboot it gets ok. This happens when connecting the tablet over aux. But over bluetooth everything works fine. Anyone having a problem like that? İ want to connect it over aux but having this.
[Nexus 7 Android Development] 91ludesit:
I could never make the rom work, even after manually flashing kangaroo kernel on top. It refused to detect my usb host cable, dac, etc. Back to USBROM I guess.
[Nexus 7 Android Development] papinist:
this rom is not maintained anymore from the OP, and no one is trying to continue his work.
[Nexus 7 Android Development] poissonn:
Maybe someone could help me get this ROM working on my N7. I come from Timur's usb rom and it's been flawless for the past year. But now I wanted to try something different. I'm having a hard time getting the fixed install mode working. When I toggle any settings ON in the power event manager, I get a pop-up mentionning super user access were granted to power event manager but still, as soon as I leave the settings page, it completely resets itself and the fixed install toggle is back to OFF. I thought it was a Super user problem but I don't get it since the pop up clearly indicates it's getting SU access...

anything I might be missing?
[Nexus 7 Android Development] gregthomas129:
Look in the SuperSU app and see if the log indicates it did in fact get granted super user access. Have u tried rebooting or reflashing? Do you have it hooked to an otg cable?
[Nexus 7 Android Development] poissonn:
the log indeed confirms it granted access. It's hooked up to the same otg cable I used with timur's rom so I think we're all good for this part. I might try reflashing as I did reboot countless times...

I have a powered usb hub on which the otg cable is connected as well as my usb dac. The dac works just fine when I connect my N7 to it through the hub. but the tablet itself won't charge through usb-otg.

thanks for the quick reply btw!
[Nexus 7 Android Development] gregthomas129:
No problem. Before you try a reflash, maybe go into app settings and clear all data on the power manager app.

been trying for the last 2 days to install this ROM.. what is the right way?

I have try with WUGFRESH and CWM and TWRP

I have tried version 1.1 and 1.2. the kernel gets installed but I never see any thing else?

current rom is 4.4.4 stock kitkat (rooted and Unlocked)

HELP
[Nexus 7 Android Development] -=Jeff=-:
Got it working finally.. Now to test it out
[Nexus 7 Android Development] crzycrkr:
What did you do? I can't seem to get past the splash screen when flashing the f2fs build
[Nexus 7 Android Development] 91ludesit:
I love when people post that they got something and don't share what they did with others.
[Nexus 7 Android Development] -=Jeff=-:
Sorry life and family got in the way.. When I got it working I thought posting I had it working would save the hassle of someone typing out what to do..

How I got it working:

-Flashed OEM 4.4.4 (was on slooooowwwww 5.0) using NRT

-Rooted it/installed CWM using NRT

-Copied Auto Droid to the device using Windows Explorer

-copied Slim GA Apps to the device using Windows Explorer

-Rebooted into CWM recovery using the DEVICE ONLY

-Followed guide as to what to format/wipe etc on Slimkat website on DEVICE

-installed ROM then GApps from CWM ON DEVICE

-Rebooted and done

There is how I did it YMMV

EDIT: I DID NOT USE F2FS
[Nexus 7 Android Development] crzycrkr:
I think that is where my problem is coming in. I'm using f2fs. Wish there was just a 5.0 kernel to give otg+charging
[Nexus 7 Android Development] project_86:
I gave my N7 to my parents to use for a year but they did'nt use it, so they gave it back. Is it normal that the battery % does not increase while it is in use? Wifi only enabled, screen on at ~30%. Using tasker to throttle the CPU down to 600mhz and pixel battery saver to disable pixels and still it hangs on the same %. If I shut the screen off it charges up.

I think they may have left it plugged in to the wall for the entire year and screwed the battery over. That or I just don't remember it taking so long to charge.
[Nexus 7 Android Development] sje0123:
Check your charger. May be a weak one if not OEM one. You can download an app like Current Widget: Battery Monitor to see what the mA is during charging.
[Nexus 7 Android Development] project_86:
So it turned out to be an app called Minimal Text Widgets or something like that I had on the home screen, which was running the CPU up a lot. Idk how I didn't catch it before. I kept my mods anyway to see how it performed today. They include,

- Pixel Battery Saver, (disables some number of pixels) set to low

- Auto Brightness

- Tasker keeps the CPU between 102mhz - 620mhz (something close to that) while screen is on

- Various wavelock tweaks

With location and wifi enabled, and the screen on always it did not drop 1% in 1hr while running spotify. I'm going to try it tomorrow with Pixel Bat. Saver disabled or on minimal.
[Nexus 7 Android Development] JagXK8:
+1:fingers-crossed:
[Nexus 7 Android Development] sirofpatrick:
+1
[Nexus 7 Android Development] !crazy:
Your battery saving attempts are mostly totally useless, and have opposite effect. That **** app poses saver turns pixels black to save energy, and that moron lies, or just talks nonsense when he claims that black pixels will save energy even on other types of screen than amoled. Black pixels use more power than white ones.

Also regarding CPU, it is not always (depends on usage) good to allow it to run on lower frequencies. On higher frequencies CPU will complete task sooner, and be able to turn it self or to use one of its power saving states. That depends on CPU, b/c they have different power saving features implemented and behave differently.

Regarding pixel saver just check the comments, and read the app description. He will (and already has) introduce (d) 'Antivirus' app as a part of his pixel app.
[Nexus 7 Android Development] project_86:
Thank you. I saw some negative comments but thought I'd give it a go myself and I noticed improvement. Maybe it was only the wavelock features that improved the battery life and the others were negligable or no savings. I will remove the pixel app and see what happens. Thanks again for bringing this to my attn.

Usb drive and OTG Y cable

I've flashed (and re-flashed) autodroid trying to get the "Lock USB drive" feature working in Power Manager, but to no avail. It seems like my Nexus cant see my USB drive (a 16GB stick) unless there is power running to the OTG cable. So when power is disconnected the usb drive gets unmounted before Power Manager has a chance to lock it. Is this normal, or are there OTG Y cables out there that let you mount a usb stick without plugging it in?
[Nexus 7 Android Development] Namheul:
Tried to install this today, but the first boot after flashing just sits at the "SlimKAT" animation forever.

Was on CM10.2, did a full wipe in TWRP before flashing this.

Any ideas?

Very nice ROM! Everything works perfectly for the setup I am making for my car however the easycap refuses to work for me. I tried multiple easycap devices until coming across the Sabrent STK1160 that everyone keeps reporting are working. It shows up on the emulated terminal as /dev/video0 and even changing permissions with chmod to 777 or 666 I am still unable to view it in carcam 1.3 or 1.4bbb. Only thing I get is a black screen so if anyone could help to point me in the right direction I would really appreciate it.
[Nexus 7 Android Development] papinist:
if you use an usb extension, remove it or change it. With an usb extension I had lots of problems... changing it solved it all!
[Nexus 7 Android Development] Walz83:
I had two issues with my easycap

1- USB hub wasn't providing enough power to the easycap. fixed by getting powered USB hub

2- The screen was flickering. I had a long extension cable so I reduced the cable length and that fixed it.

FYI i have easycap STK1160 and works flawlessly with carcam 1.4bbb

Hi Guys,

I got my setup working great, the only issue i'm having is fastcharge is not working.

I got one of these to test hows much current I'm drawing http://www.ebay.com.au/itm/271542195208?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Its only charging at ~650mA when in host mode (with y-splitter cable) and ~850mA when not in host mode (plugged directly into wall charger). I believe fastcharge should be at close to 2A.

Any ideas please. Note that USB host mode and power event manager all work perfectly fine.

Great news [MENTION=1017474]Rage2[/MENTION] !

Couple of questions :

1. Who is the author : [MENTION=5285877]michiil[/MENTION] or [MENTION=4035939]redeyedjedi[/MENTION] or someone else?

2. Are the drivers compiled as modules for the stock kernels 4.4.4 and 5.0? If this is the case it won't work on other kernels ?

3. Will there be trial version (it makes sense to test apps like that)? Maybe limited to 30 seconds will be enough.
[Nexus 7 Android Development] briangig:
I was in the same boat. I couldn't get my Sabrent STK1160 to work even when directly connecting the EasyCap to the OTG cable (when plugged into my powered USB Hub, i didn't even get video0).

Eventually I flashed Timur's USB ROM (which is not easy to find, google cm-10.1-20130817-USBROM-grouper.zip or cm-10.1-20130817-USBROM-tilapia.zip). To my surprise, I fired up CarCam, changed to NTSC and I got am image! I then wiped and flashed AutoDroid and like magic it works..auto detect even works great (on bench, installing this weekend weather permitting). It makes no sense, but thats how I got it working. Might also be a good idea to test it on a Windows machine with your camera.
[Nexus 7 Android Development] raksan:
I flashed AutoDroid 1.2 a few times, I think somehow the kernel didn't get flashed and it remained what you have in last rom. So you could flash Autodroid and follow by Kangaroo kernel which has all the module you need to work.
[Nexus 7 Android Development] clumzy1:
yup that is exactly what is happening with me -- plugged directly into the OTG cable i get video0 but no signal and working on the computer so just downloading Timurs to try it now. Thanks again
[Nexus 7 Android Development] briangig:
It is possible, I will check my kernel and see. I have to reflash anyway, as I didn't use F2FS this time.
[Nexus 7 Android Development] rapid_rabbit:
chmod 777 /dev/video0 just for the test
[Nexus 7 Android Development] briangig:
I checked today and it does have Kangaroo Kernel, so the kernel flashed successfully.
[Nexus 7 Android Development] crzycrkr:
Anyone else have really slow charging with a y cable using kangaroo kernel? Oxydo doesn't consistently reconnect the DAC on power up and the fast charge send to work for me. Kangaroo reconnects every time, but show charge. Does charge quickly without the y though
[Nexus 7 Android Development] clumzy1:
Thank you again! I made some progress by trying the timur's USB ROM and finally got the EasyCap to produce an image in CarCam!! Now its just to get AutoDroid to install again -- keeps getting stuck at the SlimKat flashing screen :\ How did the install go/what type of car are you installing on?

Strange, had to flash SlimKat than AutoDroid and finally kangaroo kernel v2 to get AutoDroid back up again with the correct kernel. I'm still stuck at the same as before however - I see in the terminal /dev/video0 and even changing permissions to 777 or 666 I can not get a video signal to work in CarCam (1.4bbb) with nothing but the Y OTG cable connecting the stk1160 to the nexus and the 2amp charger. I'm kind of new to using Android but is there a way I would be able to view logs to see what is going on on the nexus? Thanks again
[Nexus 7 Android Development] Walz83:
I have this issue. When using my stock 2A wall charger, the tablet is drawing ~650mA in host mode (using y-splitter cable) and ~850mA in normal mode. Fascharge should be > 1A
[Nexus 7 Android Development] crzycrkr:
Haven't figured out a fix? It sucks, but each of the two kernels has a pretty large flaw
