[Nexus 7 Android Development] B|acknd:
I ended up switching back to Autodroid a couple months ago due to the sound quality. I wish i could find a trouble free solution....

With Autodroid i was still having issues getting it to sleep when the ignition turned off. I ended up unplugging the cable from the car charger and plugged it into the USB hub. Now it shuts off the first time. (when everything else is working properly)

OTG + charging is my new challenge.... it will work fine for days/weeks.....then out of the blue it will quit charging and says it is unplugged, and of course quits putting the tablet to sleep when the ignition is turned off. luckily I have easy access to the power button. when it does this, I plug a USB battery pack in and let it charge. Eventually it will randomly start working fine again.

Once the weather warms back up, I'm going to tear it all out my dash and redo my wiring.

Just my story about the installation of Autodroid 1.2 in my Nexus ...

I tried more than 10 times to install this rom in F2FS ... trying to install directly the rom after all the wipes was not working (stuck in the blinking SlimKat logo ).

After I read to install first the normal SlimKat rom so I installed the build 4.8 from here https://xdaforums.com/showthread.php?t=2678142 and after, without wipes, the Autodroid. Like this it was booting but the Power Event Manager was not recognizing the OTG Y cable so the Nexus was not charging. Fixed install mode and Fast charge in host mode was turn on but turning off by itself every time I was closing the Power Event Manager. Super Su installed and Access to superuser granted.

After I read that somebody solved installing again the Kernel. I found this at this link https://drive.google.com/file/d/0BxJ7goWNuNmiRE9JV2stQlVEUE0/view

I tried to flash it but without lucky (again stuck in the blinking SlimKat logo). Maybe because the kernel was not F2FS :confused: ???

I decided to go back to EXT4 so I formatted again everything ... install Slim-grouper-4.4.2.build.4.8 and after, without wipes, the Autodroid.

Again the Power Event Manager (Fixed install mode and Fast charge in host mode on and Superuser granted) was not working (not charging from the OTG Y cable).

I flashed the Kernel without wipes and the Power Event Manager started work like it should be. Charging and reading music from an USB flash drive and play via an external DAC :good::)

Now one question ... Can I convert the kernel to F2FS? If yes I would like to repeat everything formatting first in F2FS

Nexus 7 2012 grouper issues Autodroid 1.2

Hello guys how are you all doing?ive recently been able to install the rom on my tablet but have some issues.the battery drains while in charge and when I turn my car off,tablet goes to sleep mode.but after let’s say 3/4 hours when I get back to my car and turn it on,the tablet won’t boot back up I have to take it out and long press on the on button for it to turn on,and when it turns back on,the battery will be very low.any thoughts on what this could be?i tried reinstalling the rom but same issue
[Nexus 7 Android Development] Viktorbossov:
Remove the battery and use external power adapter

[Nexus 7 Android Development] Drexxter:
And...Yep. I try to start it in 2018! :)

Flash TWRP 3.2.3-0,

Change System/Cache/Data file system to F2FS,

Flash "kangaroo kernel v2",

Flash "AutoDroid 1.2",

And it hangs on "Google" logo.

Change System/Cache/Data file system to EXT4,

Flash "kangaroo kernel v2",

And it hangs on "SLimkat" logo.....

What I doing wrong?
[Nexus 7 Android Development] M95M:
I had the same problem. Today I was trying to get charging on my Nexus 7 in car. I was using Android 7.1.2 Ressurection.

So I need this ROM to get working car dash.

You need to downgrade to Android 4.4.4 at first.

You can use Nexus Tool Kit and install KTU84P image for Nexus 7.

Then reboot in fastboot and flash TWRP recovery 2.8.3 for Android 4.4

Reboot in recovery and flash this ROM.

After this, my Nexus was working again.

ROM look really clean and smooth. Without any problems now.
[Nexus 7 Android Development] screwfunk:
I followed this exactly, I used the nexus root toolkit and flashed the factory KTU84P. Problem is, when I fastbbot and install twrp 2.8.3 and then try to boot into recovery it just hangs. So I flashed "twrp-3.0.2-0-flo.img" and it works. I then open twrp and install autodroid, reboot......Google screen frozen. I am lost and do not know how to move forward... ANy help would be greatly appreciated.

[Nexus 7 Android Development] michiil:
as i said i cant help you with kernel issues.. you could try flashing oxydo kernel and tell me if the problem still persists (:
[Nexus 7 Android Development] redeyedjedi:
Hmm. .....with trickster mod you can enable adb over WiFi and from a laptop with the Android sdk you can "adb logcat"

A sleep of death is a total crash...meaning no function of rom or kernel. You are getting notifications, so you have a kernel and rom that are live and running, and you are not using firm sleep....which means pwrevntmanager isn't trying to wake the tablet up. It should still waKe up if you have checked "wake when power cable is plugged/unplugged."

If you are using firm sleep it isn't working, there would be no notifications etc.

I would love to see a logcat of this. I am aware my kernel could have an issue but I've been using with the 7/19 build for a week now (with my kernel)......no reboots, same charge! (Endurance testing)

Your issue could be my fault but I need a logcat, as I am simply not having any problems.

Use oxydo. ....all other aspects being UNCHANGED.....and see if the issue persists. First...make sure pwrevntmanager is getting superuser permission.

Oxydo is plenty stable.....but I'm not sure he has all the USB dac stuff. He has a lot of experience tho.... a good Ole fashioned code-junky!
[Nexus 7 Android Development] michiil:
Still on the 19 build? Why not f2fs and media keys? (:

Also do you know nice media key icons? Mine are pretty ugly and im a total noob with gimp or photoshop..

Hey (:

I taked to _crue_ and he alows me to implement his powereventmanager app im my rom and he is even modifying it a bit to act like a system app(:

I pan to implement it into the settings but i have to wait until he is finished.

I also asked him about a video on powerdown like timur has it in his nexus 7 2013 rom. Video here ( https://timur.mobi/timurs-kernel-n7-2013/ )

And he said he will definetly try. so pretty awsome things to come :D
[Nexus 7 Android Development] redeyedjedi:
Didn't know the media keys were there.....I will find some sweet icons.....

Any other feature requests you get let me know...glad to help.

Still on old build because I've been working on the 3.4 kernel.....along with many other guys. If we get that Goin. ....TONS of new hardware can be supported....

[Nexus 7 Android Development] gregthomas129:
Awesome!!! Can't wait!
[Nexus 7 Android Development] michiil:
I wont give any eta but it wont be too long (:
[Nexus 7 Android Development] michiil:
Hey guys (:

You could start searching for powerdown videos to use (:

The should be eather the excat same resolution (or ratio) than the nexus 7 or have a black background (otherwise you would have black stripes).

It should be about 5 seconds long since with video on powerdown there is no countdown. The device goes to sleep when the video ends (:

The best place to look are car commercial, you need to cut out the needet part. I will add all videos posted to the op (:
[Nexus 7 Android Development] gregthomas129:
There's several on YouTube. I downloaded a couple for my Mustang. What format do they need to be in? Mine are mp4.
[Nexus 7 Android Development] michiil:
all suppoerted codec are: H.263, H.264 AVC, MPEG4-SP, VP8
[Nexus 7 Android Development] RoNeReR:
i can make one on sony vegas..

give me idea
[Nexus 7 Android Development] michiil:
Well i already got the one i use (: maby someone else has suggestions?
[Nexus 7 Android Development] RoNeReR:
ok i create one with Honda logo

click here
[Nexus 7 Android Development] michiil:
Look awsome (: but:

As i said the video has to be in the codec i mentiond previous post, and it should be with a black background or have the exact same res than the nexus 7 (1280 x 800) or you are going to have black stripes (:

The supportet formats can be found here: (under video)

http://developer.android.com/guide/appendix/media-formats.html
[Nexus 7 Android Development] RoNeReR:
Ok.. I will fix that and add maybe more designs...

At now i back to usb rom.. Too much problem with stability..

Sometimes after night the tablet not power on and only hold power on button fix that... Sometime the sleep on powerloss not working..

I hope it will fix in the next rom..
[Nexus 7 Android Development] michiil:
why didnt you say anything? since what build are you experiencing this issues?

Does really nobody here use f2fs? because i just noticed that is was broken since latest build and nobody complaned (:

you guys should really try it out you can really feel the performace improvemets (:
[Nexus 7 Android Development] Iceman_jkh:
I don't know what it is...*goes off to Google it*?

A file system? I'm still using ext4 I think.
[Nexus 7 Android Development] michiil:
yes its a file system (: if you are running the lastest twrp version you are able to change to f2fs in there (:

i think i am going to write a little how to in the op (:
[Nexus 7 Android Development] redeyedjedi:
I just realized that my kernel is not defaulting to the on demand governor. The interactive governor is terrible and buggy but it is defaulting to it in the ram disk. Using trickster mod to put it on "on demand" fixes this....but there is a way to do it in the ram disk. I think that's why greg Thomas was getting Sleep of death....interactive governor on my kernel is crazy bad......while the custom on demand governor by showp is crazy good. I'm sorry for the crappie user experience people. I'll get the default fixed to on demand. In the meantime just use trickster mad and change it.....or, shun me and go to oxydo!
[Nexus 7 Android Development] gregthomas129:
I'll give this a try. (Fingers crossed)
[Nexus 7 Android Development] michiil:
Wait an hour or so (:

Then you will get a new build with fixed default govener, the new powereventmanager includet in setting and fixed f2fs witch i would really recommen to all of you (:
[Nexus 7 Android Development] gregthomas129:
So I switch to f2fs in twrp before I flash? I'll try this if I can figure it out.
[Nexus 7 Android Development] michiil:
I have written a little how to in the op (:

Yes you change fs and than you flash the rom (: but you need adb because on changing your whole storage will be erased (:

EDIT: Okay no new build today. My internet is down so i cant upload it..

Expect the build tomorrow (:

Does anyone now if the keyboard map has changed with this rom? I use a Joycon device for steering wheel controls and the home button and back button no longer work. They worked on other roms such as kangarom and cm11.

[Nexus 7 Android Development] dmok:
So far so good: changing default governor to ondemand fixes a bunch of problems for me, including sleep of death, lag in browser, skype issues, ... Cool, I like this rom more and more. Thanks.

d.
[Nexus 7 Android Development] Iceman_jkh:
I use one too. I don't use home/back, but the other buttons I tested so far (power, play, mute, prev, next) worked fine.
[Nexus 7 Android Development] j41224:
Those keyboard buttons work for me as well just the home and back button do not work anymore. The home button is typically mapped as www or web(normally used to open a Web browser) and the back button is normally mapped as the escape or backspace button I can't remember which at the moment. Each button on the Joycon can be set for a single press or a long press. Each button still works because their other mapping(single or long press) still works. For example, the mode button on my steering wheel, single press is pause and works but long press is the home button which doesn't work. I was just wondering if someone could check the external keyboard map against kangarom and see if they are different or tell me where it should be located and I'll check it.

Sent from my Wicked Galaxy S4
[Nexus 7 Android Development] redeyedjedi:
Let me look and I'll see. I'd guess the issue is not that there were changes from 4.4.3 to 4.4.4 but that kangarom is aosp based and slimrom is cm based. I bet those files are swappable too.

https://github.com/lostdeveloper/platform_frameworks_base/tree/kitkat/data/keyboards

this is where your "good" one came from.....

...and this is where the "bad" one resides:

/system/usr/keylayout/

You need rw access to /system. I'd suggest editing the ones already there using the ones from kangarom as a guide. Find a setup that works and share it here....I'll push it to git hub if it doesn't conflict anywhere else. I don't think OP will mind having joy con compatibility.
[Nexus 7 Android Development] michiil:
your right i wouldnt midn (:

______________________________________________________

ok i just test last version... with f2fs

and this is my issues...

1. there is no landscape boot animation..

2. i use poweramp to music and have some lag on music ( i change priority to high and it help little...)

3. the app caro0 is crash on start..

there is any chance to add a option to use usbcam as "rear" cam?

i use biggest font from setting.. and its feel little small than usbrom. any change to get bigger font?

there is twrp version that work in landscape? my neck broke when updating rom

_crue_

there is any chance to make wakeup image..?

i think it will be nice to start my car and get wellcome message from my tablet
[Nexus 7 Android Development] michiil:
1. yes i noticed that to but i just wantet to finally get this build up (: i postet a bootanimation a few post back you can use that one in the meantime

2. wierd.. will try this out tomorrow. i use spotify and everything is fine

3. i have nerver heard of this app before and i didnt eperiance this crash.. do you get it on every boot or only on the first boot?

webcam or easycap? the needet driver files for easycap are includet in the rom. afaik the rest is a app thing. please tell me if im wrong..

you will find information on the timurs rom thread (:

Yes you need to change the dpi (. slim is a bit smaller on default. more info here: http://slimroms.net/index.php/faq/slimbean/415-will-you-add-the-dpi-changer-in-settings-in-slimkat

I dont think so but i do think that i can make one (:

the wakeup image has nothing to do with the powereventmager app of _crue_ . the app puts the device to sleep, it wakes up on its own when it gets power from the charger. i think it woulb be really hard to put an image there fast enaugh to look good..

peace
[Nexus 7 Android Development] redeyedjedi:
There is a method to use USB Webcam as a "rear" cam....look in 2nd, 3rd post of kangaroo kernel thread.

For bigger font....LOWER the dpi in build.prop

twrp already has landscape.....it can be turned on in recovery.

forget power amp. ....get neutron or double twist.
[Nexus 7 Android Development] Iceman_jkh:
Or Gonemad Music Player.

RoNeReR> Could you please make a reverse landscape version of your Android power down video.

My nexus is mounted in "reverse landscape" (hardware buttons on bottom

edge).

I've also got a febon100 UVC capture device for reverse camera. Even though the drivers are included in the ROM, I don't believe the car cam app (which acts as the reverse gear detector and displays the video feed on demand) has been updated for almost 6 months. ?.. and it's not quite working properly (for febons) in its current state.​
[Nexus 7 Android Development] redeyedjedi:
+1 for gonemad as well....

the Febon uvc should work with simplewebcam.

I don't think car cam will be updated.....but I hope to work with crue for a better solution....with ffmpeg and yadiff. ....properly de-interlaced video that isn't choppy. Dmitrysmol has been active on the Russian pccar.ru forum....but hasn't updated the app.​
[Nexus 7 Android Development] gregthomas129:
Bug maybe? If I turn the key off and the shutdown video starts then turn the key back on the tablet continues to shutdown. Then if I turn the key back off again the tablet comes on. Once I turn the key back on it stays on then. This causes me problems sometime if I start the car while the tablet is on, the ignition goes on and off quickly while the car starts. Video below...

Slimrom shutdown animation: http://youtu.be/g6RigznE-hQ
[Nexus 7 Android Development] redeyedjedi:
It's not looking for power until it goes to sleep......it doesn't call 'gotosleep' until the video ends. Waiting for the tablet to sleep is the only way it will respond to a power event. I believe crue had a cancel button....or a press anywhere to cancel function...... if so you would need to hit cancel or back if you turn the key back on too quickly....

The right way would be to add a subroutine that would automatically cancel the 'gotosleep' command if it detected a power event before the gotosleep command is given at the end of the video.... the moment where the superuser granted toast pops up to be exact. I'll ask crue. .. I think he wants to figure out a "hello" or wakeup video too.

nice setup BTW.
[Nexus 7 Android Development] gregthomas129:
Thanks. I don't remember seeing any way to cancel. I tried a tasker profile that detects the screen off and checks for power and turns the screen back on if it sees power but I had no luck with it. So far it's working ok, but every once in a while it happens and the only way to get it back right is to cycle the key switch again.
[Nexus 7 Android Development] michiil:
To cance you touch the screen while the video plays, then the navbar comes up and you can press back to cancel (:
[Nexus 7 Android Development] gregthomas129:
Ahhhhh i see! Thanks I'll try that.
[Nexus 7 Android Development] michiil:
Hmm i think the video always plays in the orientation where the tablet currently is.. Have you tried it?​
[Nexus 7 Android Development] j41224:
Could someone check in to bluetooth tethering. It really saves battery. My phone shows the tablet is connected to the bluetooth Hotspot and the tablet shows the bluetooth icon in white indicating a bluetooth Internet connection but no data is passed to anything. If I switch to wifi it works. I also use bluetooth for autovoice commands to autoremote and I can pass commands back and forth from my bluetooth mic, connected to my phone, to the tablet for song searches mainly. This no longer works either without bluetooth tethering. I can switch everything to wifi but it uses more battery. Any help would be greatly appreciated.
