Wow!

This ROM is awesome! I just installed this ROM after using SlimKat for years. It's so much faster! It's a long time ago that I used stock ROM but if I had to guess, it's faster than stock ROM! Thank you! I hope you will/can update the security patches ever now and then; would be really awesome!

Hello

well, after flashing your file i was able to flash the GAPPS, however i'm unable to add a google account once the system loaded.

when i press the play icon it opens and i have one option - ADD. when i press it nothing happens.

off course i cleared the cash in between the installations.

[MENTION=1447472]krot84[/MENTION] Did you try adding a Google account from Settings > Users and Accounts > Google?
[Nexus 7 Android Development] krot84:
Tried that too but when I press add it does nothing
[Nexus 7 Android Development] AICProcks!:
[MENTION=1447472]krot84[/MENTION] Are you able to add other accounts besides Google?

A user recently reported that the February 21 Gapps worked fine: https://github.com/opengapps/arm/releases/download/20190221/open_gapps-arm-7.1-pico-20190221.zip

If that doesn't work, you might need to restart all over again, and flash the rom, and February 21 Gapps.

If that also doesn't work, you can try out [MENTION=5653319]JT1510365[/MENTION] crDroid modified rom that already includes Gapps: https://xdaforums.com/nexus-7/development/rom-crdroid-v3-8-9-unofficial-grouper-9-t3844534

Hey guys!

This was a major pita, lol.

I posted over in this thread:

https://xdaforums.com/showpost.php?p=80134124&postcount=1463

Hopefully this is helpful.

If so, please give some credit and pass it onto others! :good: :cool:

EDIT: hey guys, I went ahead and edited the .zip and added in the stock files. This way you can give the stock file a compare against yours, and if it's different, you can see exactly what edits I made, and then you don't end up editing anything unnecessary.The files come from crdroid N stock 7.1 branch.

I've renamed the .zip file with a V2 on it

I delete the google app on my Nexus 7, it noticeably slows it down for me. Holding the home button on my grouper happily does nothing. Just saying, how much do you actually use assistant? Even on my phone I barely use it. You look weird doing it in public, and there are very fews times when you can't just use assistant on your phone/even need to use it in the first place. just my 2 cents.
[Nexus 7 Android Development] CamoGeko:
Hey, can you post the kernel settings that you use? Intelliactive?

Also, does anyone know how to turn off fading black borders on the home screen? I can't find the option anywhere.
[Nexus 7 Android Development] AICProcks!:
I currently don't use any manual settings for the kernel; all of the kernel settings are default.

Regarding the home screen fading black borders, are you using the default home screen app or Nova Launcher? I myself am using Nova Launcher, and don't see any fading black borders.

Hello [MENTION=8323115]AICProcks![/MENTION] ,

First I would like to thank you for your work on our aging device!

I have a few questions:

1) Do you experience you tablet not responding and then just "resetting" back to the home screen?

2) Would Parot mod be useful? I am using f2fs on both data and cache but system still ext4.

3) Charging speeds show 50 mA???? It might be faulty HW but maybe enabling Fast Charge on the kernel might help??

4) My speakers (past 40%) start popping again i feel like when i went in to repair my Screen from a fall they managed to screw up other things, which is why i had not used it since 2013.

I would be happy to help as I am a semi-new programmer. Tho i have not dabbled in Android Rom Development. Thanks!
[Nexus 7 Android Development] AICProcks!:
Sometimes, I experience the tablet not responding and resetting to the home screen, but only when I open up like 5+ tabs in my Atlas Internet Browser, or when I open a page that uses a lot of resources. But, I experience this random "freezing" on every Nougat 7.1.2 rom for the Nexus 7 2012 (grouper), even on the Pure Nexus 6.0 rom with the Parrot mod. When this happens, I either force close my Internet Browser, by holding down the Back button, which usually works. In extreme cases, I just force reboot the tablet with the Power button. I am also using F2FS on data and cache, but system still EXT4. Also, I am not really sure if it helps, but I rooted my tablet with SuperSU and uninstalled any unnecessary System apps, such as the default Home app, Browser, Calendar, Music app, File Manager, etc. I replaced these with Nova Launcher, Atlas Browser, ES File Manager, etc.

I am being optimistic that this problem will cease with the new Oreo Go edition designed for tablets with 512 Mb to 1 Gb ram. I don't know when Oreo will be available yet for Grouper, but it seems that Grouper will be supported.

Regarding the charging speed of 50 mA, that's a problem that I solved by simply opening up the tablet and unscrewing the USB port. I unplugged the I/O wire on both ends from the USB port (#2 in the Picture) and from the Motherboard (#1 in the Picture). In particular, the end from the Motherboard was the problem. I had to plug it in "forcefully" and tape it with electrical tape to stay in place. I also taped the USB port (#2) wire end and the battery (#3 in the Picture) so that it wouldn't move around or microscopically unplug the wire. Since then, the tablet charges fully in around 2-3 hours. After this fix, I was careful not to "throw" the tablet, and all is well.

PICTURE

I only experienced speakers popping in Pure Nexus 6.0 rom, and only when the tablet was booting. There was a temporary "fix" flashable zip, but I'm not sure if it applies in your case. Anyhow, the popping speakers "fix" didn't always work. :D
[Nexus 7 Android Development] thagabe:
Sounds good but how do you know grouper will be supported? Who will support the original port to lineage os?
[Nexus 7 Android Development] AICProcks!:
I think it will most likely be an unofficial port. [MENTION=3729448]aaopt[/MENTION] might take over the unofficial Lineage OS Oreo build for Grouper, but you need to confirm with him. They are talking about the porting of Oreo on XDA here. This XDA in particular talks about developing Kernel 3.4 for the Grouper, which should in theory make it smoother, but they are only developing Kernel 3.4 for Unlegacy Android rom. I tried the Unlegacy Android rom with Kernel 3.4, and while it was kind of smoother, it was missing a lot of features that are available in crDroid.
[Nexus 7 Android Development] thagabe:
Kernel 3.4 ugh had that kernel on my last room and I feel like it isn't stable maybe it was just my device but mehhhh
[Nexus 7 Android Development] AICProcks!:
Did you try applying some of the tweaks that they mention in this thread? Maybe those could help you if you didn't.
[Nexus 7 Android Development] thagabe:
I might give it another whirl. Mind giving me a guide on how to build your room or the kernel?
[Nexus 7 Android Development] AICProcks!:
The instructions how to build crDroid for Grouper are in post #2. Use Ubuntu 16.04.3 LTS, and follow the instructions here to download all the necessary packages. In case any packages are missing, try to get the ones from Ubuntu 14, which are most likely already included with Ubuntu 16. You need at least 150 Gb of space. If space or computing power is an issue, you could always try building in Google Cloud.

crDroid provides instructions how to initialize the repo, etc. here. crDroid is mostly based on Lineage OS, which is available for Grouper thanks to Aaopt and the sources he used.

Regarding the kernel, I used AndDiSa's Kernel; I just added it to the Manifest roomservice.xml.

I have a question I try install this room but the gapps when the tablet boot says the first screen where you start to log in crash and I can get out that to enter on the tablet
[Nexus 7 Android Development] hokiealumnus:
crDroid v3.8.4 is Up!

crDroid v3.8.4 for deb/flo is live and ready to go!

Note some devices have a bug where video recording errors when it tries to save 30fps video with Google Camera. 60fps with Google Camera seems ok and the included Snap Camera isn't affected. This post is a copy/paste. If your device is not capable of 60 fps, then obviously 60 fps won't work for you.

As always, download link & instructions are in the OP. Dirty flash should be fine, but remember to always clean flash before reporting any problems. Enjoy! :good:

You have to skip setup by tapping the four corners of the screen, then you can enter your Google account in settings. Known issue; search is your friend. It's a quirk of the device we can't do anything about.

Thanks I will try again tonight

Is it normal for netflix to not work? I downloaded from yalp store but it told me my android version is lower (5.0) while this rom is 7.
[Nexus 7 Android Development] AICProcks!:
It should work. Try to download the Netflix release from this official website. This is the direct download link for the Netflix apk.
[Nexus 7 Android Development] AICProcks!:
I know how frustrating this could be, especially on many Lineage OS based roms that I tried. Luckily, I don't frequently experience this effect on this rom.

However, from what you described, it seems like you enabled double tap on lock screen to shut off the screen? If so, try to disable this option from "Settings> crDroid Settings> Lock Screen> Double tap to sleep anywhere".

Otherwise, try adjusting the "Touch & hold delay" under "Settings> Accessibility".
[Nexus 7 Android Development] Army_Spec_Ops:
It hasn't been enabled.

Hi AICPRocks! Your cdroid is running great! I cannot believe my old nexus is running smoothly again and with the latest versione of android!

You can speed the device up a little more if you enable GPU use for 2D in developer options.

But this is at cost of battery usage. I prefer speed. :D

This is the fastest 7.1 rom.

[MENTION=8323115]AICProcks![/MENTION] Thanks a lot for the rom and build instructions :). I usually prefer near AOSP based roms, but glad I have tried this. I have tested almost every rom and I can easily say this is the fastest and latest non-aosp rom. I was planning to use my old nexus 7 in my car and looking at lineageOS rom to enable a2dp sink support. Even though this rom is based on lineageOS it is much faster. For some reason system UI lags in the lineageOS rom.

I have generated a build with a2dp sink profile enabled and currently using it in my vehicle. Hopefully it will continue to perform as it is now. I see occasional crashes, but my tablet is usable as a navigation system in my car. Looking for updates and fixes ;).

Stuck after reset

So, I installed the Rom. Working great. Factory Reset, went in, works great. Reset it again, and sent it out to a friend. Now it just goes back and forth between these 2 screens. Any thoughts?

Any one got google assistant working on this rom? I have installed the google search app but "Say "Ok Google" any time" is greyed out.
[Nexus 7 Android Development] gmikhail:
[MENTION=1248420]montamer[/MENTION] this is because the applications (Google, Google Launcher (?), Google TTS and many others) is not installed as a system app (/system/app/ & /system/priv-app/). One time I tried to do it, but unfortunately I did not succeed (maybe I did not install all apps or did it wrong). You can google it and try it yourself.

PS: nexus 7 has a small system partition, so you need to remove all unnecessary (or increase the system partition, but this is difficult and can lead to negative consequences). I just booted into TWRP, mounted system partition and through the built-in file manager deleted unnecessary application and files.

Hi,

is it possible to compile the source code for tilapia? I have this device.

When yes, can someone assist me to compile it?
[Nexus 7 Android Development] montamer:
[MENTION=6699143]gmikhail[/MENTION] thanks for the tip. I have installed opengapps-nano package through magisk gapps module and google assistant is working fine now :)
[Nexus 7 Android Development] AICProcks!:
Do you use the 3g on your Tilapia? If not, you can always flash the Grouper TWRP on your Tilapia from https://dl.twrp.me/grouper/. You will be able to use all Grouper roms on your Tilapia then.

I could technically create crDroid for Tilapia, but for some reason, I can't seem to find the appropriate Kernel for Tilapia. There is a Github for Lineage OS Tilapia.

Did you try the unofficial Lineage OS for Tilapia by Charles IV? If so, did 3g work for your Tilapia?
[Nexus 7 Android Development] danja95:
3G does on both not work. only on nAOSProm-7.1.1-tilapia-b05
[Nexus 7 Android Development] tech927:
Tilapia nexus 7

Is this rom compatible with the Nexus 7 2012 Tilapia version? Firstly, I have no intention of using the 3G on this tablet and would love it if everytime I booted I didn't get the message no sim card present. Secondly, I have got twrp 3.0.2-0-tilapia.img installed and working on the tablet. I know Grouper is the Wifi only version of this tablet, but is the rom compatible?

Thanks.

Dave.

You can always flash the Grouper TWRP on your Tilapia from https://dl.twrp.me/grouper/. You will be able to use all Grouper roms on your Tilapia then. They just won't have 3g, and will be the WiFi version.

Sound manager

Hi there,

I have my nexus paired to my car stereo via bluetooth. While playing music through google play music, I noticed what sounded like compression on the audio. Also the volume was alot quieter than other devices whist paired.

So i decided to look further and found that the audio was being managed by the EQ settings in the app. I set the EQ to off and there was no change in volume.

I then opened the stock music player and opened settings, which opened the same EQ manager and set that to FLAT then 'BOOOM' it was screamiing loud!

I tried this on other devices and found the same thing happened. It looks to me that the sound EQ DSP manager app sets the EQ for that app only and not globally.

When globally accessing the EQ/DSP app, the EQ will change but it seems like compression occures and lowers the output volume.

I don't think this issue is specifically to do with crDroid.
[Nexus 7 Android Development] AICProcks!:
I have crDroid on my phone as well, and I do notice that the Bluetooth sound in car is lower quality. However, I also had this occur with other roms. For what its worth, I find AIMP player from the Play Store to work the best.

Try AIMP player, and if you experience any issues, then sign up for and try the AIMP beta player.

If AIMP player doesn't match your needs, try VLC. In my experience, I had more issues with VLC on Android, but it works as well.
[Nexus 7 Android Development] JT1510365:
Flash this fix in recovery posted here and it will fix your setup wizard having this issue the issue is open gapps does not use the right setup wizard for this ROM so in the fix is the setup wizard from beansgapps mini 7.x which works with any device or ROM having this issue its not a device issue but rather a gapps or ROM issue

[Nexus 7 Android Development] ttg:
Day 1 and this rom feels well.

I mostly use device as book reader and basic browsing with Firefox.

It does got some issues but they're minor.
[Nexus 7 Android Development] AICProcks!:
Hey, I use the same exact SmartBar settings :highfive:. Although the authors of the apps coded for the menu button to appear at various points, I will take a look at the 2 menu button bug because I didn't experience it back when I was using Resurrection Remix rom.

Regarding the attach files to XDA post, which browser are you using? I am using Atlas Browser, and I can attach files without any problems.

VLC is definitely an excellent app, but I don't use it on Grouper. I tried using it on my phone, but I couldn't seek to the next online radio stream with my car radio next button via Bluetooth. I also couldn't get "RDS" information about the current song and artist playing. With AIMP player, I could. :cool:
[Nexus 7 Android Development] AICProcks!:
You could also try going into and checking Settings> Developer options> Disable absolute volume. This sounds like it can help with the extremely loud volume that you experienced.
[Nexus 7 Android Development] JT1510365:
i am using xda app from play store
[Nexus 7 Android Development] AICProcks!:
I tried the XDA app now and experienced the same error. I resolved it by force closing the XDA app. Now it works. :D

Of course, I did this after allowing the initial storage prompt.
[Nexus 7 Android Development] Crafty77:
I've put crDroid on my Nexus 7 2012 (grouper). It seems really smooth, but I'm having problems with gapps.

Initially I didn't have enough space, even for the pico version, so I wrote a custom install file according to their wiki, I only included Core and the GooglePackageInstaller. Flashing this worked, so I deleted the user data cache and the dalvik cache and rebooted, upon rebooting I just get continual messages for the setup wizard saying that it keeps stopping, giving me the option to close the app. I've also seen the same message for the Android Play Services app. The tablet won't actually fully boot and just goes in to a loop.

Is there anything I can do or check ?

Thanks
[Nexus 7 Android Development] AICProcks!:
Did you apply the "Open Gapps System Size Fix"? Put the following file in the same location as the Open Gapps Pico file is located on your Grouper. Then, flash Open Gapps Pico through TWRP. gapps-config-grouper.txt - https://www.androidfilehost.com/?fid=745849072291693897
[Nexus 7 Android Development] Crafty77:
Yes as above, I used a custom config file, the content of which is :

Include

Core
PackageInstallerGoogle

I have the Pico gapps package, as suggested in the thread. I don't use google calendar, so left out calsync and obviously have no use for the dialler either. As far as I can gather, the Pico installer doesn't have the other items in it that are mentioned in the file you linked to nor should they be needed.

Edit: I've also just started from scratch, formatting /system, re-flashing crDroid and gapps with the file you linked to, the problem still happens when the device is rebooted. Note I cleared data cache and dalvik cache after installing and before rebooting.
[Nexus 7 Android Development] AICProcks!:
That's really unexpected since the gapps-config-grouper.txt usually helps with fitting the Open Gapps package, at least on my Grouper. Did you make sure to do the Advanced Wipe Clean of the entire device? Also, if you don't need a few system apps, you can use the following debloater zip that I made based on [MENTION=6303197]lieferant[/MENTION]'s original zip: https://www.androidfilehost.com/?fid=746010030569951230. Since I don't use the following System apps, I uninstalled them with the zip: Calendar, crDroidFileManager, crDroidMusic, Email, crDroidWallpapers, Browser, BasicDreams, LiveWallpapersPicker, AudioFX, and Jelly.

Regarding the initial Setup Wizard, did you try flashing JT1510365's Setup Wizard Fix: https://drive.google.com/file/d/1Sl3mLc9davcYZ6roVsBDPA1gdzpPxD_6/view?usp=drivesdk. You can also skip the initial Setup screen by tapping on 4 edge points on screen starting from upper left corner clockwise.
[Nexus 7 Android Development] Crafty77:
I've just tried again, from TWRP I did the following steps:

formatted system

installed crDroid

installed open-gapps

installed the setup wizard fix

factory reset

cleared dalvik cache

Still gives me the same problem, tried the nano gapps instead of the pico, no difference. I can't get to the setup to get connected to wifi as the "possible bugs" section shows.

I did a little reading and found that CM had this problem with release 13 a while ago, a couple of fixes were listed:

1) Simply delete the setupwizard apk from /system/priv-apps, this works, but play services (and android services framework) both still crash.

2) grant permission READ_PHONE_STATE to the SetupWizard, this doesn't work, just telling me that SetupWizard didn't request that permission.

When I tried number 1 it will actually boot and I can move around - I set up a wifi connection but was still getting crashes (play services & android services framework). Also, I noticed there was no play store in the app drawer..

Should I try an older crDroid version? currently using the January one.
