Thanks, I found it! The English word "Display" has been translated ingeniously as "Display" in the German GUI (should be: „Schaufenster” ;) ), and the setting is called "Zum Aktivieren tippen". I successfully was able to deactivate this feature. :good:
[Nexus 7 Android Development] OlliWi:
It may be translated for the german GUI to "Anzeige" but not "Schaufenster". :D

And I know that it´s called "Zum Aktivieren tippen" because i use the german language setting too. :)
[Nexus 7 Android Development] f23coupe:
So, are you releasing another build to incorporate August patches? Thanks for the new build.
[Nexus 7 Android Development] AndDiSa:
[MENTION=6400282]f23coupe[/MENTION] I do not expect the August security patches before mid of August.

Android System WebView crashes

Since last system update the browser app Firefox Klar alias Firefox Focus does no longer work. It immediately stops with the message that Android System WebView has stopped.

I then erased data of both the app and the internal app, and as next step I reinstalled the app, but without any effect.

However, the "normal" Firefox app seems to run fine, maybe because it does not use the System WebView component.

Same problem with newly installed Dolphin browser.

Solution:

Open Google Play Store app and install Android System WebView from there. If you analyse the apps list in the system settings you will notice that the preinstalled component (version 52) has been deactivated, and a new version with different icon (version 68) has been installed.
[Nexus 7 Android Development] OlliWi:
You may use the pre-installed "WebView Browser Tester" app to check if WebView is working. In my case it´s working fine, reporting version 67.0.3396.87.

I don't know if the touchscreen is on, but mine behaved the same as yours that it launched the camera app when I swiped to unlock it from sleep. I just disabled the tap twice to wake feature, so I'll see if it disables the camera from launching at wake. Weird, indeed.
[Nexus 7 Android Development] Nexus7_tilapia:
Hi all here:)

Does our Nexus 7 1st Generetion support casting/mirroring?

Miracast?

Chromecast?

EZCast?

AnyCast?

&...

Best regards
[Nexus 7 Android Development] AndDiSa:
[MENTION=8618734]Nexus7_tilapia[/MENTION] last time I tried I had no issues to cast out of the box to a chromecast device. I sometimes had issues to cancel the cast connection using the drop down menu item but I always was able to disconnect via Google Home application.
[Nexus 7 Android Development] Nexus7_tilapia:
Dear [MENTION=2188693]AndDiSa[/MENTION] thanks for your reply.
[Nexus 7 Android Development] frankusb:
I have a random question. I installed this on my tablet this past weekend and then installed Fotoo on it and set a wake up and shut down schedule. The shutdown seems to reliably work but the wake up does not, sometimes. As a test, I set a wake up schedule a few minutes in the future, turned the screen off and it worked fine. But if I let the tablet sleep over night, Fotoo does not wake the tablet up. I don't think it's a problem with Fotoo since it woke up a Galaxy Tab 2 7.0 with the same schedule.

Any suggestions on what to look at?
[Nexus 7 Android Development] AndDiSa:
[MENTION=3771488]frankusb[/MENTION] I suppose it's related to the fact that the device is going into deep sleep mode when it is not used for a longer time period. That's also the reason why D2W is not working reliably. Als long as the processor is not in deep sleep, everything works fine, but if deep sleep mode is entered you need a special interrupt (e.g. pressing the power button) to recover from deep sleep mode.
[Nexus 7 Android Development] frankusb:
Thanks, is there a simple way to avoid deep sleep?

I am going to try this app.
[Nexus 7 Android Development] Bakica:
Maybe you can try to exclude this app from battery optimisation?
[Nexus 7 Android Development] brooker88:
Anyone know how this compares to andDisa other 6.0 ROM? I got fed up of trying nougat ROMs as they always ended up slow. However the 6.0 ROM by andDisa has been running flawlessly for the last few months, just wondered if updating was worth it or not. Thanks & keep up the good work
[Nexus 7 Android Development] frankusb:
This turned out to have nothing to do with deep sleep. The app I linked kept the screen on, dim, but on.

The root problem was a user error, when setting up a schedule in Fotoo, by default, it does not repeat. I mistakenly assumed it defaulted to repeating every day. Once I selected all the days in the schedule, it works perfectly every day so far.
[Nexus 7 Android Development] OlliWi:
Just give it a try. There was a major bug in memory handling when you had a couple of apps staying in the background task list (causing the device to run out of memory, becoming slower than the slowest of the slow devices;)). Maybe that´s what you experienced. This bug is fixed in this release.
[Nexus 7 Android Development] Ahkah:
time advances

I could only compare it to Beanstalk-6-plus-Parrotmod, and compared to that combination it behaves similarly.

BTW: Both are heavily outdated since 8.0, extremely outdated since 8.1 and ridiculously outdated with 9.0, not to speak from 10... ;)
[Nexus 7 Android Development] lotte67890:
The last one is amazing! I've never seen my tablet that fast and stable!!! @AndDiSa thank you so much!
[Nexus 7 Android Development] TureX:
Apart some lag in game and a random reboot, this rom is fantastic. Good job and many thanks [MENTION=2188693]AndDiSa[/MENTION]

You mean [MENTION=2188693]AndDiSa[/MENTION] ? :laugh:

Does anyone here know how to reorder the notifications in the notification bar?

i do not mean only the top priority which is available in Settings/Notifications.

Thanks for all the replies, will give it a shot at weekend
[Nexus 7 Android Development] WarningHPB:
I have the Nexus 7 3G (Tilapia) and I'm having an issue with the auto brightness adjustment.

When I'm in a dark room and I go to adjust the brightness to a lower setting, the screen or rather the back-light will flicker on and off while getting dimmer. If happen to let go when the back-light is off I have to shine a bright light at the light sensor to make the auto brightness adjust it self, so the back-light come's back on so I can adjust the brightness again.

I don't know if this issue is only related to my unit but thought i'd make a post and just report it.
[Nexus 7 Android Development] AndDiSa:
Version with August security fixes (2018/08/05) available

I've just uploaded the new version of the ROM (Grouper and Tilapia version) with the latest security patches found in AOSP applied to it.

While still trying to improve the overall user experience, I additionally I tried to improve the startup behaviour, especially when waking up the device from sleep / launching a new application.

You can download the

Grouper OTA-Package (Build 20180809)

or

Tilapia OTA-Package (Build 20180809)

from here or from the OP
[Nexus 7 Android Development] shaggyskunk:
Your tireless dedication to this 6 year old device is to be admired & appreciated! ??
[Nexus 7 Android Development] JJworx:
I installed the previous version (07_30?) as an update, but mistakenly reinstalled Magisk instead of pico Gapps afterwards. Now the system app "...UI" with the capital N as icon is causing wakelock, draining the battery. Repeating installation correctly doesn't help. What can I do?
[Nexus 7 Android Development] AndDiSa:
[MENTION=5880039]JJworx[/MENTION] I do not understand you fully ... you updated thr ROM and started it without having flashed GAPPS again? In that case it's best to re-install the latest backup and do the update again because there is a chnace that you lost the user specific Google settings which might also cause Gapps to force close
[Nexus 7 Android Development] JJworx:
No problems with Gapps as I already reinstalled correctly. But since the wrong install the battery is drained in 7h, because the device never sleeps. "Akku" shows Android OS as cause, "Wakelock Detector" identifies "... UI" (the system app with the green N as icon; sorry, I don't have it here right now) as the culprit. What to do?
[Nexus 7 Android Development] AndDiSa:
I think it's the systemUI process which running with Google permissions, too. Did you already try to reboot? Did you have a look at the log file?
[Nexus 7 Android Development] JJworx:
Reboot, yes, I tried. Where's the log file?
[Nexus 7 Android Development] TureX:
Hi, i have updated from 30/07 and now cannot login play store
[Nexus 7 Android Development] AndDiSa:
[MENTION=3777227]TureX[/MENTION] did you reflash Gapps?
[Nexus 7 Android Development] TureX:
Yes, reflashed and i perform a cache and dalvik wipes as suggested
[Nexus 7 Android Development] Sam Nakamura:
Just flashed the update with TWRP 3.2.3 by:

-flashing ROM, then reboot to recovery,

-then flashing GApps & Magisk,

-wipe dalvik/ART cache and Cache

-and reboot to system

All fine and working smoothly, user experience improved dramatically the last updates - great job!
[Nexus 7 Android Development] TureX:
So i must flash with 3.2.3 twrp?
[Nexus 7 Android Development] nick88:
Not necessarily... 3.2.2 works also fine
[Nexus 7 Android Development] TureX:
Solved:

1)flash ROM reboot system

2)flash gapps ,do wipe cache and dalvik

3)enjoy

Thank you for this smootly rom
[Nexus 7 Android Development] k ahangar:
hi [MENTION=2188693]AndDiSa[/MENTION]

tnx for your roms

Do you not make Android 8 for this device?
[Nexus 7 Android Development] Nexus7_tilapia:
Dear [MENTION=2188693]AndDiSa[/MENTION]

May i ask you what do you mean by "zRAM size for Tilapia corrected" ?

I see my tilapia faster than before, does it relate to this correction?

BEST REGARDS
[Nexus 7 Android Development] AndDiSa:
[MENTION=8618734]Nexus7_tilapia[/MENTION] zRAM is increased to 350MB for Tilapia, too. The last build had already this modification for Grouper, but I forgot to add this change to the Tilapia tree. Now Grouper and Tilapia are at the same page.
[Nexus 7 Android Development] SGH-i200:
So true! I feel like we all should donate something to where [MENTION=2188693]AndDiSa[/MENTION] wants us to, to manifest our appreciation! :good:
[Nexus 7 Android Development] pauldrudd:
I've just updated to the latest release and it is amazingly smooth for an old device! Thank you so much! Would anyone advise on using lspeed to squeeze extra performance or battery life?

Also how about xposed framework plus amplify, powernap, greenify and servicely for battery? I don't know if the hardware and ram can handle all of these, or if I should just leave it as the great dev intended. Apologies if this is a noob question, just wanted to know if anyone has an opinion on this. Thanks again!
[Nexus 7 Android Development] topoldo:
Just to say I tried to install the August update without reflashing GApps. Unfortunately the tablet stuck on the "android" animation so I had to reinstall everything and I took this occasion also to upgrade to TWRP 3.2.3. This way everything is ok again.

Tnx again AnDiSa for maintaining this device I use as my car navigator
[Nexus 7 Android Development] shaggyskunk:
Just a tip - Most Devs have a strong dislike for Xposed as it's known to cause all kinds of issues & it's very difficult to diagnose - Just sayin' ? ?

I won.
[Nexus 7 Android Development] OlliWi:
You didn´t. Same version here after last week´s update. ;)
[Nexus 7 Android Development] Portgas D. Ace:
All those battery tweaks you might get from one of the popular battery saving threads here on XDA are somewhat outdated. Since Android Nougat, there is no need for Amplify/Servicely/Powernap anymore (especially Powernap is known to cause more harm than good). I was one of those hardcore battery saving monks by myself, but after updating to Android Nougat, I found out that Android itself in combination with Greenify alone does a better job than Xposed and all the other stuff combined. So my advice: if you don't need Xposed for anything else, drop it and go with Greenify to hibernate apps that you rarely use.
[Nexus 7 Android Development] koenichlich:
I just rediscovered my Nexus 7 3G (Tilapia) in a closet in my office - running a Android 5 based Carbon ROM.

I'm glad I found this ROM being pretty much up to date. Thanks so much! It's running great.

Just a little remark: I'd find it useful if the very first post could be adjusted a little for Tilapia users: The Tilapia-specific TWRP is needed for installation. The link leads to the grouper variant only at this time.
[Nexus 7 Android Development] SGH-i200:

[Nexus 7 Android Development] siniranji:
Too fast, blazing speed, My Nexus 7 functions with out any lag or stuttering, even i dropped my plan to buy a new tablet, and this initiative of extending the technical life of Nexus 7 grouper is highly commendable, sure the OEMs envy your initiative, but the amount of satisfaction you are getting is awesome, citations to follow, Great Work
[Nexus 7 Android Development] Johan132:
[MENTION=2188693]AndDiSa[/MENTION] thanks for making this ROM available! I was about to look for a way to donate, and a contribution to Doctors without Borders sounds like a great idea; will do!
[Nexus 7 Android Development] Johan132:
With Nougat, is there really a benefit of regularly trimming the /data and /flash filesystems manually? AFAIK trimming is scheduled automatically? Or is that not supported with the older generation flash in the Nexus 7? Of course I googled for info, but there's lots of conflicting information.

Thanks!
[Nexus 7 Android Development] AndDiSa:
No need to trim manually, trim is executed 2 to 3 times a week which should be sufficient unless you are writing and deleting many files continuesly.
[Nexus 7 Android Development] section_94:
Back to the January build yet again...Sadly for my tilapia the situation has been like this since February when I first installed this ROM:

1) See a new version uploaded

2) Get excited that it might work for tilapia this time

3) Random crashes/reboots when wifi is on again...

4) Back to the January build

Its a real shame cause the new versions are much faster\smoother but nothing seems to be stable for me ever since the January build. And I have tried virtually everything to get them to work by now.
[Nexus 7 Android Development] Sam Nakamura:
Providing logs would be immensely helpful and much more effective, no one can debug issues by a description alone, also much details about your instalation are missing (if GApps which exact version, Magisk and if what version and what modules, any other mods, what's your process for flashing the ROM)...
[Nexus 7 Android Development] Ahkah:
I have an ordinary Grouper, in fact two of these, and both run satisfactorily with the August version. The device cannot handle many apps simultaneously, and it takes some time after installation until the CPUs come to rest, but nevertheless it's quite usable. However I recommend using light weighted apps, e.g. Newpipe instead of Youtube, etc..

#Report

Hi guy

my tilapia works like a charm especially after setting zRAM to 350MB by

sir [MENTION=2188693]AndDiSa[/MENTION] in the latest build.

Gapps: Pico

Magisk: v16.7

TWRP: 3.2.3.0

Build: 20180809

Dear [MENTION=2188693]AndDiSa[/MENTION], Thank you sooooooo much
[Nexus 7 Android Development] OlliWi:
1. Upload logfile

2. Dou you use 3G on tilapia?

3. Disable IPv6 on your Wifi router and check if the problem persists.

4. There is no need to re-flash the entire zip, you can flash the january kernel (boot.img) using fastboot and still use the august android system (with all the android security patches).

There may be still some room for performance improvements on tilapia devices.

A couple of days ago I found out, that the init.grouper.rc file is broken in all tilapia builds and some "tuning" parameters for IO scheduler, low memory killer and virtual machine settings are not applied at all. I´m currently figuring out what each of these parameters does (by reading all those kernel documentations) and once I found the "optimal" parameters, they will be included in the next release.
[Nexus 7 Android Development] :
I'm getting random crashes with the new grouper update. Always web browsing related, different sites and different browsers. I've restored back to the July update for now (which was rock solid for me)

I went through the same update process as usual; factory reset, load rom, boot, load supersu, boot, load pico gapps, boot, restore my user apps (I've found a dirty flash gives uncertain results)

I'll try it the update again later, maybe replacing my app restore by downloading from the market.
[Nexus 7 Android Development] Portgas D. Ace:
Did you try the following installation process?

1. Wipe /system, /data, /cache, /dalvik (clean flash)

2. Install ROM, install GApps

3. Reboot

4. Boot into recovery

5. Flash Magisk

6. Reboot
[Nexus 7 Android Development] OlliWi:
There is no need for factory reset when you upgrade from a previous version of this ROM.

You also don´t need to restore your apps.

Just boot into recovery, flash zip, reboot into recovery, flash gapps, then reboot system for the first time

without root

!

Then boot into recovery and install supersu or magisk to root the device.

This procedure always worked for me. I never had to restore any apps.
[Nexus 7 Android Development] Johan132:
Quick update; I have run with /data and /cache formatted as F2FS for a few days, but I have returned to EXT4 this morning.

In practice, I had the impression that booting / restarting took longer with F2FS, and otherwise I didn't notice any performance improvements. Neither did Antutu Benchmarks (FWIW) when I measured; F2FS averaged to 20810 (three measurements), while EXT4 averaged to 20560.

Not worth the bother for me really, though I can imagine the difference would have been greater with older Android versions (Nougat runs surprisingly well on older devices, like the Samsung S3 and our Nexus 7).
[Nexus 7 Android Development] StevePritchard:
Hi,

I think this question has been asked before, but it was some time ago...

I've just managed to get the latest ROM working on my Grouper (I flashed the recovery, ROM, and Pico GApps, and nothing else), however the "Sky Q" app won't run because it thinks the device is rooted.

Is there a way to ensure that the device is unrooted?

Cheers,

Steve.
[Nexus 7 Android Development] AndDiSa:
[MENTION=272153]StevePritchard[/MENTION] there is no root included within the ROM, so root check should should always fail. SafetyNet check is green for me ... even with Magisk installed. Sorry, but I do not know how "Sky Q" is checking for root.
[Nexus 7 Android Development] StevePritchard:
I think it's really picky. Could it be the unlocked bootloader? Can that be re-locked?
[Nexus 7 Android Development] pincher65:
at me too Gapps weren't installing ( twrp 3.0.2, full wipe, SuperSU R05 flash after , error messages during the installation wasn't). the repeated installation gapps has solved a problem

ROM work nice, once again thanks for him
[Nexus 7 Android Development] Sir-Shadow:
I see you guys having problem with installing this rom. I solved mine by

1- Clean flash of ROM

2- Booting ROM

3- Finally flashing the GApps

I rooted mine by Magisk + pph superUser (No problem with any root app)

Cache and Data partitions are formatted in F2Fs
[Nexus 7 Android Development] mafarric0:
Hi guys,

To everyone reading this I just want to say this is a great ROM. Sometimes I get an occasional FC, but other than that everything works fine. Most of all, it's faster and stabler than the other ROM's I've tried.

By the way, all partitions in my Tilapia are in EXT4.

Keep up the good work :good:
[Nexus 7 Android Development] ski522:
2nd that...thought my N7 had finally died as it was recently locking up quit often requiring a long press of the power button...even started locking after a fresh flash of Google's own stock ROM and without a single app installed.

So I took one last gasp before looking at getting a new tablet and gave this ROM a try this past weekend...haven't had a problem since :) and the tablet is very fast and smooth now even with the majority of my apps back on it!
[Nexus 7 Android Development] oogiesfaded:
Almost tossed this tablet until I flashed this rom. So far its WAY better then before. Thanks !
[Nexus 7 Android Development] brooker88:
Hi, I'd just like to say great rom. Screen on time is great while using it. Ive noticed 2 times now though when I've turned aeroplane mode on and left idle battery fully drains. Not sure what percent it was first time but second time was left at %70 and within 10 hours was fully drained(wouldn't boot without charging) haven't used a battery monitor so not sure what cause is but I'll check next time. Android system had been awake for over 13 hour though. I don't use playstore so won't be anything Google related. Anyone had similar problem?

Edit: Didn't happen this time overnight, only dropped %1
[Nexus 7 Android Development] ski522:
The only issue I haven't been able to figure out yet is the speech to text option. I installed google's keyboard as I like to swipe, but hitting the microphone does nothing. Do I need to install something else from the Play store to get speech to text option?
[Nexus 7 Android Development] Troublicious:
Hi AndDiSa, one question: do you think it is possible to include WideVine drm in this rom? I use an app (molotov.tv) which can't be used without it :(

Thank you for your response
[Nexus 7 Android Development] AndDiSa:
[MENTION=2976373]Troublicious[/MENTION] There are still some problems with initializing libwmvdrm.so, but I am looking at it
[Nexus 7 Android Development] Troublicious:
Yes excellent news ! I hope you'll find a solution. By the way thank you for all your efforts (=
[Nexus 7 Android Development] adstraylight:
Did you see that the 3.4 kernel (unlegacy) guys have made an open source libnvos to try to fix the FCs?
[Nexus 7 Android Development] AndDiSa:
Yes, I noticed that ... but really speaking the FCs on my tablet have already much reduced. They are happening from time to time when initialization of a view is not yet finished but you are already selecting an element on that view. Nevertheless I'll have a look at libnvos and probably integrate it ...
[Nexus 7 Android Development] adstraylight:
Glad you've pinned down the problem, it only happens to me now when a news app with many entries has just started, and because the list goes off the screen by a long way, it's impossible to tell when it has completely loaded. I'd have thought that such apps would dynamically load their content (if that's the right was of putting it) as you scroll, but maybe this would tax the system too much.

Might increasing the read ahead help?

Edit: just found a setting in Play Newsstand to disable the data saver, and counter intuitively it starts and loads much quicker now. Must be the server lag caused by bouncing each feed via Google for compression.
[Nexus 7 Android Development] AndDiSa:
I've uploaded a new version of the ROM for Grouper and Tilapia bases on Android 7.1.1_r4, you can find the download links in the OP.

Major changes:

- music app working

- improved stability (during my tests I didn't have any FC)

- kernel security fixes

Installation / updating instructions can be found in the OP.

Regarding Tilapia: As I do not have a test device available, I was not able to test. Please report if you find any issues.
