Hi guys, strange problem here: everyzime when I try to download a file with Firefox I get a download error. The files can't be saved. Of course, I have set the storage permission correctly! Any idea what's going on and how to fix thid?
[Nexus 7 Android Development] Aker666:
It's a bug in Firefox, try to update to the lastest version or use Firefox Focus. In the Nightly version you shouldn't have that problem as it has been fixed, I don't know about the Beta or the Final version.

Very impressive build. So far everything is working well. Question? What is needed to over clock Nexus 7 2012 with this build?
[Nexus 7 Android Development] Sam Nakamura:
For me the attempts to increase performance always ended in massive instabilities, I figured that this ROM already applies best settings for stability and performance BUT you can try your luck by searching this thread by keywords like "overclock", "kernel adiutor" or similar...

A interesting post showed up here:

https://xdaforums.com/nexus-7/development/rom-android-7-aosp-grouper-t3467514/post78487626

Just keep in mind that the attached kernel is pretty old by now, you lose around 2 years of patches if it even still works at all...

Good luck!

Hi, I just installed and formatted my system, data, and cache partitions all as f2fs. Noticed after the rom flash that my system partition was back to an ext4 fs. Does the system partition have to be ext4?
[Nexus 7 Android Development] AndDiSa:
Yes, system is always ext4 and will be converted to ext4 if it is formatted in a different way.
[Nexus 7 Android Development] Sam Nakamura:
Also system partition is read only, hence f2fs wouldn't make any sense as it only offers advantages to read/write partitions...
[Nexus 7 Android Development] johndaog:
I feel the device runs better and starts up faster completely formatted in ext4. Correct me if I'm ROM but I thinks its better just typing "yes" into simple format. Then installing Andisa's ROM

ISSUE

not boot on batteryless device

I trying to make N7 as carpc

All work fine except booting witout battery (battery removed and power sets to ++ and -- pins from DC-DC)

When i try to Power on I get: Google logo - long time wait - screen off - Google logo - twrp recovery

I think its kernel issues

i try kernel from this rom https://xdaforums.com/nexus-7/orig-development/wip-linux-tegra-nv-3-4-bringup-t3128195

Can you help me?
[Nexus 7 Android Development] Magmar100:

[Nexus 7 Android Development] AndDiSa:
[MENTION=530607]Dreamer...[/MENTION] I doubt the kernel from https://xdaforums.com/nex...ingup-t3128195 will work with the ROM as it is based on the Linux 3.4 branch.

Regading the boot issue itself I think the problem might be caused by the fact that the device on startup is demanding much power, more than the normal charger is able to provide (>= 1500mA).

Did you have a look at this thread? Here is an overall discussion about this.

Edit: I noticed you know the thread already ;)

[MENTION=2188693]AndDiSa[/MENTION]

Thanks for answering!

I take controller from battery and set it between DC and tablet. All boots fine!

But I have one issue – some apps can't start when launched in landscape.

example:

N7 in portrait - launch Navitel - it's launching and works fine. I can turn tablet to landscape and app rotating too.

N7 in landscape - launch Navitel - it's launching and crash

Also this issue with yandex navigation.

Hi, thanks for the fix! it works.

I just want to clarify if it stays after factory reset or it needs to be re-run?

After a long long long wait my beloved Grouper is working again :D

When I first replaced the screen it was booting but no video at all.

I finally replaced a small data cable that links the digitizer with the motherboard and boom!

Display is working!

By the way I am getting some annoying ghost touches that are disappearing while keeping the tablet on charge :confused:

Any hint?

Edit: after a while the display settled and I have no more ghost touches.
[Nexus 7 Android Development] TureX:
HI! I think you need to reapply the fix after a factory reset, but I'm not sure. Maybe the only way to fix permanently is set on source as I did on my lineageos build.

Yeah i did try in between and it needs to be re-applied after Factory reset - this is a bit problem how to explain it to basic user and remember it . If they have no clue what is recovery...etc.

limit battery charge

First a big thank you for all the work and time put in to make this ROM possible..!

With this ROM; does anyone know if its possible to limit the battery charging to ~80% via an rooted app or a kernel modification? If not possible with this ROM, is there another that has this functionality built-in?

I'm thinking about using the tablet in a static location where it will perpetually charge. If possible, I would like to prevent battery expansion and extend the life of the battery/tablet...

Among Us

First many many thanks AndDisa for keeping this golden oldie going!

My son and I have been enjoying using it to play a games on it like Minecraft, watching youtube and general browsing. He recently heard of the Amoung Us game, so we went to try it but unfortunately it loads up the first screen then pauses for about 30 seconds then flashes back to the homescreen instead of the title screen.

I have been using this rom for a few years updating it every now and then, mostly with a dirty flash. It was running on a clean install from a release from a few months ago (maybe around March) but seemed ever so slightly sluggish possibly due to changing to f2fs whilst restoring most of the apps and data with Titanium backup. I have been using the Trim app probably since rooting it way back few years so I don't think this was the cause of the lagginess.

Among Us again didn't work after a dirty update to the latest Sept version. So I wiped every partition and changed them all back to ext4, rebooted twrp recovery, installed Sept's rom, rebooted recovery, installed open gapps, wiped cache, rebooted system, initial setup, rebooted, then loaded Among Us, rebooted recovery, installed magisk, wiped cache, rebooted system, tried Among Us, Ran Trim, tried Among us again. Sadly it did the same thing with going back to the homescreen, maybe slightly faster this time though.

I went to see what GPU settings are in the developer options but I couldn't see anything that would make a difference. The other few games we play, apart from a little slow loading (which is expected for this said golden oldie), works alright once loaded.

Keep up the good work!

[MENTION=3530008]ufa[/MENTION] what options do you find below

Settings/Security

I do find there an option 'encrypt device'. Don't you have that? I didn't try to encrypt yet, but the option is there. Other people reported that it takes long time / was blocked on the starting screen. In that cases a logcat would be very helpful.
[Nexus 7 Android Development] ufa:
Yes, there's this option but if you try to do it, it won't boot anymore. It will say that your data is corrupted and needs formating. Had to reinstall stuff afterwards.

Maybe a nougat bug, because this happened in another 7.1 ROM I tried.

"all apps" screen looks ancient, unlocking problem

I noticed the same problem with the lock screen, although I neither use a test pattern nor a PIN. I have to swipe three or even more times until the device is unlocked. Maybe I am going to whip the cache to get the problem solved...

However, I found the "all apps" screen looking somewhat ancient, like some very, very old Android version. Is that normal? I am used to Android 6 (Beanstalk and Nexus), and that looked very different.
[Nexus 7 Android Development] robgriff:
I had the same problem on my grouper with this ROM but I recently changed to.the 7.1.1 from Millosr because he has introduced an updated version of launcher 3 to look like the pixel one and I have never really been a fan of the Google Now launcher and since changing to his ROM my screen swiping is fine so I wonder if the problem is with the Google Now launcher?
[Nexus 7 Android Development] robgriff:
I guess if the app drawer looks pants then you must be on the standard launcher so I don't know if the swipe problem is what I thought but to make it look better you could try the Google Now launcher which definitely has a better looking app drawer

[Nexus 7 Android Development] adstraylight:
I preface this by saying that I'm not a developer, so this is just an observation that may or may not have any relevance..

The other day I realised that my two apps that suffer webview type crashes had been running smoothly for quite some time. I then discovered that I'd somehow managed to disable two of my CPU cores in trickster. When I then restored all four cores to active service, the apps (Play Newstand & reddit), went back to occasionally crashing. I'm now back to 2 cores, and virtually no crashes.

This got me thinking about the threading of webview within the apps, as I'd previously noted that the crashes increased when setting webview to run on its own thread in dev options.

So my conjecture is that it might be possible that restricting the number of active cores, restricts the available options for parallel processing, and perhaps that when a crash occurs it's due to webview getting out of sync with the app in question.

As I say, I've no serious evidence for this......

As a footnote, I can say that I've not noticed any performance drop off by running on 2 cores, but my battery is definitely lasting longer, YMMV....

A few problems

I'm using a grouper tablet. I was using a PureNexus 6.0 ROM with ParrotMod before flashing this one. I flashed the ROM cleanly and have Pico GApps and SuperSu 2.79 systemless running correctly. I'm using f2fs cache and data.

It boots much faster and feels faster for awhile than 6.0. I'm having a few problems though and hoping someone can help troubleshoot...

1. I use a stylus and after using the tablet for more than 10 minutes or so, it starts to lag a little and the stylus takes multiple taps to confirm and starts zooming a page instead of scrolling. I use to have this problem pre 6.0, but ParrotMod on 6.0 fixed it. It's like the tablet lags more the longer it's being used.

2. I'm getting occasional app crashes, especially Google apps like Chrome and Drive. The settings panel sometimes crashes too. Also some weirdness in apps such as Drive not showing some files that I know for sure on my Drive.

3. I often have to slide the lock screen multiple times to unlock the tablet.

Any recommended fixes for these issues, or is 7.1 just buggy with grouper right now?
[Nexus 7 Android Development] adstraylight:
So it's a gapps problem? I hope it's as 'simple' as that, updated to the suggested edition (2016/12/15 - pico) late last night, reset to 4 cores, and haven't had a crash since ?

storage partition status fails after OTA update

Hello AndDisa,

Thanks for this great ROM! I have been using it with great pleasure.

I need some help now with an error I get while flashing the latest ROM. I could not make a NAndroid backup of data, so I may have to start all over.

After flashing as instructed TWRP is unable to update partition details and can not open a file named DeviceStateSyncManager.xml located on storage in /data/data/com.google.android.gms/shared_prefs/com.google.android.gms.auth.authzen.cryptauth/

Is there anyway to fix this without wiping data?
[Nexus 7 Android Development] AndDiSa:
First make sure you are on the latest TWRP.

Secondly make sure your file system on /data is not corrupted, probably you could run fsck on the /data partition to make sure everything is fine.

If you have checked this flashing should run smoothly. The problem with updating partition details is happening to me, too, but does not have any effects ... The error message you got I suppose you are flashing gapps in that step. To solve this problem it might help to reboot into recovery after flashing the ROM and before flashing gapps.

[Nexus 7 Android Development] fsw_informatrix:
Exactly the same here :D

I'm using TWRP 3.4.0 for a while and everything is working fine.

I've just noticed that you really need to reboot between each step even more than with previous version, or it will throw at you some errors I've never had before.

Yesterday, I wiped before everything but Boot, Data and Internal Storage and it gave me an error 7 when I tried to flash the ROM directly. I had to reboot to recovery and then, flashing was OK!

I suppose it is because I wiped System too...
[Nexus 7 Android Development] fsw_informatrix:
[MENTION=2188693]AndDiSa[/MENTION]: I could test a bit more thoroughly (and quicker this time ;)) your fresh November build and I'm happy to report that:

- every single of my 25 installed Apps are working as they are supposed to, also the few ones needing root, like Titanium Backup or the Official TWRP App.

- for root, I'm using Magisk 20.4 and it's doing it's job fine.

- right after the fresh flash, I failed the SafetyNet test, even if MagiskHide was activated. I needed to go to the Settings of Magisk, put MagiskHide on "off" then back to "on", for finally pass again successfully the test.

- Wi-Fi is working good and stable (20 MB down and 10 up in the same room as the router with WPA2-PSK-CCMP/ESS).

- Location works, but as I only switch it on for apps like Wifi Analyzer that need it, I can't say if it's precise enough not to drive you in a wall or a river ;)

- Bluetooth transfers files in both directions (send and receive) with a Linux laptop. As I don't own any BT headset, speakers or even keyboard, I couldn't test that, someone else will have to...

- USB-OTG works in both directions (read and write), with the included file manager and with Solid Explorer. Media files can be played well directly, without needing to copy them first on the tablet.

- XDA app and AdAway are working as intended.

- YouTube (PlayStore version) and even Netflix are working as intended.

There is a little bit of stuff showing up in the logs with level "warn" and "errors", but nothing that I haven't already seen for months and nothing hurting the daily usage, as you can see the results of my tests.

Nevertheless, I will try to get some new logs with AdAway desactivated and the original "host" file restored, just to be sure, and will post these few things here, so you can tell us what you think of those...

So, thank you again for your great job and stay safe.

Among Us

Excuse me, could you tell me if Among Us works on your tablet? I have updated to the latest version of the rom and the app but no luck unfortunately. Minecraft works, so I do not think there is anything wrong with the gpu, but I would like to rule out if it is something else hardware related. Thank you kindly.
[Nexus 7 Android Development] fsw_informatrix:
So I did try for you and I don't have good news :( :

- I can download and install Among Us from the PlayStore without warnings or problems.

- when I start it, it makes the tablet go into landscape mode and I can see the company's name and logo (both are funny, btw).

- but after that, the screen stays black for a while, until I see very briefly a white rectangle on the left side (the size of a quarter or a third of the width of the screen) and then, it crash back to the Home screen!

So no, if you see that too, it's not your hardware, but something with the game...

You say that you can play Minecraft, I could play GTA Vice City and GTA III too, all of those are old games now, so I suppose that Among Us needs some new technology like codecs, API, OpenGL version, whatever, that our old hardware isn't able to provide.

You can still try to dig within the logs with an app like CatLog, for exemple, to see if you find the culprit.

Sorry man, but it seems that you have to find something else to game on your Nexus 7...
[Nexus 7 Android Development] Ad4m5on:

Hey guys.

Does anybody have speed issues? It feels like im running a wrong setting of some sort because i just tried to instll the new update from scratch with TWRP 3.4.0.0 and everything, but my grouper unit still uses like 15-20min to even open an app. I dont get why it is so slow.. I tried to use F2FS on cache and data partition but no difference at all.

It uses like 2-3 min to unlock screen and so on. Does anyone know what could be wrong? Partition sizes or is it because of the Gapp pico package?
[Nexus 7 Android Development] andynroid:
Did you format ur data by typing yes in TWRP
[Nexus 7 Android Development] emregezgin:
Yes I did.

I have for some times played around with custom rom on older devices like oneplus one, different Samsung's and so on. That's why I'm pretty confused about how this tablet is acting like this.

It seems like the device is like pretty useless when I put on gapp, but from what I can read in peoples comments it's not the case.

I'm mainly planing to use the device as an alarm clock with google assistant and few things like calender and so on, but it can barely do this.

Do I need to increase a partition size? Or is this just a side affect of gapp?

Can someone maybe upload a video where they kind of show how fast the device is in general?
