Hi again

Yea, Unfortunately Bluetooth is not working here after clean installation.

UPDATE:

Dirty flash to 20190516 Build, Bluetooth works like a charm!
[Nexus 7 Android Development] Weishaupt:
Thank you so much for this ROM! My 2012 wifi is working again normally, and feels like it's 3 years younger.
[Nexus 7 Android Development] MacLeod100:
Did you install the right Gapps version ?
[Nexus 7 Android Development] goran_s:
I spoke too soon. My grouper connected to phone when I tested it after the flash but it still doesn't connect to my OBD adapter or car stereo. I guess I'll flash older version too. :(
[Nexus 7 Android Development] MacLeod100:
Works here too but Bluetooth bug i can confirm

Sees my devices speaker and headphones but it doesn't connect

No more HBO GO whit JBL Bluetooth speaker :(

I notice some random crash of the launcher too
[Nexus 7 Android Development] laugeek57:

[Nexus 7 Android Development] ThatExactStraw:
First of all, thanks for the great work keeping our beloved Nexus 7 alive! I very much appreciate the effort as well as the overall minimalistic philosophy of the ROM. I have been using the March build of the ROM for some time now with no issues. I would like to report on a couple of issues encountered in the latest builds.

Several days ago, I have dirty flashed Grouper OTA-Package (Build 20190516). First, the battery drains within a day even when the tablet is not used at all (the back of the tablet is also noticeably warm as if it runs some resource-heavy app). I wanted to install a system monitor to try and track down the issue but was unable to launch PlayStore. Second, I was unable to connect the device to the PC to transfer files - it just started charging without showing the menu as if the cable did not support data transfer (tested on several cables, all of which work fine with my other android device). I then wiped everything except internal storage (which I could not back up due to lack of connection) and clean flashed the 20190823 version along with the latest Opengapps (ARM 7.1 pico). Same result - no connection to PC, high battery drain, and no PlayStore at all. I tried reflashing the Gapps and had the same result as CamoGeko in this post - PlayStore did appear but crashed upon launch. Weirdly, after this I was unable to go to Settings - it just showed the blank screen. Reboot did not help.

I will go back to the March build for now - it still does everything I need. Hope you will find this feedback helpful.
[Nexus 7 Android Development] :
I've noticed battery drain is greater than it was too. I've also noticed that my grouper seems more responsive than it was. I figured perhaps the 2 were related, though maybe not.
[Nexus 7 Android Development] arnab9385:
My Grouper restarts whenever I connect to a wifi network, otherwise the rom is extremely smooth and stable. Running the May '19 build. Thank you for giving new life to a 7 year old device!!

Hi to all,

this ROM support OTA update ? or do I have to manually update each new version?

I noticed that this has not the app Camera

Thanks
[Nexus 7 Android Development] AndDiSa:
No, currently there are no OTA updates, you need yo do it manually. The camera app is not included because it's not working with 7.1.1 on grouper.
[Nexus 7 Android Development] k ahangar:
no i didn't restore nothing.

just, is erase the system partition completely means wipe system partiton? i didn,n erase my medias and files from my tilapia. may is this a problem?
[Nexus 7 Android Development] humano:
This rom is really fast and stable but it still has many small bugs in some apps.....

- lock screen needs repeatedly swipping to get the pattern screen (9 points).

- some apps like clock closes automatically when using it normally.

can this be solved wipping some caches?
[Nexus 7 Android Development] millosr:
[MENTION=2188693]AndDiSa[/MENTION]

I have tried your latest tilapia build and I'm getting repeated rild restarts.

The reason for restart is (dmesg):

[ 95.112495] init: Service 'ril-daemon' (pid 2070) killed by signal 13

SIGPIPE probably happens because frameworks/opt/telephony disconnects from rild after this exception:

12-12 17:49:02.131 891 1004 E RILJ : Uncaught exception read length=64Exception:java.lang.ArrayIndexOutOfBoundsException: length=0; index=0
12-12 17:49:02.131 891 1004 I RILJ : (0) Disconnected from 'rild' socket

Have you applied hardware/ril patch? Without patch there is one int missing from GET_SIM_STATUS response which can cause error like this.
[Nexus 7 Android Development] AndDiSa:
[MENTION=6754437]millosr[/MENTION] thanks for your help

I thought I had applied all the patches needed, because it should be in my local repo (the patches) but I'll re-check ...?
[Nexus 7 Android Development] AndDiSa:
[MENTION=7913386]k ahangar[/MENTION] Did you wipe data? If not, it's obvious that you have FCs. You don't have to wipe media / files, but you need to wipe /data if you are not upgrading from the same ROM.
[Nexus 7 Android Development] AndDiSa:
[MENTION=929108]humano[/MENTION] imho the problem with the lockscreen is related to the doze mode / sleeping processes which need to be awaken. This behaviour you can find on almost all 7.1 ROMs. The situation regarding some apps force closing on first usage is similar. It looks to me like a race condition when art is running in background optimizing the app just started. If that process is not yet finished while you start using the app it's crashing. If you wait some time / restart the app it's running ... This behaviour is not reproduceable and it happens rarely, but it's annoying .. :(
[Nexus 7 Android Development] millosr:
I've just looked at your patches and it seems that you have updated hardware/ril patch and remove necessary change:

https://github.com/AndDiSa/platform...3904a7926e8bb77a57c37dade6/hardware_ril.patch

This is what is needed :

https://github.com/millosr/device_asus_grouper/blob/nAOSP-7.1/patch/hardware_ril.patch
[Nexus 7 Android Development] AndDiSa:
[MENTION=6754437]millosr[/MENTION] I've found the problem with the ril: during the merge of android-7.1.1_r4 the patch was lost ... will re-include it and provide a new build. Thank you again for your help.
[Nexus 7 Android Development] adstraylight:
[MENTION=2188693]AndDiSa[/MENTION], would you consider adding a level of adjustability to the kernel? Specifically a control for the Minimum/Maximum panel backlight that first originated in M-Kernel, and has subsequently been included in DC-kernel. It is accessible via Sys values of 0 to 255, or more conveniently via TricksterMod, and I'm guessing DC's performance control app.

In Trickster it is called Backlight Clamping and includes an option for range scaling, both of which are very useful for reading at night, by allowing a significantly lower level than stock.

I can use DC's boot.img with your ROM, but it would be great to have this feature available in yours to ensure compatibility.
[Nexus 7 Android Development] AndDiSa:
[MENTION=2583740]adstraylight[/MENTION] I'll have a look at it. I saw the commit from [MENTION=4948627]daniel_hk[/MENTION] and I think there shouldn't be problems in merging.
[Nexus 7 Android Development] k ahangar:
yes i wiped data and cache and system partitions before instal the rom.
[Nexus 7 Android Development] fernandoarafat:
Tilapia user here. Just installed last night, have the same issue as [MENTION=5806912]brooker88[/MENTION]. I forgot to turn airplane mode on, but the tablet was idle and WiFi was set to stay on while sleep only when charging. I do use playstore. Overnight it went from like 89 to 61 percent in around 5 hours. In the morning, I swipe/closed all the recent apps (I usually don't do this) to see if something was keeping the tablet awake, will know if that worked once I get back home. By the way, great ROM, never thought my Nexus 7 would be that fast with a 5.0+ ROM.

EDIT: Swiping recent didn't worked, it was dead when I came back from work. This night it deep sleep properly, just like 1% drain overnight. What I did this time was wiping cache and turning on airplane mode.
[Nexus 7 Android Development] manteez8:
I had a problem with Netflix with my current Custom ROM 6.0. I can't download movies from Netflix because there is no download menu available. Some people solve the problem by installing the official Android ROM.

Have anyone tried netflix app in this ROM? Can you download the movies?

Thank you :)
[Nexus 7 Android Development] AndDiSa:
[MENTION=3013557]manteez8[/MENTION] the previous versions had some problems with widevine drm. I am currently uploading a new version of the ROM where widevine is (hopefully) working.
[Nexus 7 Android Development] AndDiSa:
New build (20161213) uploaded, Tilapia issues fixed

I've uploaded a new version with some minor enhancements / fixes.

The most important: tilapia ril issues fixed (thanks to [MENTION=6754437]millosr[/MENTION])

There are some other, minor fixes / enhancements, too, but I was not really able to test all of them in depth:

camera2 fixed (thanks to [MENTION=3729448]aaopt[/MENTION])

using widevine libs from Unlegacy (thanks to [MENTION=2633638]Ziyan[/MENTION])

added missing WallpaperPicker project (due to that I had some issues when using the pixel launcher)

Add CUSTOM_BRIGHTNESS support (used the patch from DC-kernel, thanks to [MENTION=4948627]daniel_hk[/MENTION])

[Nexus 7 Android Development] Swanee123:
Same here with Tilapia. I'm very happy with most recent build
[Nexus 7 Android Development] Nexus7_tilapia:

But, What about Bluetooth?

I have issue with it;

It could find devices but File Transferring is impossible!
[Nexus 7 Android Development] Swanee123:
Just did some basic tests. Same results here. Can't transfer files with bluetooth and tilapia on latest build
[Nexus 7 Android Development] mafarric0:
So yeah, yesterday I found that the Bluetooth no longer works in this version. It detects my headphones devices, but fails to connect!
[Nexus 7 Android Development] arnab9385:
Updated to August build, WiFi issue seems to have been fixed. Am facing issues with Bluetooth file transfers - the devices pair but cannot receive files.
[Nexus 7 Android Development] gerega:
Hi, I have the following issue: everytime when I try to download something from within a browser, the download item in the upper left corner pops up and hides immediately. And the download stops at once. Doesn't matter which browser I use.

I have already checked, if the download manager app and the app download have sufficient rights, but I can't fiddle around with the rights in those two system apps.

Playstore otherwise works fine.

Any help is very welcome!
[Nexus 7 Android Development] :
My first thought - have you available disk space?

Sorry if you've already checked that and mine is a stupid remark :)

Thank you for your the response, unfortunately I cannot build myself, I tried any possible solution but my 120GB SSD is just too small and my ThinkPad is getting hotter than my microwave.. lol

For now I simply switched back to the previous build that another member contributed and it's working, I'm however willing to test anything and provide logs if needed, thanks a ton for the ongoing support! That is just incredible!:cool:
[Nexus 7 Android Development] RacerXXX:
I have two grouper Nexus 7's with Lollipop 5.1. They have been really dog slow lately. I read quite a lot of this thread. So Yesterday I decided to update to Android 7.1 Since this new I was cautious. On Windows 10 I downloaded Android Studio. Configured it for the Google USB. I used a USB cable to create a connection to the PC via USB and installed twrp-3.2.3-0-grouper. Then I wiped everything except for internal storage. Next, installed aosp_grouper-7.1.2-ota-eng-20190516.ds..zip. It took a little while and opened on the desktop. WOW! :good: What a difference in speed. I connected the usb cable to my PC and it is charging. Also I hooked pny USB flash drive and then formatted the drive and it works. When connect to my PC via usb it doesn't connect anymore. Not sure why. Next, installed open_gapps-arm-7.1-pico-20190919. Then installed Google Chrome. I tried to install Nexus 7 Camera the software is broken. But the Camera MX app works.....

Thanks

I have rebuilt my image after reverting the android_system_bt repo to commit: ee11502518307929e08fc9e24d9dd8037b86cd77 and restored my BT functionality, so I believe AndDiSa's suspicion is correct.
[Nexus 7 Android Development] Imhotheph:
can you share your image?
[Nexus 7 Android Development] js-xda:
Is it not connecting at all or only showing up as device without a drive? If it is the latter, you have to set the USB connection mode to file transfer.
[Nexus 7 Android Development] RacerXXX:
When I first installed TWRP 3.2.3-0 and the Google USB Drivers

Device manager changed Nexus 7 icon to Portable Device\ Nexus 7

At this point USB worked fine but the connection to my PC was gone (only charging) in Android 7.1

In TWRP changed Select Storage to Internal Storage. This changed Device manager back to Portable Device \Nexus7 and internal storage appears again. I also re-enabled USB developer mode

However, now with Andriod 7.1. device manager looks like this LeMobile Android Device\ Android Composite ADB Device and internal storage does not appear. Any thoughts?

TWRP wants a update, does it need an update?

Thanks for the pointer
[Nexus 7 Android Development] js-xda:
Did you check on Android 7.1 the USB connection mode on the tablet? There are no drivers required on your PC - it is about how the tablet connects depending what it is set to. You need to check settings while connected as far as I recall.

Shouldn't be related to TWRP.
[Nexus 7 Android Development] RacerXXX:
Sorry I misunderstood, It is really easy when you plug in a usb device the tablet brings up a screen asking what you want to do. I select transfer files and boom it appears in file manager, I've only been on and android 7.1 for three days and it is quite a bit improved from android 5.1 ...

Many Thanks

Trying to install the joule android app (BT 4.0 LP)

When I go to the google play store is says "Your device isn't compatible with this version"

When I check BT in settings I see the Joule device but when I click on it I get paring or passcode error and it fails to connect.

I just tried it on Nexus 9 and the Joule app works fine.
[Nexus 7 Android Development] shibadoo:
First of all thanks so much for keeping our beloved device up to date.

Since some months (I really can't tell exactly since when or since which version of this ROM) I have a problem with the battery. I charge it to 100% and then do not touch it for some days. After that it is completely empty, although it was switched off all the time. It makes no difference if I charge it when it is on, and after charging I switch it off, or if i charge it when it is switched off. Any ideas? Somehow it behaves as if it is not completely switched off, but I doubt that this really is the case ...

---------- Post added at 08:57 PM ---------- Previous post was at 08:49 PM ----------

I'd assume your battery is physically dying, it's a pretty typical sign when it cannot hold a charge anymore, luckily it's super easy to replace the battery and inexpensive too, check the web for proper guides if needed...
[Nexus 7 Android Development] ThatExactStraw:
I had the same problem with the May build (reported in this post - drains within a day and noticeably warm at all times). I don't think this is due to the dying battery - looks more like some process drains it in the idle state. I have since reverted to the March build and now it can remain on idle for several days without a noticeable drain. I should note, however, that all this was done via dirty flash. Will try to clean-flash the September build and see whether the problem will still be there.
[Nexus 7 Android Development] step5:
can't install gapps pico with this release. insufficient space (error 70)

UPDATE: it's working! had to reboot after flash and then installing gapps pico worked like a charm! thanks!
[Nexus 7 Android Development] shibadoo:
To be honest I do not think it is a dying battery. If I use the device there is no sign of a shortened lifetime. I have not really tested it with a stopwatch, but it is more or less the same battery drain if I use the device and leave it switched on or if I switch it off completely (not idle) and do not touch it.

Just to clarify: The battery drain appears when the device is completely off, not in idle state. And the battery is not empty within a day, it takes some days (I would guess a week or ten days, again I have not tested this with a stopwatch). And the device does not get warm. So my problem seems to be a different one than yours.

To be clear and sum it up once again: The battery drains completely within a few days even when the device is completely switched off.

Hi XDA Heros,

i got a problem. I have the Nexus 2012 WiFi and ****ed it up. So now i'm trying to fix it. My problem now is that i use the twrp-3.2.3-0-grouper and the aosp_grouper-7.1.2-ota-20190823.

When i try to adb sideload it it ends after a few seconds with the message "Updater process ended with signal: 11" now i don't find a solution for the problem.

Can someone help me?

Thank you

Seefuchs
[Nexus 7 Android Development] mikeataol:
If TWRP still loads, you should still be able to copy the rom to the device from your PC and try installing it that way.

(I have never tried sideloading with this device)
[Nexus 7 Android Development] paasoares:
Hi,

Don´t know exactly what you mean by "****ed it up" , but you could try this :

- turn on the device and boot it to bootloader

- connect device to your pc and do "fastboot boot twrpXXXXX" (correct version of TWRP)

- wipe everything (data, cache, system, etc)

- adb sideload aospXXXXXXXX (correct version of this rom)

This should work
[Nexus 7 Android Development] Sam Nakamura:
Well I'm sorry but I cannot think of anything other than a faulty battery, I mean you can try to flash to another build, maybe something completely different like lineageOS which could be found in our forums somewhere, just to check if it changes anything.

However the OS actually shouldn't interfere at all as your problem only happens when the device is turned off, that's why I still assume a faulty battery because in a turned off state there's nothing that could have an effect on battery itself, except it's somehow faulty and has hardware problems!

So only viable solution to me is to replace the hardware that is flawed or keep it plugged into the charger - unfortunately nothing for the community to further sort out, especially as it shouldn't be connected to this topic / build.

Good luck!
[Nexus 7 Android Development] MacLeod100:
Same problem here i notice when i didn't use the tablet ( tilapia ) for about 2 weeks

The battery is not a problem it lasts 4 - 5 hours listening to music on radio on mobile network and bluethoot speaker , last 2 - 3 hours on watching movies on mobile network and bluethoot speaker

Seems that some process is not shuting down completely
