[Nexus 7 Android Development] AndDiSa:
I am currently preparing an alpha version. There are some modifications needed to the kernel and the device tree. Some days ago I got the kernel booting and had a first check. Now I need to wipe out some issues and then probably I can provide with an alpha version. Unfortunately I do not have as much time as I would like to have, so things will take a bit ... :)
[Nexus 7 Android Development] AndDiSa:
First 7.0 version available!

I've created a first version based on Android N. To keep this thread clean, I would like to redirect all discussions to Android 7 AOSP on Grouper
[Nexus 7 Android Development] syndicatedragon:
If I have 20160808 installed, do I need to do anything special to update to 20160908? Just flash the boot and system images?
[Nexus 7 Android Development] AndDiSa:
No, nothing special, but do not forget to re-flash gapps because they are not backed up when updating the ROM.
[Nexus 7 Android Development] RampantParanoia:
I've run across an interesting issue related to freezing.

I noticed it first when playing Clash Royale that my device had frozen. It resumed about 2 minutes later.

I noticed it again while just browsing the app drawer with no other applications open.

For now, I've forced GPU rendering, and it seems to have alleviated the problem...though I haven't tried playing for extended periods of time yet. Has anyone else encountered this? What's the best way to run games on the N7 with this ROM?
[Nexus 7 Android Development] ka_ru:
Hooray.

I have a BUILD with success. :)

question to PROFI. HOW How to make Recovery ZIP out "OUT directory"?

CM make Recovery ZIP self.

Thank you

André.

forgot "make otapackage"
[Nexus 7 Android Development] mikedomo:
Reserved, works great.
[Nexus 7 Android Development] scruffy1:
excellent rom in terms of installation after the 6.0 version :eek: my sincere thanks for your fine work

my only weirdness thus far after seconds of playing, is that the volume output adjustment on bluetooth is not effective - although the stock 6.0.1 rom on my nexus 7 2013 has the same inadequacy

is that a feature ? :rolleyes:
[Nexus 7 Android Development] pprw:
Is there a way to add more than one user account? The multi accounts seems to be disabled by default.
[Nexus 7 Android Development] JALACB:
This rom runs smooth like a charm!! :good:

Is there any k-exec kernel to use as primary rom in multiboot ?

Will it maintain the optimizations for low memory device?

Thanks
[Nexus 7 Android Development] kc8sbv:
I think my N7 Grouper is bricked

I installed Ubuntu 13.04 yesterday, waste of time, by doing this

fastboot erase boot

fastboot erase userdata

fastboot flash boot /path/to/*.bootimg

fastboot flash userdata /path/to/*.img

It worked, but when trying AOSP, it would not boot. Can someone tell me what went wrong?
[Nexus 7 Android Development] AndDiSa:
It's not bricked, a Grouper device is not so easy to brick ... ;)

You need to flash boot and system, instead of userdata. I suppose the boot image you flashed is not compatible to the system still installed on the device. Restart into bootloader and restart over ...
[Nexus 7 Android Development] kc8sbv:
I have AOSP files, I can try that tonight, but I do want to move to your version. I can start by flashing TWRP to recovery and they use your instructions on the first post? Thanks for the quick replies!! :)
[Nexus 7 Android Development] AndDiSa:
Boot into bootloader, flash twrp recovery, then the ota file, gapps,... then wipe and reboot. That should work.
[Nexus 7 Android Development] kc8sbv:
What is wipe and reboot? Sounds like erasing all , and then trying to reboot. I am still too noob....

wait, that means factory reset in TWRP?
[Nexus 7 Android Development] AndDiSa:
Yes, erase everything of data and cache (but by flashing userdata.img you've already done that ...)

Factory Reset == Wipe
[Nexus 7 Android Development] kc8sbv:
I also read about

fastboot erase system -w

which seems to be, erase the whole SD card, so we can start fresh. That sounds inviting. I can flash the necessary packages, and have a clean system. Seems like the way to go.
[Nexus 7 Android Development] AndDiSa:
Normally when you are flashing system it will be erased before. The -w is for erasing / wiping the data partition, i.e. wipe / factory reset ... :)
[Nexus 7 Android Development] kc8sbv:
I flashed AOSP to my N7, SUCCESS! It boots! I'm going to d/l the zip files from this thread, copy them to the top of my SD card, and use TWRP to install them. I couldn't abd push them, Ubuntu and abd would not detect the N7.

Thanks for the help AndDiSa!!
[Nexus 7 Android Development] kc8sbv:
AndDiSa, thanks for maintaining Nexus 7 Android OS, I have your latest 6 version installed and it works fantastic. I was able to copy the files to the N7 from Windows, and use TWRP to install them, and it worked flawlessly. Again, a big thanks!!
[Nexus 7 Android Development] EternalSeekerX:
Hey I installed this on my aging Nexus 7 and it still has slow down issues and hangs as well. I am wondering if this is due to the aging old hardware or specifically due to MM being more feature rich? I am using a nova launcher as well. Maybe its my apps? I even have an interactive governor set to? I know you release stable roms so maybe its just my dying hardware?
[Nexus 7 Android Development] AndDiSa:
I suppose the slowlyness off the device is more related to the apps you are having installed / running. In addition there are devices which do suffer much when you have less than 4GB free of space. I can notice that on my device, too. As soon ad there is fewer available space it starts to lag.
[Nexus 7 Android Development] EternalSeekerX:
Interesting because i I have only used 12 out of 32 gb? These apps run fine from my really old galaxy nexus to my current s7 edge. Is it possible its something else? Should I do another factory reset?
[Nexus 7 Android Development] AndDiSa:
I guess you flashed a wrong userdata.img or formatted the /data partition with a wrong size (or your partition table is corrupt, but this is very unlikely) and now your data partition is only about 12GB.

I know there is a thread here in the Nexus 7 section which describes how to solve that issue but I don't have a link at hand.
[Nexus 7 Android Development] AndDiSa:
Edit: I read wrong. If you have still 20 GB free try to use a trim on that partition.
[Nexus 7 Android Development] EternalSeekerX:
To clarify I am only taking 12GB of space, I have access to the full 32 GB! I followed all your steps! I don't want to derail the thread so I'll try to do some digging on speeding it up. Clearing cache works but its very inconvenient to need to boot TWRP to do so! I just wanted to know if you have these lag spike issues?
[Nexus 7 Android Development] AndDiSa:
I understood you in a wrong way, try to trim your space using e.g.trimmer.
[Nexus 7 Android Development] EternalSeekerX:
So like fstrim? I'll download that and see!
[Nexus 7 Android Development] gavster26:
hi i have a problem i am only seeing 6gb out of 16gb storage i dont know what has happend and device has really slowd down. This is my first device out side the xperia range
[Nexus 7 Android Development] DevoidOfThought:
Hi! I'm trying to reclaim my previous unusable Nexus7(2012) but I've run into some problems - I installed TWRP, did a factory reset wipe. But when I try to install the OTA (20160908) I'm getting the error 'system partition has unexpected contents after OTA update'. I'm a noob at this so any advice gratefully received.

Thanks

[Nexus 7 Android Development] gavster26:
Now my n7 says there is no sdcard how can I fix my storage please anyone
[Nexus 7 Android Development] AndDiSa:
[MENTION=4487413]gavster26[/MENTION] can you describe the steps what you have done and in which state you are now?
[Nexus 7 Android Development] gavster26:
[MENTION=2188693]AndDiSa[/MENTION] I fastbooted boot.img system.img then fastboot format cache then booted to system then booted to twrp to flash the latest ota zip
[Nexus 7 Android Development] AndDiSa:
Well there is no need to fastboot flash boot.img / system.img if you later on flashing the OTA. TO be sure that everything is clean, I would do the following steps:

- fastboot erase boot

- fastboot erase system (-w if you would like to erase userdata, too)

- fastboot flash recovery (latest TWRP, if not already installed)

- fastboot reboot recovery

- flash latest OTA

- flash gapps

- reboot
[Nexus 7 Android Development] gavster26:
I tried just flashing just the ota zip but it wouldn't boot past the splash screen for some reason and it wouldn't logcat either. Is there a way to see if my storage is corrupt
[Nexus 7 Android Development] AndDiSa:
[MENTION=4487413]gavster26[/MENTION] Not that I am aware of ...

Are you in a bootloop? In that case the first thing I would try is wiping data. If this does not help either you could try to boot to recovery by pressing the vol- button only and then in recovery have a look at /proc/last_kmsg probably there you can find a hint what's wrong during boot.
[Nexus 7 Android Development] gavster26:
[MENTION=2188693]AndDiSa[/MENTION] the os is running fine it just seems to think there's no storage
[Nexus 7 Android Development] AndDiSa:
[MENTION=4487413]gavster26[/MENTION] that's really strange ... did you already try a fsck on /data (/dev/block/platform/sdhci-tegra.3/by-name/UDA)? Probably it's corrupt and it cannot be mounted during the boot.
[Nexus 7 Android Development] gavster26:
[MENTION=2188693]AndDiSa[/MENTION] no I don't know what that is lol
[Nexus 7 Android Development] AndDiSa:
[MENTION=4487413]gavster26[/MENTION] here the steps in short

- boot into recovery

- connect your pc with the device

- open an adb shell on your device

- umount /data

- umount /sdcard

- e2fsck /dev/block/mmcblk0p9 (if your /data partition is ext4 formatted)

- fsck.f2fs /dev/block/mmcblk0p9 (if your /data partition is f2fs fromatted)

But you probably should be a bit more familiar with these things before using it.
[Nexus 7 Android Development] kc8sbv:
Mine is running great, and TWRP reports its size as 1 gig approximately. What size storage are yours running???

Can you enable Blutooth V4.0 (BLE) on this ROM?

Hi AndDiSa i love this ROM and it has been the only one i have used during 2016 when i changed from stock lollipop. Can i implore you to consider one last task for this ROM before you drop its development completely and that is to enable BLE. Apparently the BT chip has the capability but was not enable as cited

in this link....http://stackoverflow.com/questions/20669590/ble-on-nexus-7-me370t-with-android-4-4-2

"Basically, it seems that the Broadcom Bluetooth chipset within the 2012 Nexus 7 is Bluetooth 4.0 LE/Low Energy (BLE) capable, however, Google never certified it as such, only certifying to the then current v3.0 spec."

This link...https://github.com/manuelnaranjo/android_device_asus_grouper/commit/31756f3c0f364c9c7d07e8813a8b806ec0ddaded....has patches to enable it.

it has also been done by this chap here....http://xdaforums.com/showpost.php?p=44948765&postcount=65.

I would add that this is probably relevant to the Android 7 development that you have started on this forum. I wait expectantly.

What I have to do to flash your rom? I have to put the file into the tablet and then flash it under the recovery, isn't it?
[Nexus 7 Android Development] AndDiSa:
[MENTION=2089857]lollazzo[/MENTION] yes, it's sufficent to flash the ROM, gapps and then SuperSU (if you would like to have su enabled). Nevertheless I would suggest you to try the 7.1.1 version. It's more up to date and more stable than the 6.x one.

Forced "Do not disturb"-Mode

A minor bug I found: reducing the notification sound level to zero forces the "Do not disturb"-mode on, that doesn't happen on my other Android 6 device.
[Nexus 7 Android Development] Geko45:
That's not actually a bug, that's default AOSP behavior. My Nexus 5 (running MM straight from Google) behaves like that. I don't really like it either, but it is what it is. Your other MM device must have overridden it somehow. I do think there is an Xposed module that can change that behavior.
[Nexus 7 Android Development] Moosach:
Yes, I can test this myself, but it costs a lot more time than a quick answer here from some friendly fellow who did it already: Is this 6.0.1 AOSP here faster than 7.1.2 AOSP?

I'm using my grouper only for car navigation with TomTom app (because of the excellent traffic informations). For this usecase I'm looking for the best custom ROM, because the original last 5.somewhat is very slow, espc. when booting ...

Any comments or recommendations?

Thanx in advance.

Update: I'm now running the optimized CM11 version of user animatrix999 and am quite happy with it. Just what I was looking for.

Sound from headphone jack

I've installed the 20160908 build for 6.01 and it seems to be working very well. One problem is that when headphones are plugged into the jack, no sound from the phones nor does it cut off the speaker sound. So, in essence sound only comes from the speaker whether or not headphones plugged in. Has this been reported? Could this be a hardware problem, rather than software?

Thanks for any reply ...Edwin
[Nexus 7 Android Development] skymaule:
OK sorry folks. It really didn't make sense that it was software. Problem turned out to be a faulty ribbon cable going from the usb and headphone jack and now is working as expected. Thanks to dmitrygr and AndDiSa for all your hard work on this project. ...Edwin
[Nexus 7 Android Development] AimiFox:
By the way, you can also root it with Magisk, works perfectly fine.

Also, Benzo-gapps crashed hard for me, so I used opengapps and it worked fine.

OTG + Charging

Does anyone know if this ROM allows USB OTG + Charging? I would like to have my OTG plugged in and also allow for charging. I am thinking of purchasing a split cable to enable this but hear that the kernel must support.

ROM works great, but I noticed that Android System Webview doesn't work. When I use apps that require webview I get a white screen on those apps. Tested with a WebView tester app on the playstore to confirm it.

Anyone have a workaround? I have the latest Android System WebView (version: 83.0.4103.106) but no dice.

Any app with webview should work -- here's the one I use to test: play.google.com/store/apps/details?id=com.app.dr1009.webviewchecker&hl=en_US

tried loading google.com w/ javascript enabled, scrollbar enabled, and with zoom button... white screen.

...so you're saying just top stick with the Google Play Store FCs? I was on this ROM for less than 24 hours because I was scared off by the FCs.

I ended up reverting back to the 6.0 version of this ROM because of it.

I wasn't sure if it would iron itself out, but I'm totally willing to try it again and wait it out.
[Nexus 7 Android Development] AndDiSa:
[MENTION=4925002]meatfest1974[/MENTION] if you are comming from an LP ROM and do not wipe, you need to change the app permissions for Google play servcies to get rid of those FCs. Did you try that?
[Nexus 7 Android Development] Krendelrus:
New things to play with, so nice! [MENTION=2188693]AndDiSa[/MENTION] can I ask you kindly if you could make a tilapia version of this ROM?

Inviato dal mio Galaxy A5 utilizzando XDA One
[Nexus 7 Android Development] AndDiSa:
[MENTION=4908427]UCHIHA[/MENTION] I suppose there are two issues looking at your log files:

- the minor one: google messaging services need access to gps (ACCESS_FINE_LOCATION) which is not granted and due to that it's stopping from time to time

- the major one: com.google.android.webview cannot be found from the package manager. This is an issue already some time around and is related to the automatic updating mechanism from Google. You could try to uninstall (and re-install) the web view updates to see if it improves the behaviour.
[Nexus 7 Android Development] dunjamon:
Flashed back to stock and then installed this ROM, works fine so far...except for the home button. Doesn't seem to do anything in any orientation. Anyone else seeing this?
[Nexus 7 Android Development] UCHIHA:
Thanks dev,

For the minor one,,, yes i do fresh install to provide logcat... And i forgot about grant permission.

But will be great if you can include this patch dev:

https://github.com/opengapps/opengapps/wiki/Notes-for-Android-6.0

To prevent force close first and manual grant permission.

For the major one,

I cannot login to google account (coz i replaced stock webview with the google one) . How google do his mechanism if i not loggedin ?

But nevermind it not too important. Just let stock webview installed for now.

Many many Thanks dev.

[MENTION=3191240]dunjamon[/MENTION] what's your problem with the home button? Works as expected for me.
[Nexus 7 Android Development] offbeatdave:
If anyone is unsure about making the jump to this Rom, DO IT! You won't find a cleaner, smoother MM Rom for the 2012 Nexus 7. It is far superior to the official Lollipop release.

I've no problems with Gapps or the 'Home' button. I have been testing this ROM (alongside another) since it's first incarnations by Dmitry and this one is spot on. I'm running current build (9 Dec 2015), rooted with SuperSU 2.52, with FSTrim running daily. I've also (hopefully) turned off journaling too. I also flashed the Marshmallow bootloader for completeness. Rotation, sound, MTP etc. all work perfectly. It is smooth, clean and certainly a great Rom for everyday use. GApps from the first incarnation of this Rom over at Dmitry's original MM post has worked for me every time I've reset and reflashed. Battery life is also at least as good (probably better than most) as anything I've run on the Nexus. There are no annoying 'extra' apps or settings. To be honest, this could become the 'official' Google release - it's that good and clean!

As an aside I've only just discovered Nova Launcher and it is great with this Rom. Can't believe I've not made the switch earlier. It is now my launcher of choice across all my devices.
[Nexus 7 Android Development] dunjamon:
It highlights when I press it, but it nothing changes on the screen. I have to then use the back button to go back and exit. I also have play services issues. I've gone back to stock 5.1.1 and it all seems to be working fine...but just a bit laggy for now.
[Nexus 7 Android Development] AndDiSa:
[MENTION=3191240]dunjamon[/MENTION] Did you update the permissions for the play services? Coming from 5.x play services do not have all the permissions they need to run without issues on MM, so you need to go to the app settings and enable the permissons they are requesting.
