Just to say thank you

Have tested several Nexus 7 roms ; this one & the way it is supported so actively by AndDiSa make it a wonderful experience. Combined with ParrotMod , this is the rom to choose for stability & speed. Thanks again.
[Nexus 7 Android Development] williamlaw:
Just tried to flash this rom and Gapps for several times but Gapps haven't installed ....

Please advice.

Thanks
[Nexus 7 Android Development] AndDiSa:
Which gapps? You need to flash the mini / micro / nano version, otherwise there is not enough space in /system. Please follow the instructions in the OP and everything should work fine.
[Nexus 7 Android Development] 11sword11:
I have the same thing. After disconnecting the OTG cable, the tablet freezes and then reboots on this firmware :(

Had to go back to 4.4.4 firmware, there is no such problem.
[Nexus 7 Android Development] AndDiSa:
Did you unmount the OTG before removing the cable? Could you please send me a log of the crash? (/proc/last_kmsg)
[Nexus 7 Android Development] 11sword11:
Yes.

Here is the last_kmsg, hope it will help to fix.

Thank you for your work throughout the rest of the firmware works fine :good:

I flashed OpenGapps (Pico).

Fianlly, I tried recommend Bento Gapps then ok

I made the mistake of flashing the wrong parrotmod, flashed the universal one and it works, while I wouldn't call it buttery smooth its a lot more acceptable with journaling off auto trim and parrotmod
[Nexus 7 Android Development] Phandroid:
I'm getting the "unfortunately google play services has stopped" error and no matter what Gapps version I flash or what aledged fixes that can be found on the internet I try, the error persists.

Any suggestions what I'm doing wrong? Obviously I did not flash each and every Gapps package around, I did try OpenGapps and also BenzoGapps that are suggested at the beginning of this thread, though.

Any help is welcome, since the tablet is fully wiped anyways, I could give anything a try...

Thanks in advance!
[Nexus 7 Android Development] AndDiSa:
[MENTION=892402]11sword11[/MENTION] I think I've found the reason for the issue. The next version of the ROM should work with OTG-devices without problems.
[Nexus 7 Android Development] AndDiSa:
[MENTION=2879529]Phandroid[/MENTION] generally it should be fine to flash the ROM, then Benzo-Gapps, then SuperSU (if you want to root). Please wipe cache/dalvik before restarting.

Probably it's important to know, that I am using systemless - root, which lets some additonal memory on /system. I am using SuperSU 2.62 which installs systemless while other versions of SuperSU normally install on /system. This may lead to problems due to too few memory on /system when flashing gapps.

Great news! Thank you! This is an important bugfix for anyone who uses OTG

Wi-Fi issue

Hi! My WiFi disconnects after while tablet is sleeping. When I push on/off button, I can see WiFi icon in notification bar, but it's empty. So, WiFi connectivity is "On" all the time, but I can't get new emails, social media notifications etc until I "wake up" my tablet. Is there any way to disable this feature :)
[Nexus 7 Android Development] AndDiSa:
It's a feature of MM, it's called 'doze' mode. Be assured that you receive e-mails / notifications even if the icon is 'empty'. The tablet from time to time awakes, reconnects to the network and looks for outstanding messages.
[Nexus 7 Android Development] ataud:
I might be wrong, but "doze mode" can be disabled for specific apps, which should mean that they will receive notifications just-in-time, but it seems impossible, because tablet won't keep WiFi connection alive for just one app, even if I'll turn off "doze" for Gmail (in example).

So, is there any way to disable "doze" system-wide? Or this "feature" is mandatory? :D

Thank you for this great rom, by the way! It is so nice of you, to bring N7's back to live! :)
[Nexus 7 Android Development] AndDiSa:
It depends a bit on what you want to receive. Why do you want to keep the connection 'physically' open? Logically it remains open and apps will receive notifications even in doze mode. Probably they arrive not immediately, but with a little delay. If you exclude an app from doze, those apps will remain active and will hold the WiFi connection open as long as needed and probably will interrupt doze mode more frequently.
[Nexus 7 Android Development] ataud:
Example: Someone send a message in VK app, which is excluded from the "doze". I will not be able to respond immediately, because VK will not get notification just-in-time. Same thing with Gmail notifications (like, parcel tracking activities, bank account notifications etc). I tried to leave tablet for a few hours and see if it will get notifications while I'm not touching it,and it seems like it's don't. But after I unlock the screen - WiFi connectivity appears again, and all of notifications appear at the same time. I think it's easier to handle 2-5 emails at once, than 20. :)

It is not critical, but it would be nice to be able to choose "dose" on and off system-widely.

http://www.androidcentral.com/inside-marshmallow-what-doze-how-do-i-use-it-and-what-does-it-do
[Nexus 7 Android Development] ataud:
Thank you, it is a good explanation! Now I know that doze can't be disabled even if it is useless for me :(
[Nexus 7 Android Development] sco0ter:
You always could try and put the apps notification permission up to "treat as priority" in the apps settings to see if that helps
[Nexus 7 Android Development] ataud:
Thank you, I'll try! And I definitely need to read more about new Android features :D

Very pleased with the performance of this ROM but for a freezing issue I get every 3 or 4 hours that requires a reboot. I've had it since the first release. Anything. I can do to fix the issue?
[Nexus 7 Android Development] ed028:
the same happens to me
[Nexus 7 Android Development] AndDiSa:
Please describe your configuration in more detail

- which version of the ROM are you using?

- zram enabled / disabled?

- which application(s) are you using?

- f2fs or ext4 filesystem, disabled journalling on ext4?

- ...

Probably you can also provide with a logcat?
[Nexus 7 Android Development] perky55:
I'm new to all this I'm afraid so might struggle to answer your questions.. I'll Google how to provide a logcat but in the meantime I'm using Build 20160309 and benzo gapps installed following the steps in your initial post. I didn't enable zram I don't think and it seems to freeze with Firefox and chrome after an hour or 2. Sometimes less. I'm using ext4 and I ran the script to disable journalling but I'm not sure if it took. I ran it from within twrp.

Thanks
[Nexus 7 Android Development] AndDiSa:
Chrome and Firefox are both known to use a high amount of memory, especially when using several tabs in parallel. Some hints to improve performance: Try to use the built in browser instead, run fstrim regularly and try to keep free at least 4GB.
[Nexus 7 Android Development] SX86:
Runs like a charm on my Nexus 7! I found the right combination of settings to keep it running smooth without the need for frequent restarts.

First of all, I'm running the latest version of the OS and of the kernel. No root. Pico gapps from opengapps.org.

Next, and this is where it gets interestingly powerful, I set the option for "background process limit" to "4 processes at most" in developer options. Ever since I changed that, I always have at least 200 Mb of RAM free, which is required for smooth operation and fast task switching.

What that option changes is the amount of cached background processes that android keeps in memory. If you look at the list on your device, you'll often see apps in there that you rarely use. This option takes care of clearing the RAM for you, leaving active app and services running at their best.

The only issue, it needs to be set again after a reboot...but that's a very minor issue!

Enjoy!

[Nexus 7 Android Development] Codster314:
Manually set the permissions for the OpenGapps? Does this ROM include the patch listed below?

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

AOSP doesn't include it by default, but I think most ROMs have it included. It just automatically sets the permission of the Gapps so that they don't force close during the first boot. If this patch isn't included in this ROM this is probably why OpenGapps Nano (and any non-modified Gapps Package) won't work.
[Nexus 7 Android Development] AndDiSa:
Yes, it does include the patch. Most likely people do not flash again the gapps after updating the ROM to a new version. This may lead to force closes, especially for the play services. In general flashing the ROM-zip, flashing the gapps and optionally flashing SuperSu should be fine.

It looks like every time I did a wipe I used the advanced wipe every time. I tried it again and didn't do advanced wipe and it worked first time.

Now running very good. My nexus has never ran so good.
[Nexus 7 Android Development] Codster314:
I found this out as well. I've always did:

Wipe > Factory Reset

Wipe > Advanced > Wipe data/system/cache/dalvik

Install > ROM

Install > Gapps

If I did the above procedure, the Benzo Gapps works fine, but the OpenGapps do not install right. So I've always thought OpenGapps never worked on this ROM.

I've just tried with a FactoryWipe (no System Wipe under advanced after).

Wipe > Factory Reset

Install > ROM

Install > OpenGapps

And it works now... Note, I still wiped System to make sure no gapps were there prior (Wipe System, Install ROM, Restart into ROM, Then FactoryWipe, Install ROM, Install OpenGapps).

Weird little bug, and weird Benzo Gapps works fine after wiping system, then installing rom, but not OpenGapps with the same procedure.

Happy I got my OpenGapps working though. Thanks! I've tested with OpenGapps Nano/Pico, both work).

EDIT: I am using TWRP 3.0.0-0. And the latest OpenGapps/ROM.
[Nexus 7 Android Development] AndDiSa:
I can agree that there are some issues with wiping in TWRP(I am currently on 3.0.1.0) ... I tried to wipe today, but it succeeded only partially :(

All of my installed apps were still available even with most of the settings ... really weired.
[Nexus 7 Android Development] perky55:
I've updated to the latest version and I'm still seeing freezing issues . I think it is related to having a few tabs open. I've set "background process limit" to 4 which might have helped a little but I'm still seeing the issue. I've attached a logcat I took a few days ago. Thanks.

good day. what GPU clock is set by gefault in kernel? because recently simply 2d games freezing very often on start.
[Nexus 7 Android Development] AndDiSa:
2d graphics are tendered by the CPU, not GPU, unless you force the system to use GPU also for 2d graphics. Nevertheless I suppose it's more related to memory management because generally apps are kept in memory until the memory is needed by other processes. If you start an app which requires much memory it may take some time until the memory is freed and this is some times blocking the start of apps.

Any ideas on how to get now on tap working? Thanks for the ROM.

Edit: After changing the assist and voice input default application to none and back to Google app appears to have fixed it.
[Nexus 7 Android Development] :
Hello, thank you for this rom. I appreciate how its just stock Android. I tried using convert to f2fs and it didn't boot up. I did what you suggested on disabling journaling which did make a noticeable performance difference but I'd very much like to use f2fs. I see it in the list of supported features added. What were the steps you used to do that?
[Nexus 7 Android Development] pclov3r:
Use TWRP to change data and cache to F2FS. Leave system as ext4.

It appears that with the ROM it's not backing up any data. It also has issues when attempting to restore data,

When go to backup & reset it says backup to debug-only private cache.

This all appears to be caused by the build target it's set for.

https://www.reddit.com/r/Android/co...pps_use_the_new_data_backup_system_in/cx9aeb7

Android build target list: https://source.android.com/source/building.html#choose-a-target

If you switch the build target from userdebug to user it will probably fix the issue. Should be simple to fix

If i'm not mistaking you just need to change https://github.com/AndDiSa/android_device_asus_grouper/blob/aosp-6.0/vendorsetup.sh from add_lunch_combo aosp_grouper-userdebug to add_lunch_combo aosp_grouper-user

Finally re-run . build/envsetup.sh and re-build it.
[Nexus 7 Android Development] AndDiSa:
Thanks for the hint, I'll try to build the next release with the user build mode.

A user build didn't fix the problem sadly tho it should have. Despite that it appears you should use a user build type anyways.

No idea why it's not doing it by default.

[Nexus 7 Android Development] AndDiSa:
I've found a solution for that issue (even if it took a while) and it has nothing to do with the build mode. For whatever reason the settings for the backup transport service are not being set correctly by using the settings screen, but if you switch the bmgr transport mode by adb / command line you can get it configured correctly. There are several Custom ROMs having that issue. If I find some time I'll add a more detailed description to the OP.

I love this build! My nexus 7 2012 has had lag issues with every build I threw at it. Now I feel it is usable again.

The only issue I am getting is that I drained the battery down to about 10% last night and it took almost 20hrs to get a full charge. Any ideas on what to fix? I know the cable and adapter are good since I charge both my Moto X phones with it and they get a full charge within an hour or so.
[Nexus 7 Android Development] massima:
I use this technique:

1) charge it;

2) plug/unplug the usb port from the power adapter (electric socket side) for 7 times.

Now my nexus charge in 3,5 hours:good:. I can suggest to install a battery monitor app to check the eletricity value (from +50mA max to +500mA and over).
[Nexus 7 Android Development] ludespeedny:
Ok, I'll try that.
[Nexus 7 Android Development] ludespeedny:
No luck so far. Still taking over 2 hrs to charge from 80%
[Nexus 7 Android Development] AndDiSa:
I suppose there are several factors. Normally the battery should full charge in about 4 hours having a charging rate of 2A. To get this high charging rate you need to have

- a charger providing this high power

- a special cable signalling the device that it may take more than the max. specified USB power of 500mA

- a kernel being able to interpret the signal and setting this high charging power request.

Even if everything of the above listed features are provided there might be an issue with the battery itself. Our devices (and batteries!) do have about 4 years of life now. Unfortunately Lithium batteries are aging and this might lead to a lower charging rate, too.
[Nexus 7 Android Development] massima:
I use the app "Battery Monitor Widget" to monitor the electricity flow (you need a high value to reduce the charging time).

You could try to clean contacs of the usb port with alcohol (useless for me) or buy a new charging port (it will work).

I installed the new rom yesterday and tried it out last night.

Seems to me to be really slow to respond. Facebook timed out numerous times. Inbox and OWA were slow to respond.

Just wow! a butter smooth rom & probably the best one for my Nexus 7 2012!!

1. Installed latest TWRP

2. Wiped Everything(Including my Data-- No essential files was stored so doesn't matter).

3. Flashed the latest OTA zip file & Then Flashed the Gapps mentioned on this thread.

4. Lastly Flashed the SuperUser zip file and rebooted.

5. After successful reboot, I finally rebooted into recovery once again and Flashed xposed. Everything works fine.

Just ONE ISSUE i'm facing: My audio kinda comes and goes time to time. I hear my notification sounds, I can play youtube video on speaker but When I play a movie with mxplayer the sound is GONE! The video is running but there is no Sound. Sometime Youtube videos does that too! Video is buffering but No sound on that video. If that happens with youtube, I play my notification ringtone to start the speaker & then resume that youtube video . STRANGELY the sound comes :0
