[MENTION=2188693]AndDiSa[/MENTION] Clean flash the latest build, but some issues with brightness as some of your previous builds and some SOD also. Didn't find anything suspicious.

Google Play service crashing

I had the same problem. For me, the solution was to install Opengapps Pico instead of Mini Dynamic Gapps. ;)
[Nexus 7 Android Development] AndDiSa:
[MENTION=8070926]actp888[/MENTION] pico gapps are always an alternative but do not provide all the apps / services in the dynamic mini package. I am wondering why people do have problems in flashing / running them because I do have still 17MB free in /system after flashing mini dynamic gapps. That should be the same for everyone unless they are flashing other apps which go to the /system partition ... or do have journaling enabled on /system. But this should be automatically switched off with the new ota updater script ...
[Nexus 7 Android Development] topoldo:
Just to say: THANK YOU to AndDiSa.

I used my N7 [2012] 32GB (WiFi only) until yesterday with GtrCraft PureNexus 6.x + ParrotMod.

Yesterday I decided to move to Android 7.x and everything important worked perfectly. Moreover the system is fast!

I have just some minor complaints/problems:

1. In many cases, without any apparent reason, I have a pop-up which reports "MTP app has stopped to work" (at least this is the the Italian translation into English of the message which appears).

Please note that MTP worked badly at least under Android 6.x, while it was ok until 5.x (so it seems not a problem of usb cables).

2. The lack of Pure App causes the impossibility to tap twice the screen to switch it off/on it as I used tio do. Moreover I was not able to find yet any other free app which reports the percentage of battery charge on the side of the battery image on the status line as Pure Nexus app do.

For those who were unsuccessful: before upgrading from GtrCraft Pure Nexus 6.x + ParrotMod to AndDiSa 7.x I performed all the operations described in the OP of this thread (and also in the second post) and I used the Mini_Dynamic_GApps-7.x.x-20170121.zip as suggested there.

This way I had only minor permission problems at the beginning of the configuration with no need to do anything: I just went on with the procedure and I was also able to root the device with the "systemless method" suggested there.

Cheers,
[Nexus 7 Android Development] actp888:
I did not enable journaling (I don't even know how to do that) and I had not flashed any apps other than the Nexus 7 camera app (the 2.x version, which seems to be the only one that works with your ROM). Play Services crashed as soon as I opened Play Store.

By the way, this was the first Custom ROM I ever flashed. I used Wugfresh's Nexus Root Toolkit and it was really quite easy although I'm an absolute beginner.
[Nexus 7 Android Development] Bakica:
I suggest you to install camera JB+ apk, no need to install it as a system app (https://play.google.com/store/apps/...apk&pcampaignid=APPU_1_feChWInOEaXM6ASLwbTYBQ)
[Nexus 7 Android Development] AndDiSa:
1) Regarding the MTP issues it's a known 'bug' but it doesn't really invoke any issues as the service is restarted directly and you are able to transfer data between your PC and the tablet.

2) DT2W is (currently) not implemented on my kernel (@daniel_hk has the DC-kernel where it should be enabled), probabyl I'll integrate the feature, too, but I am not sure yet

3) the percentage can be displayed by enabling the SystemUI Tuner (Here you can find a brief description on how to enable it)and then modify the percentage settings.

Tanti saluti!
[Nexus 7 Android Development] topoldo:
I see...

I use Nova Launcher (paid version) and I noticed I could implement the double tap to make the tablet to sleep. Now I lack only the double tap to wake it!

I found an app on GooglePlay which does the same thing, but both SistemUI Tuner and this app I found do is simply to make the percentage apper inside the battery icon. The font is very small and thin, so it does not appear so evident.

I prefer the PureNexus implementation, ie a percentage on the right side of the icon of the battery, which is also what I have on my Asus ZF2.

Anche a te! :)

Hi

How I can use thetring hotspot in tilapia?
[Nexus 7 Android Development] lotte67890:
Which is what I also would like to know ...
[Nexus 7 Android Development] AndDiSa:
[MENTION=7913386]k ahangar[/MENTION] [MENTION=4943417]lotte67890[/MENTION] unfortunately I do not have a tilapia device ... probably one of the others can lend you a hand.
[Nexus 7 Android Development] mausbock:
Tilapia never had officially support for tethering as I remember.
[Nexus 7 Android Development] shantur:
Is the slow charging issue solved now?
[Nexus 7 Android Development] AndDiSa:
[MENTION=3275672]shantur[/MENTION] I did some tests and I got between 350 and 1050mA, while the average is between 500 and 750. Unfortunately I do not have the original charger and cable otherwise I would expect charging rates up to at least 1500mA, but I didn't see them yet. As Enropy512 found out slow charging rates are mostly related to a very sensible AICL of the smb347 chip. Probably people having still the original equipment (D+/D- shortened cable and 2.1A charger) can report about their charging rates.
[Nexus 7 Android Development] shantur:
I use my N7 as a car tablet with Fast Charging with OTG support and Android 7.1.x builds just make it unusable. It hardly charges well anymore. It discharges even when a charger is connected. It used to be so much better in Android 6.0 not sure what has changed.
[Nexus 7 Android Development] AndDiSa:
[MENTION=3275672]shantur[/MENTION] I've merged the OTG charging feature in the last build, but I was not able to test because of a lacking environment ... probably there is also one commit missing which I added a few days ago on my test build. Your feedback would be very fruitful .. :)

btw: in the kernel messages the current charging and limits are reported frequently
[Nexus 7 Android Development] Obscurax:
Hi,

First of all thank you for this great ROM. It really made this old turd usable again.

Today I upgraded and experienced some issues with Gapps. Contrary to what you advice I use OpenGapps Pico and SuperSU 2.97 stable (not systemless).

I always first wipe /system /cache and dalvik-cache and then install the ROM, Gapps and SU. But this caused problems with Gapps, the store wouldn't load, etc.

So to get it working I wiped again as above, installed the ROM, rebooted to recovery and Installed Gapps + SU and then reboot system. Everything was working again.

I'm also experiencing problems with the lock screen. I'm using a pincode to unlock the tablet. I always have to swipe 3-4 times to unlock the screen to be able to enter the pincode.

Is this a known issue?
[Nexus 7 Android Development] AndDiSa:
[MENTION=4877238]Obscurax[/MENTION] If you use pico gapps you can flash SuperSU in system mode, too, because there remains enough space in /system only in the case you are flashing the dynamic mini gapps package systemless SuperSU is a must.

Regading the unlocking issue, it's a known bug and it looks to me that it is related to power saving / sleeping modes. I noticed that it is difficult to unlock when the device was not used for a certain time period while unlocking it after only a few minutes in general is no problem.
[Nexus 7 Android Development] AndDiSa:
[MENTION=3445844]vetzki[/MENTION] that looks very good, thank you very much. I am using a 2.0A charger and cable from HTC and there the charging current is much lower.
[Nexus 7 Android Development] shantur:
In my setup all the cables and chargers are same as Android 6.0 and I still see the difference. D+ and D- are not shorted as it is working with OTG.
[Nexus 7 Android Development] Promez:
I'm still having a lot of crashes and FC's, you too guys?

Inviato dal mio Nexus 7 utilizzando Tapatalk
[Nexus 7 Android Development] mausbock:
I only have FCs in News Republic App. All others run very well and without crashes.
[Nexus 7 Android Development] AndDiSa:
[MENTION=4285036]Promez[/MENTION] crashes and FCs in general are an indication some permissions are not set correctly. You can manually correct that in the app settings. Another possibility is a forgotten wipe when coming from a different ROM or flashing SuperSU in system mode when there is not enough space left on /system partition.
[Nexus 7 Android Development] k ahangar:
With use thetring you can share internet of your sim card to other devices...

I hope find a way to use in tilapia...
[Nexus 7 Android Development] dookie23:
I recently updated to the latest 20170207. Everything seems to be working but my Chrome was not able to update. When I tried to update Chrome, the Playstore would keep crashing. I thought I screwed up the firmware update so I decided to start from scratch.

After installing the new firmware and gapps (tried 20170214 pico and 20170207 pico), I am still not able to install Chrome. Play Store will just keep crashing when I attempt the installation.

Any suggestions? Thanks.
[Nexus 7 Android Development] Ahkah:
I noticed a crash of the settings program when trying to define a PIN for screen lock. I repeated the procedure, and the second attempt was successful.

I am missing some features of Cyanogen, though, which I got used to, so this "ROM" looks somewhat spartan to me, but otherwise it seems to work great, and finally stability, security and speed are more important than luxury.
[Nexus 7 Android Development] Eliastik:
What do I need to do to update my Nexus 7 2012 (8 GB) from your ROM Android 6.0.1 AOSP to this Android 7 AOSP ROM? I wiped /system, then I flashed the ota-package and the Mini_Dynamic_GApps-7.x.x-20170121.zip then I wiped /cache and dalvik cache but Google Play Service crashed every time. I also tried the Opengapps Pico but this not work. I have restored a Nandroid backup of Android 6.0.1 after that (I had an error 225 from TWRP, I had to fastboot format every partition before restores the backup).
[Nexus 7 Android Development] AndDiSa:
[MENTION=8074969]Eliastik[/MENTION] if you want to update von 6.x to 7.x it's probably better to to a factory reset before installing the ota package.
[Nexus 7 Android Development] AndDiSa:
[MENTION=2723508]dookie23[/MENTION] Really speaking, I don't have any idea ... but you are not alone, if you search the internet this error is happening for different users on different builds and devices. Probably a permission issue, just a guess. Did you check the permissions in app settings? Did you try to enable write permission to sdcard in developer options?
[Nexus 7 Android Development] dookie23:
I can't find the write permission to sdcard in developer options. The closest option is "Force allow apps on external". Is that what you were talking about?

All the permissions were granted to Play Store and Play Services but I am still having this issue.
[Nexus 7 Android Development] AndDiSa:
[MENTION=3275672]shantur[/MENTION] probably there is a fix misssing in the kernel included in the ota for fully supporting the otg-charging. If you would like to test a kernel with a fix, you could fastboot flash the kernel in the attachment.
[Nexus 7 Android Development] tpuserhp:
[MENTION=2723508]dookie23[/MENTION]. Not sure what do you mean starting from scratch. But I 'd wipe caches, system and data partition first. I would then flash the rom, reboot into recovery and then flash gapps.

Wipe caches and reboot and see if this helps.
[Nexus 7 Android Development] dookie23:
[MENTION=5333182]tpuserhp[/MENTION] Yeah, I did exactly the steps you provided but I still got the same issue. I tried both Opengapps Pico as well as the Dynamic Gapps from the OP.
[Nexus 7 Android Development] AndDiSa:
[MENTION=1944312]dokie23[/MENTION] did you restore something e.g. using Titanium? How did you get Chrome installed (it must be already installed if you want to update it)?
[Nexus 7 Android Development] dookie23:
I am not using Titanium at all.

Previously, I had Chrome installed (downloaded from the Play Store) and that was when I was running the 20161213 build. It was fine until I installed the latest 20170207 build and Chrome wasn't able to update. I decided to remove Chrome and install it again but that also failed. As I mentioned before, I thought I had screwed up the ROM installation so I did a Factory Reset, installed the latest ROM and installed GApps. But, with a newly installed system, Chrome is still having trouble installing (as well as Opera).

Thanks for your help.
[Nexus 7 Android Development] tpuserhp:
It seems you are doing the steps right.

I use open gapps with the following file name format

open_gapps-arm-7.1-pico-20170205.zip

Please double check yours to ensure you did not pick wrong one like 7.0.
[Nexus 7 Android Development] dookie23:
Thanks for the reply.

I have the right files:

open_gapps-arm-7.1-pico-20170207.zip

open_gapps-arm-7.1-pico-20170214.zip

The Playstore is working and I am able to download and install some of the apps (e.g. I just installed the XDA app). But something like Chrome and Opera, I am not able to install at all and they will crash the Play Store process.

What I am doing right now is to sideload the Chrome apk and it seems to be a temporary workaround.
[Nexus 7 Android Development] tpuserhp:
It is hard to tell what went wrong.

If I were you, I would redownload the files and check the md5 hashes to ensure no corruption. I would wipe and flash as I mentioned before for a clean install. Install chrome and test before other apps.
[Nexus 7 Android Development] dookie23:
Thanks for the help.

I just had all my other apps reinstalled successfully. It seems that Chrome and Opera are the only apps that are not installable through the Play Store. How strange is that? I am surprised that no one else is also having the same issue.
[Nexus 7 Android Development] k ahangar:
hi [MENTION=2188693]AndDiSa[/MENTION] and thank you for your efforts

your rom is so fast and i like it :o

in tilapia carbon rom by daniel_hk thetring hotspot is available.

please Benefit of that for Creation this item on tilapia:fingers-crossed:
[Nexus 7 Android Development] Charles IV:
On the instructions, you mention flashing the ota zip. Is there any benefit of doing this instead of the normal zip? (Considering you're still flashing it), or is there something you've included in your ROM which benefits from this?
[Nexus 7 Android Development] AndDiSa:
[MENTION=7211583]Charles IV[/MENTION] the zip files provided as dowwload are ota-zip files, e.g. you apply them via recovery to the current rom. The only difference is, that they contain a full system instaed of a differencial update. So I do not understand fully your question. What do you mean with 'normal' zip?
[Nexus 7 Android Development] shibadoo:
Updated my tilapia to the most recent version, everything worked perfect again. Rooted the device (systemless). On the device itself I have root rights, also when I open a terminal emulator and type in "su". If the device is booted up and I open an adb shell, there is also no problem to elevate my rights with typing "su" in the shell. BUT: When booting into recovery (TWRP 3.0.2), I am not able to get root rights. If I open a terminal in TWRP and type in "su", it says "sh: su: not found". If I look for "su", it is installed in "supersu/su". Changing into /supersu and typing "su" again does not work, same message as above. If a open an adb shell and type in "su", it says "/sbin/sh: su: not found". Searching for su delivers the same location as above (/supersu/su), changing into /supersu and typing in "su" delivers again "/sbin/sh: su: not found". With the january release I did not have these problems. Any advice on this???
[Nexus 7 Android Development] AndDiSa:
[MENTION=980259]shibadoo[/MENTION] If you boot into TWRP and open a shell (either directly or via adb) you are always root, there is no other user than root.
[Nexus 7 Android Development] reynard80:
AndDiSa, I tried this ROM with the fixed kernel for USB host support (as per your post in the LineageOS thread).

I managed to get an USB DAC plus charging working, which is great! It seems to work pretty well after a short test. Will you also be applying the settings menu for USB host mode, as in Timur's USB ROM?

I keep getting an MTP Host error though, which is a bit annoying. I saw that this is a known issue, but will it be fixed?

Furthermore, am I right that ParrotMod settings are already applied in the ROM?
[Nexus 7 Android Development] AndDiSa:
[MENTION=3102926]reynard80[/MENTION] Thank you for testing and provinding me with some positive results. Regarding the settings, probably I'll be integrating some (kernel-) settings into the ROM, especially while I am playing around with zram again (which is already enabled in the boot.img you've tested ... :))

Regarding MTP I am not sure where to look because for me it happens at most once after I booted a new ROM after that it never happens again ... If I find the time, I'll have a deeper look at it.

Parrotmod is not needed because I applied similar settings as defined in the mod.
[Nexus 7 Android Development] shibadoo:
Didn't know that, but makes sense somehow. Thanks!
[Nexus 7 Android Development] Charles IV:
When I build, there is a zip with the date, unofficial and the os included. Like the ones aaopt uploads to his lineage os thread. These are also flashed in recovery. When i look inside them, they contain exactly (i think) the same stuff, just they're called by different names.
[Nexus 7 Android Development] AndDiSa:
Names are sound and smoke ...
[Nexus 7 Android Development] Ahkah:
Camera sort of working?

Maybe it has been discussed before, but I just tried this camera app (Nexus 7 camera).

The pictures created are more like modern art than photos. While the preview is fine, I get two files per shot, one looking like modern art and the other one like more modern art (more modern or more art, English is more ambiguous than other languages). The pictures are composed of quite large squares filled with plain colour, and while one of these looks a bit like reality, the other one is nearly abstract.

Rather funny....
[Nexus 7 Android Development] AndDiSa:
[MENTION=7913386]k ahangar[/MENTION] I'll have a look at the patches and will probably include them into the next build.
[Nexus 7 Android Development] AndDiSa:
[MENTION=5917730]Ahkah[/MENTION] I am not sure but it looks to me as if the camera is using an outdated API. I am using Better camera from the play store and I do not have any issues, even if the resulution of 1,2 mega pixel is not very impressive.
[Nexus 7 Android Development] :
gapps not showing

I flashed the rom and dynamic gapps package on nexus 7 grouper, both flashed successfully, but the gapps are not installed, open gapps pico is also not working. How can i install gapps?
[Nexus 7 Android Development] k ahangar:
dynamic gapps is more than 200mb!

isn't this very big for our devices (with 1G ram)?

I don't install it yet, jus think maybe device will slow, no?
[Nexus 7 Android Development] adstraylight:
What I do:

1. If coming from another Rom, go into Advanced Wipe and wipe everything except Internal Storage. If Upgrading from a previous version of the same Rom, then just wipe /system.

2. Flash the new Rom only. Do Not reboot to system!

3. Go into Mount, and uncheck /system, if it is already unchecked then check it and then uncheck it. This will explicitly tell TWRP to unmount the System partition.

4. Flash Gapps, my preference if Open Gapps pico, but be careful here as the package should be about 133MB & sometimes the nightlies fail to build properly so end up much smaller than this.

5. Wipe caches just to be sure, and reboot system.

6. Once the device is set up and settled, Flash SuperSU.

Hope this helps..

---------- Post added at 10:56 AM ---------- Previous post was at 10:49 AM ----------

Dynamic Gapps packages, tend to have an installation script that adapts to your device, IE take account of screen dpi etc., and so don't install the whole package. The RAM is irrelevant as the system looks after that while running. What really matters is the space in the /system partition, and if the OP has recommended a certain package, then this has been tested on their own device.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7913386]k ahangar[/MENTION] The size of the package has nothing to do with the memory allocated by the apps. Apps do not occupy memory unless they are really started ...

Regarding occupation of storage space and dynamic gapps: in my experience they fit into /system but there is really very few space left after installation (<= 12MB), so if you try to install other apps / libs / sounds / images / ... on /system installation will fail.
[Nexus 7 Android Development] Ahkah:
Well, works, kind of. It has advertisements, and initially was not even able to save a single photo. I had to manually change the storage location from "Handy" (what the **** is that?) to "User Defined Directory", got some MTP service crashes and finally managed to set it to "DCIM/Camera".
[Nexus 7 Android Development] adstraylight:
[MENTION=2188693]AndDiSa[/MENTION] further to our discussion about the WiFi, I think you're probably right about the instability not being kernel related, and so was wondering if it was possible to have the option of using the Legacy DHCP client that was available in the dev options of the MM ROMs?

This option was removed in N, but I suppose Google didn't have our device's hardware in mind when they took this decision ?

I ask as I recall having WiFi issues with the default client in MM, and it being much improved with the legacy alternative.

I find the problems occur when there is another device actively using the same router in close proximity to my N7, or when my extension AP is also within range of my primary (and vice versa).
[Nexus 7 Android Development] aaopt:
Fascinating. I would not imagine that DHCP itself would be affected by proximity; there must be more to the story. But your proximity observations are consistent with mine... my wifi does seem to be slower when the tablet is near my laptop. On lineageos I am not getting wifi connection drops per se, but speeds go way down from time to time, to the point where Google Play gives up on updating apps.

I bought an ASUS router hoping it might happen to work better with this tablet. The other devices like it better than my old router but the tablet still has issues.
[Nexus 7 Android Development] adstraylight:
Do you think it may have something to do with the fact that the grouper isn't capable of using the 5ghz band? I ask because restricting the device to 2.4 has been discussed as a possible fix for similar issues on the N5 after upgrading to N, only for users to find this option has been removed from the advanced WiFi options in N.

Perhaps competition for bandwidth/interference causes N to attempt to switch band, hence the dropouts?
[Nexus 7 Android Development] Promez:
Granted every permission and upgraded from November build to latest with full wipe.

On system i've 144mb free

Anyway it's not a big problem, the rom runs smooth!
[Nexus 7 Android Development] :
[MENTION=2583740]adstraylight[/MENTION] yes this worked, thank you...
