[Galaxy Tab 10.1 Android Development] decatf:
It is up to the app developer to support CPU architectures. The PlayStore doesn't do anything in that department. The PlayStore will provide whatever the developer publishes.

The Tegra 2 is the only commercial Android device with a CPU architecture that does not have NEON. The app developer maintains the code path for whatever architectures they choose. The most common is ARMv7a with NEON. Less popular are non-NEON, x86, or MIPS. There are not many apps that support x86 or MIPS either.

Android apps are written in Java but they can be implemented with parts of native code (C/C++). Java bytecode is compiled locally into native instructions. The parts of the app implemented in native code are provided as binaries. So it's the decision of the app developer to compile and publish native binaries for which ever architectures they choose.
[Galaxy Tab 10.1 Android Development] UncleDick:
So far, Maps & Earth continue to work for me. I don't use Drive, Sheets, & Docs, but have not heard any comments about them requiring NEON.

So I dirty flash 0809 over 0806 and still got the same problems (long boot time, no sdcard access, system ui crashing, etc) so I did a clean install of 0809 and the tab was in a boot-loop for 4 hours before I turn it off. I've been using this rom from it was first release and this is the first time its giving me problems. Anybody have any ideas I could try?
[Galaxy Tab 10.1 Android Development] prisoner881:
Thank you again for bringing such long life to this aging platform. My six-year-old daughter uses this daily for all sorts of stuff so I'm glad it's been saved from the trash bin.

One thing I've noticed that won't run: Minecraft PE. I suspect this is due to the aging closed-source, binary-old video drivers. Is this the case? If so, is there anything that can be done? Any tweak or alteration I can make that would allow Minecraft PE to run? There was a time a few builds ago when YouTube wouldn't work because of the video blob drivers and now YouTube works. I hope there's a way to get other apps like Minecraft working using the same diligence. Let me know if there's anything I can do to assist (i.e. crash logs, etc.).

Thanks!

is anyone else unable to set their wallpaper with a custom image? It says it cant load the photo with images taken from the camera or copied onto the tablet, but it works if you use a copied image from the file manager. The permissions for both photos appear to be the same.

I tried to install aosp-6.0-p4wifi-20160806.zip with Opengapps pico, Trim-Kernel and SuperSU today in my P7510. I exactly followed the installation-instructions

However after booting I get the message:

During the install I saw the following messages:

I was able to install SysLog but it always tries to write to the external storage: "The external storage is not writeable, unable to save logs." I used Stickmount to enable the USB-Card, but it did not help. I can not see 'devices' in my FileManagerHD. So I assume the mounting of the sdcard goes wrong somehow. If someone explains me how, I'll gladly save Logcat, Kernel, Main Log or whatever is needed.

But I was able to see in the Live Logcat, that I get the same messages as mistersixt did:

decatfs answer to mistersixt was:

It should be fixed on the 20160809 build for p4 and p4tmo. There was no problem the 20160806 p4wifi build.

Well, I use exactly aosp-6.0-p4wifi-20160806.zip

aosp-5.1.1-p4wifi-20160305.zip installed without any problems on the same tablet.

Thanks

Is this Rom compatible with 7501 Tablet?

Gesendet von meinem LG-H815 mit Tapatalk
[Galaxy Tab 10.1 Android Development] decatf:
ROMs newer than 20160428 have TRIM by default. Don't install the 20160414-TRIM kernel. It is not compatible with recent ROM builds.
[Galaxy Tab 10.1 Android Development] jerryhou85:
Yes, I remember seeing someone in this thread posting his experience.
[Galaxy Tab 10.1 Android Development] TerraD:
Thank you. I flashed the 20160806 again without Trim and the above problem has gone!

Is it normal to have many "Unfortunately, MyApp has stopped" messages? Right after starting Android I have "Unfortunately, android has stopped." Later about 50% of my apps terminate prematurely with this message. Even FAQ of SysLog crashes with this... I searched through this thread and did not find other users mentioning this.

I still have the mount error during install:

Is WebView installed in the PlayStore? If so uninstall it. That is also compiled for NEON now.
[Galaxy Tab 10.1 Android Development] TerraD:
Yes, I found an explanation, that some versions of WebView cause this type of error. So I installed the version recommend. However: I had the "Unfortunately, MyApp has stopped" before installing WebView..

I uninstalled WebView. The behaviour is slightly improved: SysLog FAQ no longer produces the problem. :) However, most Apps still do...

Looks like app crashes. Not the ROM. Except maybe one where the camera was used. The camera is mostly broken so that's expected to be buggy.
[Galaxy Tab 10.1 Android Development] TerraD:
Is it common that Apps running flawless under 5.1.1 (and earlier) will crash under 6.0.1?

I installed till now about 15 Apps, 3 of them causing this type of crash. Seems a bit much to me. Today even PlayStore showed this behaviour (once).

The app using the camera was 'Barcode Scanner' from Xing. Again it runs smooth under 5.1.1 but not 6.0.1

---

I was able to reproduce the crash of PlayStore. Each time I try to localize my device from the PC by means of Android Device-Manager I get the messages "Unfortunately, Google Play services has stoped."

[Galaxy Tab 10.1 Android Development] decatf:
Camera works fine on 5.1.1. It does not work fine on 6.0.1.

That newspaper app needs permissions enabled through Settings.

What is the third app? I am not entirely certain which one it is.
[Galaxy Tab 10.1 Android Development] TerraD:
Thank you decatf. Your post gave me hope. So I installed today another 12 apps all of them did not show the problem I reported last week - I must have had an incredible unlucky hand to select those problematic apps for my test!

However I think there might be some flaw with the GPS: 'GPS data' almost immediately locks on 5.1.1. Inder 6.0.1 it needs minutes to lock and it sees only half as many satellites with weaker signals than on the second P7510 with 5.1.1. I'll investigate this on my own and be back later with the results. I think missing A-GPS data might be one the problems. I', aware of http://xdaforums.com/showpost.php?p=66657110&postcount=372 but this does not fit completely to my files.

Oh, did not realize this, as your thread starter post says: Camera, Pictures: working, Video recording: (not working). As this app reads barcodes I assumed this to be pictures not video.

Thanks, I'll try to figure out how to do it.

This was 'Tresorit' my encrypted cloud storage client. Very important to me. If I do not get it running it breaks 6.0.1 for me. They have a pretty responsive software development. If you can give me any further assistance on what causes the problem this would sure help to find a solution.

Thanks [MENTION=4404851]decatf[/MENTION] for your work on our outdated tab. Rom seems working fine with known limitations from op. Only thing i'm missing is the extended reboot menu. In earlier versions it was under developers settings but now i can't find the corresponding entry in developers settings. Am i too blind to find or isn't it implemented yet. Thank you very much for your hard work.

Thanks a lot [MENTION=4404851]decatf[/MENTION] for the Marshmallow build for our dated device!

Regarding the meaning of 'dirty flash' I'm wondering, whether it is possible to keep data and just wipe system, dalvik and cache? It would be really nice when there is a chance to keep data, as I've installed lots of apps (as I remember this has been possible when upgrading from KitKat to Lollipop).

Amazing you managed to cook this up! Well done!

I got stuck in TWRP though. I flashed TWRP but I am stuck at the Teamwin splash screen. It doesn't go anywhere from there. I was also a happy user of your 5.1.1 ROM. But now I am hopelessly stuck. I tried reflashing TWRP but to no avail. I managed to flash an old TWRP 2.2 which started, but that isn't very helpful. All 2.8.7.0 versions I have tried get stuck at the splash screen.

Any good ideas how to get some life back into my P7500?

Thanks.

OK, went back to stock. That seems to be the universal solution.

However, I am having serious issues getting Gapps to work. Booting up with the rom alone works fine, but as soon as I flash gapps (from opengapps) it is an endless stream of FCs. Anyone else with this issue? I tried several ARM 6.0 gapps packages but they all go terribly bad.

Any ideas?

found encryption works. I have installed the initial release, not download me the one in the downloads tab, and download the one in androidfilehost.

Asked simply charge the battery and once charged, encryption performed without errors. So far it works well.

A big THANK YOU in behalf of my girlfriend.

Her Lollipop build crashed yesterday on her p4 and I immediately flashed this build plus Gapps (had to chose nano version, others seemed to big).

Everything is up and running, a bit slow sometimes but thats fine for her. I donated you some bottlecaps so that you can buy 2 beer or 3 :)

Thanks for supporting this old tablet :)

[Galaxy Tab 10.1 Android Development] Guichinga:
What a surprise

My son had this tablet already retired and I was just asking him if he could hand it over to me to do some testing with it.

I grabbed the latest version available - surprisingly it was Android 6 which got offered, and did flash it after I recovered the tab from its deep unloaded accu behavior.

What I recognized after the flash is somehow astonishing and amazing! :cool:

The old tab is running pretty smooth on MM and most of my apps I did test are working well and fast. Of course there are some limitations available due to its technical specs, but it works pretty well!

The only issue I see and could not get fixed yet (despite it was somehow a topic within the old 5.1.1 thread) is the DRM issue Magine TV is showing.

It is referring to missing Widevine libraries. Maybe decatf might have an idea about the root cause, as I was able to find the files itself - moved them as listed in the old thread - but still the same issue - so moved them back again.

I was testing tethering with my Logitech BT keyboard, watching TV, WiFi and VPN and some others - and no FC or any other issue so far - after 2 days of testing experience.

Well done decatf!!! :good:
[Galaxy Tab 10.1 Android Development] powder_7:

The only thing is, some apps crashes without even starting, like the Netflix app. Is this known? And is there a fix for this?

Thanks for this great rom! 
[Galaxy Tab 10.1 Android Development] TauPan:
I think Netflix refuses to start because the device is rooted. Could be wrong, though.

Gesendet von meinem SM-G900F mit Tapatalk
[Galaxy Tab 10.1 Android Development] UncleDick:
Root has not been an issue with any applications that I know of. Video drivers, however, have been a nuisance for some time.

I tried several previous versions of Netflix from apkmirror (including 3.16, 3.9). All do the same thing as the current Netflix: Applications starts, red circle goes for a few seconds, then app quits and the message pops up.

This is the same behavior that Google Search and Chrome showed.

I was able to find a previous Chrome that still works on this ROM (49.0.2623 - there could be others, but I quit looking when I found this one).

Maybe there's a version of Netflix, but I'm not confident.

The aging video drivers seem (to me) to be incompatible with Marshmallow.

I cannot Flash this ROM

Hi, I am a little rusted about how to do this.

I have my P7510, Rooted, with 4.0.4 Android with IMM76D.UELPL Compilation

I wanted to upgrade to this, and I followed Instructions, but on reboot the tablet got Stuck, Thanks God I had made a Backup with CWM and was able to take it alive again

Is there a problem with upgrading from 4.0.4 to this ROM?

I'm 100% sure that WiFi tething was working fine in 2016-06-15 build, but it's not working in 2016-08-09. I'm just after clean flash to check it.

WiFi tething switch just flips back to off when I'm trying to switch it on and it then blocks WiFi switch in off position. To fix it I need to reboot tab.

decatf - do you have some hints or do you you recommend to go back to 2016-06-15?
[Galaxy Tab 10.1 Android Development] decatf:
Use the build that works for you. I might have missed something when restoring some wifi changes I tried in the July build.

I am working on Nougat now so I don't have time to switch back to Marshmallow. I will probably come back to it later but not any time soon.
[Galaxy Tab 10.1 Android Development] Technical:
For our tablet? Thanks :o
[Galaxy Tab 10.1 Android Development] vkmaxx:
If your working on Nougat then forget about it, it's more important as I can wait with previous build and then switch to Nougat when it's ready and the check/report if the problem is gone.

Diability

Yes we all appreciate your hard work :good: and effortless team in resurrecting our devices especially the orginal GT-P7510. Since my disability I was still on official ICS, since then I succeeded to root my device to 4.4.4 from youtube which lucky enough didn't brick my device. I have learned your forum and am very happy that I can at lest try to repair the damages. Unfortunately I also wasn't able to upgraded my device to the unofficial 6.0.1 which plaque this thead. I guess I can upgrade my device to jelly bean. and No I am not a IT engineer . THANK YOU VERY MUCH!
[Galaxy Tab 10.1 Android Development] Paul_Germany:
Updated to 6 today, wiped everything and installed the 3 suggested zips via adb sideload. Compared to the Lollipop ROM graphics seems to be smoother (kindle carousel), also some wrong notifications of USB OTG are gone. Some apps need a reboot to work properly, like Acrobat Reader.

Voice calls and 3G data work, Plants vs Zombies too, also a perixx BT keyboard including German umlaut and hotkeys like Alt-F4. Sound volume is a bit low. Some HD videos stutter like in the previous ROMs, here we have to blame the old hardware. Also the MS Office apps refuse to work due to the old Tegra 2, would be nice to have a patch.

Battery life is ok, I didn't use the tab much in the last years so it has not many cycles by now.

A big THANK goes to decatf for providing such a nice ROM

For what it's worth, TWRP 3.0.2 works fine on the p4tmo. Thanks.
[Galaxy Tab 10.1 Android Development] UncleDick:
TWRP 3.0.2 seems fine on my P4wifi as well. Found the new "reboot" feature interesting. After flashing the new TWRP, I pressed "Reboot" and after a bit wondered, "why isn't anything happening?" A closer look revealed that TWRP was waiting for me to specify reboot to..... System, Recovery, Download, etc. So, no more cramped fingers holding down power and volume up. Not sure if this is "better", but certainly different.
[Galaxy Tab 10.1 Android Development] jerryhou85:

Is there an alternative root method other than flashing SuperSU?

For example, phhsuperuser?

If I understand correctly, since sometime SuperSU builds have nothing to do with Chainfire anymore, and I don't trust yielding root access to my device and information to some unknown company- better an open source?

[Galaxy Tab 10.1 Android Development] jaibar:
Well, Apparently Chainfire sold SuperSU to a third party about a year ago. He himself posted something about it, and if I understand correctly, it was xda who introduced Chainfire with this company called CCMT or something like that.

CCMT, which owns SuperSU appears to be a little shady- you can look very hard but not sure if you'll find any privacy policy or anything like that. There are plenty of rumors- that it's KingRoot, that it's another chinese company that even chinese users don't trust, etc. etc. etc.

Myself, I don't care if it is a company from china or wallstreet- I trust Chainfire blindly without any doubts. Problem is, I just read that nowadays SuperSU has nothing to do anymore with the venerable dev, and I just don't like to trust my device's root access to a company that is not crystal clear about the things it can do with such powerful privileges.

Anyway, it's really off topic- enough has been discussed on this matter at xda and elsewhere. I was just asking if there is an alternative method to root this device.
[Galaxy Tab 10.1 Android Development] eushaun99:
Well if phhSU has a flashable zip then I'm sure it can root our tab. Anyway thanks for the info. Gonna do some reading on my spare time.

SuperSU

The SuperSU that dcatf recommends (and links to) is 2.52 Beta, from October 10, 2015 (the date on apkmirror.com)

Less than "a year ago", but not by much.

Rooting is not

required

to use this ROM. Of course, one of the benefits of installing a custom ROM is the ability to add all of the wonderful software that people have developed that require root (such as modifying CPU speeds).
