[Q] Device diagnostics (benchmark/stress test) - Java for Android App Development

Hi guys!
I'm starting a company in Brazil similar to Square Trade and Asurion in the US. So, before a user signs up to one of our protection plans, we need to remotely verify whether the device is fully functional. We already have and app that does part of that (the user takes a photo, press some buttons and does some other activities so we can verify the device).
However, there's still some terrain to cover. I was thinking about a stress test that would make the device freeze/reboot when the processor/board is faulty (like these devices do when people try to use heavy apps/games), some network tests (wifi and 3g/4g) and battery tests (Android already reports some stuff like health and temperature but I think these are not reliable). Do you guys know about some way to do that? I searched for an open source benchmark engine to no avail, so the next step was to ask here given you guys are always making awesome software/tweaks.
Any help is appreciated.

[Q] Samsung Galaxy Nexus GT-i9250 Pinout

Hi,
In our current research, we want to measure power consumption of an I9250 doing various network related tasks. To do this, one of our electronic wizards must connect his instrumentation tools to the battery pinouts. He told me he needed to know the resistance of the two extra pins (those two except + and -)
Anyone who knows this, or has done something similar?
Best wishes,
Morty
So as I understand it those are not used to provide power for the battery. These other pins are used to communicate with the battery (and if it has NFC) use the antenna embedded into the battery. Your engineer doesn't need to do anything with these but connect them straight to the phone.
Out of curiosity is your research going to get published anywhere? I am really interested in those types of numbers
Hi thanks!
We did similar test on the Nokia N900. For this phone, we had to add resistance to the third pin (the additional to + and -). The results are not published, it was part of a master thesis for one of our students.
The experimentation with the nexus is also part of a master thesis, as always we hope it will end with a publication! We can then provide some results.
Well I don't understand why they need to do anything, if they pass these straight through and tap the power lines the battery should work fine (appear transparent).
If that doesn't work then you have two options. The first thing is to buy a replacement battery and take it apart. The second would be to go into your lab and use a scope/meter to measure those lines and see what they do.

Could this be the cheapest 'proper' smartphone watch?

...by 'proper', I mean 'standalone'!
Basically the same as my old Vapirius AX (similar to Rock/Z1) that I've used daily for 2 years, but much cheaper and runs Android 4.1 and it has 320x240 2'' screen and not the square 240x240 1.5'' style of most watches which I can't get on with.
I'm going to order it and check it out. .
Nothing to lose at that price!

Wearable Smart Phone Watch AN1 2.0" Touch Screen Android 4.1.1 w/ Camera / Wi-Fi - White + Silver - Free Shipping - DealExtreme
Looks like the Neptune Pine...
The AN1 Reviewed (I Think Comprehensively)
Here's what you need to know about the watch, which I've used for several days. It's more a sweet novelty than a gadget of genuine use. But it works. It's basically a mini-tablet phone (or phablet) and functions via the exact same Android protocols, except the master controls are hard, physical buttons built into the left and right sides, rather than soft touch-buttons on or below the screen. And of course the interface is configured to adapt to the tiny size. Yet at two-inches, that screen is a bit big for comfort if you like wearing the watch face on the inside of your wrist (which I do). So I sometimes rotate it to switch position.
Touch sensitivity seems excellent, as well as touch accuracy, which is hugely important given the minuscule QWERTY keyboard that pops up when you need to enter text. Unlocking the startup screen is frustrating at first until you figure out that you have to swipe the icon up or down, not to the side, as on bigger screens. There's no icon or hard control to access the active-apps screen (from which you can toggle back and forth between active apps and turn running apps off); as on certain larger phablets, you get to it by long-pressing the home screen button.
Because the AN1 is small, its WiFi receptivity is modest (the signal is strongest the closer you are to the source). So's volume but it's not bad for the size. You won't hear much through the earphones except in relatively quiet places, unless you have a separate sound booster; but in quiet places it isn't bad. However, it's impossible to attach the earphones one-handed; at least it is for me: You have to hold open the protective soft plastic flap that covers the mini-USB port (which is where they attach), which means you can't wear it while setting that up. That said, the AN1 will also transmit to Bluetooth headsets. And video/audio playback is very smooth. Even impressive, all things considered. Not a gamester, so no idea how gameplay would go. But with a two-inch screen, why would you want to?
Believe it or not, eBook reading is also a very decent experience in either the page or landscape aspect, though for simple eye-to-text positioning, page view works best if you take the watch off and operate it two-handed. In landscape view, though, you can make like **** Tracy. The only reading app I've tried so far is Amazon Kindle, but every feature seems to work per normal. Whatever normal is at that size.
No problem with the phone detecting a SIM card or storage-expansion microSD card (I added the 32G max, which costs all of $10 on eBay). But the cards are tricky to insert, because the lock flaps that secure them in place are so flimsy. However, once they're in, they're in. And insertion of the expansion card is critical, since the Internal Storage provided is write-protected; you won't be able to download (via internet) or sideload (via computer) files or apps without providing extra storage.
The battery is built into the back cover. Comes the time when it no longer holds a charge, one would need a replacement cover. I assume those are available or will be made so eventually.
There's no Playstore app included; plus it's futile to sideload-and-install Playstore from another source, since the app quits as soon as it boots. There is instead the HiMarket app, whose store features mostly Chinese text; but if you know the apps you want/need, you can still enter a search in English and find them -- most of the time. Sideloading and installing other apps also seems to work -- most of the time.
And oh, yeah -- in the "Good safety tip, Egon" department -- don't wear the AN1 (or any other Android watch of similar concept) in inclement weather. With an exposed speaker grille and exposed miniUSB access port (the protective flap doesn't fit snugly), not to mention hard buttons that aren't part of the case proper, bringing this out into very moist air or, worse, active precipitation, would be like putting your iPad in a filling toilet tank to see how high the water has to go before it fries.
Not encountering anything much in the way of buggyness yet. All in all, the AN1 does precisely what it claims to do. And for the conversation-pieceness of it, and frankly, the satisfaction of my curiosity, I'm happy to be an owner. It won't collect dust. But it's not for the customer looking for significant enhancement of his electronic life beyond what he already has.
Thanks for the review.
Also been using the AN1 for a couple of weeks and fairly impressed, but then I've been wearing a similar one for a couple of years and have only that and a conventional phone to compare it with.
Confused what you say about the battery; my AN1 has a battery on the back that can be detached and changed by pressing a small recessed lug/clip. The battery is the same as the old Z1/Rock/Vapirius so is readily available. Are you sure your battery is non-removable?
Also, as it's rooted - although Superuser is not installed - all current Play Store and Google services, sync adapters etc can be side loaded into system/apps, changing permissions the usual way. I am running all the latest Google App stuff now, but you're right about the Chinese Market and I removed it immediately along with anything Baidu related.
My only mild criticism of the watch (I can live with the floppy USB port cover as most mobile phones have no cover whatsoever) is the screen, not the digitizer which as you point out is responsive and works well, but the outside screen. It's scratched badly already and cleaning it makes it even worse. It's almost like a bad plastic. My other smartwatch has been used every day for two years and the screen still looks brand new without protection.
Lesson is get a good screen protector BEFORE even touching it! Although is fairness, the scratches don't really show when the screen is powered.
The sound can be tweaked in the engineering settings (I've forgotten the number/symbol sequence to access those settings right now) and I have managed to get it sufficiently loud to annoy other people listening to a phone conversation.

No. The AN1 is running 4.1.1. The older Vapirius watch I mentioned is running 2.1.
with the z1 smartwatch / Vapirius they stopped with the clean rom I would like to see a custom rom for this :fingers-crossed:
I found this clone of Galaxy Gear and it's even cheaper at $85.99 !?

This isn't a Play Store compatible device. Also, looking at the pictures, the apps are proprietary.
Some Android devices, especially Chinese ones that I've used, Google Services aren't installed and have been done so manually in order to get all the Android features.
This isn't one of them.
I can give the firmware for the AN1 if someone would like to make a custom rom.

Shame hey.
All those sensors are useless if there's no app for it.

They've caught on to a great idea, but it seems pretty pointless as said before. Hopefully there will be some improvements in the (less expensive) range of android wear.

with the z1 i used gapps install zip and gapps copy zip.You guys that have the AN1 do you have these for this watch or can you point me to the place to get them.

Details on how to load all the Google stuff onto the AN1 and most other similar Chinese devices are here (reply#7):
http://linuxslate.com/cgi-bin/forum/YaBB.pl?num=1399895851
These are the steps:
Here are my instructions for putting all the correct Google Play stuff and thereby having a full non-Chinese Android. Remember to totally uninstall all the Chinese Market and Baidu.
Download the files from here:
https://www.dropbox.com/sh/56ppcal1t9dwm6g/AACubjVgwQIcFjVv0_wvo05na
1. Use Root Explorer
2. Copy GoogleServicesFramework.apk, GoogleLoginService.apk and Google_Play-v3.8.17.apk to the system/app folder on your phone with Root Explorer.
3. In Root Explorer click Mount R/W. Change the permissions of the 3 files to match the permissions of the other files in the folder rw-r--r-- (6-4-4). Then click Mount R/O and exit Root Explorer.
4. Install GoogleCalendarSyncAdapter and GoogleContactsSyncAdapter the usual app way.
5. Reboot your phone. Hard reset is not necessary.
6. Go to Accounts & Sync in your phone's settings, click Add account and enter your Google/GMail account details.
7. Go to your apps and Launch Google Play.
8. Update any Google stuff from Play Store if prompted.
I'll do a vid of this sometime.
Good luck!

AN1 Battery Clarification
Hey, Marcus -
Sorry to take so long to reply.
When I said the AN1 battery was non-removable, I meant that the back of the AN1 watch IS the battery, for all intents and purposes, and is the battery housing, not a mini-case into which a battery could fit. Yes, as you say, it's removable via the lug-clip and that gives you access to the card slots. But I didn't know one could buy a replacement; the lug-clip architecture is so specific to the watch build that I thought an AN1 battery replacement would have to be sold as a locked-to-the-model accessory. (Well, until today; trolling around eBay I saw a Z1 battery/back panel replacement for sale and kind of assumed it would fit the AN1. But it was $39 which struck me as high, so I didn't purchase. I'll do a broader search for Z1 replacements now, though. If you know of where they can be gotten cheaply, chime in.)
No Real Need for Rooting
By the way ...
Even though the AN1 isn't Play Store compatible, I've been able to load everything on it that I need. I either find direct links to download the APKs desired, or APK store links that bring me to the APK. In any event, sideloading from my computer is easy, then I just use File Manager to open the apps. If the apps don't work, I uninstall them. Most of them do. And there are so many choices that you can eventually have it doing everything you desire of it. (Beasr in mind, it's not really practical to install anything too unique or fancy on the watch because of its screen size; it's best for basic utilities that let you play videos, read books, manage calendar data, email, facebook, etc. And it does all that handily. Sometimes not with apps that work on your larger Android devices; but it doesn't take much time at all to find something that'll do the job as well in miniature.)

[Q] Looking for a more reasonable 'phone' (dialer) app...

Ok, I'm around day 5 or 6 of trying to get my new Samsung Galaxy S-5 to be 'ready for prime time'.
[ It isn't. ]
I'm NOT new to Android (I own a Nexus-7 and a Nexus-10...oh, and a TV-dongle, too.)
And, I've developed a couple of apps (I use Android Studio, on my laptop), and
Eclipse before that.
And, yet, this new Galaxy, being my first SMART phone, is putting me into mumble-mode, with
all the svc-stoppages, and crazy behaviors that its 'phone' app is exhibiting.
Ok, my phone app is the 'default'...iirc, it is called 'phone' and has a green background with a
white pic of an old telephone hand-receiver on it.
The sub-optimal behaviors list of the app includes:
(1)It has decided to allow screen-rotation, but I don't want it to, as I am not (yet)
planning to use a headset or earpiece...at least not full-time.
(2)Even worse than rotation, it sometimes totally blanks the screen during rotations...not
sure if that's a bug or just a side-effect, but I didn't want that anyway.
(3)Not even sure I want it's numeric keypad to EVER go away, but when I perform other
actions, e.g. choose 'recent', then ok..makes some sense for it to discard
the keypad to get more screen real-estate for those ancillary use-cases.
(4)The biggest defect, seems to be that, after I complete a call, and I press
the red 'end-call' button, next thing I know, if I then carry out other use-cases, such
as hitting 'Recent', checking a few things, and then hitting the 'go-back' button
(at the bottom-right now, that some side-effect often kicks in, and my
phone decides to go off and make a call to the most-recent person that I
talked to. I respond with one or two 'go-back' button presses, and then I may
see a popup saying "whoops...some 'svc' just died/crashed". [The fourth or fifth
time that happened, I had to hold-down the small button on side of the unit, and
choose 'power-down' and shutdown/reboot Android, to clear out the stacked
operations that it seems to want to re-invoke. ARGH...
Bottom-line...I want this phone' app to mostly behave with mindset of how a 'not-as-smart'
flip-phone works...as though the numeric-keypad are hardware-keys, and don't
try to out-think me. i.e. When I take the phone away from my ear, to see the keypad
in order to press a key, do NOT blank the screen and do not rotate, etc, etc
Ok, some some reasonably-intelligent tech suggest that, maybe, I could find an
alternate app for 'phone'...i.e. she suggested that I go to the app store and serially
find and install alternate 'dialer' apps, until I find one I like better.
[ She then demoed a phone running M$'s tablet-OS, and I gave it a plus-one
for being smart enough NOT to rotate it's layout when I rotated it with its
dialer active. But, no, it's gonna be either Android or go back to a flip-phone for me. ]
I retorted that I'd rather find some list of 'most-popular' alternate phone-apps for
Android, so that at least I could try out alternatives in other than a random-order.
Anyone 'been down this road', that could advise me how to proceed?
[I tried disabling 'screen rotation' but that is global to ALL apps, which is NOT
what I want. I want ONLY that one app to quit rotating...why isn't that already
an app-specific setting, under its "three-vertical-dots' icon?]
EDIT: Oh, by the way, who signed-off on defaulting to this 'phone' app?
Google or Verizon (or some other company)?
[ So as I'll know whose stock to sell short. ] :laugh:
Ok, making phone calls just isn't ready-for-prime-time yet
Even after several more days, no one at a couple of different Verizon stores could come up with
satisfactory workarounds for the 'Phone' app's bad behaviors.
And, meanwhile I noticed several more negatives with trying to make a 5-inch 'phablet' meet
my needs. Such as:
(1) On day 1, the "Otter" holster that I bought with this Galaxy got snagged as I was getting
into the car, and broke the clip. (Luckily, that vendor gave me a new outer-frame w/clip, no
questions asked.) But, the seat-belt covered it which wasn't comfortable. And, when standing,
with the phone horizontally on my left-front, I couldn't even bend down comfortably, to stretch
or when exercising, etc.
(2) On day 3, I happened to need to lie down under a kitchen sink to make a minor repair,
and the only way to be comfortable, was to completely remove the Galaxy from my belt
and lay in on the counter. Whereas, the flip-phone that I've owned for the last 5 or more
years, comfortably has NONE of those issues...I never have had to remove it, in any of
those situations.
Long story short, I have now returned that goofy too-large-to-wear 5-inch phablet, and
upgraded to a brand new LG VN170 FLIP-PHONE, that works just like the flip-phone
I had (so there's nothing that I am required to learn to use it), yet it has lots of new
software features and subtle improvements over the LG VX6300 that I'm replacing.
Note: I strongly considered Google 'Glass' for quite a long time. Conceptually, that
product is closest to my needs (now that I understand them better) !
So, to summarize:
Flip-phones rule (for low-cost portable/wearable devices to make phone calls with) !
I love my 7-inch Nexus-7 Android tablet, and will continue writing apps for Android.
[ More than enough said? ]

[Q&A] Tegra Note Discoveries

Q&A for Tegra Note Discoveries
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer.
Before posting, please use the forum search and read through the discussion thread for Tegra Note Discoveries. If you can't find an answer, post it here, being sure to give as much information as possible (firmware version, steps to reproduce, logcat if available) so that you can get help.
Thanks for understanding and for helping to keep XDA neat and tidy!
I think I read through this entire thread a couple of days ago, but dont think I saw this little 'Gem' posted here.
I saw somewhere (maybe this thread) the multi-click enabling of some kind of Diagnostics function when
you multiple click on 'Settings/About Tablet/Kernel version', and you get the diagnostics dialog (much
like enabling Developer by clicking on Build number).
The new (at least for me) is multi-click on 'Settings/Android Version', and you get a little easter egg, first time I
did this I got some kind of game (I think, I dont play games), 2nd time, I could not remember what additional
things I did to get into it (there is something after the red screen).
OK, got back into the game screen again but still not sure how, you've gotta click about the screen at random.
Mobile Network setting missing?
My friend just received a Tegra Note P1640 Advent Vega running Android 4.4.2. It's stock, not rooted at all. She wants to hook up her Sierra 313U USB modem so she can get on the net with it, but for some reason Mobile Settings is missing from the SETTINGS app.
I know that this Tablet does not have a SIM card slot, so maybe that's why it's missing. But hopefully there is some way to activate it again without having to root it.
Here is what is listed under Wireless and Networking:
Wifi
Miracast
Bluetooth
Data Usage
MORE
And this is what is under MORE:
Aeroplane Mode
VPN
I found this app in the Google Play store, but that is only a shortcut. So if that Mobile Network setting is not activated, I doubt it will work, or will it?
https://play.google.com/store/apps/details?id=diewland.settings.mobilenetworks&hl=en
What do you suggest? Is there any way we can access the Mobile Network settings so she can use her Sierra USB modem without having to root it?
Tegra Note 7 Hardware Teardown Tutorial
I have been looking on the internet for quite some time now but I have not found a sequence of images or video tutorial on how to disassemble a Tegra Note 7. I only found one post on the XDA forums by member "e8hfff" that said "Tegra Note Openned" but with no images visible. Could someone provide some insight on how to properly disassemble the table?
The reason I am asking is that my TN7 is past warranty and the battery has sadly seen its last days. I have enough knowledge about Lithium Ion (smart and dumb) batteries and the confidence to fix my issue, but I am uncertain how to properly take apart the tablet, not wanting to risk damaging the components. Any advice from someone who has done this would be greatly appreciated. Thanks!

Just as bschles above, I too would like to request info on Advent Vega Tegra Note 7 disassembly.
I've managed to insert my SD Card incorrectly and cannot remove it, it is stuck inside the machine with nothing protruding to get a hold of so I cannot remove it. I would like to remove the casing so as to access the card and extract it, in some other thread someone said they can open casing with just their hands, question is 'HOW' ?
I have tried pulling and pushing and squeezing and twisting, all to no avail. With my eyes, I cannot even see where the joins are and so not sure where I should concentrate the effort to separate the case parts.
I have tried searching internet/youtube for any TN7 teardown without any success (although another thread in this forum has several pics of inside of machine) and would be grateful if someone could point at a video link or explicit instructions for
dismantling the case, then I would be able to extract the stuck card and access the data on it. as it is, I can neither remove nor insert for SD card access leaving me a little lost for what else to do.
Perhaps some kind of video submission would not be out of place in a forum dedicated to such a wonderful little tablet.
I'm kinda feeling that my only recourse to access data on SD card is a two pound hammer.
Any assistance would be gratefully accepted.
Thank you in advance.
EDIT: Link to above mentioned on-site pics of TN7 internals:- http://forum.xda-developers.com/showpost.php?p=55877787&postcount=7
Further to above:
I finally managed to get the case open.
The join lies about 1mm behind face of tablet, need to squeeze in your thumbnail and zip it around the whole of the machine
where you may hear clicks as the catches are undone.
The end furthest from ON-OFF button will be most difficult and last to release. Take care not to lose the on-off button and
audio up/down rocker as you struggle to free the case back. It took me about 25 minutes (at least) to free the case back
the first time that I finally figured out where to separate it, opened it a further few times in a lot less time.
Unfortunately, once the SD card was removed and re-inserted, it continued to fail to be detected and trying anther card
also failed, so looks like I need a new tablet although I can still continue to use this one without external card.
Anyway hope above may assist someone else if they suffer similar difficulties.
NvCPLSvc problems
I noticed that after upgrading to 5.1, the process "com.nvidia.NvCPLSvc" is constantly on top of CPU usage list, and if I turn on the "Show all ANRs" in developer settings, it shows message that this process (Nvidia Tegra Services) is not responding, killing it helps for a while, but than again, it shows up and system says it's not responding.
After killing this process system works faster, no heating (before this, my tablet reached 42 degrees even if I just listened to music in headphones with screen off...), and games doesn't lag as mush. Also no other crashes experienced by me so far.

Help to reprogramming of temperature data loggers - TempTale 4 USB

Foreigner here, please be kind =)
Hello everyone, good morning, good afternoon and good night!
Recently I have received some orders for laboratory supplies accompanied by a temperature Datalogger that performs the recording and storage of the temperature history for 11 days.
I've been researching the model and it is for single use and disposable (TempTale 4 USB - Dry Ice version by Sensitech)
I also discovered on some foreign websites that although there is software from the manufacturer to "unlock" the device for later reuse, the acquisition is not compensated due to the low value and the existence of other reusable models of the brand itself (Sensitech).
As this model came by surprise in my hands and no one has other uses for it, I decided to disassemble it and analyze its hardware. It has an Atmel controller that in my opinion could be reprogrammed to reset the programming or even unlock it for other uses.
If possible, I would like to count on the help of experts here on the forum for this. I believe I have come to the right place for this!
I leave some internal and external photos of the device for you guys

It is worth mentioning that it has an interesting system that when connecting to the computer automatically generates a pdf report with all the data and graphs of the temperature record and another .ttx file that I still don't know what it is. Both are also in the drive folder for you to look at.
Hello there, your thread is kinda old by now but I am working on this myself.
Unfortunately I cannot provide you with the software for Sensitech dataloggers due to it being a bit risky, I do not want to get into legal trouble with Sensitech or getting fired for a hobby project. However even with the software you won't be able to reset one without somehow altering the chip contents. It will give you an error message that the dataloggers are meant for one time use only and cannot be reprogrammed.
The way to reset them is to manually erase the content of the ARM chip on the board, I don't know much about microchip programming but I have gotten it to work myself completely by accident. Probably by measuring each pin with an oscilloscope probe I have somehow corrupted/erased the programming on this chip. After that a red light started blinking and the word SET appeared on screen. After that I was able to reprogram them.
The TTX file is a more detailed database of the temperature logs, from which you can extract CSV files and do some sort of fancy graph displays and all that. The PDF is just for general overview.
You have a different model than the ones I get though. I have found that by shorting the Winbond chip and rebooting the device (shorting the battery connector briefly) it goes into some sort of error state. The screen will blink and every time you press Stop the actual temperature will be displayed on the screen. I do not know if your model has this too.
Is anyone still working on this? I have an interest in discussing repurposing a temp tale and would like to discuss
