First task is now running on my Nexus 7, 2013 model.

The pictures / images under Status are a bit blurry, although that may be my eyesight. :)

nah, they are blurry, that's because the size limit (for the desktop client "Simple View") is enforced at something like 190 x 126 pixels --- which on most Android devices these days, which are much higher resolution will look silly.

Thank you for this app. I have it running on 4 phones. 3 are now doing nothing but BOINC. Motorolla Bionic, Optimus V, and a Vortex. (The last two must run nativeBOINC since they are not supported by Berkeley's version. They are Android 2.2) The last is my Galaxy S3 which is still in use but does sit on a charger a large amount of time through the day.

all of my tasks return as "no sensor" and fail quickly:

http://qcn.stanford.edu/sensor/results.php?hostid=32351
http://qcn.stanford.edu/sensor/results.php?hostid=32340

these are droid eris (2.3.7, oc to 710mhz) and incredible 4g (4.0.4)

thanks for getting this up and running! will you support usb sensors for android on raspberry pi?

Hi enginerd, the most likely "culprit" is the version of Android, since I relied on the newer Android NDK to cross-compile my C++ code (rather than the usual Android Java), you may need a newer version of Android.

I see on your HTC Eris they are Android
3.0.8-01625-g9d06ef9 :

http://qcn.stanford.edu/sensor/show_host_detail.php?hostid=32340

whereas my phone (Samsung Galaxy Note 3) is Android 3.4.0

http://qcn.stanford.edu/sensor/show_host_detail.php?hostid=32288

I'm not sure how these translate into the usual Android version names ie "Honeycomb" or "KitKat" etc, but is it possible to upgrade the Android version on these devices?

2 of your phones aren't doing anything, possibly because the hardware is V6 and not V7; another is crashing everything, and the 4th seems to have been running the same task for a few days.
It's possible that the OS is too old on the last 2 mentioned.

And there's no point in attaching every computer that you have if they don't have a sensor.

unfortunately verizon does not release many updates for their devices. why make an existing phone actually function for making phone calls, when it's so easy to just purchase another expensive device before the 2 year contract is up? :|

the Eris (android_8402ea16, computer 32351) is likely too old. that one's on 2.3.7.

the incredible 2 should be better than that though:

android 4.0.4
htc sense 4.1
kernel version 3.0.8-01625-g9d06ef9

any guidance on what minimum Android (kernel) version is required? I'm thinking about jailbreaking this thing...

I'm not sure what the minimum version is, my Samsung Galaxy S3 is getting on two years old and that seemed "new enough" from the usual updates (I usually just use it as an MP3 player at the gym -- and for testing BOINC/Android/QCN now at night). I guess an Android 4.0 version (e.g. Jellybean, Kit Kat, Ice Cream Sandwich) would suffice? My S3 says "Android 4.3" and "Kernel 3.0.31 11/28/2013" -- so I guess it's automatically fairly up-to-date via wifi.

Also the Eris is a V6 device. This app probably only works with V7.

My tablet was upgraded from Jelly Bean 4.3 to KitKat soon after I got it.
I just had to approve the download and wait a few seconds.

It does seem VERY sensitive to the slightest vibration though. Probably needs to be on top of a concrete pillar going down into the ground, rather than a table sitting on a wooden floor.

When I remember it, I'm going to get a piece of thin foam rubber to rest it on.

My workunits on my phone ended up reporting "Too many resets" and "Too many total results". How can I deal with it?

Sorry for my poor English.

Any idea why this host http://qcn.stanford.edu/sensor/results.php?hostid=32387 crashes each workunit?

- Samsung Galaxy Tab 3
- Arm v7
- Android 4.1.2

my guess (for a crash after a few seconds) is it probably needs a newer version of Android, I used a recent Android NDK for development which was needed for the accelerometer library.

For many resets - the device probably can't support the high number (50 times a second) of accesses to the accelerometer -- QCN should then try a lower rate which will cause fewer resets.

I think this is not the reason. The system which has the newer Android version crashes the WUs while the older Android runs them.

This system crashes the WUs
http://qcn.stanford.edu/sensor/show_host_detail.php?hostid=32387
Samsung Galaxy Tab 3
Android 3.4.5-1272676-user
ARMv7 Processor rev 0 (v7l)

Here WUs are running well:
http://qcn.stanford.edu/sensor/show_host_detail.php?hostid=32388
LG Optimus 4 hd
Android 3.1.10-g0ab41e4
ARMv7 Processor rev 9 (v7l)

Could it be, that the Samsung Galaxy Tab 3 hasn't an accelerator?

Thanks for the update, it's nice to know the "older" Android is running at least. If there is no accelerometer then it should simply just say "Not Found" and not crash. Signal 8 (the error you're getting) is a "Floating-point exception" but that doesn't really make sense. I'm pretty sure the Galaxy Tab 3 must have an accelerometer anyway (I've tried it with the "2014 Edition" Galaxy Tab and it runs fine).

Doing a bit of poking around, it seems that Samsung has several Samsung Galaxy Tab 3 models, with a variety of sizes. I've seen mention of 8 inch and 7 inch, and there may be more.

So, Yoyo, could you please tell us which one you have in terms of size and when it was bought. There may be other "distinguishing marks" as well.
Or, does any of the documentation with it mention an accelerator?

ok, well >1000 resets will cause that ie QCN just quits. If the phone is throttled down to .2 seconds between readings (a 5Hz) sampling rate) versus our usual .02 (50Hz), and still resetting so much, it probably isn't going to be useful running QCN.

I'm not sure what the minimum version is


The Play store page for BOINC lists support for Android version 2.3 and up.

It is very new, bought it a week ago. It is a 7 inch Tab with GSM module.
