Android app release: feedback thread

Is this project currently

Is this project currently having missions for Android users ? Because my Android phone always says that "waiting for tasks". Does anyone have the same situation like me or my Boinc app has some trouble. Thanks for your help !

Also, my English is not good since it's not my mother tongue:(

My Android still is getting

My Android still is getting tasks without any issues, so it must be something on your side. Please post the event log from a work request, usually there should be some info on why you don't receive any work.

Please (also) check your preferences and make sure you're not filtering "Binary Radio Pulsar Search (Arecibo)", e.g. by selecting other apps while not allowing "non-preferred apps".

OK, thanks, than they will maybe fix it soon.

Not yet a fix but a mitigation: we separated the Intel GPUs from the Android devices (BRP4G vs. BRP4) for the time being. That should get rid of the cross-validation issue. Fixing the root cause (numerical accuracy differences across compilers/platforms) will take some more time, further complicated by the fact that we current don't have access to an Intel GPU test rig.

Stay tuned...

That are good news, that

That are good news, that should eliminate all the invalids for me. Thank you.

 

EDIT: I see this has been announced just 4 days after my post, that explains why I didn't see any new invalids and inconclusives since couple of days.

'Binary Radio Pulsar Search (Arecibo) v1.51 (ASIMDPIE_1X)'

Tasks run without problem but after 100+ tasks it seems that only about one fourth of the completed tasks will be successfully valid.

I thought I'd give an update on this case now as this phone reached 6200 total credits which means it has succeeded with more than 100 validations so far (crunching with 1 core only).

Successfull validations have been much more common for this phone after iGPU tasks were separated in their own league. Currently it looks like about 2/3 of the tasks validate succesfully. That makes this search interesting enough for me to participate in, so I'll let this android supercomputer continue running these tasks. For a long time I was only able to see this 'Binary Radio Pulsar Search (Arecibo) (BRP4)' listed among the searches and some times wondered how widely exactly has that search been running in the past. I'm able to participate in it now (just a tiny amount... but it's fun). Great !

So... Thank you Oliver, Bernd (and other project personnel) for making those changes on this search.

Hello all, recently i ran

Hello all,

recently i ran into an issue and was able to find a workaround, i leave it here because it may be useful for other people.

 

I own a Sony Xperia Z3 and use BOINC Version 7.18.1 with multiple Android OS Versions

Android 6.0.1 -> works

Android 10 -> works

Android 11 -> fails with message

Error while computing (in browser)

fdsan: attempted to close file descriptor 9, expected to be unowned, actually owned by FILE* 0xa89dd060

see task https://einsteinathome.org/de/task/1259778497

The application displays "Berechnungsfehler" after downloading a task and wont continue or retry the computation. For me it seems this is a pure operating system issue? To fix this problem i had to downgrade my operating system.

I've tested the application on Sony Xperia 10 II on Android 11 and Sony Xperia XZ Premium on Android 11 without any problems.

 

 

Another issue i encountered was that the task where enqued for downloading, but did not start to download. There are options to "reset" / "Zurücksetzen" a project, this cleared the current download queue, but still ended in a new task queue which does not download. I fixed this by completely removing the application and make a clean install.

 

nice regards

Thanks for bringing this up!

Thanks for bringing this up! We had fixed the issue over a year ago but apparently merged it into our production code after the initial tests. That means newer apps don't contain it anymore - duh! We'll work on that right away.

Stay tuned,
Oliver

This wasn't an issue with the

This wasn't an issue with the app (we already fixed over a year ago) but with our app selection filters and you specific device. That's also the reason why your other devices didn't experience any problems.

We fixed the filter at our end and your device should now receive the correct app (1.51) on the next request (running Android 11).

Cheers,
Oliver
