Hello guys, i'm an experienced BOINC cruncher with many WU under various PC/smartphones. Here goes a big problem: i've added every project available on BOINC for Android and i can't find WU to calculate. Zero. Nothing to nothing. Some years ago, were some projects active for android from World Community Grid, but now they have nothing for Android.

The question is: why there aren't, in so much projects (i tryed WCG, Einstein that seems completely dead about login, SETI that seems dead too about login, Asteroids, LHC home etc.) WU to calculate? i have this phone that can operate 24h on 24h but there is nothing to do in months. I'm wondering if adapting projects to ARM is extremely hard/time needing or if just no one care.

Here are my specs:
- Android 8.1 phone with 8 ARM Cortex-A53 cores and latest google play boinc version.

I bought an Android 9 tablet earlier this month, so I could join in the testing. I logged in to both SETI and Einstein with no problem at all (didn't try WCG). SETI's applications haven't kept pace with new developments in the Android landscape, and all the tasks I've been sent have failed. But Einstein has been sending tasks, and the tablet has been returning them, consistently.

Specs are at Einstein host 12798421

Edit - when you say 'latest google play boinc version', can you put a number on that? You'll see from the link above that I'm running the test version 7.16.3

Sure. BOINC 7.4.53. I don't know, i can't login in Einstein and SETI from app, it just return weird errors like "wrong password" or "impossible to connect", even when i can login with no problem via PC.

I got my v7.16.3 from APKMirror - I'm sure other sources are available.

Are you sure your phone's Android version is fully up-to-date? There have been developments since the days of v7.4.53, such as more projects requiring support for SSL (https).

Why there isnt, on play store, the latest version? where i should find the official source a part third party apk website? isnt this paradoxal? The latest version available (from pc browser, so not a phone limitation) is the one i have installed.

Because v7.16.3 is still in testing, still has bugs, and will be replaced soon by at least v7.16.4

But it works better than yours appears to work currently, so it might be worth a try. I'm told the play store has a beta access route, but a quick Google / APK search worked better for my needs.

Uh ok, thanks a lot Richard, very kind. Ill try the updated one.

Oh wow, its infinitely bugged, it keeps crashing all the time, cant do nothing. Maybe ill try some previous version.

Tried with 7.14.1 (the .6 just crash after login) and no works available. Now i can login to einstein (at least), but still no works, no WU.

Moreover, the problem with Universe@Home is still here: if i try to log-in, it just says wrong password. If i set "forgotten password" from PC on the official website, it says "the account dont exist". If i try to register (still from pc browser), it says "the account exist". So, RIP Universe@Home, i suppose they have log-in problems....i don't know. Impossible to register, impossible to connect, from smartphone or PC, from boinc app or from web browser.

That's what other people report as well, thus a project problem, not BOINC.

SETI's applications haven't kept pace with new developments in the Android landscape, and all the tasks I've been sent have failed.

You probably have a 32bit Android version running on a 64bit CPU. As with all Unix/Linux derivatives this requires that 32bit compatibility libraries are installed, something that you cannot do on Android (unless you root the device, and install a custom ROM).

Eric has been promising that he'd look into this for the past 3 years, I'm not keeping my hopes up.
You can check what bitness your Android has by installing AnTuTu Benchmarking -> My Device -> Android

Yes, ok, but the other projects send nothing. 0. Pretty curious.

You probably have ...

Don't think so - I think I'm savvy enough to watch out for things like that.

The error messages I got at SETI were all of the form

"../../projects/setiathome.berkeley.edu/setiathome_8.00_arm-android-linux-gnu__armv7-vfpv3d16-nopie": error: Android 5.0 and later only support position-independent executables (-fPIE).

I didn't hang around long enough to see if the server would eventually send me any of the pie apps they have installed.

Ideally, the server plan class spec should know already that Android 9 excludes non-pie apps.

ARMv7 apps are 32bit, ARMv8 are 64bit.

BOINC on Android sends you (for Seti at least) 32bit apps if your OS is 32bit. It doesn't care that the CPU is 64bit.

Well, I've searched the tablet itself, developer mode tools, the shop blurb, the Samsung UK blurb, ... none of it says 32-bit. But none of it says 64-bit, either. Bother.

OK, what do we know about pie / nopie, then? That's what the error message said - nothing about library bitness.

Edit - the Einstein server reports

2019-12-18 17:46:40.8721 [PID=23677]    [version] Best version of app einsteinbinary_BRP4 is 1.46 ID 643 NEONPIE (3.05 GFLOPS)

, and the successful (valid) tasks report

Application:Binary Radio Pulsar Search (Arecibo) v1.46 (NEONPIE)

SETI has a v8.00 (armv7-neon-nopie) and a v8.00 (armv7-neon).

Why did it send me v8.00 (armv7-vfpv3d16-nopie)?

Thanks. Confirms 32-bit (sideways - won't switch from portrait to landscape). So armv7 is right - any thoughts on pie?

In the end it doesn't matter as they all err anyway.

As for pie, you wonder why you're getting the non-position independent executable over the position independent executable? I don't know. Perhaps that your Android internal kernel number confuses BOINC/Seti server. I've had it a couple of times off late that applications I have had installed for absolute ages all of a sudden tell me I need Android 5 or higher to run their app. I have Android 9, but kernel 4.9.148

I see yours is 4.4.111, so perhaps that that confuses the Seti scheduler. I don't know, you'd have to ask Eric on that.

And I'm sorry, wasn't ignoring you, but I don't know the answer to your problem. Don't stare yourself blind on the titles I have, they both mean just that I can do a little more to battle the spammers on these forums than e.g. Richard can. It doesn't mean I am anything official in the development of BOINC.
