What about that power? See how much power they have. Do you really think that "all" Android devices have low power? Starting from 2015, every brand has his top device with a powerful CPU and imagine how much work everyone can do.

The "problem" is not just the power. Is also the requirements to start crunching in a device ( ej over 90% battery and plugged) This could cause that some devices will compute just few minutes.

Also, our priority is a stable version for computers and later the android and ARM(Raspberry pi ) versions.

Best regards, Joel.

As noted before, taking advantage of various ARM optimizations would benefit an Android app. It's no different than taking advantage of optimizations on Intel/AMD chips.

Right now, on a 2nd gen i5, your WUs are currently less than 4 hours with a one week roughly deadline. Assuming a WU took 3x longer, that's about 12 hours... so that deadline still doable in a week even in a limited time on ARM devices, even 4x longer / 16 hours. That's allowing for 4 hours of computation per day.

Being plugged in is pretty much a factor of all DC projects on Android. But computers are plugged in, so... :)

That all said, if it's not critical WUs be returned in a 1 week timeframe, you can adjust out the deadline. Might I suggest a beta release when ready to test it out. I'd put out the usual clause though about the beta not being a finished project and if you don't understand the nature of beta testing, you shouldn't be running it...

I'm not familiar with the details of what needs to be crunched, but perhaps Android clients could do a Phase 1 analysis and later Phases be regulated to computers. BTW, Octa-cores (they're not true 8 cores ... they are 2 x 4 cores) are becoming increasingly common on Android devices.

While I'm all for the though of Android phones crunching (especially since I currently have two doing that, and will have four total in a few months), if an app were to be developed I'd prefer Linux on ARM to get priority, as there are a wide variety of SBC's (single board computers) out there that are relatively inexpensive (most are in the $40-70 USD price range (Raspberry Pi 3 is $35 USD, ODroid C2 is $42, and the ODroid XU4 is $77 USD - even an ODroid C2 with 32GB of eMMC storage and a dedicated power supply is $92.75 USD).

SBC's also have the benefit of being easily stacked, not to mention most can be powered from a USB charger. Most only draw 4-6W of power too (the ODroid XU4 is 10-12W, but it's also eight cores), and even when stacked can be kept cool with either 120mm fans or an inexpensive desk fan.

There are also Android Mini PCs. They are similar to a PC, powered by an electric socket and with an HDMI cable you can link it to a TV. They often use Amlogic CPUs (quad-core or octa-core ARM 2GHz) with 1, 2 or 3 GB RAM and the cost is 25-100$ depends on the model. I have 3 NEXBOX MXQ-Pro (quad-core 2GHz, 1GB RAM, Android 5.1.1) linked to World Community Grid, Rosetta@Home and theSkynet POGS.

I had totally forgotten about the Android TV boxes. Out of sheer curiosity, do they remain relatively cool, or do they wind up throttling every now and then?

Hmmm, looking at your box on pogs, most tasks are done 3.5-4k seconds faster than my Galaxy S3, and even outpaced my HTC One M8 on the short work units by 3.5k seconds.

Definitely something I'll have to look into. Biggest reason I'm asking all these various questions is I'm contemplating the thought of a small set of SBC's to crunch on (ODroid C2's and XU4's are the main ones that come to mind) but I'd be willing to look into Android tv boxes as well if they're performing reasonably well. ^_^

I use 3 cores on each Android Box and they don't overheat. I use them 24/7 and they have no problem.

700/800 euros for a phone....
With that money you will get a pc with I7. Results? 20 times faster than smartphone.

A lot of people bought a top device because it's beautiful, powerful and so on. If anyone of that people download BOINC app, they could help science progress more than we can imagine.

A decent amount of carriers will offer phones for significantly cheaper if you sign a 1 or 2 year contract, so the initial/upfront cost of the phone is noticeable cheaper. An example would be myself... In April 2015, I got an HTC One M8, which will be added in alongside my two Galaxy S3's and hubby's HTC One M8 when we upgrade our phones in April.

Either way, the device is there, why not make use of it? ^_^

An i7 doesn't fit in your pocket making really hard to lug around to make calls never the problem of needing a socket when you need to make a call. (Okay, granted some of these monster phones don't either...but that's whole other discussion.)

You might have one i7 desktop but 4 phones in a household. Even with 4 phones, you're using maybe a 1/10th the energy of a desktop...

Folks who don't understand computing on Android don't seem to realize that the desktop market is at best, zero growth (sofar as I know, it's still on the negative side). People continue to buy/get new phones so now you don't just have one phone, you have two phones. Now the second phone is doing nothing so you can just plug it in and start crunching for less than the cost to run a fluorescent light bulb with negligible head waste and zero noise.

Android devices are actually rather powerful and comparing them to PCs is more like an apple to orange comparison. They're intended as mobile devices but they gotten more powerful and apps have gotten better that they are replacing PCs for productivity. The lines are getting more blurry each year between an Android device and PCs (can we say tablet like Microsoft Surface and also there's Netbooks).

Yeah, the $500 i7 system is going to run circles around the $500 Android Phone... but then you just spent $500 for a system to run BOINC all day. The other guy got a sweet phone he can talk, send messages, browse the web, play games, check the weather...and when he plugs in, run BOINC. Heck, he could get a $400 phone, get a $50 power pack and run BOINC on the go. New phones have these quick charge features so even if you have to wait to plug in you are running BOINC very soon...

Well, your upfront out-of-pocket is less. Your cost is still the same. It's like buying a car and making a down payment. That Camaro is still 20 grand even if you only put down 5 grand upfront. ;)

Incidentally, ARM devices in general, particularly Pi type devices, are seeing all kinds of people doing new things with them. Folks are even doing clusters with them and they work amazingly well. They're no supercomputers but are proving quite versatile...[/b]

I have 3 TV Boxes Android, 2 tablets and 2 smartphones connected to Denis@Home (the two PCs are not mine), so I have a discreet total computing power. I had a Windows PC but for some reasons now it doesn't work.
However, it's true that with 6-700 €/$ you can buy a PC with an i7, but not everyone want to. Most of families have only one PC but 4-5 smartphones and 1-2 tablets (and the PC has often an Intel Atom/Pentium/Celeron or similar, so not much powerful as an i7 or i5). So, I think, it would be a good idea to let people help the research with their Android devices.
