I don't like to keep you guys waiting, especially the time it takes for the Google Play server's to propagate the new miner, so here's a direct link to the latest free version: http://litecoinforums.org/android/andltc-miner/AndLTC%20Miner.apk

:) --Simran

Looking forward to seeing some results with a C-based miner.

As I said on IRC, I'd be willing to test this on Blackberry 10 Alpha / Blackberry Playbook OS for you.

When this miner comes out,I'd like to test it on an android phone. :)

I'm already compiling Android! This time it was easier than the last time I had tot do this. I might have this C miner out faster than I expected! :)

this is a really good idea, and I could see mobile mining becoming popular especially if it uses the graphics hardware of the device

That would be good as long as I can tell it to be less aggressive in GPU use so I can still navigate around my phone.It's be even better if CPU and GPU can both be used as I'm determined to squeeze every drop of performance from all my devices (Nokia N900/router,etc as they're both run by ARM cpus and can be modified.) and computers (PC/MBP etc).

I just cross compiled pooler's cpuminer for my Kindle Fire. It's dual core! I'm getting 0.7 khash/s per core as opposed to 0.02 khash/s on the old Java miner I had coded awhile back! I'm gonna put this back on the Google PlayStore! I'll post pictures in a couple of minutes! :)

that's pretty awesome, so 1.4 kh/s total?

With NEON SIMD or without?

Yup! That was over adb shell though. It was a bit slower on Terminal Emulator on my tablet. Here's a picture:

https://i.imgur.com/nuMK3.png


What's that? lol

Cool....now I can make about 7 LTC a month mining on my phone!

 ;D ;D ;D

lol probably. Can't wait to test this when I buy my Nexus 7 tab!  ;D

The original code by pooler was an awesome example of using Intel SSE (and/or AVX) to achieve great speedups (about 4 times?) with the help of SIMD (Single Instruction Multiple Data).

Did you attempted to use SIMD on ARM (where it is called NEON)?

All I did was compile libcurl for Android, edit the code to suit Android, recompile it using the Android toolchain I compiled.... lol

The ARM core on Kindle Fire has 128-bit registers in addition to the usual 32-bit registers. This could give a 2-4 times speedup, depending on the exact details of the core used.

There are many ways to use them:

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dht0004a/CHDGDHIC.html
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dht0002a/ch01s04s02.html

You could probably take a look and see how you can do on ARM things comparable to what pooler did on Intel.

Cool. If you want to compile a list of devices and performance for your reference or others, I'd love to test it on my android devices so I'll follow this thread.

Unfortunately not. I have already written a version of the scrypt core that uses NEON (it will be released in the upcoming cpuminer 2.2.3), and the speedup is only about 40% in the best case. There are various technical reasons for this, most importantly the lack of an instruction for bitwise rotation and the fact that current NEON coprocessors can only execute one instruction per cycle, with rare exceptions.
The basic ARM instruction set, on the other hand, is pretty optimal for implementing this kind of hashing functions (thanks to the barrel shifter), but of course it cannot compete with the SIMD implementations of performance-oriented architectures.

An example: a Samsung Galaxy S II (dual-core Cortex-A9 at 1200 MHz) can do about 1.64 khash/s with the current cpuminer code (hand-written ARM assembly), and about 2.3 khash/s with the to-be-released NEON implementation. The speedup is even more modest on Cortex-A8 processors.

Thank you very much for your work and your comment.

I actually don't have an ARM machine to play. I played a bit with a pre-release simulator for a device that incorporates an ARM core. And by "a bit" I mean "floating point only". Because of the pre-release status:

1) instruction timing could be inacurate
2) it could simulate a future version of the ARM core

Thanks again.

Download link please for this miner as I want to try it out.

i 2nd this!

+1 and also a litecoin address to donate back to the op!

I'm mining away at 7.21 h/s right now just seeing if it works.  I like the settings page a lot more than the previous setup.

That's using pooler's JMiner. It was a mistake I made when I coded my first Android LTC Miner. It's too slow and worthless, and was the reason I removed it from the Google Play Store. Now that I compiled the C version CPU Miner, It's a lot faster and more efficient rather than using Android's JVM. And yes, the miner already has a UI :)

Any chance of making it compatible with Android 2.2? I want to burn out my cheap tablet by trying this, but it only has Froyo and can't be updated.

It will be compatible with Android 2.1 and up.

So 0.1 is JMiner-based? I get
18 H/s on an atrix (tegra 2, dual core (1 thread), 1GHz, A9, neutrino rom (android 2.3.7))
35 H/s on an atrix (tegra 2, dual core (2 threads), 1GHz, A9, neutrino rom (android 2.3.7))
16 H/s on a Galaxy S (hummingbird, single core, 1GHz, A8, cyanogenmod 9)

Both at normal priority. So the nexus 7 should get > 80 H/s on Jminer.

12 h/s on HTC Envy  :D

Edit: Wont let me set the miner as a service so cant do it in the background yet.

I just sent it to my Nexus 7, I'll post results in a bit :D

lol i wonder what my iphone would hash at....damn...i guess i gotta wait until its built for ios.

By then I might have mined half a ltc  :P

lol...  :D

In case you guys are wondering, the current LTC miner on Google Play Store isn't mine. Mine is called AndLTC Miner :) which in 3 days will be up. I'm currently on vacation with the family... be back on Thursday or Friday.

this is important stuff, and I guess shows how an arm based system designed to mine litecoin might perform. at 125w, about 166 arm cortex a9 cpus could thus mine only approximately 210khs if I'm doing the math right (cortex cpu ~ 750mW when running neon code fully loaded).

I really don't want to put pressure into you doing this, but are there any updates? Don't forget to tell us when you achieve some more progress... :)

The app is out on Google PlayStore! Read OP!

When I asked you to make it compatible with Android 2.2, it was because I was already guessing it would only be compatible with 2.3 and up, like most Bitcoin and Litecoin apps. I guess it's some problem related to certain libraries not being present on 2.2...

The mistake I made was that compiled the miners using the 2.3 toolchain.

I'm running LTCMiner now on my Galaxy SIII and am getting 61.867 hs/s

My Galaxy SIII Specs
1.5 GHz dual-core Qualcomm Snapdragon S4 Processor
2 GB Ram
32 GB internal Memory
64 GB micro sdxc card

You can get faster speeds if you use my Android Miner... 0_o
Why does everyone think that's my Android miner? Maine's in the OP.

So I just installed yours, I'm getting for thread 0 = 1.09 khash/s and for thread 1 = 1.15 khash/s

Not bad for a phone pulling in roughly 2.25 khash/s


This app is definitely faster, but I did like the fact the other client could save your profile, where as this app requires you input your data everytime.

I'll implement those features tomorrow. I just wanted to release the app to test the minerd binary I cross compiled. Please comment and rate the app highly if you liked it!

I'm pulling 3.1 khash/s testing on my Nexus 7 right now.  Thats pretty sweet for an android based miner.  Well done.

Edit: As soon as i turned the tablet sideways so that the orientation changed, the miner reset.  Thats a bummer.

I'll fix that today, sir. When the orientation changes on an app, it resets, so, yeah, lol.

Is there any way you can compile minerd so that it is run from the command line on the Android system (i.e. compile as a normal Linux binary for ARM)? This would have a few advantages for some specific use cases:
- Possibility to control and monitor the miner over SSH/any other remote shell protocol
- Would run on devices with broken screen (or broken input method)
- Android-version independent (I'm not sure)?
- Better for people who love the command line :)

^^
http://gifsforum.com/images/image/me%20gusta/grand/me_gusta_0341.jpg

lol I thought you guys would fogire it out. lulz. After the app has downloaded the minerd binary, it's in the folder of the my app, which is data/data/com.simran.andltcminer/minerd. I suggest you running it from there, and opening the app occasionally, as my app will update the minerd binary when a new one is uploaded to my server. :)

Would you mind posting here a direct download link for the minerd executable?
a) Not everyone can install from the Play Store
b) Not everyone has an Android device running 2.3 or higher, required just to download minerd (and setting up an emulator is a PITA for such a simple thing)

The minerd binary only supports 2.3+, which is why I set the app to 2.3+.

I guess I'll need to cross-compile minerd myself then...

You're free to do what you want :)

I'm pushing ~3 khash/s testing on my Asus transformer prime Quad core right now

I love the miner for android idea but can someone please compile a version for maemo 5 (OS used on Nokia N900) as I'm unable to compile it due to the fact that I can't code otherwise I would do it,thanks. I curious to see what kind of hashpower my N900 will give me at 1.15GHz (OC'd cpu). :)

Would be good if you could set it to auto mine only when charging to save your battery.  Then every time you charge your phone you get some coins but doesn't slow the device down or drain the battery when your using it after it's been charged.

Just use an app like tasker or smart actions to launch the app once its plugged in and to kill the app when its unplugged.

Running it now on my American(dual core S4 2GB RAM)
Not really expecting it to do a lot, but it is a cool "just cause I can" thing. btw, I got the Pro version to support you for making something so cool.

Getting a json decode error connecting to coinotron, my desktop miners have no issues connecting to it however.

Umm.. not sure what it might be, but tomorrow I'll be releasing an update using the new CPU miner 2.2.3. It will have a regular and NEON minerd binaries.

It'll be interesting to see how the NEON version performs.

pooler & I put up a chart of Android devices we tested using cpuminer 2.2.2, 2.2.3, and 2.2.3 with NEON.

Yea, but looking at a chart and holding the hardware you're testing in your hands is totally different. It's like reading about the horsepower of a Corvette vs. being inside one accelerating. Well, sort of.

Where?

This is so cool.  Cellphone has a broken screen?  Make it hash until it buys you a new phone!

Add my nexus 7 with android 4.1.1 getting 3.2 khash/s.

You'd use more money on recharging your phone than it can produce, haha, but fun nontheless :D

Updated:

https://i.imgur.com/vx9QL.png

Simran, keep up the good spreadsheeting!  I want to know which phones are the most productive, definitely keeping an eye on this.

Tried it, 0.32 KH/s on an S5360, stock ROM (2.3.5)/no OC. I think we're the only 15-year-olds here who aren't scammers(unlike Jake lol).

Starbucks, your buddies car charger while he give you a ride. Mooch man, mooch!

You might want to specify which models of the One X you're using. The US has a different version afaik and definitely has a different version of the Galaxy S3.

It is specified, the US version uses the Cortex-A15 while the Global uses ARM11.. Same goes for the Galaxy S3.

Updated v0.7 08/07/12! Added NEON support, in which the app allows you to use the regular and NEON minerd, thanks to pooler's CPU Miner 2.2.3! It should be more optimized for both versions nonetheless!

Quoted from change log:

I'm still getting http errors, 403 and 401, on two different pools that I can verify the settings work fine with minerd.exe on Windows. Internet connectivity is good on the device as I just updated to the latest version.

My Droid RAZR runs 1.8 kh/s at 1.2 ghz eclipse ROM.

If anyone has already downloaded the new app, please do this:

Settings -> Apps -> AndLTC Miner -> Clear Data

and use the miner again. This solves some issues with the minerd binaries earlier.

4.03 kH/s on my One X using the NEON version! :)

Still only connecting to the default pool, which is closed to registration. So technically it works, but not with any mining pool I've tried to set up.
edit - also the CPU for the One X is a Krait/S4 which isn't quite an A9 or an A15. Wouldn't it make more sense to list the actual CPUs vs an abstract A9/A15 listing?

I'm getting 3.6 k/s now with neon on my nexus 7

Hmmm. Can you try that again? Do this, Settings -> Apps -> AndLTC Miner -> Clear Data, and try to to mine with NEON again.


Will update soon! Thanks :)

Still 3.6 khash/s.

https://i.imgur.com/jO4sL.png

Hey, you didn't include my low-end phone. It's in the last page I think.

My American Galaxy S3(S4 Krait CPU) is getting 2.1kh on regular and around 3.0kh with NEON. This is with AT&T stock 4.0.4 kernel 3.0.8

Are you using it with or without NEON? What processor is it?

I've got two android devices:

My Galaxy Young (S5360) has a Broadcom BCM21553 ARM11 832 MHz processor (ARMv6, single core). Has android stock 2.3.5 ROM. Tested with miner 2.2.3, without NEON (not compatible with NEON). Gives 0.32 kh/s.

My Lenovo A1 tablet, has a single core Cortex A8 1GHz processor, tested with android 2.3.4 (stock ROM), gives 0.86 KH/s with NEON, 0.39 KH/s w/o NEON.

Added:
https://i.imgur.com/GWzca.png

Samsung Xcover. Android 2.3.6 "regular non modded"
Cpu: single core 800mhz marwell mg2
Miner: Default
Average: 0.4kh/s

kHz ?  ::)

Hashes, cycles, they're all the same :-P

Well, the data for all my devices is up now so no new testing I can do. Love the app but there are still some glitches. This is on android 2.3.3 with a tegra 2, I didn't test too much with my other devices:

-about 25% of the time, the drop down menu only has the option of 1 core. Quick fix would be to always have 1-4 as option
-stops mining and resets the number of threads option to "1" about 80% of the time if I rotate the screen
-when the screen turns off, it doesn't prevent idle clocks. This means my Atrix mines at like 200MHz. I tried it on my nexus 7 as well and the console listed speeds that make sense for 4 threads running on a 500MHz single core
-credentials not saved
-console doesn't autoscroll

Samsung Galaxy S3, cyanogen 9, neon, 4 threads, 1.4ghz, 4.77kh/s

I'm still getting a http 403 error connecting to ltc.kattare.com and a 401 error connecting to coinotron. This is with configurations that work flawlessly on several of my PC's that are CPU  mining. I'd try the server that the app defaults to, which I assume you mine with, but they are closed to new registrations. As such the app is useless to me unless I want to mine and have you get the shares.

What can be done to fix these bugs?

I'm honestly not sure.. can I see the config?

Is there a config file?
Here is how it looks "on screen"

That is the default config that it comes with, and it works fine. Below is my setup that returns errors.


I've tried that also with coinotron's server and they both return errors. The phone has internet access via wifi and I can browse the web, SSH into my servers and whatnot, so I know TCP/IP is functioning. I'm guessing perhaps something in the handshake is wrong. Could you try the same settings and see if you get a problem?

I'm getting the same errors, but when I use ltcpool or notroll, it works fine.. weird 0_o

My LG Ally and Mesmerize are so slow they don't even get a share before the next block comes out.

My US SIII barely gets them out in time. I forget, have you posted the code for the minerd with NEON extensions. Maybe some of us hacking on it could eke out a bit more performance. If we can push up to about 10KH/s on a device it might be worth mining when you're out and about and using someone else's electricity(Starbucks, a city bus, a friends house, or a solar panel)

I'm having the several issues that were reported already: not saving credentials, resetting when the screen is rotated.

Also, on the free version the ad covers up part of the console, and when held sideways, I can't even see any of the console.

Is there any real reason for requiring android 2.3? I've got an old phone that I wanted to test but the stock kernel is stuck on 2.1

Simran's project is a GUI for cpuminer, not a separate fork of it.
The NEON code was already available when cpuminer 2.2.3 came out on August 5. Release notes here (https://bitcointalk.org/index.php?topic=55038.msg1079996#msg1079996).


The commit that adds NEON support is 3419ca2 (https://github.com/pooler/cpuminer/commit/3419ca26076dbac16752c721a680c3ec950482bd).

So I can use a terminal, either via an app or adb and run minerd manually as well? What folder is the binary stored in? I want to see if I can fix my problem that way. Maybe Simran can then figure out the issue and add a patch in.

It's in "/data/data/com.simran.andltcminer/". There's 2 minerd binaries, "minerd-Regular" and "minerd-NEON".

I'm not sure what the issue was. I was running stock AT&T 4.0.4 and was getting those errors. Today I installed CM10(Android 4.1.1) and am having no issues connecting with  my S3.

I'm getting 2.1 khash/s on my VZW Galaxy Nexus w/ CM10 4.1.1 @ 1.2ghz

3.4 khash/s @ 1.8ghz but its not very stable at this speed for me.

Tried it and it seems to be working on my HTC Desire HD with 1 GHz Qualcomm 8255 Snapdragon (http://en.wikipedia.org/wiki/HTC_Desire_HD (http://en.wikipedia.org/wiki/HTC_Desire_HD)). With NEON it gives 0,96-1,05 khash/s, without it about 0,7. I have the same problem like others, when I change the orientation of the phone, it stops.

 :D

Wow! Where did you get that solar panel? I would love to have something like that in my boat.

I got it off ebay.

I feel sorry for that phone once the sun comes out and beams right on it.

Any plans to update this to the newer APIs 16 and up for Android 4.1 and soon 4.2? I realize me buying the app isn't going to make you rich, but I think it's an awesome idea. More for the fact of "it can be done" and that it does expand what is possible.

I'd love to see this ported to the x86 android market as well as Windows RT!

It's using the API's for Android 4.1, and when I get more time due to school, I will update the app. I've already gotten a small list I want to add:

1. Fix when the device to turn(Keep mining)
2. Move API up.
3. Autoscroll in text box(Console)


x86 Android Market? Windows RT? I don't get it?

For instance, there are the old first gen google TV's that run on an Intel(not ARM cpu). The upcoming Medfield phones are also Intel based. I was under the assumption you could select multiple think APKs per architecture to compile for when you made an app. There was actually news that google just merged support for this into the Play store.

Windows RT I would think would be a logical place to port the code. The CPU in them is ARM, typically the same as in tablets and phones. It should be an easy port. Windows RT is "Windows 8" but for ARM SoCs.

Didn't know my app was on the play store for GoogleTV. Once I get home, I'll try my GoogleTV and see. Since it is Intel, wouldn't the precompiled Intel binaries work? As for Windows RT, they current ARM binaries don't work? If not, I'll see wut2do. Gonna talk with pooler again.

No, the device isn't on the Google TV. You'd need to set it up to compile for a different CPU type. It appears Google just recently enabled this. I imagine you'd need to update your Android SDK on you machine and maybe the client SDK's not sure. Here is the URL

1.98Khash/s on Galaxy S2 Epic 4G Touch (Sprint network)  ;D

1.14Khash/s on a overclocked HTC Desire.  I need to buy a quad-core phone to mine on now lol

PS

I've found you mine more liquidcoins. Given that this is really just to stroke our egos and make us feel like we're working, the numerically larger LQC mined "feels" better. I'm charging on solar anyway, so it isn't costing me.

The app doesn't compile the binaries on the device. I cross compiled the cpu miner for ARM, so the app simply downloads the precompiled binaries. What I suggested was that you should try the current Intel precompiled binaries on a GoogleTV device, as they are Intel CPU's. There's no need to update the API's for the app either, but I'll go ahead and do so like I said.

I haven't had any luck running binaries on my Google TV. I've got the Sony bluray player. I have tried a couple of precompiled(static) busybox's and I believe Sony set the filesystem masks such that I can't execute any files.

I have tried this (With the paid app) on my Nexus 7, and have not got it to work with 3 of the usually named LTC pool mining sites. I have not tried it on my HTC Rezound yet.

I get an error no matter the site i use, i have double checked every informational site and i seem to be entering everything correctly.

My Nexus 7 is Rooted if that means anything to the situation.

I'm in the process of moving the server the miner files were on. That's the issue that my shared hosting is up and down, nothing with your devices.

Will it work very soon, like do you have an ETA (I hate asking developer that, I find it disrespectful.) If it is a while are you offering refund on the paid version?

Should be working since I moved everything to my VPS and changed the nameservers of my the domain it was on.

Any plans to update this app anytime soon to fix the GUI issues?

I'm not sure how to fix it as to just keeping it one orientation. :\

In that case, would you mind changing the #of threads dropdown to a fixed number we can change, without trying to detect the cores? On my Atrix, SGS and Nexus 7, more than 1 thread is not an option in the menu until I have changed the orientation to horizontal.
Have you been able to figure out why the miner stops mining and all the fields go back to default when the orientation changes?
If you have abandoned development on this project, have you considered making it open source?

Will do on the next update soon, just been caught up with other projects! :)

I tried it on my HTC Rezound, Nexus 7, and Droid DNA...cant get it to work.

Is this thread still going? I really appreciate the ability to use my phone to mine  ;D. Being a complete noob to mining I have a few questions.

 I am trying to use this ap on my Driod Razr Maxx HD. (Specs http://www.gsmarena.com/motorola_droid_razr_maxx_hd-4972.php (http://Specs http://www.gsmarena.com/motorola_droid_razr_maxx_hd-4972.php)).  How do I tell the total khash/s?  I running two threads: thread 0 = 0.53 khash/s, thread 1 = 0.63 khash/s.

I don't think it has shared anything with my mining pool (notroll) either. Is it too slow?  
Also the phone can play HD videos would there be a way to tap into the graphics card and mine using GUI or something?


EDIT: Just checked my stats at notroll again, and it has submitted 3 shares, and is doing 3.5 khash/s. This is using NEON with 2 threads.

Thanks in advance.

Hey, could you post the source code on GitHub? I think it would allow for others to help out with the issues as well as help optimize for their platform.  There is also the GPL issue (you would only have to post the part of the code that you use from pooler if you are worried about someone else ripping you off - although I think you have made a name for yourself).  Also I'm unsure if pooler could wave the GPL rights, even though he's done a ton of work himself, others contributed as well and I think you'd have to go back to Jeff to get permission =p.  But it shouldn't be about licenses, it would just allow improvements to be made by other Android developers.

This app seems to not support stratum+tcp:// pool addresses. More and more pools are ditching getwork in favor of stratum, so this app needs to get with the times or suffer the fate of 1 star reviews.
