Yep, I will start to distribute the Android applications as soon as possible. I'm very busy right now (work issues, papers, projects,...) I will do this after July 10th (please remind me the issue again if it happens that I forgot about... ;)

Hi! When Android is officially supported (for official boinc app and non rooted devices)? thanks!!

At the moment, it seems that the OpenWrt executables are faster than the ones I compiled for Android arm and arm64

ARM IFive Mini 4S RK3288

Doing some tests we noticed that the recently built applications for OpenWrt/Linux should also run on ARM based Android systems. If you have BOINC running on one of the following platforms

arm-android-linux-gnu Android running on ARM armeabi-v7a (32-bit) aarch64-android-linux-gnu Android running on ARM 64-bit arm64-v8a

you could try to configure your BOINC client to use the alt_platform method inside yours cc_config.xml and request to download the proper application

<alt_platform>arm-openwrt-linux-muslgnueabi</alt_platform> (32-bit) <alt_platform>aarch64-openwrt-linux-musl</alt_platform> (64-bit)

After some testing (I need only a few days if there will be enough statistic) I will start to distribute the Androd/ARM applications "the official way"

[edit] we already have vfpv3/vfpv4 applications for ARM 32-bit

Great news!!

I have tried to compile the armv7-a and armv8-a executables for Android, and so far they work well! But I need to complete the tasks to verify that everything is correct and compare the times with the OpenWrt executable and see if it is faster or slower. I published the scripts and makefiles in this thread so anyone can try to compile and optimize it (I'm a developer but I don't have some knowledge of C/C++) http://gene.disi.unitn.it/test/forum_thread.php?id=270&postid=1838#1838

Hi all!

now, I sucessfully compile a 32 bits armv7-a version

I will try to test if it works well on my Ifive mini 4. http://gene.disi.unitn.it/test/show_host_detail.php?hostid=58688

Regarding the 64-bit version, at the moment it works well on my Huawei Nova with boinc in termux http://gene.disi.unitn.it/test/show_host_detail.php?hostid=58688

Hi all!

In this thread, I try to build an Android aarch64 executable and for the moment, it work fine!! http://gene.disi.unitn.it/test/forum_thread.php?id=270&postid=1838#1838

You have to put in the project's director an app_info.xml file with the name of your executable and then restart boinc.
https://boinc.berkeley.edu/wiki/Anonymous_platform
let us know if everything goes fine!

Then, if your procedure worked, you could explain all the passage you've done so that we will be able to compile also for arm32.
Did you compile the app with some extension? (ex. NEON, PIE)

Thanks! I try this and for the moment it works fine!!

It looks that bzip2 library was build with -D_FORTIFY_SOURCE, which is not supported by glibc on Android. You need to rebuild bzip2 with this flag disabled. Here is related question on StackOverflow:
https://stackoverflow.com/questions/22977898/android-4-4-undefined-reference-to-printf-chk

Thanks, I build bzip2 and make with compiled lib and work fine!!

/home/juanro/StudioProjects/boinc-android/src/boinc/samples/pc-boinc/bin/pc: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), statically linked, with debug_info, not stripped

Now, how can I test this binary to view that ir work fine?

Hi!

I'm try to compile an Android binary but I have this error when manually build TN-Grid executable

This is my build script https://bin.disroot.org/?efa76485d88e614e#2uMR2WgifRtYuFyW8vEfHdEU56N5NYDnz87wsk4sQTzd

Good news, so it seems to be working even if the app is not compiled with the android tools and library.
I tried to compile the app in this way (http://gene.disi.unitn.it/test/forum_thread.php?id=270) but it was too difficult for me; I think if someone wants to try it it should be the best way to ensure efficiency and optimization.
By the way, this is a great result.
So let's sum up, which android platforms has been tested by now?
Aarch64?
Arm (32 bit)?
Intel x86?
I do not own a rooted android device, but I think we could ask valterc to set the server to provide a beta android app (with the same binary of OpenWRT) so that we can test it.

I try this on Aarch64 (Snapdragon 625) with termux http://gene.disi.unitn.it/test/show_host_detail.php?hostid=58708 (I use boinc in termux on this device because Boinc app don't work fine in Android 8 or above https://github.com/BOINC/boinc/issues/3495)

And in arm 32 bits Rockchip RK3288 http://gene.disi.unitn.it/test/show_host_detail.php?hostid=58688

If you don't have root on your phone, you can use boinc in termux and configure alrernative platforms https://github.com/truboxl/boinc-termux-client

I also think that asking @Valterc to configure the server to provide a beta application for android with the same OpenWRT binary is a good option at the moment, this way you don't have to configure anything else.[/url]

Posted 12 May 2020 by Juanro49

Hello to all
i was wondering if is already planned an application for android
when will we be able to run tngrid on smartphones?

For the moment, you can try adding alternative platform to boinc (Linux/OpenWrt work fine in Android) http://gene.disi.unitn.it/test/forum_thread.php?id=171&postid=1825#1825

In Boinc Android app, it also works well (but need root to configure alternative platforms)

Posted 11 May 2020 by Juanro49

OK, the "No such file or directory" error is a little bit misleading. Anyway, the recently added applications for Linux/OpenWrt on ARM were statically built (OpenWrt doesn't support libc). You may try to use those using the following alt_platforms:

x32: arm-openwrt-linux-muslgnueabi
x64: aarch64-openwrt-linux-musl

another way to see if it works is the anonymous platform method.

With Linux/OpenWrt works fine, now Gene@Home can run in Android ðŸ‘

Not an Android expert at all... But you could try to run the application form the command line and look at the error messages. Did you check the executable bit of the application? If not try: chmod a+x gene_pcim_v1.10_armv8-a

Permissions are correct. I try to run rosetta linux and work fine, but when I run gene_pcim, it says "No such file or directory"

Edit:

I compared Gene@Home and Rosetta@Home programs and I see these diferences:

Rosetta is compiled with static libs, but Gene is compiled with dynamic libs, I believe thath it is the problem. I think that if you compile Gene@Home arm linux program with static libs, the same executable can work in Android.

Hi you already have some ARM applications, possible to port them to Android?

I'm interested, I tried to run ARM applications on this Android device but it doesn't work. http://gene.disi.unitn.it/test/show_host_detail.php?hostid=58688

I always have the error
<core_client_version>7.16.6</core_client_version>

For example task http://gene.disi.unitn.it/test/result.php?resultid=49791625

The file exists

Other project, arm linux Rosetta@Home tasks works fine in Android termux
