Testing Android 11 OS Build - Emulator Crashing - Android Software/Hacking General [Developers Only]

I have built stock 64-bit Android 11 with Pixel5a hardware drivers. The build declared no significant problems. The issue now is how do I test it. I have tried to run the Android 64-bit phone emulator for i86 chips using lunch and I get:
emulator: WARNING: Not all modern X86 virtualization features supported, which introduces problems with slowdown when running Android on multicore vCPUs. Setting AVD to run with 1 vCPU core only.
Segmentation fault (core dumped)
I am using a build machine with an Asus P6T motherboard, 24 Gbytes memory, and an Intel I7 920 CPU.
Any suggestions as to where to look to fix this would be appreciated.

[Q] Android port to Satio

Firstly, apologies but as a new member I cannot post to the developers area.
I want to know if anyone has put any effort into a port of android to satio? I believe the first part shouldn't be too challenging as Android has already been compiled to the OMAP3430 SoC. I am familiar with setting up an arm cross-compiling toolchain and have worked with the arm9260 chipset in this regard (including writing kernel drivers).
As I haven't developed for a phone before, I'm not sure how easy it is to access the bootloader and download a new kernel.
Beyond that I'm in new territory regards the neceeasry drivers and accessibility to the information to develop the kernel code required
I look forward to your comments.
Regards, Steve

[Q] Fedora-17-beta-armhfp-xfce on Xoom?

Fedora has released Fedora-17-beta-armhfp-xfce, a system image compatible with Tegra devices. A kernel image is not included. So, my first question is: Are there any kernels being tweaked and developed by xda members that are compatible with the the Fedora release? If not, it appears from the many posts in the forums asking about Linux on arm tablets that there is a void to be filled.
I for one want to be free of big brother "Google" and regain not only full control over my device, but my privacy too. Richard WM Jones describes how he installed Fedora on a Trim Slice with Tegra processors. rwmj.wordpress.com/2012/02/29/trim-slice-pt-3/ Can't this be done with the Xoom using a hacked kernel being tweaked/developed by an xda member? Is a kernel already available with drivers that make the Xoom's hardware fully functional in a Fedora installation?
Can the "U boot" ROM supplied with the Slice be ported to the Xoom? We need help from knowlegeable, experienced developers here at xda to make the possibilities a reality.
Thanks,
Armido

Fedora does not replace android but can be installed.

May 26, 2013: The short answer is apparently no. Not even Ubuntu Touch will replace the android core. However a growing number of linux distributions can be installed using installers like 'Linux Installer' downloadable for free from GooglePlay. This includes Fedora. What is the point of having Ubuntu Touch on tablets if the rich, robust and numerous existing linux programs will not run on Ubuntu Touch?

Newbie programmer asking for a list of devics that have the Android Intel x86 Chipset

I am a beginner Android developer and a newbie to this forum so apologize if I posted this in the wrong forum or this has already been answered!
I am doing a research project on Android Intel x86, I was wondering if anyone knows where to get a list of mobile and tablet devices that have the Android Intel x86 chipset?
Thanks in advance

I do not know of a list anywhere, but you can usually bet that if it is an intel device, it is probably x86. You could start by searching for android intel devices.

Force use ip neigh show on android 11 development

Hello everyone !!
I am trying to get list of connected custom devices to my mobile hotspot on an Android 11 phone.... if I use Termux app I can exec "ip neigh show" and obtain devices list but if I do the same programmatically on my app implemented on Android Studio with Process proc = runtime.exec("ip neigh show"); that doesn't work... is there a way to force execute that process via code? Maybe does that depend on setting force minSdkVersion , targetSdkVersion, compileSdkVersion on Gradle config and AndroidManifest.xml to force backward compatibility even if being on Android 11 phone because that permission maybe is Sdk version related? Or is there an alternative for android 11+ to obtain hotspot's connected custom devices programmatically?
Thanks to all in advance!!! Cheers! npuleio

How to install LineageOS on Limbo ARM emulator?

Hello, how to install LineageOS on Limbo ARM emulator?
I want to do some development work that needs rooted Android system compiled with ARM instruction sets. I have used several Android emulators on Android, but they all have various problems.
I don't want to use Android x86, because it is incompatible with ARM apps and will cause great performance loss.
I do not intend to root my smartphone, because I do not want to expose my smartphone to danger.
try finding a iso for it!
or tutorial for it?
I have searched for it in the web, but there are no ISOs or tutorials for it.
there is lineage os 14.1 x86 builds. or other android versions too! but i dont think they will work on the arm version. i used to use boschs back in the day with my old tab. i havent used emulators since. you could give it a try. just search android x86 on google. i remember there used to be versions of limbo that emulated x86. anywho hope it works
Running a custom Android OS ( here: Lineage OS ) in an Android based emulator like Limbo requires you need to install an Android version with a KVM enabled Kernel.

it maybe possible since android x86 iso's are availble. including lineage os 14.1
Perhaps the LineageOS development team should make installers for Limbo ARM or other ARM emulators.

i dont know. maybe you could try gsi's? using dsu sideloader? go search it up. the sucess rate on locked bootloaders and non rooted devices is very low but its worth a try.
IF YOU VOID YOUR WARRANTY SOMEHOW dont blame me please... alr got alot going on in my life rn
Thank you for your help. It seems that I have to abandon this idea currently.
By the way, Limbo x86 emulator runs as slow as a PC in 1995 on my device. (I'm using MediaTek Dimensity 810 @ 2.4 GHz with 8GB RAM.)

yeah its super slow. better abandon this. and lineage os 14.1 native bridge never worked for me. meaning that some apps wont work at all e.g. some games and will crash.
According to my research, the performance of a virtual machine in Limbo x86 emulator is equivalent to about 4.12% of the physical ARM smartphone's performance.
I said that:"I have used several Android emulators on Android.", these emulators don't have performance problems on my smartphone. These emulators are:
VMOS / VMOS Pro - You need to pay to become a member to use rooted virtual machines. Its theory is similar to Anbox.(Off Topic: Perhaps the Anbox development team can make an installer for Android.)
VPhoneGAGA - You need to pay to become a member or watch advertisements to use rooted virtual machines. Its virtual machines contains advertisements unless you are a member. The theory of this software is to rewrite linux's C functions.
F1 VM / X8 Sandbox- You need to pay to become a member to use rooted virtual machines.
V8 Box - It's free and ad-free. It provides rooted virtual machines for free. But at present, this software only supports Android 5.1. This software is only available in Chinese.
