ADK - OTG host mode

Hi There,
I see that the SGS2 supports OTG. Has anyone tried to use the phone with googles ADK? Based on documentation the android dev site, the requirement is that the phone has 2.3.4 loaded. Where the SGS2 supports OTG (host mode), I would be especially interested in whether the phone could work in host mode with the ADK. It appears that that based on this quote from the android dev site that the ADK will not support host mode on 2.3.4 firmware.
USB accessory and host modes are directly supported in Android 3.1 (API level 12) or newer platforms. USB accessory mode is also backported to Android 2.3.4 (API level 10) as an add-on library to support a broader range of devices.

But, Based on the Demo of the SGS2 here USB host mode is clearly supported in the firmware : (I could not post the you tube link, but the video title is "Samsung Galaxy S2 USB OTG demo ".
So I am looking for some clarification on how and what USB capability can be used and developed with in the android SDK using ADK.
Has anyone tried to use the SGS2 with the ADK?

hallo
i tried the OTG, it is perfect , exactly like a video demo.
i bought it from ebay 9.99€
goodluck

So do you think we could have joypad support?

I can confirm that otg works. But I think Samsung added some framework, since all sgs2 firmwares include it. That mostly means not 2.3.4

tank u very nice

As the original question was about the ADK, I can say that my S2 running 2.3.3 has OTG support, but not for the ADK USB accessory mode.
I have also tried ADK on my Galaxy S and various ROMs - two leaked 2.3.4 and CM7.1 all had to have the permissions .XML and JAR fixes to even install an ADK app, but even after doing that it still wouldn't switch into USB accessory mode.
Hoping the UK Xoom 3.1 update includes accessory mode...

Hey i want also doing some test with ADK on my Samsung Galaxy S2 ... Does anyone write to Samsung Support and /or asked some Developer (Android) direct if ADK could work on S2 ? I want to develope with Microcontroller and S2 USB Host .. but without ADK Support i have to rewrite a lot of Source Code to get Controller work like USB Client on S2... and than have to write App...
if you take a look at this http://www.hardkernel.com/renewal_2011/main.php
you could find great Hardware for ADK and these information:
Controlling hardware with the Android smartphone application is another challenge for developers.
We've test our ODROID-A, ODROID-7, Samsung Galaxy-S and Galaxy-S2 Gingerbread 2.3.4 update. But only the Galaxy-S2 doesn't work with ADK open accessory library. We don't know why !!

hope Kernel Patch could help to get ADK working !!!!

would it be possible for someone to build this module for me ...
http://android.serverbox.ch/?p=285
its the usb to serial adapter driver for usb otg,
i dont have the ndk or sdk installed for someone with knowledge its a small job compared to hours for me
i just need the .ko

hi,
I tried getting the ADK accessory mode working on SGS2 (with mbed) for several days/weeks now without success. Must admit i'm a newbie with compiling android kernels. I tried several USB flags in the .config file, but no luck.
The .xml and .jar file in order to install an usb accessory .apk are installed on the device, that was the easy part. Never got into accessory mode, the get protocol version (mbed --> sgs2) always returns an error, so it seems that call does not get through to android (?).

I'm not up to speed with android but I avr program in assembler w avr studio and just took a look at arduino. I ordered the mega adk board and it communicates fine as a serial device over usb. The baud is 9600, 1 stop bit, 8 data bits, no parity, no flow control as is most microcontrollers. Hyperterminal works fine, visual studio .net with system.io.ports works fine for windows applications.
I am curious what android offers for serial comms over usb. There has to be something and I don't. Understand why a kernal has to be compiled vs just an application. A blue tooth shield is available also.

Hey was anyone successful in using the ADK with an SGS2? I found the following "solution" but I'm not sure if this works.
Code:
push a android.hardware.usb.accessory.xml with the content
<?xml version="1.0" encoding="utf-8"?>
<permissions>
<feature name="android.hardware.usb.accessory" />
<library name="com.android.future.usb.accessory"
file="/system/framework/com.android.future.usb.accessory.jar" />
</permissions>
into the device's "/etc/permissions" folder.
That might a be a silly question but is there any way to do this without rooting the phone?

Android 4.4 x86 emulator image

Hello guys. Well, since Android 4.4 x86 image for emulator is not yet available for download from google's or intel's repositories, I built my own build. It's just pure Android 4.4 built from official repositories, no customizations. So, if you don't want to spend 5+ hours building it yourself, you can download it here:
DOWNLOAD

So i have just one question , Can I use this image to boot android on my pc via usb ?

To be honest, I'm not sure. You could be able to use it this way, but it's not made for this purpose. If you would like to use it for this purpose, you should get ISO image or build one yourself.

How do I change this into a ISO file so I can install it to virtualbox?

Guys, this is image for x86 emulator. If you want to have an ISO image, you should compile it yourself.

I have never compiled anything before. Is there some specific way to do it and is it easy? If not then where would I get the x86 emulator to make this image work?

Updated to version 1.1 - now uses branch android-4.4_r1.1
P.S.: I will not answer any questions which could be easily found on google

So I am guessing this is for the android sdk emulator then? If that is the case then it is a little too complicating for me. Isn't sdk emulators mostly for developers and enthusiasts? I am just interested in using an image for putting it on vmware and installing it for use. Well I guess I am off to search google for such a thing and if I find it I guess I will not bother to share it as it would seem everyone knows how to use google to find things that are "simple" to find as aptnutella says. Seriously why would I be asking about such a thing if I didn't already know that it is somewhere in google if I didn't already look. I have been searching everywhere and only found things about the sdk emulator. So I suppose I will keep searching since it is suppose to be simple enough to find.

Updated to version 1.2 - tag android-4.4_r1.2
If you are Arch Linux use, you can find package in AUR.

sorry, slightly offtopic:
if you want to learn how to compile and x86 build go here:
http://www.android-x86.org/getsourcecode
for an 4.3 build, to install via usb, look here:
http://www.android-x86.org/download

do a new iso with link please :good:

ARM KVM (Kernel Virtual Machine) enabled Kernel for Samsung Galaxy S8

Hi. Can someone that compiles kernels for this phone compile one with KVM enabled and make it available to download? It should not be too hard. This would really make these machines appealing if you could spin up VMs on them especially considering how much RAM they have. There aren't many ARM devices this powerful to test with KVM.
This was already done for the Intel x86 based Zenfone 2 and as a result, it can run x86 Windows 10 64-bit edition, Mac OS X, BSD and any Linux distro full speed in a VM.
I'd like to see how well the new ARM Windows 10 performs on these Galaxy phones. It would be a great alternative to running Windows 98 in QEMU slowly. Windows 10 ARM runs Office 2016 and PhotoShop at decent speeds on some of the latest SoCs.
Please reply if you are interested in this feature.

I'm really interested in this too, I have a .iso of Windows 10 ARM ready for testing, but it's useless without KVM. But it's always going to be useless since I have Snapdragon.

Im reeeally interested in that feature too, bump!

I don't even own the Galaxy S8 but I thought I could interest some kernel developers in testing this on a popular device. I'd like to see this magic the Zenfone 2 has offered to some other devices. I recently got a Raspberry Pi 3 and installed OpenSUSE (this has a KVM enabled kernel already) to try to spin up VMs but I haven't had much luck even with debian. I'm not sure if something isn't working right or I'm passing the wrong machine or cpu flags to QEMU. Has anyone tried booting the ARM Windows 10 .ISO using emulation only in QEMU?

How do you know Pi 3 has KVM enabled? Does "KVM" appear in /dev? What does kvm-ok report or virt-manager?
Windows 10 Arm can boot up on some hosts using this method (changing cpu from 57 to 53 might help):
(I cannot post links so Google windows 10 arm qemu rafael)
If anyone can get KVM enabled on modern smart phones running Linux via Linux Deploy or on Pi 3s or on the new HP, ASUS, Lenovo laptops then the above should, presumably, work with this additional flag:
-enable-kvm

This article claims the Pi 3 OpenSUSE image has KVM enabled but the article writer never actually takes a screenshot of an OS booting in it:
https://medium.com/@valdiz777/setti...pensuse-pi3-leap-42-2-xfce-image-22faddf02f48
And yes, I do see /dev/kvm listed when I check. Where do I find the kvm-ok command?

When you install Qemu (comes with KVM modules) and libvirt-bin you can then run a command sudo kvm-ok (Ubuntu/Debian). And this will tell you if KVM is enabled. You could also run this:
qemu-system-aarch64 -M virt -enable-kvm
That will also tell you if it can detect KVM. And the other way that I know is through virt-manager:
sudo apt-get install qemu-kvm libvirt-bin bridge-utils virt-manager
sudo apt-get install qemu-efi
sudo adduser name libvirtd
*restart*
sudo service libvirt-bin start
sudo service virtlogd start
You can then open virt-manager from the GUI (or sudo virt-manager) and it will tell you if KVM is detected or not.
All the other KVM commands I found only tell us about Intel/AMD virtualization - not ARM64.
Incidentally, the version of Qemu on majority of Linux distros is out of date by a couple of years, so I had to update mine after downloading download.qemu.org/qemu-2.12.0-rc2.tar.xz
sudo apt-get install libglib2.0-dev
sudo apt-get install libpixman-1-dev
sudo apt-get install libpixman-1-0
sudo apt-get install libsdl2-dev
sudo apt-get install autoconf
make a new subdirectory named build and cd to that dir
../configure --disable-vnc --enable-sdl --with-sdlabi=2.0
sudo make
sudo make install

Just a personal opinion that you shouldn't undermine other people's effort when you are asking them for something, they are usually more willing to help that way.

Kvm samsung j7 2016
Hello every body!! I can't find kernel for J7 2016 kvm support.

Well it looks like our prayers are answered and our dreams came true. Thanks to the folks at limboemulator.weebly.com, there is now an ARM KVM enabled kernel available for the Snapdragon based Samsung Galaxy S8 and S8+
The latest Limbo PC Emulator even has KVM support even with the ARM builds.

Confirmed working?

Has anyone been able to confirm if this works? Site says it hasn't yet been tested on real hardware. I'm concerned the bootloader may be an issue.

Didn't notice the Snapdragon part of that message, thought it was in reference to the Exynos variant. The Snapdragon variant definitely won't work as it's forced into EL1 on boot at the firmware level so not even a bootloader change could start the kernel in EL2. Very interested if it will work for the Exynos variant though.

I'm testing this now on real Exynos hardware, but there's no /dev/kvm appearing in the android kernel despite the options being ticked. The same thing happened when I compiled a Snapdragon 660 kernel. Perhaps the hypervisor is not accessible under any android device due to the trust/EL2 problem I keep hearing about? Nevertheless, I will test in Linux Deploy to see if I can get a /dev/kvm appear in a container instead, but it's not looking promising...

[MOD] pi TV (AOSP 7.1.2)

I have for a long time wanted a Android TV.
But those are expensive. So I still have my good old flat screen upgraded whit a chromcast 2.
BUT I WANT MORE!!! And i came across a project here on xda (details to come).
A ported Android TV ROM to a pi 3 B.
The problem is that I have a pi 3 B+.
There for I won't work.
Also... I want some extra features like twrp recovery and root.
I have tryed to swap files, flash files, extract files, making searches on google. And nothing.
All I know is that the system is a Sony elf system and even that did not help my just a tiny bit.
So my question is how do I get "under the hood" of this ROM that I want to mod?

pi 3 b+ and pi 3b kernels are different so you must compile a new rom with pi 3 b+ source code and android tv source code

That was kinda the plan.
I am working on building a new ROM at the time but I have no idea of what I am doing.

Can I run AndroidTV on armbian?

Hey folks,
I've an old banana pi m2 berry which is working with armbian.
I just found an Tutorial to install Android TV on an Raspberry via LineAgeOS.
I tried LineAgeOS but it seems to won't work on my Banana Pi.
Any fast solution? Also would be fine to switch the OS of my Device again. Just want this for streaming etc on my TV.

I'm not an expert, but my guess is it's unlikely as Android TV is a modified version of Android, and Android is a long ways away from its original source of Linux. The reason Konstakang used Lineage is likely because it's based on android.

Maybe I find some other android Version which works on my device, thanks for the hint.
