I want to run a custom kernel build from ci.android.com on an avd. I downloaded the kernel files from here. I start the avd like so - ~/Library/Android/sdk/emulator/emulator -avd Pixel_6_Pro_API_32 -show-kernel -netspeed full -debug init -verbose -writable-system -kernel Image. However the boot fails with the following logs

I know this is because of the loaded kernel modules. I have the kernel modules as well. But I have no idea how to replace them. I pushed them to /vendor/lib/modules. That didn't help. Any ideas? Thanks!
In android, when you open a terminal emulator or connect an adb shell, there is a command service that you can execute which allows you to interact with system services to some degree. For my purposes the functionality is too limited though and I would like to expand it a little.
Unfortunately this executable is not documented.
I have located the source code here: service.cpp
There is also a file called Android.bp in the same directory with the following content:
cc_binary {
name: "service",
srcs: ["service.cpp"],
shared_libs: [
"libcutils",
"libutils",
"libbinder",
],
cflags: [
"-DXP_UNIX",
"-Wall",
"-Werror",
],
}
cc_binary {
name: "vndservice",
proprietary: true,
srcs: ["service.cpp"],
shared_libs: [
"libcutils",
"libutils",
"libbinder",
],
cflags: [
"-DXP_UNIX",
"-DVENDORSERVICES",
"-Wall",
"-Werror",
],
}
Those cflags look like g++ flags to me. I don't really know g++, but after a lot of trial and error I ended up with this:
# Download required source code
git clone https://android.googlesource.com/platform/superproject
cd superproject
git submodule init
git submodule update frameworks/native
git submodule update system/libbase
git submodule update system/core
git submodule update system/logging
# Set required include directories in CPATH
export CPATH="./frameworks/native/include:./system/libbase/include:./system/core/libcutils/include:./system/core/libutils/include:./system/logging/liblog/include:./system/core/libsystem/include:./frameworks/native/libs/binder/include"
# Build
g++ -DXP_UNIX -Wall -Werror -o service ./frameworks/native/cmds/service/service.cpp
Unfortunately I get a massive amount of errors:
https://pastebin.com/fnu7LJLU
My G++ version is:
g++ (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
Any ideas why this is failing?
I want to run custom kernel ( goldfish ) on android-9 (API 28) avd.
So I just downloaded goldfish kernel:
git clone https://android.googlesource.com/kernel/goldfish/ -b android-4.4
make x86_64_ranchu_defconfig
make -j4
then I run emulator :
emulator -avd test -kernel goldfish/arch/x86/boot/bzImage -show-kernel
But there is some error between my kernel and SELinux policy of vendor.
Here the logs:
[ 1.170669] init: init first stage started!
[ 1.172289] init: Using Android DT directory /sys/bus/platform/devices/ANDR0001:00/properties/android/
[ 1.174652] init: First stage mount skipped (missing/incompatible fstab in device tree)
[ 1.176724] init: Skipped setting INIT_AVB_VERSION (not in recovery mode)

[ 1.188030] init: Unable to load SELinux policy
[ 1.189192] init: Reboot start, reason: reboot, rebootTarget: bootloader
Obviously the system go in boot loop.
How can I fix this?
I am using since Android 4.4 the tool make_ext4fs to repack Samsung system images.
make_ext4fs -s -l [size] -a [mount-point] -S [file_contexts] [out_file] [src_folder]
This works fine for sparsed file systems up to Android 5.1.1. I need to repack an Android 6.0.1 system.img of a Samsung device. There aren't any errors, flashing works too but the Wifi device is broken.
This is the logcat output
...

08-30 13:38:35.809 E/wpa_supplicant( 3181): wlan0: Failed to initialize driver interface
...
This the kmsg output
[5.560176] [2: sh: 2269] macloader: Not yet wlan interface loaded
I tried to compare the stock and the repacked images, but they are compressed and not comparable.
Has anything changed with the img format from Android 5.1.1 to Android 6.0.1 or is this a Samsung specific problem? The file_contexts is exracted from the stock boot.img. I think the selinux permissions are fine but I am not sure if the regular permissions are set correrctly. Is there a way to get sure the mac permissions will be preserved?
Update
I've rebuilt make_ext4fs with branch android-6.0.1 according to this link (https://gist.github.com/monyxie/3128671a1f9508b7b9cdcf803e55af1e) which has new options added.
[ -l <len> ] [ -j <journal size> ] [ -b <block_size> ]
[ -g <blocks per group> ] [ -i <inodes> ] [ -I <inode size> ]
[ -L <label> ] [ -f ] [ -a <android mountpoint> ] [ -u ]
[ -S file_contexts ] [ -C fs_config ] [ -T timestamp ]
[ -z | -s ] [ -w ] [ -c ] [ -J ] [ -v ] [ -B <block_list_file> ]
<filename> [[<directory>] <target_out_directory>]
The added option [-C fs_config] let you set the permission of every single file and expects a list of files with its uid / gid / mac-permissions / (optional SELinux context). make_ext4fs throws an error if theres is any file without a config defined.

I'd been using appcelerator CLI for a while and everything is working, until today.
Suddenly when i try to run the following command, an error occur:
appc ti build --platform android -T device
C:\Users\User\.appcelerator\install\5.0.2\package\node_modules\appc-cli-titanium\node_modules\titanium\node_modules\longjohn\dist\longjohn.js:185
throw e;
^
TypeError: Invalid Version: build.0.0
I tried to search and found that there are a lot of post regarding the longjohn.js throwing e as error, but none of them is having the error message Invalid Version: build.0.0
I'm running this from Windows 7, using appcelerator 5.0.2. Targetted android platform
Anyone encountered this issue before? Any suggestion or steps to fix this?
Thank you
UPDATE
Tried to run appc info and got the following error:

I tried appc ti clean but it doesn't help as well.
UPDATE with -l trace
Below is the result i got running appc info -l trace:
