I got Android emulator crashed("core dumped") issue while launch "selenoid/android:8.0" on linux CentOS7

julialiuliu commented 5 years ago

My Linux server OS : Linux Server: CentOS Linux 7 (core) Kernel: Linux 3.10.0-957.12.2.el7.x86_64
browser.json is Under "/selenoid" folder and the full content is { "android": { "default": "8.1", "versions": { "8.1": { "image": "selenoid/android:8.1", "port": "4444", "path": "/wd/hub", "tmpfs": { "/tmp": "size=128m" } } } } }
I run "docker run -d --name android -e ENABLE_VNC=true -e SKIN=WXGA800 --privileged -p 5900:5900 -p 8888:4444 selenoid/android:8.1" under "/selenoid" folder. And I got core dumped while starting "Starting QEMU main loop". It seems the emulator is crashed in the docker container.

The full log is like below: [root@104028cg53505qp selenoid]# docker run -d --name android -e ENABLE_VNC=true -e SKIN=WXGA800 --privileged -p 5900:5900 -p 8888:4444 selenoid/android:8.1 45e9b87419e0c027fc0bd437e5befb5cf5cdd71d9ce26a4e862430d7d5cba453 [root@104028cg53505qp selenoid]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 45e9b87419e0 selenoid/android:8.1 "/entrypoint.sh" 9 seconds ago Up 7 seconds 0.0.0.0:5900->5900/tcp, 0.0.0.0:8888->4444/tcp android [root@104028cg53505qp selenoid]# docker logs android

If I use "cm" to launch "android:8.1" and selenoid-ui, then I would not see "android" on "http://localhost:8080/#/".

./cm selenoid start --browsers "android:8.1" or ./cm selenoid start configure --browsers "firefox;android" --last-versions 2 --tmpfs 128 --vnc --force ./cm selenoid-ui start

julialiuliu commented 5 years ago

I doubt it is because the linux kernel is too old, because I saw the emulator log printed: emulator: Auto-detect: Kernel does not support YAFFS2 partitions.

@vania-pooh , do you have any idea? Also I have question regarding how to debug if I use cm to launch the selenoid:andriod?

vania-pooh commented 5 years ago

@julialiuliu

Sorry for the delay.

1) Correct CM command is:

$ ./cm selenoid start --browsers "firefox;android:8.1" --force # --force will overwrite config file

Using this command you should see Android. On your screenshot you have a red SSE indicator (both SSE and Selenoid should be green) and this seems to be a connection issue between Selenoid and Selenoid UI.

2) Regarding to emulator - you should have a core dump file in working directory (a file named /coreXXXXX). Having this file we could try to print a backtrace of the segfault with gdb or similar tool. However this seems to be rather complicated. Could you try one of the following:

Turn SELinux on CentOS (it could be blocking something required by Android emulator)
Use a modern Linux kernel (e.g. 4.x).

We are usually testing our images under Ubuntu 16.04 or 18.04. I think this is something related to CentOS security.

julialiuliu commented 5 years ago

Thank you @vania-pooh for the reply.

I updated the kernel to 5.1.8 on my CentOS7.
I checked the SELinux is ON, on the CentOS7.

I build android docker image on OS: CentOS 7, Kernel version: 5.1.8-1.el7.elrepo.x86_64 Launch the container and log into it, to run Android emulator manually via command "/opt/android-sdk-linux/emulator/emulator -no-boot-anim -no-audio -no-jni -avd android8.1-1 -sdcard /sdcard.img -skin WXGA800 -skindir /opt/android-sdk-linux/platforms/android-27/skins/ -verbose -gpu swiftshader_indirect -qemu -enable-kvm" , get error like this: "QtLogger.cpp:66: Fatal: This application failed to start because no Qt platform plugin could be initialized."

To manually debug the emulator and Qt run the following exports:

export QT_DEBUG_PLUGINS=1
export ANDROID_EMULATOR_DEBUG=1

Also I was able to get all the Qt errors solved in CentOS by installing qt5-qtbase-devel

yum install -y qt5-qtbase-devel

aerokube / images

I got Android emulator crashed("core dumped") issue while launch "selenoid/android:8.0" on linux CentOS7 #142
