What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Using Go `cgo`

cgo has a lot of trap.
but Not "C" pkg also directory in $GOROOT/src. IDE's(vim) Goto command not works.

So, Here collect materials.

First step: Install Android SDK

yaourt -S android-sdk android-sdk-platform-tools android-sdk-build-tools
Note: Maybe you'll have problems with the lasta package: ncurses5-compat-libs. In order to avoid this problem you have to use this command: gpg --recv-keys F7E48EDB. You can find clarification here.
yaourt -S genymotion
Note: You'll need install virtual-box and his modules, yaourt will make for you but you need choos between ArchLinux host modules or DKMS host modules.
Enter in super user mode with su - and then do echo -e "vboxdrv\nvboxnetflt\nvboxnetadp\nvboxpci" > /etc/modules-load.d/virtualbox.conf
Note: You need do this with super user because need super user permissions and with sudo, for us at least, doesn't work.
sudo modprobe vboxdrv vboxnetadp vboxnetflt
Activate for current session.
sudo chmod -R 777 /opt/android-sdk
