Instlling React-Native Android Environment in ArchLinux

First step: Install Android SDK

  1. 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.
  2. 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.
  3. 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.
  4. sudo modprobe vboxdrv vboxnetadp vboxnetflt
    Activate for current session.
  5. sudo chmod -R 777 /opt/android-sdk
You can’t perform that action at this time.
