#Introduction If you're a php developer on ubuntu, there comes the time where you have to install/reinstall your system. I did it already a few times and i decided to write down the steps for a typical web developer stack with php. This is for a developer machine and not for a live environment!

I hope it helps you too!

fyi @mheiniger and me started with an installer here: https://github.com/mheiniger/webdev-setup

Genymotion is a Virtual Android Environment built on x86 and Virtualbox. It's not an ARM emulator so it's performance is way better than the Android SDK Emulator. However in their latest update they've removed both ARM Translation and Google Play Apps. (This is what causes the "INSTALL_FAILED_CPU_ABI_INCOMPATIBLE" errors) Many Devs and Users still find these features very useful for various reasons and their removal has forced people to look for alternatives to Genymotion.

This guide is for getting back both ARM Translation and Google Play apps in your Genymotion VM.

UPDATE-v1.1: I've gotten more up-to-date builds of libhoudini and have updated the ZIP. This fixes a lot of app crashes and hangs. Just flash the new one and it should work.
Download the following ZIPs:
ARM Translation Installer v1.1 - http://goo.gl/JBQmPa(Mirrors) ON DROPBOX
Download the correct GApps for your Android version:
Google Apps for Android 4.3 - http://goo.im/gapps/gapps-jb-20130813-signed.zip ON DROPBOX
Google Apps for Android 4.2
