MobileFirst Foundation 8.0 Developer Labs


logo lab session for 8.0

Pre-requisites:

Follow the Setup section to install an Ubuntu image, install the MobileFirst Developer Kit, archetypes and CLI and register at Bluemix.

You can download videos for offline usage from from Dropbox or OneDrive (2.62 - 2.66)

Setup

The recommended way to setup your workstation for these labs is to download the prepared VMware image that has all required software installed and ready to be used. However, if you want to do this on your own you will need to setup the dependencies listed below.

If you will be using ubuntu-based x64 distro, additional packages are required: lib32z1, lib32ncurses5, lib32bz2-1.0, and lib32stdc++6.
Finally, do not forget to set JAVA_HOME, ANDROID_HOME, MAVEN_HOME and M2_HOME and add them to your PATH.

Alternatively to watching labs on YouTube, you can download offline version from Dropbox or OneDrive. The videos are located inside the "labs_en" folder and have "webm" extension. VLC, same as most of media players and browser will be able to play them.
