Android Development At Scale That Your SysOps Will Love (AnDevCon Santa Clara Dec. 2 2015)

Large software teams? Millions of users? There is no time for "works on my machine." Let's dive into professional build tools like Vagrant, Docker and Jenkins to attack the pitfalls of shipping Android at scale. Your Operations team will thank you. This class will cover real-world examples and show how the largest apps in the Play Store are built, tested and performance-enhanced.

23. Vagrant • Vagrant provides easy to configure, reproducible, and portable work environments built on top of industry-standard technology and controlled by a single consistent workflow to help maximize the productivity and flexibility of you and your team. • To achieve its magic, Vagrant stands on the shoulders of giants. Machines are provisioned on top of VirtualBox, VMware, AWS, or any other provider. Then, industry-standard provisioning tools such as shell scripts, Chef, or Puppet, can be used to automatically install and configure software on the machine.
24. Vagrant • Recipe is called “Vagrantfile” • You can create reproducible and portable environments, excellent for experimentation AND sharing • A single file defines the machine, can be checked into source control • No more “works on my machine”
25. Vagrant • Learn more at vagrantup.com • $ vagrant up • $ vagrant ssh • $ vagrant halt • $vagrant destroy

28. Docker • Initially written in Go by Solomon Hykes • Docker automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization on Linux. • Docker uses resource isolation features of the Linux kernel such as groups and kernel namespaces to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines
29. Docker • Build, Ship, Run • Make your SysAdmin or Ops guy happy • Great for apps with distributed resources

32. Docker • Won’t run on Mac out of the box, OS X doesn’t support system-level virtualization even though BSD has jails • boot2docker or run inside vagrant Ubuntu • Google notes • Learn more - docker.com

34. Jenkins • Java based, forked from Hudson after Oracle drama • Continuous Integration software • Monitors execution of builds • Makes it easy for anyone to make a build, turn source into product
35. @5280mark #AnDevCon
36. Jenkins • Pro Tip: Install in a container, avoid service sludge • Pro Tip: Name your jobs consistently • Pro Tip: Clean your workspace! • Pro Tip: Have a process for broken builds
37. Jenkins • Jenkins builds can be triggered by a commit or many other triggers (cron, etc) • Consistently and repeatedly build your project the same way • Started by Kohsuke Kawaguchi
38. Jenkins • Plugin Support • Publish to Play Store (Google Publish) • Git • Gradle • Credentials Binding (secrets) • Findbugs • Android emulator • Android Lint • Checkstyle • DRY • PMD - like findbugs, analyzes byte code for potential glitches • Warnings - Displays compiler warnings • Static Code Analysis - Compiles many of above and puts into a graph
39. Jenkins • Slaves - can be docker instances • Master Slave model allows many builds from one master • Slaves can be local, remote, containers etc
