Mobile Development
Tools and Practices

Our Motivation
• Observations
• eXo Mobile division had many difﬁculties to
stabilize applications (build failures,
dependencies to the development
environment ...),
• Functional and technical feedbacks were very
limited because the deployment/update
process was complex for testers / early
adopters.


Our Motivation
• Prescription
• Continuous build and deployment of mobile
applications (iOS, Android)
• to speedup the feedback loop
• to increase the number of testers / early
adopters
• to increase the quality and the stability of
these applications.


Our Motivation

• CI wasn't easy to setup the ﬁrst time,
especially for iOS. The experience is worth
being shared.

Environment overview

The Development
Environment for iOS


iOS Development
Toolbox

• Xcode
• http://developer.apple.com/xcode/


Setup a Development
Environment for iOS
• Apple documentation
• http://goo.gl/Ge13t
• The most important part is to register your
Apple developer account and to correctly
set your code signing identity

Environment for
iOS
The developer can spend the
major part of the day in Xcode
and the emulator as long as the
code is regularly committed in
the SCM


The Development
Environment for
Android


Android Development
Toolbox
• Java JDK
• http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Android SDK
• http://developer.android.com/sdk
• Eclipse 3.7 IDE for Java Developers
• http://eclipse.org
• Apache Maven
• http://maven.apache.org/


Setup a Development
Environment for Android
• Installation
• Java JDK
• Android SDK
• Don’t forget to set the ANDROID_HOME environment variable
• Maven 3.0.3 min
• Required by the 3.0 version of the android plugin
• Eclipse
• Use Java Developers edition with its Maven integration (m2e)
• Don’t forget to conﬁgure your Maven and ADT paths in eclipse
settings.

ADK

Maven POM for an
Android Project
• Packaging = apk
• Uses the plugin
com.jayway.maven.plugins.android.generatio
n2:android-maven-plugin
• version 3.0.0 min
• manifest-update goal bound to the phase
process-resources


Setup a Development
Environment for Android
• Just import your Maven/APK project in eclipse with m2e.
• M2e and its market place will automatically install and
conﬁgure the Android extension in eclipse
• You’ll be able to manage your project dependencies with
Apache Maven
• You don’t have to explicitly use Maven in your development
process. M2e does the necessary to hide it.
• Manage your Android project with Apache Maven

Continuous Integration
Environment


Toolbox
• Jenkins
• http://jenkins-ci.org/
• Java JDK
• http://www.oracle.com/technetwork/java/javase/downloads/index.html

• Android SDK
• http://developer.android.com/sdk
• Apache Maven
• http://maven.apache.org/
• Xcode
• http://developer.apple.com/xcode/


for iOS
• Jenkins with the Xcode plugin
• https://wiki.jenkins-ci.org/display/
JENKINS/Xcode+Plugin
• Requires a MacOS platform to build (using
a Jenkins agent if necessary)


for iOS
• Configure the environment where build will be run
as a development environment (Xcode +
certificates)
• Connect your Jenkins Server to an iOS agent :
• Use a dedicated user account on the agent host,
• Allow Remote Login (Sharing preferences) on the
agent to connect to it using SSH,
• Configure an SSH key on the Server that you will
authorize on the agent (~/.ssh/authorized_keys)


Dedicated account for Jenkins agent
on Macos X host

Activate Remote Login (aka SSH)

for iOS
• Create a freestyle job in
jenkins with an Xcode
Build Step

• Ask to build the IPA

• Conﬁgure it to unlock
the login keychain

• Use build variables to
generate a unique
technical version


for iOS
• “User interaction
is not allowed”
error returned while
signing your binary ?

• Launch one time
manually the build on
the agent to validate
permanently the
access to the keychain
for the process
“codesign”


for Android
• Install an Android SDK on all agents where the
android job can be launched
• Configure in Jenkins
• JDK 1.6+
• Apache Maven 3.0.3+
• ANDROID_HOME environment variable or define
the property android.sdk.path in a profile
activated from maven settings.xml
configuration file.


for Android
• Create a Maven Job
• Use the property
“android.manifest.versionCode”
to inject a unique version number in the
application Manifest


Continuous
Deployment
Environment


Continuous
Deployment Toolbox
• Jenkins
• http://jenkins-ci.org/
• Appaloosa Store
• http://appaloosa-store.com


Private Store
• Appaloosa allow you to manage a private
store for Android or iOS devices
• Even if our applications are deployed in
public app-stores after the release we
rely on a private app-store to easily
deploy tests versions to our QA or our
early adopters.


Continuous Deployment
with Appaloosa
• Install the appaloosa plugin in Jenkins
• https://wiki.jenkins-ci.org/display/JENKINS/Appaloosa
+Plugin
• Get the organization token in the administration panel of your
appaloosa store
• Create a private store for each system : One for iOS and one
for Android
• Conﬁgure in each job a post build task to deploy binaries
• **/*.ipa for the iOS build
• **/target/*(-aligned).apk for the android build


Continuous Deployment
with Appaloosa
• Check your emails and
install the Appaloosa
Store App or open the
website on your mobile.

• Both of them will warn
you about the availability
of a new version of your
application.

• Just install/update it


FULL SCENARIO


iOS development

Jenkins plugins

Xcode build conﬁguration in Jenkins
for iOS jobs

Post-build conﬁguration for iOS Jobs
in Jenkins

Let’s launch the iOS jobbuild

We receive a
notiﬁcation
from Appaloosa
(using the private store
application)


Notiﬁcation sticker
on our Appaloosa
store app


In the application
detail screen we
can see the update


Application
