What’s the point?
BUT!

Use Good Tools
• Stuff You Know
• Eclipse
• Android Studio
• 9-Patch Generator
• Lint Rules
• Don’t use a typewriter to paint

6. 4/8/15

Store code
• Bitbucket
• Cloud-based Git repository
• Team-based Access Control
• Cheap
Git branches

7. 4/8/15

Git branches - git flow
origin/develop
(progress builds)
origin/release/1.0
origin/release/1.1
[origin/]feature/x
Writing Code - Eclipse
• Traditional method of Android development
• Windows, Mac, and Linux support
• Lots of existing support
• XML layout support is okay, better than v1.0
• Old and Busted now
• No further development
• Dev site says to stop using it now!

Writing Code - Android Studio
• New Standard
- reached 1.0 late 2014
• Still in heavy development
• Migration is getting easier
• We’re using it on new
projects, and migrating
old projects too it as time
permits.
Checking Code - Lint
• Command Line tool
• Part of Android Developer Tools
• Lots of support from the Android team
• Our rule: No Warnings!

Custom Lint Rules
• Little Documentation
• Lots of setup (for the first one)
• Few examples (beyond the built in ones)
• android.googlesource.com/platform/sdk/
[build]/lint/libs/lint_checks/src/
• Codify your internal rules
• Tip: 3-line Custom Manifest
Libraries
• Android Support Library
• ViewPager
• DrawerLayout
• ActionBarSherlock ActionBarCompat
• Square Libraries (OkHttp, Picasso, etc.)
• Ion, Volley, etc.
• Home Grown (BRShared)

Analyze
• Charles
• HTTP proxy - analyze requests & responses
• supports HTTPS with some additional effort
Analyze
• Hierarchy Viewer

One Weird Trick!
Add ViewServer to use Hierarchy Viewer on real
devices!
Continuous Integration
• Jenkins
• Every 15 minutes (random per project)
• Check for new code
• Build (using Ant or gradle)
• DO IT!

Jenkins - Multiple Builds
• Debug
• Release
• Staging Servers
• Free
• Paid
• Amazon Appstore
• Google Play
Jenkins - Multiple Builds
• use your build.xml to change config URL or
other parameters at build time.
<property environment="env"/>
<target name="preprocess-build-number" if="env.BUILD_NUMBER">
<echo>Setting build number: ${env.BUILD_NUMBER}</echo>
<replaceregexp
file="res/values/build_config.xml"
match="build_number&quot;&gt;.*?&lt;"
replace="build_number&quot;&gt;${env.BUILD_NUMBER}&lt;"
/>
</target>

Jenkins - Multiple Builds
• use your build.xml to change config URL or
other parameters at build time.
<target name="preprocess-release" if="build.target.release">
<echo>Configuring build_config.xml for a release build</echo>
<replaceregexp
file="res/values/build_config.xml"
match="version_name&quot;&gt;.*?&lt;"
replace="version_name&quot;&gt;@string/version_name_production&lt;"
/>
</target>
Jenkins - Multiple Builds
• Gradle build system makes this easier

Jenkins + Lint
Automated Testing
• We have it, barely
• JUnit + Android extensions
• AndroidTestCase
• monkeyrunner
• Robolectric
