What’s the point?

BUT! Shakespeare Michelangelo

Use Good Tools

•  Stuff You Know

•  Eclipse

•  Android Studio

•  9-Patch Generator

•  Lint Rules

•  Don’t use a typewriter to paint

4/8/15

Store code

•  Bitbucket

•  Cloud-based Git repository

•  Team-based Access Control

•  Cheap

Git branches

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

•  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
