Android Continuous Integration And Deployment

About me

Presentation

  • Why Continuous integration
  • Gradle setup
  • Unit Test
  • Automated test
  • CircleCI
  • Teamcity
  • Deployment with Beta
  • Deployment with Play Store
  • What's next

Why?

  • Automatic build
  • Reduce integration problems
  • Find bugs earlier
  • Code versioning
  • Code analysis
  • Regression testing
  • Monitor build speed and size
  • Anyone can get a fresh build
  • Automatic deployment

Gradle and Flavors

  • Product Flavors
  • Build types

Build types

debug {
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    debuggable true
    applicationIdSuffix ".debug"
    signingConfig signingConfigs.debug
}

Flavor types

dev {
    dimension "api"
    minSdkVersion 24
    versionCode 30000 + android.defaultConfig.versionCode
    versionNameSuffix "-dev"
    dimension "playstore"
    applicationIdSuffix ".dev"
    versionName "${productVersion}.${versionBuild}"
}

Gradle Example

Circle Ci

  • Circle Ci and Github or BitBucket
  • Circle Ci configuration
  • Circle Ci secret storage
version: 2
jobs:
  build:
    working_directory: ~/code
    docker:
      - image: circleci/android:api-27
    environment:
      JVM_OPTS: -Xmx3200m
    steps:
      - checkout
      - restore_cache:
          key: jars-{{ checksum "build.gradle" }}-{{ checksum  "app/build.gradle" }}
      - run:
          name: Download Dependencies
          command: ./gradlew androidDependencies
      - save_cache:
          paths:
            - ~/.gradle
          key: jars-{{ checksum "build.gradle" }}-{{ checksum  "app/build.gradle" }}
      - run:
          name: Run Tests
          command: ./gradlew lintQaRelease testQaRelease
          command: ./gradlew assembleQaRelease
          command: ./gradlew crashlyticsUploadDistributionQaRelease
      - store_artifacts:
          path: app/build/reports
          destination: reports
      - store_test_results:
          path: app/build/test-results

Testing

  • Unit tests
  • Automated tests
  • JaCoCo reports

JaCoCo

build.gradle

apply plugin: "jacoco"

jacoco {
    toolVersion = "0.8.1"
    reportsDir = file("$buildDir/customJacocoReportDir")
}

app/build.gradle

jacocoTestReport {
    reports {
        xml.enabled false
        csv.enabled false
        html.destination file("${buildDir}/jacocoHtml")
    }
}

jacocoTestCoverageVerification {
    violationRules {
        rule {
            limit {
                minimum = 0.5
            }
        }
    }
}

Fabric Beta

}

./gradlew crashlyticsUploadDistributionQaRelease

Fabric Beta

Gradle Fabric plugin

public class CustomApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate(); 
        final Fabric fabric = new Fabric.Builder(this)
                .kits(new Crashlytics())
                .build();
