Android: automate deployment to Play Store with Fastlane

Android beta release

• Checkout release-android
• Merge master into release-android
• Run ./tools/shrinkwrap.sh
  release_number = "#{versionName}-#{versionCode}", ex 1.0.0-x
• Commit "Release Android #{release_number}"
• Add tag "android-#{release_number}"
• Push release-android + tags
• Launch Jenkins job on the release-android branch
• Set build description: Release 1.0.0-x
• Download app-release.apk, upload it to the Play Store in https://play.google.com/apps/publish: APK > Beta Testing, once uploaded publish it to Beta
• On master, increment versionCode in android/app/build.gradle and android/src/main/AndroidManifest.xml
• Commit "Post Release Android #{release_number}" and push
• When the Play Store sends a notification about the beta app gone live in the Play Store:

  the Nuxeo Mobile app might be automatically updated, otherwise you can update it through the Play Store
