Project Setup

Setting up a new project

• git clone git@github.com:atomicrobot/Carbon-Android.git
• cd Carbon-Android
• Download Python if needed https://www.python.org/downloads/
• python renamePackage.py com.demo.mobile
• (optional) Rename the project directory from Carbon-Android to something meaningful.
• (optional) Add a git remote to the project (a clean repository has been setup for you).
• (optional) Adding a new activity: ./gradlew app:screen -Ppackage=com.demo.mobile -Pscreen=SignIn

First Run

• When you open up a project for the first time, if you get a "Please specify Android SDK" message when trying to run the app then you need to run a Gradle Sync from Android Studio.

Crashlytics

To register an app to an organization you will need to go to the Crashlytics web dashboard, go to the organization settings, and then get the keys and secrets it displays.

• Update app/src/main/AndroidManifest.xml with the organization api key.

Signing configs

DO NOT use the demo keystore in your apps.

• Note: If you are creating signing keys, consider setting up Google Play App Signing (https://developer.android.com/studio/publish/app-signing.html#google-play-app-signing)
• Run distribution/keys/generateKey.sh release and update app/build.gradle signing configs appropriately.

Quality

Automated Checks

• Unit tests - ./gradlew allChecks

Gradle and plugins

To see what the dependency tree currently looks like:

• ./gradlew app:dependencies

Continuous Integration Setup

These are written in the context of a TeamCity CI setup.

Jacoco Test Report

• ./gradlew clean jacocoTestReport
• To view report go to /build/reports/jacoco/jacocoTestReport/html/index.html

Gradle tasks

This will pull in the current Git SHA and auto incrementing build number as part of the build.

continuousIntegration -Pfingerprint=%build.vcs.number% -PbuildNumber=%build.counter% -PdisablePreDex

for local testing:

./gradlew continuousIntegration -Pfingerprint=DEVTEST -PbuildNumber=222 -PdisablePreDex

Also make sure the CI server is set to use the Gradle wrapper.

Supported Android Versions

The Carbon app will only support those Android versions that Google Security continues to support: https://endoflife.date/android

As of July 15, 2022, the latest Android version that's supported is Android 10. Therefore the minSDK is set to 29
