Android Boilerplate

License Apache 2.0 ustwo twitter Platform Android

Description

Android boilerplate project to use as a reference when starting new Android projects. It provides basic architecture, tools and guidelines that we use when developing Android apps.

Modules

This project consists of the following modules:

  • app, Phone & tablet module

Tools

  • Android Studio, Provides the fastest tools for building apps on every type of Android device.
  • Gradle, An open source build automation system.

Testing and CI

Circle

By default this boilerplate comes configured to run on CircleCI. The YML file circle.yml will setup the dependencies, run the tests configured in scripts/ci.sh and export relevant reports and artefacts.

If you have configured the environment variables defined in the "Firebase cloud testing" the tests will be run on the Firebase test lab otherwise your tests will be run on an emulator.

Firebase cloud testing

This boilerplate ships with Firebase cloud testing built in. You simply need to enter the following environment variables to make it work:

  • GCLOUD_SERVICE_ACCOUNT - The service account email address is listed in the Firebase console here: https://console.firebase.google.com/project//settings/serviceaccounts/adminsdk
  • GCLOUD_SERVICE_KEY - This is an export of the contents of the JSON secret file that can be obtained by generating a new private key here: https://console.firebase.google.com/project/<projectId>/settings/serviceaccounts/adminsdk
  • GCLOUD_PROJECT_ID - This is a unique identifier for your Firebase project which can be found in this project's URL: https://console.firebase.google.com/project/<projectId>

The cloud testing setup by default will run your instrumentation tests, take screenshots and save the test report and artefacts.

Signing and secrets

The repository contains two files responsible for secrets and signing; ci-keys.cipher and release.keystore.cipher respectivly. Both files have been encrypted using openssl aes-256-cbc with the key ustwoopensource. These files are intended solely as placeholders to allow you to make release builds and need to be replaced before releasing to the app store.

The current secret management implementation is simple when you have a small number of secrets or files that need encrypting and / or a small team. If you are working on a large project where access to secrets and files should be more carefully managed then we recommend using BlackBox by StackExchange.

Editing secrets

To add, view or edit secrets you first need to decrypt them using openssl:

openssl aes-256-cbc -d -out ci-keys -in ci-keys.cipher -k ustwoopensource

This will creat a file called ci-keys which you can then edit as needed and encrypt again using:

openssl aes-256-cbc -e -in ci-keys -out ci-keys.cipher -k ustwoopensource

The file ci-keys.cipher will then be ready to commit.

The same process can be used with release.keystore.cipher when you need to replace or change the keystore with your own details.

CI setup

For the secrets and keystore to be used by your CI server you will need to export the environment variable CI_SECRETS_KEY with the default key listed above or your own if you've re-encrypted the secrets and keystore yourself. You will also need to ensure that openssl is added as a dependency / installed by default.

Updating gitignore

The gitignore file is generated using GitIgnore.io and using Android and Intellij for the selected technologies. This allows for easy updating when tools are updated or otherwise when required.
