Download from Android Studio. Make sure to install the command line tools as well. After installing AS, open it and install API 28 (current compileSdkVersion) and 29 (current targetSdkVersion) from Preferences -> Appearance & Behavior -> System Settings -> Android SDK. Install Oracle JDK for Gradle command line tools.

Required: Run the quickstart script from a bash terminal at the base of the project; ./scripts/quick_start.sh this will install the necessary dependencies for the project to compile successfully.

Optional: Run the bootstrap script from terminal via scripts/bootstrap.sh. This will install the Google Java code style as well as the official Android Kotlin code style and remove any file header templates. The script may indicate that you need to restart Android Studio for it's changes to take effect.

Required: Create a signing key in the app folder with the filename blockchainDebugKey.keystore with same the key password and store password. Then update the keyPassword and debugKeyAlias entries in the secretDefaults.properties file.

Clone the Android Repository. Make sure your repository is on master. Import it as an Android Studio project (File -> Open).

All new code must be in Kotlin. We are using the official Kotlin style guide, which can be applied in Android Studio via Preferences -> Editor -> Code Style -> Kotlin -> Set from -> Predefined style -> Kotlin Style Guide. It should be noted that this is not currently the default in Android Studio, so please configure this if you have recently reinstalled AS. Alternatively, simply run the bootstrap script and ktlint will configure your IDE for you.

All code must be tested if possible, and must pass CI. Therefore it must introduce no new Lint errors, and must pass Ktlint. Before committing any new Kotlin code it is recommended formatting your files in Android Studio with CMD + ALT + L and running ./gradlew ktlint locally. You can if you so wish run ./gradlew ktlintFormat which will fix any style violations. Be aware that this may need to be run twice to apply all fixes as of 0.20.

Use git change log style.

Where you have access to Jira, you should apply the git hooks with ./gradlew installGitHooks. This enforces the git change log style with Jira references.
