Getting started

Install Android Studio

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 necessarydependencies 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 wellas the official Android Kotlin code style and remove any file header templates. The script may indicate that you needto restart Android Studio for it's changes to take effect.

Building

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 repositoryis on master. Import it as an Android Studio project (File -> Open).

Contributions and Code Style

All new code must be in Kotlin. We are using the official Kotlin style guide, which can be applied in Android Studio viaPreferences -> Editor -> Code Style -> Kotlin -> Set from -> Predefined style -> Kotlin Style Guide. It should benoted that this is not currently the default in Android Studio, so please configure this if you have recentlyreinstalled 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 passKtlint. Before committing any new Kotlin code it is recommended formatting your files in Android Studio withCMD + ALT + L and running ./gradlew ktlint locally. You can if you so wish run ./gradlew ktlintFormat whichwill fix any style violations. Be aware that this may need to be run twice to apply all fixes as of 0.20.

Commit message style

Use git change log style.

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