FAQ

Contribution

If you have suggestions for features that you would like to see in future iterations of the SDK, please feel free to open an issue, PR, or discussion with suggestions. This product is fully open source. We welcome any and all feedback.

Support

The PayPal Android SDK is available for Android SDK 23+. See our Client Deprecation policy to plan for updates.

Languages

This SDK is written in Kotlin and supports both Kotlin and Java integrations. See the [Java Demo App](#TODO: link demo when created) and Kotlin Demo App for sample integrations.

Including the SDK

You can support a specific payment method by adding its corresponding feature module as a dependency in your app's build.gradle file. For example, to support both CardPayments and PayPalWebPayments in your app include the following dependencies with the current version:

dependencies {
  implementation 'com.paypal.android:card-payments:<CURRENT-VERSION>'
  implementation 'com.paypal.android:paypal-web-payments:<CURRENT-VERSION>'
}

Snapshot builds of the latest SDK features are published from the main branch weekly. The snapshot builds can be used to test upcoming features before they have been released. To include a snapshot build, first add the repository to the top build.gradle file in your project.

repositories {
    maven {
        url 'https://oss.sonatype.org/content/repositories/snapshots/'
    }
}

Then, add the dependency:

dependencies {
  implementation 'com.paypal.android:card-payments:<CURRENT-VERSION>-SNAPSHOT'
}

Client ID

The PayPal SDK uses a client ID for authentication. This can be found in your PayPal Developer Dashboard.

Documentation

Documentation for the project can be found here.

Release Process

This SDK follows Semantic Versioning. This SDK is published to Maven Central. The release process is automated via GitHub Actions.

Testing

This repository includes unit tests, integration tests, and end-to-end tests.

// TODO: Add sections with commands for running each type of tests

Static Analysis Tools

Detekt

This project uses Detekt for Kotlin code analysis. To run the code analysis:

./gradlew detekt

This will output a list of violations, if any.

Running the gradle task with the -PdetektAutoCorrect parameter, will automatically correct formatting issues:

./gradlew detekt -PdetektAutoCorrect

Detekt rules are configured in detekt/detekt-config.yml.
