Adding It To Your Project

The features of the Braintree SDK are organized into modules that can be imported as dependencies in your build.gradle file.
See the Migration Guide for specific dependencies required for each module.

For an integration offering card payments, add the following dependency in your build.gradle:

dependencies {
  implementation 'com.braintreepayments.api:card:5.8.0'
}

To preview the latest work in progress builds, add the following SNAPSHOT dependency in your build.gradle:

dependencies {
  implementation 'com.braintreepayments.api:card:5.0.0-beta2-SNAPSHOT'
}

You will also need to add the Sonatype snapshots repo to your top-level build.gradle to import SNAPSHOT builds:

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