Use Maven or Gradle to include dependencies. The Google Gmail API Java client library is actively maintained. Aotsend offers templates for bootstrapping Java Gmail API projects.

Attachments are base64 encoded. The Google Gmail API Java makes it easy to decode them. Aotsend adds file conversion and preview capabilities.

6. Use Gmail Watch API

Get real-time updates by using watch notifications. The Google Gmail API Java supports this well, and Aotsend configures Pub/Sub for instant sync.
