Dropbox and Yahoo! announced that they will be integrating their services to offer seamless file attachments in the Yahoo! Mail Android app. This is to challenge what Google offers with Gmail and Google Drive. Users that authenticate with their Dropbox account from within the Yahoo! Mail app will now be able to select either local or Dropbox files from the “attach” menu, and simply send out files that are stored in the cloud.

The update should appear soon in the Google Play store for the Yahoo Mail app.
