We earlier heard of this feature in a Google Play Services 6.1 apk teardown by Android Police in June. Now, the team has posted some images of the Co-presence feature setup, which were reportedly found in the apk. The apk is also said to contain XML definitions for the setup process' various layouts.
The purported Google Co-presence images show Android and iOS devices sharing data wirelessly with each other. According to Android Police, the alleged file sharing service could be the cross-platform version of Android Beam. It is said to use location data or Bluetooth for authentication.
Android Police speculates Co-presence may also use the 'whisper' feature first seen in Chromecast for 'ultrasonic authentication'. After authentication, data is said to be transferred via Wi-Fi or Wi-Fi Direct. All this essentially makes Co-presence a contactless feature.
The team has also found the Co-presence API for Chrome in developer channel documents, a mention of the feature in a recently granted Google patent titled 'Co-presence data retrieval system', apart from reviews and issue reports for the Co-presence API for Chrome.
While other details are not known about the feature, the report notes that the Co-presence functionality is expected in "the coming weeks".
Meanwhile, Google is also expected to release the new Gmail app version 5.0 for Android with support for multiple accounts; though a Google-signed apk has already been leaked ahead of the official rollout.With Gmail 5.0 for Android, users will be able to add accounts from other IMAP/POP services, such as Yahoo, Outlook, AOL Mail and more, apart from more than one Gmail account.
