A release date has been revealed for Google Play’s Family Library feature, which will make sharing apps between up to six family members easier. All apps bought after July 2, 2016 will be automatically opted in to the service. Therefore, developers of apps purchased after the release date will be required to manually opt out of the sharing service, if they want their apps to remain exclusive to one device.
However, for apps bought before the allotted date, app developers will have to decide whether they wish to opt in to the service. Developers will be unable to restrict sharing of their apps again once they make the decision to support the Family Library sharing feature.
Google also announced this week that Android apps and the Google Play Store would soon be available on their Chrome operating system. A preview will be available to developers in mid-June, while Google said Android apps would become supported by Chrome OS "later in 2016".
