Although the new feature has yet to be announced, Google is beginning to allow Google+ users to install Android apps right straight from the Stream. I personally tested the feature this morning and was able successfully install a number of apps on my Android smartphone. Many users will definitely find this new feature nifty, since it will now be easier to share apps on Google+. This also saves a lot time since we can now install or purchase apps directly from the Stream.
To try the new feature, just paste a URL of an app that you want to share on Google+. You’ll then notice that Google+ can automatically recognize the link and will soon embed the Install/ Buy button, as seen above. Clicking the install or buy button loads up the app on Google Play and it will then ask you to confirm the installation process. Interestingly, as noted by The Next Web, hitting +1 on an app in Google Play will share the app on Google+, but will not embed the Install/ Buy button.
