Microsoft's Android app push continued this week with a new version of Lync Mobile that adds support for tablet-sized devices, among other enhancements. Microsoft had previewed this app three months ago at Lync Conference 2014.

"Today we're releasing a new Lync app for Android that supports both phones and tablets," Lync Mobile product manager Barak Manor writes in a new post to the Office Blogs. "In addition to Android tablet support, our team also added two great features to enhance your conversation experience—the ability to add participants to an ongoing conversation and the ability to start an ad hoc group conversation."

Beyond tablet support, most of the features are unchanged from previous versions. But the following are new:

Add people to a Lync meeting. You can now add participants to an ongoing Lync Meeting.

Start a Lync conversation whenever you want. Instead of forcing you to schedule meetings, Lync Mobile now supports ad hoc conversations: Just go to your contact list, select one or more people, and invite them via IM, call, video, or email.

Lync Mobile for Android handsets and tablets requires Android 4.0 or higher, a dual core 1.2 GHz processor or higher, and one or more VGA (or better) cameras. This version of the Lync application is not supported on devices with Tegra 2 chipsets.

You can download Lync Mobile from the Google Play Store.
