Ensighten Mobile: A whole new level of mobile marketing agility. Real-time Mobile App Tagging. Online businesses are facing the largest fundamental market shift ever: the explosive growth of mobile browsing on tablets and smartphones. Recent growth estimates put mobile commerce at $31 billion in the U.S. by 2016.

And even minor app changes require app resubmission, delaying the availability of the update in stores. See the Results of Tag Changes Instantly. With Ensighten Mobile, no source code is modified, allowing you to bypass the mobile app update process and associated delays. See the immediate impact of tag changes across all users and data.

ExoPlayer supports features not currently provided by MediaPlayer, including Dynamic adaptive streaming over HTTP (DASH), SmoothStreaming and Common Encryption.
