I created a new Unity Project which just has a simple Main camera and a Directional Light. I added the scene and chose Android as my build environment. When I "Build and Run" my Unity app always crashes and does not start the game. I tried building the same apk on other (non-tango) android device and it seems to load fine. I haven't even added my Tango prefabs yet (although i did try adding them but no luck). Am I missing something ? Has anyone else experienced this problem ?
P.S.: My other tango unity samples seem to run fine.
Try following the steps in https://developers.google.com/project-tango/apis/unity/unity-prefab-motion-tracking. They also have some suggested Player Settings for Default Orientation (Landscape Left) and Min API (17).
