Debian Stretch : anbox launch : intent error.

[Ecolow]

So, I installed anbox via anbox/anbox#300 (2nd comment) and via anbox installer (modified the script for Debian). Went relatively smoothly. However, anbox keeps on hanging than crashing at start up.

anbox session-manager output :
[DD 2017-08-19 12:22:41] [Renderer.cpp:165@initialize] Using a surfaceless EGL context
[DD 2017-08-19 12:22:42] [Renderer.cpp:248@initialize] Successfully initialized EGL

anbox launch :
[EE 2017-08-19 12:23:12] [launch.cpp:86@operator()] The intent you provided is invalid. Please provide a correct launch intent.
