App size is too much

Hi there,
I am trying to integrate MSDK in my project, I tried merging MSDK v5 sample project with my own project. MSDK Sample project itself takes about 150MB when I get APK file. What I need is I only need to get Remote Controller joysticks values and nothing else. Is there a way to reduce the size by excluding anything from the sample project? And what I need to do? Thanks.
