Fin the problem with my Android MonoGame C# project

I followed that tutorial : [login to view URL] to be able to import my own models (from blender) in monogame. (It first failed with MG3.7 and finally succeded with 3.6). So I have the skinned model processor in the MG pipeline tool. I then created a very basic project (attached) but I'm unable to load the xnb model. To get the work you first need to run my project and tell me the error you get. You job will be to find the problem or help me to build a working project.
