Visual Studio 2015 Xamarin deploy fail without any error message

Question

I just installed VS 2015, the installation was finish (after some fail time caused by the slow network, I run setup again).

I create a project as Adroid > A

Answer 1

In the Android App project Properties in Visual Studio I had to go to Android Options>Advanced and make sure the Support architectures had the architecture of my AVD checked.

In my case this was x86_64 (which, by the way, does not have a particularly discovereable method of installation - took me days).
