The project Nieron.Android in the above test solution is being built twice. Overall, this customer has been experiencing slow build and deploy times with his project. I noticed that rebuild times were not as fast as they could/should be, IOW not much faster than the initial build/deploy times after a clean build with the app not installed on the device yet.

I have checked this issue with "attached project" and i am able to reproduce this issue.

Steps to reproduce:

1) Open attached project on VS2013.
2) Build/ Deploy attached project.
3) Open output window and look for "Build Started".
