When trying to deploy an app in Android Device, VS is stuck here:
1>C:\\Users\\George\\AppData\\Local\\Android\\android-sdk\\build-tools\\23.0.1\\zipalign
I came across the same issue in Visual Studio 2015 using any emulator. In my case, it turned out that I had to change a packaging option to get rid of the problem.
The deployment appears to be a touch slower, however, the emulator executes the software much faster. Enjoy!
