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
None of the solutions present on the web(regedit, clean, uninstall, restart, etc...) solved the issue for me. I ended up reading through xamarin's bugzilla log and found that the solution is to have the emulator running prior to trying to deploy. If you simply build, then deploy and let visualstudio launch the emulator it will hang. However, if you launch the emulator from the Android AVD Manager then deploy via visualstudio, it will run deploy cleanly.
