After update my vs2017 to 16.6.5, and update google sdk-build-tools to 27.0.3, my project got a problem with debugging for my tablet. My project type is xamarin.android, I check it for xamarin.forms but debugging for my (not emulator) tablet is woks! Also before this update i don't have any problem with debugging. Here is my project output in diagnostic mode:

As you see my project compiled successfully!
I also tried copy zipalign.exe from Android\android-sdk\build-tools\27.0.3 to Android\android-sdk\tools, but it not works.
The problem was solved by changing the Debug option to X86! Thanks to https://www.c-sharpcorner.com/forums/deployment-error-with-xamarin-android-application
