The build for my mobile xamarin app hangs always at this point in the flow:

With verbosity set to detailed this is show when hanging:

I'm stuck at the moment since the deploy does not continue:

I have some crazy error build problems with 2017 too and when i try to build on 2015 the program displayes the correct error. after i fix it the build was succecfull - CDrosos
Have you tried uninstalling from device - unplugging and replugging device - uninstall shared mono rumtime from device? - woelliJ
In retrospect it seems that it occurred after I ad-hoc installed the same .apk to the phone. I tested if it was possible to install a signed .apk from a website download and yes that worked fine. But after this install the deploy started failing. I deleted the app used ES File Manager and Clean Master to remove leftover files, rebooted PC and Phone but nothing helps. - Paul Sinnema
I';ve come to the point where I have to decide to revert to factory settings. I'm going to do that tonight. If anyone can give me a hint what might be the problem I would certainly like to know. - Paul Sinnema

For others having the same problem it is worth checking out this report on the Visual Studio Developer Community site: https://developercommunity.visualstudio.com/content/problem/211740/apk-signature-fails-apksignerbat.html

There seem to be two potential workarounds:

  1. Replace the last line of the apksigner.bat with call "%java_exe%" %javaOpts% -classpath "%frameworkdir%" -jar "%jarpath%" %params%.
  2. Remove all versions of the JDK/JRE except a single instance of JDK8.

I was using Android Pixel 3 Emulator (Xamarin) without any issues and one day it suddenly ran into this issue. After trying several options - only option worked for me was completely deleting the emulator I was using and re-installing a new emulator.

Everything is back to normal - of course you will loose all of the previously deployed apps. But for Xamarin learners like myself it isn't a big issue.
