  First of all better set LocalhostIp as your network ip

  private const string LocalhostIp = "192.168.1.XX";
  

  Secondly in some cases visual studio cannot attach to the emulator's debugger. So open the emulator first, wait it to settle down then start your app.

  Thanks Alper, There does not seem to be a way to reply to your suggestion, and the "Answer" button below is disabled, only the "answer and close" is enabled. This is NOT closed. See:

  OK, I changed toe LocalhostIp to be the machine running my star.Web.Host instance.

  However, starting the emulator first causes studio to exit with an "error" that the emulator is already running, see below. I tried this both with F5 debug mode and a simple "deploy to device", same result with both.

  uninstall the existing application on the emulator (if exists) close visual studio delete all bin & obj files (you have a bat file for it in solution root folder) retry. if not works, create a new emulator with the latest SDK

  OK, what the heck, I guess it is worth a try. I started the LogCat on my Android and I noticed that the AspNetZero App was crashing after attempting some ClientUser interaction of some sort. The stack-trace information was not very precise, but showed that the application was crashing.

  if not works, create a new emulator with the latest SDK What do you mean by this. Create emulator? I use the emulators that are available from Xamarin, I don't create them as far as I can see.

  I'll let you know, of course, if I find a solution. I am also suspecting the Visual Studio-2017-next Preview edition. It should not be the probelm, but... Thanks again.

  OK, progress after the delete/rebuild:

  I can deploy with the VS-debugger to a real Android 7 SDK24 phone. The App now gives me a reasonable error message:

  I is attempting to call:

  GET http://192.168.2.107:22742/AbpUserConfiguration/GetAll => Call Failed.

  Well, as far as I can see (test, code search) , this API does not exist in the star.Web.Host

  Does it?

  Then upon "continue from dialog" it crashes here:

  09-26 20:28:32.980 E/mono-rt (27469): [ERROR] FATAL UNHANDLED EXCEPTION: System.Exception: Set configuration before using remote localization! NOTE: This is at line 42 in Mobile.Shared ...Localization.L.cs

  Perhaps you need to test/check again since there have been recent breaking changes in androids 8 SDKs.

  (Good to hear it shows a user friendly error message. so I guess the problem was old bin & obj files.)

  Debugging & Connecting to Xamarin App

  To connect from Xamarin app to the host; you can try several tests

  1. Try to open the URL in your development computer's browser http://192.168.2.107:22742/AbpUserConfiguration/GetAll
  2. Try to open the same URL in your phone.

  • Never use your mobile's data connection, to be able to debug from your android device, your android mobile phone must be in the same WiFi (turn off the data network and enable the WiFi)
  • Do not start Web.Mvc or Web.Host project via Visual Studio. Default settings of Visual Studio does not allow external connections. For more info you can read External Network Access to Kestrel and IIS Express in ASP.NET Core

  The related docs are Xamarin Development Guide and Developing Step By Step Xamarin.

  Thanks alper for the great infos! I am one step ahead of you though. I did everything you suggested already before I wrote :-) You can also see in the logs and in the stack above that the mobile client is indeed making the connection with the host. It is apparently not a connection problem. That is why I answered that

  http://192.168.2.107:22742/AbpUserConfiguration/GetAll

  cannot be found. I cannot call this from anywhere.
  Question: Where can I set a debug point to see this entrypoing in the Web.Host?

  Also, as you noted, when I test the Web.Host using VStudio, the default route does not work:

  http://localhost:22742/

  gives me the message "unable to handle this request".

  http://localhost:22742/swagger works fine.

  I can surely find and fix this myself, but I am using the UNCHANGED base code from ASP.NETZero: I have not made any changes. So why isn't the default route working? Ideas?

  Question: I assume that the default route http://localhost:22742/ should simply to the HomeController in Web.Host.

  Thanks again!

  it's not related with the code base. As I stated, don't run Web.Host via Visual Studio. make a new batch file with the below contents and run that for starting Web.Host.

  CD /D "C:\MyProject.Web.Host"
  SET ASPNETCORE_ENVIRONMENT=Development
  SET ASPNETCORE_URLS=http://*:22742
  dotnet run
  

  Download start-host.bat

  Thanks alper. Yes, see my first post. This is precisely what I did. That is not the problem. Also above, you can see in the log/stack that the connection is working fine.

  The problem, I think, is that it is not finding the following route -- and I don't see it in the code either:

  http://192.168.2.107:22742/AbpUserConfiguration/GetAll

  So my questions above are still the same. Can you help me out with them? THANKS!

  Hi,

  I guess you are using Merged version of the project.

  So for your last question, http://localhost:22742/ doesn't navigate to HomeController (this is disabled by default) Try opening http://localhost:22742/AbpUserConfiguration/GetAll/ You should see some Json response

  See my working log output. A request is being made to http://192.168.1.38:22742/AbpUserConfiguration/GetAll And route matched with {action = "GetAll", controller = "AbpUserConfiguration", area = ""}.

  Hi alper. Many thanks. This helps. I am indeed NOT getting that response. I'll investigate and get back to you here...

  From your log above:

  INFO 2018-09-26 12:44:07,334 [9 ] uthentication.JwtBearer.JwtBearerHandler - Successfully validated the token. I'm thinking that this may be where the problem is in my case. How does the mobile client get a valid token without logging in first? Hmmm.

  Strange, the mobile app (emulated) is crashing here (see screen shot). I am using the newest aspnetzero with no modifications in these libs. Any idea why it is not getting its config?

  Hi,

  Alper will help you with the latest problem about Configuration being null.

  For this one;

  I'm thinking that this may be where the problem is in my case. How does the mobile client get a valid token without logging in first? Hmmm.

  When you authenticate once, the token is stored in the app and it is used for the next time. So, there might be something left in the app from an older request.

  Thanks! But how can I authenticate the app when it never starts? I never get a chance to authenticate, since the app never gets past the init screen before it crashes. Have deleted all bin/obj and created new android emulators, so a "stale cache" cannot be the problem.

  Thanks for any tips!

  your problem is still connecting to the Host. When I check your exception stack I see HandleFlurlHttpException the highlighted line you captured is trying to translate the text "Error" but as the app couldn't get the translation Json it throws exception. So what you need to do is, UserConfigurationManager.cs or WebRequestExecuter.cs. It's definately connection issue!

  Thanks alper. It was not a communication error. It works fine if I use .Web.Mvc as the target instead of Web.Host. I have been using host the whole time, since that is what it says to use in the documentations. All of this above, and always using Web.Host. The APIs it was failing on are not available on Web.Hos, so the connection was made, and then the API not found which responded with internalServerError...

  Thanks again for your help. Moving on.

  Dear alper, OK, this may be another problem, but do you have any idea where these port numbers are comming from (see screen shot). I have not changed anything in the mobile app, and the user-login connections are now failing due to ports that do not exist. A search through all files did not lead to any clues. THANKS

  this is where the Xamarin gets the Host URL https://github.com/aspnetzero/aspnet-zero-core/blob/dev/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Application.Client/ApiClient/ApiUrlConfig.cs#L8

  Thanks Alper,

  Yes. I have not modified that file, and the admin GUI on the mobile works fine, where I can also define a tenant and a user. But as soon as I try to login as that user, I get the error above. There is some funky manipulation of ports going on somewhere in the original source code (no mods by us), and it doesn't work :-)

  the URL can change on the fly within this method.

  Put a breakpoint to see if your tenant has a different base URL.

  Thanks. Yes, I'll put a breakpoint and debug this when I can ... this is a POC I wanted to get working, but not top prio with aspnetzero here at the moment so can't say. Thanks again.
