Description Jon Goldberger [MSFT] 2014-10-29 22:18:43 UTC
This seems similar to bugs 22834 and 23307 but it's happening when an Android project is in the solution but unloaded. You can build and deploy a WinPhone or iOS project but the popup comes up every time you build. 

## Steps to reproduce.

1. Disconnect from the internet on your windows machine. 
2. Open windows file explorer and delete the Xamarin.Android license file from %PROGRAMDATA%\Mono for Android
3. Load a sample XForms project (or other X-Platform project that includes a XA project) and, after killing the popup, unload the Android project.
4. Build and deploy the WinPhone project (or the iOS project if you can still connect to your build host)

# Expected result: Winphone app will build and deploy without being warned about Xamarin Android license requirements

# Actual result: WinPhone app builds and deploys but popup appears saying that a Xamarin Android license is required still pops up. 

## Note: It might seem that the build failed at first glance, but it doesn't.

Comment 3 Brendan Zagaeski (Xamarin Team, assistant) 2014-10-30 13:50:28 UTC
Regression status: sort-of a regression

## Old behavior

Xamarin (6b70b1e28c5a733187f7659220da4c0ff61ab2b1)

In Xamarin 3.5.58, the Xamarin.Android project will be automatically unloaded after the activation dialog is displayed and dismissed. Once the project is unloaded, no further dialogs will appear when cleaning, building, deploying, or debugging other projects.

## New behavior

Xamarin (21b7dba8736246dfd10e3f19a92ed68f1b30abfd)
Xamarin.Android (2a7b68212b17c903160fbd8e0106babb299d1be3)
Xamarin.iOS (3e201c8aa14879773f966f483329bcda49fd3a41)

Xamarin (8ca7d11db8a6f874c6cd2de6d9ca0f511867ce91)
Xamarin.Android (5474129af31e9d3a86cb7482c7c5c7a30ad315f1)
Xamarin.iOS (209abebbd8f1a292d042420edb45fa5fbd3f017b)

In the end, the new behavior is not really too different from the old behavior. The main change is that now you are allowed to keep the Xamarin.Android project open even when in the unlicensed state.

### Workaround

You can prevent the Xamarin.Android activation dialog from appearing when building other projects:

1. Manually unload the Xamarin.Android project
2. Quit Visual Studio.
3. Reopen the solution in Visual Studio.

Even though the workaround is fairly easy, this would still be a nice bug to fix, if possible. The build system is not interacting directly with the Xamarin.Android project when building the Windows Phone project, so from a user's perspective it's confusing that the activation dialog for Android appears.

Comment 4 Brendan Zagaeski (Xamarin Team, assistant) 2014-10-31 13:25:48 UTC
Just one quick additional comment since a customer pointed out that my previous comment might be a little ambiguous:

The ideal fix would be to keep the new behavior (allow loading Xamarin projects when you don't have a license), but also allow building non-Xamarin projects in the same solution without unloading the Xamarin projects. If that's not possible, then perhaps it would be possible to make it so unloading the Xamarin.Android project (without restarting VS) is sufficient.

A little further explanation: once you've loaded a Xamarin.Android project in the unlicensed state, you will get an activation dialog when building _any_ project in _any_ solution, even if the solution does not contain any Xamarin projects. You will need to quit and restart Visual Studio to stop the problem. 

Xamarin.iOS projects loaded in the unlicensed state do not cause this same persistent problem. It seems the Xamarin.Android VS extension does not unload itself in the same way as the Xamarin.iOS extension.
