Given a <Choose> definition in which a different AndroidManifest.xml is needed for a different App Store:

    <When Condition=" '$(AndroidAppStore)'=='GooglePlay' ">
        <None Include="Properties\AndroidManifest.xml" />
    <When Condition=" '$(AndroidAppStore)'=='Amazon' ">
        <None Include="Properties\Amazon\AndroidManifest.xml" />

Opening a Xamarin.Android project inside an IDE will then cause the following elements to be added:

    <None Include="Properties\AndroidManifest.xml" />


1. Open the .csproj and look over the <Choose> clause
2. Open the .sln in an IDE(VS/XS)
3. This will alter the .csproj and add another ItemGroup to the .csproj:

    <None Include="Properties\AndroidManifest.xml" />


It seems that the behavior of Pre Xamarin 4 builds did not have this behavior. Thus it is a possible regression in post Xamarin 4 builds.

Hi Jon,

<Choose> has never been very well supported in VS itself, and I'd say it's generally discouraged. 

In your particular case, you don't really need to conditionally include the items, only conditionally set the $(AndroidManifest) property instead. This will also make for a much more pleasant editing experience inside VS. Just let both items live in the .csproj without conditions:

		<None Include="Properties\AndroidManifest.xml" />
		<None Include="Properties\Amazon\AndroidManifest.xml" />

Then you can add a property group at the bottom of the .csproj like so:

		<AndroidAppStore Condition="'$(AndroidAppStore)' == ''">Google</AndroidAppStore>

		<AndroidManifest Condition="'$(AndroidAppStore)' != 'Amazon'">Properties\AndroidManifest.xml</AndroidManifest>
		<AndroidManifest Condition="'$(AndroidAppStore)' == 'Amazon'">Properties\Amazon\AndroidManifest.xml</AndroidManifest>

Note I changed the OutputPath too so when you build, you get distinct folders for each target store.

My suggestion is to even place this in a separate [App].targets file alongside the .csproj and import that instead:

	<Import Project="$(MSBuildExtensionsPath)\Xamarin\Android\Xamarin.Android.CSharp.targets" />
	<Import Project="App121.targets" />

Then, you can even include the .targets in the .csproj as a None item, and that will allow you to tweak the build process without having to unload and reload the project constantly.

This approach will work just fine for clean builds or rebuilds. 

you can do:

msbuild /p:AndroidAppStore=Google /t:Rebuild;Package


msbuild /p:AndroidAppStore=Amazon /t:Rebuild;Package

And get the two distinct APKs for each store using the respective manifest.

There is a minor issue in that creating the APK will not detect that you completely changed the AndroidManifest.xml in use and the output APK will not be generated, even if the target output APK doesns't exist (since it points to a different output folder when you build for, say, Amazon after building for Google). I'm attaching the repro project and a diagnostics log file for the Android team to look at and see if that can be fixed.

Workaround Solution

Should allow XA team to build and detect why the build isn't triggering when building with a different /p:AndroidAppStore value.

Comment 6 dean.ellis 2017-07-10 09:39:50 UTC
I have a feeling this is because the AndroidManifest.xml file in the Amazon folder has a modified date which is before the one in obj/Debug/android/ ..
Comment 7 dean.ellis 2017-07-10 11:23:47 UTC
@kzu I can't repo this on the latest. It seems to produce the issue in the test app. It produces the apk with the correct name in the Amazon directory.
