ConferenceVision build

It was possible to build https://github.com/Microsoft/ConferenceVision

Some details doesn't work, but it builds and run and I was able to get a simple Achievement.

https://github.com/igorkovalchuk/ConferenceVision/tree/linux-build

README-LINUX.md

This application needs Android => 5.0 and it needs lot of Internal Storage to install. I've set 1.5 Gb

The build took 2.5 minutes.

P.S. Don't change the emulator's properties after you have created it, otherwise this application will crash when you open a camera. Probably it doesn't see the sdcard or a file storage after that.

build #993

I've moved to Xamarin.Android build #993 and Mono 5.14 and nuget,
including the new VSCode 1.25.1 and C# plugin and Monodevelop 7.5

Also I am using the dotnet sdk - it is necessary to build the netstandard2.0 projects and restore the nuget packages.

And I've updated the documentation:

P.S. Monodevelop 7.5 doesn't open the Droid projects.

issues :: AotAssemblies and release settings

Don't forget to use <AotAssemblies>false</AotAssemblies> when you build the release apk on Linux.
But I may be wrong, because things are changing from time to time.

Other settings in "Release|AnyCPU" section may include this:

    <DebugSymbols>true</DebugSymbols>
    <DebugType>pdbonly</DebugType>
    <Optimize>true</Optimize>
    <OutputPath>bin\Release</OutputPath>
    <ErrorReport>prompt</ErrorReport>
    <WarningLevel>4</WarningLevel>
    <AndroidManagedSymbols>true</AndroidManagedSymbols>
    <AndroidUseSharedRuntime>false</AndroidUseSharedRuntime>

    <AndroidKeyStore>True</AndroidKeyStore>
    <AndroidSigningKeyStore>/mypathtojks/my_xamarin_keystore.jks</AndroidSigningKeyStore>
    <AndroidSigningStorePass>mystorepass</AndroidSigningStorePass>
    <AndroidSigningKeyAlias>myandroidalias</AndroidSigningKeyAlias>
    <AndroidSigningKeyPass>mykeypass</AndroidSigningKeyPass>

<!--
    <AndroidSupportedAbis>armeabi-v7a;x86;x86_64;arm64-v8a;armeabi</AndroidSupportedAbis>
-->

    <AndroidSupportedAbis>armeabi-v7a</AndroidSupportedAbis>

    <AndroidLinkMode>SdkOnly</AndroidLinkMode>

You may try to use AndroidLinkMode = Full, but for me it doesn't work today.

issues :: msbuild :: "MonoAndroid,Version=v1.0" not found

If msbuild outputs the next error:

The reference assemblies for framework "MonoAndroid,Version=v1.0" were not found.

Please add the TargetFrameworkRootPath to your Droid csproj:

<PropertyGroup>
<AndroidSdkDirectory>/home/myuser/my-android-toolchain-sdk-path</AndroidSdkDirectory>
<TargetFrameworkRootPath>/usr/lib/mono/xbuild-frameworks/</TargetFrameworkRootPath>
</PropertyGroup>

Thanks to Nihal Talur for the TargetFrameworkRootPath advice.

xamarin-forms-android-linux-tools :: emulator path

If you have this message:

PANIC: Missing emulator engine program for 'x86' CPU.

The newest versions of SDK have a new path

${ANDROID_SDK}/emulator
instead of ${ANDROID_SDK}/tools

funny :: a-no-debugger-land

I have working almost a year on a Xamarin.Forms project where on Linux platform I don't know how to run a debugger. Now I have returned back to the Android, but now I tend to avoid the debugging but writing the logs))

I don't know, maybe it is possible to run the debugger on the Linux+Android+Xamarin.Forms platform, but I afraid that it will take a lot of time to configure, so I haven't configured it.

P.S. I've found an important project which solves this problem. I have not tried it on Linux.

8.0 build

On my previous xamarin-android I can't build and run 8.0 projects - I am getting this exception: I/MonoDroid( 2345): System.MissingMethodException: Method 'Android.Views.View.set_Focusable' not found.

So, I decide to try a newer build #610 (24 Oct 2017 14:05:40) - Revision: a08f8851e2db7c5c44ead3c9a29afc7c2ebc05e4
It works for me:
