NETSDK1178 android workload missing

[rene-descartes2021]

Android application type

.NET Android (net7.0-android, net8.0-android, etc.)

Affected platform version

.NET 8.0.201

Description

android and maui-android workloads are not listed in dotnet workload search. At this time I'd like to use the android workload and I assume it's in this repository. First time attempting something like this so I could be doing something wrong.

/home/user/.dotnet/sdk/8.0.201/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1178: You may need to build the project on another operating system or architecture, or update the .NET SDK

In my readings I see android workload available on other's Linux OS with .NET 8, so I presume the arm64 host architecture is the issue. Or some other unknown. I can see it on my Linux OS desktop (x86_64) with .NET 7.

If not supported on Arm64 I'd appreciate any tips on the problem area to look, in order to possibly contribute.

Steps to Reproduce

Reproduction steps:

$ dotnet new install Microsoft.Android.Templates
$ dotnet new android
$ dotnet restore
/home/user/.dotnet/sdk/8.0.201/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1178: The project depends on the following workload packs that do not exist in any of the workloads available in this installation: Microsoft.Android.Sdk.net8 [/home/user/dev/android/android.csproj]
/home/user/.dotnet/sdk/8.0.201/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): error NETSDK1178: You may need to build the project on another operating system or architecture, or update the .NET SDK. [/home/user/dev/android/android.csproj]

How I installed dotnet SDK:

$ mkdir $HOME/.dotnet
$ tar zxf dotnet-sdk-8.0.201-linux-arm64.tar.gz -C $HOME/.dotnet
$ export DOTNET_ROOT=$HOME/.dotnet

Previously I tried 8.0.101 and that didn't work so I updated to 8.0.201 with same results.

I think .NET Android will be supported on linux-arm64 in .NET 9, but isn't supported on .NET 8:
#8500

You could try the .NET 9 preview and see if that works.

Actually we have this change in the latest service release: https://github.com/xamarin/xamarin-android/releases/tag/34.0.79

Does dotnet workload install android --verbosity diag show the version of the android workload? 34.0.79 should have #8500 in it.

[rene-descartes2021]

Oh wow, lucky me, I had no idea this was a new feature. I'm fine waiting a bit.

Does dotnet workload install android --verbosity diag show the version of the android workload? 34.0.79 should have #8500 in it.

--verbosity diag doesn't print anything additional in my case. No other parameter or environmental variable I tried changed anything. So I started searching the files/manifests.

I noticed indication of the prior version being in the filesystem, and looking at 34.0.43 files I see it doesn't have linux-arm64 while 34.0.79 does.

~/.dotnet/sdk-manifests/8.0.100/microsoft.net.sdk.android$ ls
34.0.43  34.0.79

So I grep'd around for 34.0.43 and found this "baseline" manifest:

~/.dotnet/sdk-manifests/8.0.100/workloadsets/8.0.201-baseline.24114.5$ head baseline.workloadset.json
{
"Microsoft.NET.Sdk.Android": "34.0.43/8.0.100",
"Microsoft.NET.Sdk.iOS": "17.0.8478/8.0.100",
"Microsoft.NET.Sdk.MacCatalyst": "17.0.8478/8.0.100",
"Microsoft.NET.Sdk.macOS": "14.0.8478/8.0.100",
"Microsoft.NET.Sdk.Maui": "8.0.3/8.0.100",
"Microsoft.NET.Sdk.tvOS": "17.0.8478/8.0.100",
"Microsoft.NET.Workload.Mono.ToolChain.Current": "8.0.2/8.0.100",

So, maybe that is where the problem area is, that it's looking at the available architectures in the baseline version and not the most recent available?

Well, I'm fine waiting for the baseline to advance to 34.0.79, so I'll close this issue and will reopen if there is still problem then. Thank you!

It seems like if you did dotnet workload update --verbosity diag, it should update the contents of this file:

dotnet/sdk-manifests/microsoft.net.sdk.android/8.0.100/WorkloadManifest.json

And this file should change to 34.0.79, or the latest version. Does it not?

[rene-descartes2021]

dotnet/sdk-manifests/microsoft.net.sdk.android/8.0.100/WorkloadManifest.json

And this file should change to 34.0.79, or the latest version. Does it not?

I don't see that particular path, it's different on my system:

$ ls -l ~/.dotnet/sdk-manifests/
total 4
drwxr-xr-x. 16 user users 3452 Feb 14 18:25 8.0.100

Here are a few similar paths I see.

WorkloadManifest.json under sdk-advertising:

$ head -n 20 ~/.dotnet/sdk-advertising/8.0.200/microsoft.net.sdk.android/WorkloadManifest.json

Two versions of WorkloadManifest.json under sdk-manifests, the latter with linux-arm64:
