wrong android sdk requirement

[HobDev]

Type: Bug

I recently installed Visual Studio code after installing .NET 9 on a clean PC. When I check Android environment it always show that the Android SDK version 34 is not installed.
But it should check for Android SDK version 35 which is already installed and also the path is set in VS Code.

Extension version: 1.5.34
VS Code version: Code 1.95.3 (f1a4fb101478ce6ec82fe9627c43efbf9e98c813, 2024-11-13T14:50:04.152Z)

@HobDev: could you please provide the contents of the "Output" panel (Ctrl+Shift+U, then select ".NET MAUI" from the drop-down)?

For example, for reference, I followed the MAUI installation instructions:

1. Created a new Dev Box instance with just VSCode installed.

2. Installed .NET 9 from dotnet-sdk-9.0.100-win-x64.exe

3. Installed OpenJDK 17.0.13 from: https://learn.microsoft.com/en-us/java/openjdk/download#openjdk-17

4. Installed the MAUI workload:

   dotnet workload install maui
   

5. Installed the Android SDK:

   mkdir -p ${env:LOCALAPPDATA}\Android\Sdk
   dotnet new android -n provision-helper
   cd provision-helper
   dotnet build -t:InstallAndroidDependencies -f:net9.0-android -p:AndroidSdkDirectory=${env:LOCALAPPDATA}\Android\Sdk -p:AcceptAndroidSDKLicenses=True

6. Within VSCode, installed the .NET MAUI extension

7. Opened the provision-helper project created in (5), then Ctrl+Shift+P > .NET MAUI: Configure Android > Refresh Android environment

8. The results are written to the "Output" panel (Ctrl+Shift+U, then select ".NET MAUI" from the drop-down):

IMPORTANT:
- If you are sharing the Android SDK location with Android Studio, the recommended way to install/update the SDK and accept licenses is by using Android Studio.
- If you are sharing the Java SDK location with Visual Studio, the recommended way to install/repair the SDK is by using the Visual Studio installer.
 
SUGGESTION:
- Android SDK - There are optional Android SDK components required for emulator usage that we recommend to installed/upgraded: "emulator" "system-images/android-35/google_apis/x86_64".
	1. Install the Android SDK components:
		- From the command palette, choose '.NET MAUI: Configure Android', select 'How to configure Android', and follow the instructions.
		- Alternatively, you can try installing the components by opening a Terminal, navigating to directory 'C:\Users\jopryo\AppData\Local\Android\sdk\cmdline-tools\12.0\bin' and then running: 'sdkmanager "emulator" "system-images;android-35;google_apis;x86_64"'. Then, from the command palette, choose '.NET MAUI: Configure Android', and 'Refresh Android environment'.

I do not see any messages stating that "Android SDK version 34 is not installed".

[jonpryor]

Howver, with respect to my previous comment, if I update the .csproj file to instead have:

<TargetFramework>net8.0-android</TargetFramework>

that is, target .NET 8 instead of .NET 9, then .NET MAUI reports errors:

ACTION REQUIRED:
✗- Android SDK - Ensure that the required Android SDK components are installed: "platforms/android-34" "build-tools/34.0.0".
	1. Install the Android SDK components:
		- From the command palette, choose '.NET MAUI: Configure Android', select 'How to configure Android', and follow the instructions.
		- Alternatively, you can try installing the components by opening a Terminal, navigating to directory 'C:\…\AppData\Local\Android\sdk\cmdline-tools\12.0\bin' and then running: 'sdkmanager "platforms;android-34" "build-tools;34.0.0"'. Then, from the command palette, choose '.NET MAUI: Configure Android', and 'Refresh Android environment'.
Take into account that the .NET MAUI Android SDK recommends specific component versions and if you decide to not use them the building and debugging may not work well.

Then, from the command palette, choose '.NET MAUI: Configure Android', and 'Refresh Android environment'.

We thus need to re-run the InstallAndroidDependencies target:

dotnet build -t:InstallAndroidDependencies -f:net8.0-android -p:AndroidSdkDirectory=${env:LOCALAPPDATA}\Android\Sdk -p:AcceptAndroidSDKLicenses=True

Note -f:net8.0-android instead of the original -f:net9.0-android. Alternatively, if this is just a .NET for Android project, and <TargetFramework/> (singular) is used and <TargetFrameworks/> (plural) is not used, then the -f … value may be omitted entirely.

Now when Ctrl+Shift+P > .NET MAUI: Configure Android > Refresh Android environment, I get:

ANDROID ENVIRONMENT STATUS: 12/2/2024, 8:05:59 PM

		✓ platform-tools - INSTALLED (version '34.0.5')
		✓ cmdline-tools/11.0 - INSTALLED (version '11.0')

Notice that platforms/android-34 is now INSTALLED.

The shorter version is that the InstallAndroidDependencies target only installs the dependencies required to build the project upon which the target is run. Dependencies will vary based on $(TargetFramework) version: .NET 8 requires android-34, .NET 9 requires android-35, .NET 10 will probably require android-37, etc. Open or create a new project, and a possibly different set of dependencies will be required.

@jonpryor Thanks for detailed explanation. You are correct the issue is only with the project which I upgraded from .NET 8 to .NET 9. Other projects correctly recongnize the latest version of Android SDK. Do I have to move the code of the effected project to the project which is created with new template. Can't I fix this issue in the same project. I already replaced the net-8.0 references with net-9.0 in csproj and updated all the NuGets.

@mauroa, the 'needs-more-info' label has been removed upon receiving further response from the original bug filer.

I don't understand the question or scenario.

In particular:

Can't I fix this issue in the same project.

Why can't you fix it in the same project?

I think your scenario is:

1. You have a project which was initially created under .NET 8:
   • MAUI

     <TargetFrameworks>net8.0-android;<!-- other targets… --></TargetFrameworks>

   • or .NET for Android:

     <TargetFramework>net8.0-android</TargetFramework>

2. You then update it to target .NET 9:
   • MAUI

     <TargetFrameworks>net9.0-android;<!-- other targets… --></TargetFrameworks>

   • or .NET for Android:

     <TargetFramework>net9.0-android</TargetFramework>

   • Plus update other NuGet/etc. references to use .NET 9 versions
3. The project fails to build.

Is that your scenario? If so, what build errors do you see?

Or is that not your scenario?

@jonpryor

I have a project which was initially created under .NET 8:
MAUI
<TargetFrameworks>net8.0-android;<!-- other targets… --></TargetFrameworks>

I then update it to target .NET 9:
MAUI
<TargetFrameworks>net9.0-android;<!-- other targets… --></TargetFrameworks>

Plus update other NuGet/etc. references to use .NET 9 versions.

The project fails to build.

This is exactly my scenario.

If I manually set the Android location from the command Select Android SDK location to the same location as it is already set it recognize the installed Android SDK version 35 and ask for correct requirement (version 35). But when I try to debug I get the following error.
C:\Users\spara\.nuget\packages\dependencies.gradle\8.6.0.1\buildTransitive\Dependencies.Gradle.targets(30,3): error : Could not find 7zip.exe in Xamarin installation

Get few warnings like
C:\Users\spara\repos\Dome-backend\Player\Player.csproj : warning NU1608: Detected package version outside of dependency constraint: Xamarin.AndroidX.Navigation.Common.Ktx 2.7.6 requires Xamarin.AndroidX.Navigation.Common (>= 2.7.6 && < 2.7.7) but version Xamarin.AndroidX.Navigation.Common 2.8.0.1 was resolved.

After a restart the VSCode again expect the wrong android sdk requirement as described in the issue. But still if I debug I get the same error as above. Below is the terminal output:

The terminal process "C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe -Command dotnet build -t:Run -p:Configuration=Debug -f net9.0-android -p:AdbTarget=-s%20MyAndroidVirtualDevice-API35 -p:AndroidAttachDebugger=true -p:AndroidSdbTargetPort=63786 -p:AndroidSdbHostPort=63786 -p:CustomAfterMicrosoftCSharpTargets="c:\Users\spara\.vscode\extensions\ms-dotnettools.dotnet-maui-1.5.34-win32-x64\dist\resources\Custom.After.Microsoft.CSharp.targets" -p:MauiVSCodeBuildOutputFile="C:\Users\spara\AppData\Local\Temp\dotnet-maui\maui-vsc-6d445146-24ed-46b9-9ce8-4626a384658f.json" -p:AndroidSdkDirectory="c:\Users\spara\AppData\Local\Android\Sdk" C:\Users\spara\repos\Dome-backend\Player\Player.csproj" terminated with exit code: 1.

I installed 7Zip on my windows 11 machine. Now I am getting new error:

Get this error with .net 8 and .net 9 both.

[HobDev]

The actual issue of wrong android sdk requirement is resolved. I don't able to build because of the NuGet Stripe.MAUI which is not compatible with .NET 9.
