VS 2026 development of MAUI apps for mobile IS NOT POSSIBLE

This is a total mess - I just upgraded to VS 2026 community and .NET MAUI development is totally broken - it's not possible to install SDKs, it's keep failing with license acceptance error, of course I click "Accept" but it does not work. I tried multiple repairs/removals/installs through VS Android SDK Manager - the same error all the time.

I can't build the project: The Android SDK licenses acceptance failed. These must be accepted to continue using Android. For more details, check the .NET MAUI Output. Double-click on this message to try this again.

Android emulator (Pixel) cannot be installed: it downloads everything, unpacks and fails with cryptic error message.

SDKs cannot be installed properly with Android SDK Manager - there's a dialog box saying operation completed, but the status bar message says it's failed.

SDK command line tools cannot be found in any of the locations by Copilot, despite multiple repairs/reinstalls.

    Hi @Sergiusz ,

    Thanks for reaching out.

    It looks like the issues you’re seeing are related to Android SDK and emulator setup, as well as project compatibility, when using Visual Studio 2026 + .NET MAUI + Android:

    • License acceptance: Sometimes licenses don’t persist if the Java JDK version or SDK paths are mismatched.
    • SDK / Emulator failures: Android SDK Manager may show “completed” but fail in the background, and emulators might not start.
    • Project compatibility: MAUI projects targeting older .NET versions (like .NET 8) may not build reliably under VS 2026.

    To troubleshoot:

    1. Accept Android SDK licenses manually:
    sdkmanager --licenses
    1. Check that your SDK paths and environment variables (ANDROID_HOME, ANDROID_SDK_ROOT, JavaSdkDirectory) are correct.
    2. Use a newer Java JDK (e.g., Java 11 or 22) and re-accept licenses.
    3. Consider upgrading your project to .NET 9 or .NET 10 if possible.
    4. Delete and recreate Android emulators (AVDs).
    5. You can also try building and deploying via CLI (dotnet build, dotnet publish) to bypass IDE issues.

    If none of this works, report the problem through Microsoft’s official channels:

    Include your VS version, MAUI target, SDK paths, Java version, and error messages to help them track the issue.

    Hope this helps! If my answer was helpful - kindly follow the instructions here so others with the same problem can benefit as well.

    I noticed this during my nonsleepingfixmyproject session today...
    User's image

    AND I FOUND THE SUNOFABICH

    User's image

    "C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\36.1.30\tools\Xamarin.Android.Common.targets" is where my file was located (standard path I think).
    Is there a specific reason its only looking for "MAX" Java 6 or 7?
    Im having way over that, and since its a NEW Android Build Tool (latest), it seems weird Java 6 or 7 is standard included.

    I will test my solution by adding a bypass in my project.

    It sounds like you're experiencing several issues with .NET MAUI development in Visual Studio 2026, particularly with the Android SDK installation and license acceptance. Here are some troubleshooting steps that might help resolve these issues:

    1. Check Android SDK Tools: Ensure that you have the correct versions of Android SDK tools installed. You may need to install the following packages:
      • Android SDK Command-line Tools 5.0 or later
      • Android SDK Platform-Tools 31.0.3 or later
      • Android SDK Build-Tools 30.0.3 or later You can do this through the Android SDK Manager in Visual Studio.
    2. License Acceptance: If you're having trouble accepting the licenses, try running the SDK Manager as an administrator. This can sometimes resolve permission issues that prevent license acceptance.
    3. Repair Visual Studio: Since you've already tried repairs, ensure that you are using the Visual Studio Installer to perform a full repair. Sometimes, a complete reinstall of Visual Studio may be necessary if the installation is corrupted.
    4. Check Environment Variables: Make sure that your environment variables for the Android SDK are correctly set. The ANDROID_HOME variable should point to your Android SDK installation directory.
    5. Use Command Line Tools: If the GUI tools are failing, you can try using the command line to install the SDK components. Open a command prompt and navigate to your SDK tools directory, then run: 
         sdkmanager --install "platform-tools" "build-tools;30.0.3" "cmdline-tools;latest"
    6. Emulator Issues: If the emulator installation fails, ensure that your system meets the requirements for running the Android Emulator. You may also want to delete any existing AVDs and recreate them.
    7. Verbose Logging: Enable verbose logging in Visual Studio to get more detailed error messages. This can help identify the specific cause of the failures you're encountering.

    If these steps do not resolve the issues, consider checking the .NET MAUI documentation or community forums for additional support.
