Android Build Package Errors After Visual Studio Update: A Comprehensive Troubleshooting Guide

Introduction

Visual Studio updates can sometimes introduce unexpected errors during the Android build process. This guide provides a comprehensive set of troubleshooting steps to help you resolve any errors you encounter after updating to the latest version of Visual Studio.

Error Overview

When attempting to build a Release version Android package for a .NET8 MAUI project after updating Visual Studio, you may encounter the following errors:

  • resource mipmap/appicon (aka com.languageinuse.app:mipmap/appicon) not found.
  • resource drawable/liulogo (aka com.languageinuse.app:drawable/liulogo) not found.
  • failed processing manifest.
  • Could not find file 'C:\\Projects\\ERDevOps\\LIUApp\\LanguageInUse\\obj\\Release\\net8.0-android\\android\\manifest\\aapt\_rules.txt'.

Troubleshooting Steps

1. Verify Missing Resources

Ensure that your project contains the missing resource files, namely mipmap/appicon.png and drawable/liulogo.png.

2. Update NuGet Packages

Try updating the Android SDK and MAUI NuGet packages:

Update-Package Microsoft.Maui -Version 6.0.449
Update-Package Microsoft.Android.Sdk -Version 34.0.53

3. Clean and Rebuild Solution

Close and reopen your solution, then clean the solution and rebuild it. This will remove all intermediate files and potentially resolve any issues with the manifest file.

4. Check aapt_rules.txt File

Check if the aapt_rules.txt file exists in the obj\\Release\\net8.0-android\\android\\manifest directory. If not, ensure you have the Android SDK Platform Tools installed and attempt to rebuild the project.

5. Reinstall Android SDK Tools

Try reinstalling the Android SDK tools. This can be done through the Android Studio SDK Manager or the Visual Studio installer.

6. Update Visual Studio

If all else fails, try updating Visual Studio to the latest version.

Other Tips

  • Make sure that your project files and solution file are not corrupted.
  • Try building the project on a different machine or VM.
  • Contact Microsoft Support for further assistance.

Conclusion

By following these steps, you should be able to resolve the errors that you encounter in your Android build package after updating Visual Studio. If you continue to experience issues, don't hesitate to seek professional assistance.
