Problem building for Android: Resources\values\colors.xml : error APT2126

Hi HH!

The error APT2126 indicates a problem with AAPT (Android Asset Packaging Tool) when processing your XML resource files in your MAUI project, especially in colors.xml. Here are some possible causes for this issue:

• Invalid XML syntax in colors.xml: Check for missing closing tags, incorrect nesting, or unescaped characters
• Unsupported color format: The file might be using color values that Android doesn't recognize
• Duplicate resource names: You may have two color entries with the same name
• Invalid resource references: Check for broken references to other resources

Here's some solution you can try:

1. Validate your colors.xml file:

Open Platforms/Android/Resources/values/colors.xml and ensure:

• Proper XML structure with <resources> root element and XML declaration
• Valid color values (hex formats: #RGB, #ARGB, #RRGGBB, #AARRGGBB)
• Unique names for each color entry
• No special characters or spaces in color names
• No Android reserved keywords

Example of correct format:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="primary">#6200EE</color>
    <color name="primary_dark">#3700B3</color>
    <color name="accent">#03DAC6</color>
</resources>

2. Clean and Rebuild:

For MAUI projects in VS Code, use these commands:

dotnet clean
dotnet build

3. Check for Common Issues:

• Missing XML declaration: Add <?xml version="1.0" encoding="utf-8"?> at the top
• Unclosed tags: Every <color> must have </color>
• Invalid characters: Remove any non-standard quotes or invisible characters

4. Last Resort - Recreate File:

If the file appears corrupted:

• Delete colors.xml
• Run dotnet clean
• Recreate with minimal content and test

I hope this help, if the problem persists, please share:

• The exact content of your colors.xml file
• Your project's target framework (e.g., net8.0-android)
• The complete error stack trace
• Your MAUI workload version (dotnet workload list)

This will help me provide more specific assistance!
