Fix for Android Example Project Gradle Issues

[vicajilau]

Summary

The Android directory in the example project was found to have outdated Gradle configurations, preventing compatibility with newer versions of Java and causing build issues. To resolve this, the Android folder was removed and regenerated using Flutter's CLI tool.

Steps Taken

1. Remove the existing Android folder from the example project.
2. Regenerate it with the following command:

   flutter create --platforms=android .
   

Steps Taken

• Java Compatibility: The regenerated Android project now compiles successfully with newer versions of Java, ensuring compatibility with Java 21 and beyond.
• Gradle Version Alignment: The updated project uses a modern Gradle version that aligns with Flutter's latest tooling, as described in The Flutter and Java 21 Mystery.
• Improved Build Process: This fix not only resolves compatibility issues but also modernizes the Gradle setup for better stability and alignment with best practices.

Conclusion

The changes provide a more robust and forward-compatible configuration for the example project's Android build.
