The error "Namespace not specified. Please specify a namespace in the module's build.gradle" indicates that your Android project is missing a namespace declaration in the build.gradle file. Here's how to fix it:

1. Locate the build.gradle file:

The file you need to edit depends on your project structure:

Single module project: The build.gradle file should be located at the root of your project directory.
Multi-module project: The build.gradle file you need to modify will be specific to the module experiencing the namespace issue. It's usually located within the module's directory (e.g., app/build.gradle).
