Custom gradle task which copies app-debug.apk to Desktop and renames it to Git's current checked out branch

build.gradle.kts

// 1. Add following snippet in your build.gradle.kts(:app)
// Run this command in terminal -> ./gradlew copyDebugApkToDesktop

// Note: It will replace "/" in your branch name with "-" as "/" creates a directory.
// fix/bug becomes fix-bug. You can adjust it as per your needs.

            "unknown_branch" // Default to a generic name if Git command fails
