*
 * When multiple Android builds run in parallel and share the same `ANDROID_HOME`, the Android Gradle Plugin
 * may attempt to download and install SDK components (platforms, build-tools, platform-tools) simultaneously.
 * This can cause race conditions leading to:
 * - `FileAlreadyExistsException` when extracting files
 * - Corrupted installations (e.g., "Build-tool X has corrupt source.properties")
