Gradle is Android's official build system. It automates code compilation, dependency management, packaging into APK/AAB, signing, and running tests. Gradle uses scripts (build.gradle) written in Groovy or Kotlin DSL. It's a flexible and powerful tool that replaces older systems like Ant or Maven.

build.gradle (Project): GLOBAL configuration for all project modules.

What is applicationId in Android?

applicationId is the UNIQUE identifier of the app on Google Play Store and on device. Format: com.company.appname. Two apps with same applicationId cannot coexist. applicationId is defined in build.gradle: android { defaultConfig { applicationId 'com.example.app' } }. Don't confuse with code package name (can be different).
