Gradle is a JVM-based build system that enables developers to write high-level scripts that can be used to automate the process of compilation and application production. It is a flexible plugin-based system, which allows you to automate various aspects of the build process; including compiling and signing a
.jar, downloading and managing external dependencies, injecting fields into the
AndroidManifest or utilising specific SDK versions.
GUID (or UUID) is an acronym for 'Globally Unique Identifier' (or 'Universally Unique Identifier'). It is a 128-bit integer number used to identify resources.
