The Android.mk file is a small fragment of the GNU make file that is used to describe the project's organization and compilation to the compiling system, and is parsed one or more times by the compiled system.

The contents of this document are as follows:

Local_path: = $ (call My-dir)

This line is used to specify where the current directory is, that is, to assign the current directory $ (call My-dir) to the variable Local_path so that the source code and corresponding resource files can be found.

Include $ (clear_vars)

Clears the temporary variable used earlier.

Local_static_java_libraries: = libarity

Use a static Java library with the name Libarity.

Local_src_files: = $ (call All-java-files-under, SRC)

Here is a file that indicates the need to compile, that is, a list of files that indicate source code. Here the Java source code is compiled for all SRC directories.

Local_package_name: = Calculator

This indicates the name of the compiled package, and the package name of the calculator is calculator.apk.

Include $ (build_package)

Here is the rule that includes compiling the build package, and its definition is defined in CONFIG.MK as follows:

build_package:=$ (Build_system)/package.mk. This is where the file is defined in detail to generate the package file.
