The Android. mk file is used to describe the project organization and Compilation Method to the compilation system. It is actually a small part of the GNU make file, which will be parsed once or multiple times by the compilation system.

The content of this file is as follows:

 

LOCAL_PATH: = $ (call my-dir)

This line is used to specify the current directory, that is, to assign the current directory $ (call my-dir) to the variable LOCAL_PATH, so that you can find the source code and the corresponding resource file.

 

 

Include $ (CLEAR_VARS)

Clear the temporary variables used previously.

 

 

LOCAL_STATIC_JAVA_LIBRARIES: = libarity

Use a static JAVA library named libarity.

 

 

LOCAL_SRC_FILES: = $ (call all-java-files-under, src)

This indicates the file to be compiled, that is, the file list of the source code. Compile the java source code in all src directories.

 

 

LOCAL_PACKAGE_NAME: = Calculator

This indicates the name of the compiled package. The name of the computer package is calculator.apk.

 

 

Include $ (BUILD_PACKAGE)

Here is the rule for compiling and generating packages. Its definition is also defined in config. mk, as follows:

BUILD_PACKAGE: = $ (BUILD_SYSTEM)/package. mk. This file defines in detail how to generate a package file.
