Background

To import C/C++ code for Android Native using Clion, implement code hinting, custom module compilation.

Currently supports.

• Automatically find the path where Android.mk, Android.bp of the configuration module is located.
• Automatically parse Android.mk, Android.bp under the module path.
• Automatically parse the source and header files of the module.
• Automatically parse module dependencies, and dependent header paths.
• Automatically parse some (some syntax complex can't be parsed) C/C++ Flags.
• Generate rough CMakeList.txt via Android.mk, Android.bp.
• Configured global Clang environment to support cross-compilation of custom C/C++ projects on CLion (need to write CMakeList.txt by yourself).

Known issues:

• Complex syntax cannot be parsed.
• Android HIDL module does not parse properly.
• Cross-compilation may not work properly.

The above problem may have to wait for my new project AndroidCMakeSoong to be solved. For now it is still up to the point where it works.

• Most of the modules can parse the source files normally, and the header files can be parsed normally in most cases, so it is helpful for code hinting.
• The dependency part of the header file can also be parsed normally, so the hints for other modules can also be done, the most typical ones are libutils and libcutils.
• You can add your own C/C++ projects and easily configure dependencies to achieve code hinting accessibility.
• You can use CLion to compile your own C/C++ projects and then PUSH them to your own device for testing, no need to use mm anymore.

For pure use the CMake language has been very good, the project I have been using at work for two years and it is still good to use. Here are two screenshots.

1. code jumping.
2. Successful compilation of libcutils.so.

Install

git clone https://github.com/Ahren-Li/android-cmake-project.git

Dependency

• Complete compiled Android source code.
• For Linux: ${your source path}/prebuilts/clang/host/linux-x86/clang-xxxxxx, determine which version of Clang you are using
• For Windows: requires Android NDK R21+

Usage

cp -r $(path)/android-cmake-project/.idea $(android_source_tree)/
ln -s $(path)/android-cmake-project/CMakeModule $(android_source_tree)/CMakeModule
ln -s $(path)/android-cmake-project/CMakeLists.txt $(android_source_tree)/CMakeLists.txt

.idea Folders

I pre-configured part of the ignore folder for Clion and they are defined in .idea/misc.xml, which improves the loading speed.

Configure your project environment

Environment configuration path (2 options):

1. android-cmake-project/CMakeModule/android.env.cmake
2. touch $(android_source_tree)/android.env.cmake

Configure project modules

Module configuration path

1. android-cmake-project/CMakeModule/android.module.cmake

# Load the dynamic library libsurfaceflinger and its dependencies
parseAndroidMK(libsurfaceflinger ${MK_SHARED})
# Load the executable init and its dependencies
parseAndroidMK(init ${MK_EXECAB})

Explanation of the second parameter of parseAndroidMK

Configure your custom C/C++ modules

1. android-cmake-project/CMakeLists.txt has pre-written loading code.

if(EXISTS ${CMAKE_CURRENT_LIST_DIR}/android-test/CMakeLists.txt)
    add_subdirectory(${CMAKE_CURRENT_LIST_DIR}/android-test)
endif()

2. Create your own android-test folder

mkdir $(android_source_tree)/android-test

3. Refer to this CMakeList.txt to write your own module configuration.

Test Environment

• Android N/O/P/Q source tree
• Ubuntu 16.04/18.04/20.04
• Windows 10 && Android NDK R21
• Clion 2019.3.2
