android-cmake-project

We can read and modify android native C/C++ code through this project. We can compile our own Android C/C++ code to run on Android devices. Of course, all of this is based on CLion, thanks to the CLion team.

• Automatically finds the path to the module.
• Automatically parses the module's android.mk or android.bp file.
• Automatic resolution of module dependencies.
• Automatically adds the module and its dependent module's C/C++ source files.
• So you can use CLion's auto-jump feature. This is a great help for us to read the code.
• I configured toolchian to compile our own C/C++ programs and to rely on Android's native libraries.

For Android.mk:

• Only simple built-in functions for makefiles are supported

For Android.bp:

• Some bp file styles are not supported.

May later use soong to solve these problems.

Test Environment

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

Depend

• Fully compiled android source tree
• Linux: ${your android source path}/prebuilts/clang/host/linux-x86/clang-xxxxxx
• Windows: Android NDK

Description

• .idea
  I ignored some folders by default. They defined in .idea/misc.xml.

How to use it

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

Why do you need it

It can help CLion to generate the file map correctly. It can conveniently help us develop our own Android Native Service.
