While working with native code, i.e. C, C++ and RustLang, VS Code is the best IDE, but how to setup intelisense.

We can generate Compbd file from AOSP and include it in our project to proper intellisense.

Steps:

Pre: Generate desired AOSP image beforehand.

Now generate Compdb file using .

Compdb (compile_commands.json) Generator

Soong can generate compdb files. This is intended for use with editing tools such as YouCompleteMe and other libclang based completers.

compdb file generation is enabled via environment variable:

$ export SOONG_GEN_COMPDB=1
$ export SOONG_GEN_COMPDB_DEBUG=1

One can make soong generate a symlink to the compdb file using an environment variable:

$ export SOONG_LINK_COMPDB_TO=$ANDROID_HOST_OUT

You can then trigger an empty build:

$ make nothing

Note that if you build using mm or other limited makes with these environment variables set the compdb will only include files in included modules.

Or simply run

SOONG_GEN_COMPDB=1 m nothing

Then open the C/C++ Configuration (ui), go to advanced and set the compile_commands.json path to

out/soong/development/ide/compdb/compile_commands.json

Rescan intellisense

Reset the intellisense database, restart VSCode, and enjoy near-instant intellisense for any C/C++ source file in all of AOSP.
