C_INCLUDES must be under the source or output directories

What the Android NDK error "C_INCLUDES must be under the source or output directories" actually means and how to fix LOCAL_C_INCLUDES paths.

The “C_INCLUDES must be under the source or output directories” error usually means that the sources are not listed under LOCAL_C_INCLUDES:

LOCAL_C_INCLUDES += \
    $(LOCAL_PATH) \
    $(LOCAL_PATH)/src

But watch out for symlinks as well: the same error appears when the folder was created as a symlink, so keep that case in mind too.
