Android.mk file - including all source files in different folders and subfolders

Question

In writing an android .mk file, is there a short way to include many source files which are in different folders and subfolders? Like a loop or a code for iterating the folders?

Answer 1

FILE_LIST := $(wildcard $(LOCAL_PATH)/*.cpp)
FILE_LIST += $(wildcard $(LOCAL_PATH)/**/*.cpp)
FILE_LIST += $(wildcard $(LOCAL_PATH)/**/**/*.cpp)
LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)

Answer 2

You can use ** wildcard to include files from all subdirectories:

LOCAL_SRC_FILES += $(patsubst $(LOCAL_PATH)/%, %, $(wildcard folder/**/*.cpp))
