Android NDK 同時編譯多個模塊

|-test
|---Android.mk |---Application.mk |---sub1 |------Android.mk |------main.c |---sub2 |------Android.mk |------main.c

拿上邊的文件結構為例

test/Android.mk

include $(call all-subdir-makefiles)

test/sub1/Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_CFLAGS += -pie -fPIE  
LOCAL_LDFLAGS += -pie -fPIE -llog
TARGET_PLATFORM := android-22 
LOCAL_MODULE := module1
LOCAL_SRC_FILES := main.c
include $(BUILD_EXECUTABLE)

test/sub2/Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
ARGET_PLATFORM := android-22
LOCAL_MODULE := module2
LOCAL_SRC_FILES := main.c
include $(BUILD_SHARED_LIBRARY) 

原理就是 all-subdir-makefiles 這個宏會返子文件夾下所有Android.mk文件的路徑
