1、Android.mk写法:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:= pn547_iic_test_app.c
LOCAL_MODULE:= pn547_test
LOCAL_MODULE_TAGS := optional
include $(BUILD_EXECUTABLE)
2、测试用c文件写法
/*
* Android.mk //TODO:Here is makefile reference
* LOCAL_PATH:= $(call my-dir)
* include $(CLEAR_VARS)
* LOCAL_SRC_FILES:= pn547_iic_test_app.c
* LOCAL_MODULE:= pn547_app
* include $(BUILD_EXECUTABLE)
