android 2.2 wifi 框架

最终通过：

C++层：：：

frameworks/base/core/jni/Android.mk

LOCAL_SRC_FILES:= android_net_wifi_Wifi.cpp 。。。。。

//包括该目录下所有文件C++

LOCAL_SHARED_LIBRARIES += libwifi，libwpa_client，libhardware_legacy。。。。。

//链接相关动态库（几乎所有）

LOCAL_MODULE:= libandroid_runtime

//生成共享库名称：
include $(BUILD_SHARED_LIBRARY)

include $(call all-makefiles-under,$(LOCAL_PATH))

wifinative 调用下层JNI，

wifi.c链接动态库libwpa_client.so 被添加到libnetutils.so

hardware/libhardware_legacy/Android.mk

SAVE_MAKEFILES := $(call all-subdir-makefiles)

LOCAL_SHARED_LIBRARIES := libutils libbinder libcutilslibwpa_client

include $(SAVE_MAKEFILES)

LOCAL_MODULE:= libhardware_legacy

include $(BUILD_SHARED_LIBRARY)

./hardware/libhardware_legacy/wifi/Android.mk
