如果你的C++代码中出现了很多C++特有的库，例如<iostream>,<list>等，那么你还需要在jni的文件夹下添加一个Application.mk文件，文件内容为：
APP_STL := stlport_static
APP_STL := gnustl_static
我的Application.mk
APP_ABI := armeabi
APP_STL := gnustl_static #GNU STL
APP_CPPFLAGS := -fexceptions -frtti #允许异常功能，及运行时类型识别
APP_CPPFLAGS +=-std=c++11 #允许使用c++11的函数等功能
。
我的Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := TuziHelper
LOCAL_SRC_FILES := hello-jni.c fstrcmp.c Gethwaddr.cpp HttpParser.cpp Implementation.cpp Main.cpp md5.cpp \
Event.cpp ThreadImpl.cpp SystemClock.cpp Thread.cpp ThreadSchedImpl.cpp TuziPlayServer.cpp \
