出现的问题：如果app游戏时正好网络处于开启状态，则运行正常。反之，则在android logcat输出signal11(SIGSEGV) at 0x00000000(code=1)

完整的排错过程如下
1, android debug模式查看具体出错的问题
貌似不是在android层, 确定为cpp代码出了问题；
2. appdelegate.cpp
CCLog("test")
没有打印出来，仍然直接报错
3. 继续log输出
System.loadLibrary("game");
Log.i(TAG,"android loadLibary done");
logcat能够输出相关代码，说明android层的代码都执行了，现在代码运行到了cpp层；
4. 继续跟踪jni/game/main.cpp
Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeInit
printf("test")
log cat没有显示print信息
这里一直对cocos2dx在android输出存在疑问。后来在application.mk添加了相关的设置仍然看不到log输出。
5. 采用
coco2d:cclog("test")
情况依旧
6. 开始排除jpush第三方推送jar, so库是否存在问题。
删除libs/libsys.so (jpush的so文件)
删除jpushInterface.init(this)
7. 继续在jni/game/main.cpp
使用ccmessagebox();
没有显示弹出窗口提示；
8. 修改application.mk
LOCAL_CFLAGS += -DCOCOS2D_DEBUG=2
没有结果，问题仍然存在
9. libegl loaded /system/lib.egl/libegl_viviante.so,
如果关闭网络，则没有显示加载上述的so文件
10. 打开jpush.setDebug(true);
在无网络情况下，显示sis error
11. 使用ndk-stack来查找崩溃
./adb logcat|ndk-stack -sym /Users/chenxu/work/c++/cocos2d-x-2.1.4/work/doudizhu/proj.android/obj/local/armeabi/

真正崩溃原因，这次是冤枉了jpush等第三方库，是android工程编写有问题。
原因是android启动后立即监控网络状态，如果网络为断开状态，则通过jni call cpp, 后者调用dispatchNetwork()函数，通过创建一个message丢入队列，界面线程pop消息之后，画出网络错误提示界面提示。
问题在于：这些都是多线程处理的，即android层由独立线程监控网络状态, cocos2dx界面层由独立线程运行，其中后者在收到网络错误时候，需要有关的未初始化实例来创建消息，导致了空指针的错误。 fatal signal 11(SIGSEGV)
最后解决办法：只有确定网络ok, 并且用户成功登陆后，cpp层采取调用原生android层，去监听网络状态。这样可以避免前面网络未建立就立刻通知界面的错误；
ndk-stack是个好东西，对于android异常崩溃能够提供call-stack，有效确定代码的出错位置；
