char * s ="cainiaobuhuifei";
LOGI(s); 报：error: format not a string literal and no format arguments [-Werror=format-security]
找到的解决方法为：
as of Android NDK revision 9, the followingshould be added to Android.mk as a work-around for the quoted error.
"LOCAL_DISABLE_FORMAT_STRING_CHECKS :=true"
然后就好了，感谢国外大神。
