Android ndk cannot locate symbol "atof" referenced by的解决方法

原因：android的stdlib.h中atof是内联的

解决方法：将所有的atof改成strtod

示例代码：

  char *strpi = "3.1415";

  double dpi;

  dpi = atof(strpi);     修改为： dpi = strtod(strpi, NULL);

参考自：http://stackoverflow.com/questions/14571399/Android-ndk-cant-find-atof-function

原文如下：

From stdlib.h in the Android source;

static __inline__ double atof(const char *nptr)
{
    return (strtod(nptr, NULL));
}

atof is in other words not a library function, it's an inline function that calls strtod.

If you need to call through loading a library, just use strtod instead.
