Android ndk std::to_string support

You can try LOCAL_CFLAGS := -std=c++11, but note that not all C++11 APIs are available with the NDK’s gnustl. Full C++14 support is available with libc++ (APP_STL := c++_shared).

The alternative is to implement it yourself.

#include <string>
#include <sstream>

template <typename T>
std::string to_string(T value)
{
    std::ostringstream os ;
    os << value ;
    return os.str() ;
}

int main()
{
    std::string perfect = to_string(5) ;
}
