===stringstream et __android_log_print===

Avec une adaptation pour les cas non Android.

<code cpp>
#ifdef __ANDROID__

#include <android/log.h>
#include <sstream>

class MyStream {
 private:
  std::stringstream m_ss;
  int m_logLevel;

 public:
  MyStream(int Xi_logLevel) { m_logLevel = Xi_logLevel; };
  ~MyStream() {
    __android_log_print(m_logLevel, LOG_TAG, "%s", m_ss.str().c_str());
  }

  template <typename T>
  MyStream& operator<<(T&& Xi_val) {
    m_ss << std::forward<T>(Xi_val);
    return *this;
  }
};

#define MY_LOG(LOG_LEVEL) MyStream(ANDROID_LOG_##LOG_LEVEL)

#else

#include <iostream>

enum LogPriority {
  LOG_UNKNOWN = 0,
  LOG_DEFAULT,
  LOG_VERBOSE,
  LOG_DEBUG,
  LOG_INFO,
  LOG_WARN,
  LOG_ERROR,
  LOG_FATAL,
  LOG_SILENT
};

#define MY_LOG(LOG_LEVEL) (LOG_##LOG_LEVEL <= LOG_INFO ? std::cout : std::cerr)

#endif
