jni 写日志，每隔一分钟写一个日志文件

// 全局变量用于存储日志文件的日期和路径
std::string currentLogFile;// 获取当前日期时间的函数
std::string getCurrentDateTime() {time_t now = time(0);struct tm *timeinfo = localtime(&now);char buffer[80];strftime(buffer, sizeof(buffer), "%Y_%m_%d_%H_%M_%S", timeinfo);return std::string(buffer);
}void writeLog(const std::string& message) {// 获取当前日期std::string currentDate = getCurrentDateTime().substr(0, 16);// 如果当前日期与日志文件日期不同，则创建新的日志文件if (currentLogFile != currentDate) {currentLogFile = currentDate;std::string logFilePath = "/storage/emulated/0/" + currentLogFile + ".log";currentLogFile = logFilePath;// 写入日志信息std::ofstream logFile(logFilePath, std::ios_base::app);logFile << "========== " << currentLogFile << " ==========\n";logFile.close();}// 写入日志信息std::ofstream logFile(currentLogFile, std::ios_base::app);logFile << message << std::endl;logFile.close();
