      The timer is essential for the application to function Rescue PHOTO. The timer starts the camera, connects to the FTP server, copies the file, disconnects the server, and waits for the next picture.
      Minimum procedure for working with a timer:
      //==== Timer operation ===================
       timer = new Timer();
       mTimerTask = new MyTimerTask();
       // Timer start
       timer.schedule(mTimerTask, 1000, 1000); // We perform the action with a delay of 1 second
           // delay - how much to start
           // period - how many times to repeat
      Nothing prevents you from using multiple timers in the application.
      In Android, many important actions are performed using callbacks. For example, when using a camera. They can be used when various events occur.
      When a photo is copied to the FTP server, the end of copying also triggers an event. This can be handled.
      However, if you are using mobile internet, you need to take into account that traffic is limited and you cannot upload photos to the server too often.
      And here it is already necessary to check two conditions. If the photo is uploaded to the FTP server, you need to wait until the next operation of the camera starts. If the photo is taken and it takes a very long time to upload to the FTP server, then the timer should be increased. But here you need to use a second timer, so that the waiting period for the upload of a photo does not become eternal.
      TimerTask mTimerTask; - Announce timer
      Stop timer
      timer = null;
      Log.i(TAG, "==== Timer STOPED ===="); // Writing a message to LOG
