Problems To Cancel A CountDownTimer Android Java

android, back, countdowntimer, java

Solution

Create a global object of `CountDownTimer` eg.

On top of the main_activity class set: `CountDownTimer timer;` after that do the things below.

timer = new CountDownTimer(11000, 1000) 
        {
           public void onTick(long millisUntilFinished) 
           {
             global.toast.setText("No Internet Connection!" + "\n" + "Automatic Refresh In: " + millisUntilFinished / 1000); //set text for toast
             global.toast.show(); //show toast
           }

           public void onFinish() 
           {
              if (network_connected == false) 
              {
                 global.cancel_toast(0); //stop all toasts
                 finish(); //quit activity
                 startActivity(new Intent(main_activity.this, main_activity.class)); //start activity
              }
              else 
              {
              }
          }
      }.start(); //start the countdowntimer
}

and on `onBackPressed` call `timer.cancel();` like

@Override
public void onBackPressed() 
{
  if (page_number > global.page_number_min) 
  { //does not matter
    page_number--; //does not matter
    global.cancel_toast(0); //stop all toasts
    network_connected = true;
    finish();
  }
  else
  {
    global.cancel_toast(0);
    network_connected = true;
    finish(); //quit activity
    super.onBackPressed(); //quit application
  }

 timer.cancel();
}

Problem

When I close my app by pressing the BACK button (onBackPressed() called), the `CountDownTimer` doesn't stop, until it is done with counting. How can I put the `CountDownTimer` cancel(); in my `onBackPressed()`? Because, when I quit my application (shown below with descriptions) I don't want counter toasts on my screen anymore. On top of my code: ``` boolean network_connected = false; ``` What's in my `onCreate()`: ``` if (check_network.isInternetAvailable(this)) { network_connected = true; new connect_task_main().execute(""); } else { network_connected = false; } if (network_connected == false) { new CountDownTimer(11000, 1000) { public void onTick(long millisUntilFinished) { global.toast.setText("No Internet Connection!" + "\n" + "Automatic Refresh In: " + millisUntilFinished / 1000); //set text for toast global.toast.show(); //show toast } public void onFinish() { if (network_connected == false) { global.cancel_toast(0); //stop all toasts finish(); //quit activity startActivity(new Intent(main_activity.this, main_activity.class)); //start activity } else { } } }.start(); //start the countdowntimer } else { network_connected = true; } ``` `onBackPressed()` method ``` @Override public void onBackPressed() { if (page_number > global.page_number_min) { //does not matter page_number--; //does not matter global.cancel_toast(0); //stop all toasts network_connected = true; finish(); } else { global.cancel_toast(0); network_connected = true; finish(); //quit activity super.onBackPressed(); //quit application } } ``` Thanks.
