Here is the code below .Use it in your activities it works fine.

public class MainActivity extends AppCompatActivity {

    TextView textview;
    final static long INTERVAL = 1000;
    final static long TIMEOUT = 11000;
    static long millisecondsleft;
    boolean isPause =false;

    CountDownTimer countDownTimer;
    CountDownTimer countDownTimeronResume;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textview=findViewById(R.id.textviewcheck);
 }

    @Override
    protected void onResume() {
        super.onResume();

       if(isPause == false) {
           countDownTimer = new CountDownTimer(TIMEOUT, INTERVAL) {
               @Override
               public void onTick(long millisUntilFinished) {
                   millisecondsleft = millisUntilFinished;
                   textview.setText(":" + String.format("%02d", millisUntilFinished / 1000));
               }

               @Override
               public void onFinish() {

                   textview.setText("DONE!");
               }
           }.start();

       } else{
                     countDownTimeronResume = new CountDownTimer(millisecondsleft, INTERVAL) {
                       @Override
                       public void onTick(long millisUntilFinished) {
                           Toast.makeText(MainActivity.this, "ONPAUSED", Toast.LENGTH_SHORT).show();
                           millisecondsleft = millisUntilFinished;
                           textview.setText(":" + String.format("%02d", millisUntilFinished / 1000));
                       }

                       @Override
                       public void onFinish() {
                           textview.setText("DONE!");

                       }
                   }.start();
         }


    }

    @Override
    protected void onPause() {
        super.onPause();

        if(countDownTimer!=null){
            countDownTimer.cancel();
            isPause = true;
        }
       if(countDownTimeronResume!=null){
            countDownTimeronResume.cancel();
       }
    }
}
