i am facing issue in chronometer if i pause chronometer it not starting where it is stopped

Question

I am facing issue in chronometer if I pause chronometer it not starting where it is stopped. so I need to start where it is stopped. In onlocation change method if meter less then 5 meters time will start if greater then 5 meters the time will stop but it is not starting where it is stopped

public class MainActivity{

@Override
public void onLocationChanged(@NonNull Location location) {

        if (mPresenter.getLocalSTATUS() != null && mPresenter.getLocalSTATUS().equalsIgnoreCase(LOCAL_CONTINUE_RIDE))
                    {
                        if(mPresenter.getLocalSTATUS().equalsIgnoreCase(LOCAL_CONTINUE_RIDE))
                        {

                            if (results[0] < 5.09) {
                                cmTimer.start();

                            }
                            else {
                                pauseOffset = SystemClock.elapsedRealtime();
                                cmTimer.stop();

                            }


                        }
                    }

        }

        public void DonePickUpUI_OnClick() {

You are gonna need a variable that keeps track on the time.

long timeWhenStopped = 0;

Update the value of the variable when you stop the chronometer

timeWhenStopped = cmTimer.getBase() - SystemClock.elapsedRealtime();
cmTimer.stop();

Use this variable to adjust the chronometer before starting it

cmTimer.setBase(SystemClock.elapsedRealtime() + timeWhenStopped);
cmTimer.start();

And finally if you have a way to reset your chronometer then you should remember to also reset the timeWhenStopped variable.

cmTimer.setBase(SystemClock.elapsedRealtime());
timeWhenStopped = 0;

i am facing issue in chronometer if i pause chronometer it not starting where it is stopped
