Answer 1

You are gonna need a variable that keeps track on the time that has passed since the Chronometer was started:

long timeWhenStopped = 0; 

Update the value of the variable when you stop the chronometer like this:

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

We will also use this variable to adjust the chronometer before starting it:

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

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

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