Answer 1

A nice and simple way to create a Pause/Resume for your CountDownTimer is to create a separate method for your timer start, pause and resume as follows:

public void timerStart(long timeLengthMilli) {
        timer = new CountDownTimer(timeLengthMilli, 1000) {

            @Override
            public void onTick(long milliTillFinish) {
                milliLeft=milliTillFinish;
                min = (milliTillFinish/(1000*60));
                sec = ((milliTillFinish/1000)-min*60);
                clock.setText(Long.toString(min)+":"+Long.toString(sec));
                Log.i("Tick", "Tock");
            }

The timerStart has a long parameter as it will be reused by the resume() method below. Remember to store your milliTillFinished (above as milliLeft) so that you may send it through in your resume() method. Pause and resume methods below respectively:

public void timerPause() {
        timer.cancel();
    }

    private void timerResume() {
        Log.i("min", Long.toString(min));
        Log.i("Sec", Long.toString(sec));
        timerStart(milliLeft);
    }

Here is the code for the button FYI:

startPause.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(startPause.getText().equals("Start")){
                    Log.i("Started", startPause.getText().toString());
                    startPause.setText("Pause");
                    timerStart(15*1000);
                } else if (startPause.getText().equals("Pause")){
                    Log.i("Paused", startPause.getText().toString());
                    startPause.setText("Resume");
                    timerPause();
                } else if (startPause.getText().equals("Resume")){
                    startPause.setText("Pause");
                    timerResume();
                }
