Android timer updating a textview (UI)

I'm using a timer to create a stop watch. The timer works by increasing a integer value. I want to then display this value in the activity by constantly updating a textview.

Here's my code from the service where I try and update the activity's textview: 

protected static void startTimer() {
    isTimerRunning = true; 
    timer.scheduleAtFixedRate(new TimerTask() {
        public void run() {
            elapsedTime += 1; //increase every sec
            StopWatch.time.setText(formatIntoHHMMSS(elapsedTime)); //this is the textview
        }
    }, 0, 1000);
}

I got some kind of error about updating the UI in the wrong thread.

How can I adapt my code to accomplish this task of constantly updating the textview?

I use this way:

String[] array = {"man", "for", "think"}; 
int j;

Then add more onCreate:

TextView t = findViewById(R.id.textView);

new CountDownTimer(5000,1000) {

    @Override
    public void onTick(long millisUntilFinished) {}

    @Override
    public void onFinish() {
        t.setText("I " + array[j] + " You");
        j++;
        if (j == array.length - 1) j = 0;
        start();
    }
}.start();
