SetText method asks for a String parameter. Try this

tv.setText(String.valueOf(time));

move this line before creating the object of timer after setContentView(R.layout.main);

tv = (TextView) findViewById(R.id.tvDisplay);

and change

tv.setText(time);

to

tv.setText(String.valueOf(time));

coz setText() always takes String as a parameter u r passing an int thats why facing force close
