How to change one counter every minute (android development)

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver {

	
	private int i = 0;

	@Override
	public void onReceive(Context context, Intent intent) {
		PowerManager pm = (PowerManager) context
				.getSystemService(Context.POWER_SERVICE);
		PowerManager.WakeLock wl = pm.newWakeLock(
				PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
		
		wl.acquire();

		
		Bundle extras = intent.getExtras();

		StringBuilder msgStr = new StringBuilder();
		if (extras != null && extras.getBoolean(ONE_TIME, Boolean.FALSE)) {
			msgStr.append("One time Timer : ");
		}

		Format formatter = new SimpleDateFormat("hh:mm:ss a");
		msgStr.append(formatter.format(new Date()));
		Toast.makeText(context, msgStr, Toast.LENGTH_LONG).show();

		
		wl.release();
	}

	public void SetAlarm(Context context) {
		AlarmManager am = (AlarmManager) context
				.getSystemService(Context.ALARM_SERVICE);
		Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
		intent.putExtra(ONE_TIME, Boolean.FALSE);
		PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
		am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
				60*1000, pi);

	}

as you see I want to increase i;
