How to run program in background in android?
<p>I have this code:</p>

<pre><code>package com.powergroupbd.timer;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class TimerActivity extends Activity implements OnClickListener {
    /** Called when the activity is first created. */

    EditText minute, seconds;
    Button fire;
    String min, sec;
    TextView Remain;
    MyCount timercount;
    Intent serviceIntent;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        initializer();
        fire.setOnClickListener(this);
    }

    private void initializer() {

        minute = (EditText) findViewById(R.id.etMinute);
        seconds = (EditText) findViewById(R.id.etSeconds);
        fire = (Button) findViewById(R.id.bFireTimer);
        Remain = (TextView) findViewById(R.id.tvRemain);
        serviceIntent = new Intent(TimerActivity.this, MyService.class);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {

        case R.id.bFireTimer:

            min = minute.getText().toString();
            sec = seconds.getText().toString();
            int MIN = Integer.parseInt(min);
            int SEC = Integer.parseInt(sec);
            long TIME = (MIN * 60) + SEC;
            timercount = new MyCount(TIME * 1000, 1000);
            timercount.start();

            startService(serviceIntent);

            break;
        }

    }

    public class MyCount extends CountDownTimer {

        public MyCount(long millisInFuture, long countDownInterval) {
            super(millisInFuture, countDownInterval);
        }

        @Override
        public void onFinish() {
            // some script here

            Remain.setText("0:0");
        }

        @Override
        public void onTick(long millisUntilFinished) {

            // some script here
            int remseconds = (int) millisUntilFinished / 1000;
            int remminuts = remseconds / 60;
            remseconds = remseconds % 60;
            remminuts = remminuts % 60;
            Remain.setText(String.format("%d : %02d", remminuts, remseconds));

            // Remain.setText(""+millisUntilFinished);

        }
    }

}

<p>I am putting some numeric value in an edittext and do countdown from that value to zero. But when I restart this app it starts from the begining and have to put those values again. But I want to do that countdown in background when I am not in that application. I used service here and My service class code is here:</p>

<pre><code>package com.powergroupbd.timer;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;

public class MyService extends Service {



    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }


    @Override
    public void onStart(Intent intent, int startId) {
        // TODO Auto-generated method stub
        super.onStart(intent, startId);
    }

    @Override
    public void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
    }

}
</code></pre>

<p>But nothing heppens, what to do now?</p>
