title: A service in android which send SMS at regular interval
body: <p>I want to make a service in android which run in background always and start as soon as I boot my phone and send message at a regular interval.I have writen my code as below</p>
  
  <p>MainActivity.class</p>
  
  <pre><code> package test.sai;
  
  
  
   public class MainActivity extends Activity {
  
  Timer t;
  
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
  
  
      alrm();
      Log.e("msg", "in main");
  
  
  }
  
  
  
  
  
  
  public  void alrm() {
      Intent myAlarm = new Intent(getApplicationContext(), AlarmReceiver.class);
      Log.e("msg", "in alrm");
      //myAlarm.putExtra("project_id", project_id); //Put Extra if needed
      PendingIntent recurringAlarm =      v     PendingIntent.getBroadcast(getApplicationContext(), 0, myAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
      AlarmManager alarms = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
      Calendar updateTime = Calendar.getInstance();
      Log.e("msg", "in alrm1");
      //updateTime.setWhatever(0);
      alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP,        updateTime.getTimeInMillis(), AlarmManager.INTERVAL_FIFTEEN_MINUTES, recurringAlarm); //you can modify the interval of course
  
  }
  
  
  
  
  }
  </code></pre>
  
  <p>This class is calling AlarmReceiver.class</p>
  
  <pre><code>package test.sai;
  
  
  
   public class AlarmReceiver extends BroadcastReceiver 
   {  
  GPSTracker gps;
  
  @Override
  public void onReceive(Context context, Intent intent) 
  {
      gps = new GPSTracker(context);
  
      if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {  
             Intent pushIntent = new Intent(context,MainActivity.class); 
             pushIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
             context.startActivity(pushIntent);
  
  
  
             Log.e("pro", "alrmmanager");
             }
  
      Intent myService = new Intent(context, FirstService.class);
      myService.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
      context.startService(myService);
      Log.e("msg", "in alrmmanager1");
  
  
  
  
  
  }
  
   }  
  </code></pre>
  
  <p>and finally AlarmReceiver is calling the service class</p>
  
  <pre><code> package test.sai;
  
  
  
   public class FirstService extends Service{
  
  Timer t;
  int time = 0;
  
  @Override
  public IBinder onBind(Intent arg0) {
  
  
      // TODO Auto-generated method stub
      return null;
  }
  @Override
  public void onStart(Intent intent, int startId) {
  
  
      Log.e("time", time++ +"");
      Toast.makeText(this, time+1+"", 500).show();
  
  
  
  
  
  }
  @Override
  public void onDestroy() {
      // TODO Auto-generated method stub
      super.onDestroy();
  
  }
  </code></pre>
  
  <p>}</p>
