  <pre><code>public class MainActivity extends Activity {
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
              @Override
              public void onClick(View v) {
                  setalarm();
              }
  
  
          });
      }
  
      private void setalarm() {
  
          Calendar cal=Calendar.getInstance();
          // cal.set(Calendar.MONTH,6);
          // cal.set(Calendar.YEAR,2013);
          // cal.set(Calendar.DAY_OF_MONTH,12);
          cal.set(Calendar.HOUR_OF_DAY,18);
          cal.set(Calendar.MINUTE,32);
          Intent intent = new Intent(this, Mote.class);
          PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 1253, intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);
  
          AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
  
          alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),pendingIntent );
          alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
          Toast.makeText(this, "Alarm SET.", Toast.LENGTH_LONG).show();
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          getMenuInflater().inflate(R.menu.activity_main, menu);
          return true;
      }
  }
  </code></pre>
  
  <p>Mote.java:</p>
  
  <pre><code>public class Mote  extends BroadcastReceiver{
  
      public void onReceive(Context context, Intent intent) {
          Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
          int icon = R.drawable.ic_launcher;
          CharSequence tickerText = "Hello you have to take medicine I am Nitin Sharma";
          long when = System.currentTimeMillis();
  
          CharSequence contentTitle = "My notification";
          CharSequence contentText = "Hello World!";
  
          final int NOTIF_ID = 1234;
          NotificationManager notofManager = (NotificationManager)context. getSystemService(Context.NOTIFICATION_SERVICE);
          Intent notificationIntent = new Intent(context, Alset.class);
          PendingIntent contentIntent = PendingIntent.getActivity(context,0, notificationIntent, 0);
          Notification notification = new Notification(icon, tickerText,when );
          notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
          notification.flags = Notification.FLAG_INSISTENT;
          notification.defaults |= Notification.DEFAULT_SOUND;
          notofManager.notify(NOTIF_ID,notification);
  
          Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
  
          Intent i = new Intent(context,Alset.class);
          i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          context.startActivity(i);
  </code></pre>
  
  <p>Alset.java:</p>
  
  <pre><code>public class Alset extends Activity{
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          // TODO Auto-generated method stub
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activitystop); 
          Log.e("IM here ","Im here");
  
          findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
  
              @Override
              public void onClick(View v) {
                  Toast.makeText(Alset.this, "Stop the alrm now", Toast.LENGTH_LONG).show();
              }
          });
      }   
  }
  </code></pre>
  
  <p>Once the alarm starts I will get the callback in the receiver's <code>OnReceive()</code> method. From there I'm going to the activity Alset where I kept a stop button. How do I to stop the alarm from here?</p>
  
  <p>NOTE: - I'm hardcoding the time to set the alarm.</p>
