    <p>I am developing an application where i need to send an sms to a particular phone number. I can send the sms using following code.</p> <pre><code>try { SmsManager smsManager = SmsManager.getDefault(); smsManager.sendTextMessage(phoneNo, null, sms, null, null); Toast.makeText(getApplicationContext(), "SMS Sent!", Toast.LENGTH_LONG).show(); } catch (Exception e) { Toast.makeText(getApplicationContext(), "SMS faild, please try again later!", Toast.LENGTH_LONG).show(); e.printStackTrace(); } </code></pre> <p>Now what i want is the sms should go automatically. The time, at which the message should go automatically, is stored in MySQL database.So i need the code that will keep on checking when that time comes and then send the message to that number automatically. Its a kind of reminder thing. The user will keep a reminder in application eg.; i need to get a message after 1 hour. So after 1 hour the message should come. PLz help??</p> <p>Finally i got it.</p> <pre><code>/** Code For reminder is here */ int time=Integer.parseInt(answer); int num = (int)System.currentTimeMillis(); Intent intent = new Intent(getApplication(), MyBroadcastReceiver.class); intent.putExtra("phoneNo",phoneNo); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.add(Calendar.MINUTE, time); PendingIntent pendingIntent = PendingIntent.getBroadcast( getApplicationContext(), num, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + calendar.getTimeInMillis() , pendingIntent); Toast.makeText(getApplication(), "Alarm set in " + time + " minutes", Toast.LENGTH_SHORT).show(); /** Code for reminder is over */ </code></pre> <p>And my reciever code is </p> <pre><code> public void onReceive(Context context, Intent intent) { String sms= "Your turn is about to come. Please be ready. Thank You"; String phoneNo; Bundle extrasBundle = intent.getExtras(); phoneNo=extrasBundle.getString("phoneNo"); try { SmsManager smsManager = SmsManager.getDefault(); smsManager.sendTextMessage(phoneNo, null, sms, null, null); Toast.makeText(context, "SMS Sent to " + phoneNo,Toast.LENGTH_LONG).show(); } catch (Exception e) { Toast.makeText(context,"SMS faild, please try again later!",Toast.LENGTH_LONG).show(); e.printStackTrace(); } </code></pre> <p>}</p> <p>Just in case someone might need this... Thanku</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
