import android.widget.ListView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Toast;


public class Notify extends Activity {
    Button btn;

    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.nit);
        Calendar cal=Calendar.getInstance();
        cal.set(Calendar.MONTH,6);
        cal.set(Calendar.YEAR,2011);
        cal.set(Calendar.DAY_OF_MONTH,29);
        cal.set(Calendar.HOUR_OF_DAY,17);

        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);

        CharSequence contentText = "Hello World!";


        //notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        final int NOTIF_ID = 1234;
        NotificationManager notofManager = (NotificationManager)context. getSystemService(Context.NOTIFICATION_SERVICE);

        //notification.setLatestEventInfo(context, "Context Title", "Context text", contentIntent);

How to get all the remainder details associated with the specific application? That means the alarm id, text, title something like that. — Karthick, Sep 27 '13 at 04:07
For that you have to make a separate database table for storing that. — Nitin, Sep 27 '13 at 07:28
Is any other way to achieve that without using the database? — Karthick, Sep 27 '13 at 07:30
If I am using the above code for creating the alarm means, the device reboot removes all the reminder associated with the app. How can I restore all the 10 remainders after the device rebooted.? — Karthick, Sep 27 '13 at 07:32
Yes, But I am facing problem, how and where to set all the alarms? — Karthick, Sep 27 '13 at 13:24

I think you want to set the alarm for 26th June and not 26th July. If so then change cal.set(Calendar.MONTH,6); to cal.set(Calendar.MONTH,5); because the months are zero-based. if you intend the alarm to fire on 26th july then it is expected that the alarm will fire when the date-time is 26th July 2011, 17:30

1.add this in manifest file

 <receiver android:name=".MyAlarmReciever">
            <intent-filter>
                <action android:name="com.example.helloandroid.alarms" />
            </intent-filter>
        </receiver>

make a activity

     public class AlrmActivity extends BaseAcitivity {

        TimePicker myTimePicker;
        Button buttonstartSetDialog;
        TextView textAlarmPrompt;

        TimePickerDialog timePickerDialog;

        final static int RQS_1 = 1;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_alrm);

            textAlarmPrompt = (TextView)findViewById(R.id.alarmprompt);

            buttonstartSetDialog = (Button)findViewById(R.id.startSetDialog);
            buttonstartSetDialog.setOnClickListener(new View.OnClickListener(){

                @Override
                public void onClick(View v) {
                    textAlarmPrompt.setText("");
                    openTimePickerDialog(false);

                }});


        }

        private void openTimePickerDialog(boolean is24r){
            Calendar calendar = Calendar.getInstance();

            timePickerDialog = new TimePickerDialog(
                    AlrmActivity.this,
                    onTimeSetListener,
                    calendar.get(Calendar.HOUR_OF_DAY),
                    calendar.get(Calendar.MINUTE),
                    is24r);
            timePickerDialog.setTitle("Set Alarm Time");

            timePickerDialog.show();

        }
        TimePickerDialog.OnTimeSetListener onTimeSetListener
                = new TimePickerDialog.OnTimeSetListener(){

            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                Calendar calNow = Calendar.getInstance();
                Calendar calSet = (Calendar) calNow.clone();

                calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
                calSet.set(Calendar.MINUTE, minute);
                calSet.set(Calendar.SECOND, 0);
                calSet.set(Calendar.MILLISECOND, 0);

                if(calSet.compareTo(calNow) <= 0){
                    //Today Set time passed, count to tomorrow
                    calSet.add(Calendar.DATE, 1);
                }

                setAlarm(calSet);
            }};

        private void setAlarm(Calendar targetCal){

            textAlarmPrompt.setText(
                    "\n\n***\n"
                            + "Alarm is set@ " + targetCal.getTime() + "\n"
                            + "***\n");

            Intent intent = new Intent(getBaseContext(), MyAlarmReciever.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
            AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
            alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent);

        }

    }

3 . xml file include

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <TextView

            android:layout_height="wrap_content"
            android:text="hello" />
        <Button
            android:id="@+id/startSetDialog"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Set Target Time"/>
        <TextView

            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>

4 .make alarm manager class

    public class MyAlarmReciever extends BroadcastReceiver {

        Vibrator v;
        Context ct;
        String  title;


        @Override
        public void onReceive(Context context, Intent intent) {

            // TODO Auto-generated method stub

            Toast.makeText(context, "OnReceive alarm test", Toast.LENGTH_SHORT).show();

            v=(Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
            v.vibrate(3000);

            int badgeCount = 1;
           // ShortcutBadger.applyCount(context, badgeCount);

            ShortcutBadger.removeCount(context);

            Bundle bundle = intent.getExtras();

    //        }

        }


        public void Notification(Context context, String message) {
            // Set Notification Title
            String strtitle = "iPray  Prayer Reminder";
            // Open NotificationView Class on Notification Click

            PendingIntent pIntent = PendingIntent.getActivity(context, 0, intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);

    //        NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.drawable.app_icon, "Previous", pIntent).build();
            // Create Notification using NotificationCompat.Builder
            NotificationCompat.Builder builder = new NotificationCompat.Builder(
                    context)
                    // Set Icon
                    .setSmallIcon(R.drawable.app_icon)
                    // Set Ticker Message
                    .setTicker(message)
                    // Set Title

                    // Set Text
                    .setContentText(message)
                    // Add an Action Button below Notification
                    // Set PendingIntent into Notification
                    .setContentIntent(pIntent)
                    // Dismiss Notification
                    .setAutoCancel(true);

            // Create Notification Manager
            NotificationManager notificationmanager = (NotificationManager) context
                    .getSystemService(Context.NOTIFICATION_SERVICE);
            // Build Notification with Notification Manager
            notificationmanager.notify(38, builder.build());

        }

Have you set the receiver in your manifest file? Something like this

<receiver  android:process=":remote" android:name=".Mote"></receiver>

Yes, but `android:process=":remote"` is not 100% necessary. – Kevin Yuan Jun 29 '11 at 12:39
Yeah dude, android:process tag is only for running Services and Receivers in a separate process from your own app. – IgorGanapolsky Aug 21 '14 at 14:05
