If you schedule a alarm with the same PendingIntent as before, the alarm you set before is updated and not a new one is set. Only one alarm is firing because your PendingIntent didn't change when you use it the second time, only the extras change (according to this question's answer this isn't considered a change).
To not update the old alarm but set a new one, you have to use a different request-code (the second parameter in getBroadcast() - currently you use 0 for both alarms).
Just use the id you already have as parameter in your section-constructor as request-code.

How to programatically set the reminder to a specific date

Here i have a code to set the date and time by the user.When the time arrives the notification will pop up.
The problem is that the user have to set the time manually.I want to set it programatically to a specific date, lets say 23 January 2016.So that the user have to just click the set button and forget about other things.

How could i do this?please help.Thanks.

This code will set the alarm to 23 January, 2016, 18:05:00. So you don't need TimePicker and DatePicker. See doc here: Calendar
Calendar cal = Calendar.getInstance();
cal.set(2016, 0, 23, 18, 5, 0);
setAlarm(cal);

here is my contribution what i did i haven't tested this but the concept is correct just try it out ...
Calendar calendar = Calendar.getInstance();
calendar.set(2016,MonthSelect("May"),DaySelect("Monday"));
if (SDK_INT < Build.VERSION_CODES.KITKAT) {
alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);
}else if (Build.VERSION_CODES.KITKAT <= SDK_INT && SDK_INT < Build.VERSION_CODES.M) {
alarmMgr.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);
}
else if (SDK_INT >= Build.VERSION_CODES.M) {
alarmMgr.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);
}
.......... then the other functions called..
private int MonthSelect(String mMonth){
if(mMonth=="January"){
return 0;
}else if(mMonth.equalsIgnoreCase("February")){
return 1;
}else if(mMonth.equalsIgnoreCase("March")){
return 2;
}else if(mMonth.equalsIgnoreCase("April")){
return 3;
}else if(mMonth.equalsIgnoreCase("May")){
return 4;
}else if(mMonth.equalsIgnoreCase("June")){
return 5;
}else if(mMonth.equalsIgnoreCase("July")){
return 6;
}else if(mMonth.equalsIgnoreCase("August")){
return 7;
}else if(mMonth.equalsIgnoreCase("September")){
return 8;
}else if(mMonth.equalsIgnoreCase("October")){
return 9;
}else if(mMonth.equalsIgnoreCase("Novermber")){
return 10;
}else {
return 11;
}
}
private int DaySelect(String mDay){
if(mDay.equalsIgnoreCase("Monday")){
return Calendar.MONDAY;
}else if (mDay.equalsIgnoreCase("Tuesday")){
return Calendar.TUESDAY;
}else if (mDay.equalsIgnoreCase("Wednesday")){
return Calendar.WEDNESDAY;
}else if (mDay.equalsIgnoreCase("Thursday")){
return Calendar.THURSDAY;
}else if (mDay.equalsIgnoreCase("Friday")){
return Calendar.FRIDAY;
}else if (mDay.equalsIgnoreCase("Saturday")){
return Calendar.SATURDAY;
}else{
return Calendar.SUNDAY;

Problem is that when I pick time when notification has to come up I press my button to save and then notification comes up immediately it ignores my timePicker and datePicker. What is the peoblem?

This is my solution for launch a notification on android :
public class MyNotification {
private NotificationManager nm;
private Notification nf;
private int notification_id;
public MyNotification(Context context, Class<?> cls, int icon, CharSequence tickerText, CharSequence title, CharSequence text, int notification_id) {
nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
nm.cancelAll();
Intent activity = new Intent(context, cls);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, activity, 0);
Notification.Builder builder = new Notification.Builder(context);
builder.setContentIntent(contentIntent); //-> Activity open after click
builder.setAutoCancel(true);
builder.setSmallIcon(icon);
builder.setWhen(System.currentTimeMillis());
builder.setTicker(tickerText);
builder.setContentTitle(title);
builder.setContentText(text);
//builder.setSound(Uri.parse("android.resource://"+this.getPackageName()+R.raw.good)); //-> Song
//builder.setContent(new RemoteViews(getPackageName(), R.layout.note)); //-> Layout
//builder.setVibrate(new long[]{0, 100, 25, 100}); // -> Vibration
Notification nf = builder.getNotification();
this.nf = nf;
this.notification_id = notification_id;
}
public void show() {
this.nm.notify(notification_id, nf);
}
}
I hope i have helped you!

Develop Alarm Application

I'd like develop an Alarm Application.
The application should work like this:
launch it
the activity show me the time
I can set the alarm
I can close the application
when the alarm time comes , it starts an activity (even if the device is locked)
I have tried to adapt this sample https://github.com/commonsguy/cwac-wakeful but I cannot launch an activity when the alarm time comes.
I use this code to setup the alarm (for test I have inserted this code on an onCreate method of activity):
Intent intent = new Intent(this, OnAlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 10);
AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, cal.getTimeInMillis(),
pendingIntent);
this is the OnAlarmReceiver class:
public class OnAlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.i(ClockActivity.LOG_TAG, "OnAlarmReceiver::onReceive");
WakefulIntentService.sendWakefulWork(context, AlarmService.class);
}
}
this is the service class:
public class AlarmService extends WakefulIntentService {
public AlarmService(String name) {
super(name);
}
#Override
protected void doWakefulWork(Intent intent) {
Log.i(ClockActivity.LOG_TAG, "AlarmService::doWakefulWork");
Intent newIntent = new Intent(getApplicationContext(), ClockActivity.class);
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
newIntent.setAction(ClockActivity.ALARM_ACTION);
getApplicationContext().startActivity(newIntent);
}
}
this is the portion of Manifest where are setup the service and the receiver:
<receiver android:name=".OnAlarmReceiver"></receiver>
<service android:name=".AlarmService"></service>
the doWakefulWork method is never called!

I have made this application:
AlarmActivity.java
package com.foo;
import pack.breceiver.MyBroadcastReceiver;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
import android.app.Activity;
import android.os.Bundle;
public class AlarmActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void startAlert(View view) {
EditText text = (EditText) findViewById(R.id.time);
int i = Integer.parseInt(text.getText().toString());
Intent intent = new Intent(this, MyBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this.getApplicationContext(), 234324243, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
+ (i * 1000), pendingIntent);
Toast.makeText(this, "Alarm set in " + i + " seconds",
Toast.LENGTH_LONG).show();
}
}
MyBroadcastReceiver.java
package pack.breceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Vibrator;
import android.widget.Toast;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Don't panik but your time is up!!!!",
Toast.LENGTH_LONG).show();
/*// Vibrate the mobile phone
Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(2000); */
}
}

check this out : http://blog.nelsondev.net/?p=124
using"alarmmanager"
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
AlarmCal.getTimeInMillis(), AlarmManager.INTERVAL_FIFTEEN_MINUTES,
pendingAlarmIntent);

I had a similar problem and I resolved removing the receiver from manifest and set in my code registering him with registerReceiver.

Do you get an instantiation exception maybe ?
You should have a public no arg constructor in your service :
public class AlarmService extends WakefulIntentService {
public AlarmService() {
super("AlarmService");
}
// etc
}
