adding a alarm cancel button in the notification

I have been working on setting alarms using AlarmManager.
Set:
Intent myIntent = new Intent(getApplicationContext(), SessionReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
getApplicationContext(), reqCode, myIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, now.getTimeInMillis(), pendingIntent);
cancel:
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent myIntent = new Intent(getApplicationContext(), SessionReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
getApplicationContext(), reqCode, myIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.cancel(pendingIntent);
in my alarm receiver I want to be able to receive a notification which has a button that allows me to call cancelAlarm(). however I don't see the best approach to this and looking for the best and most reliable way of doing this.
I get the requestCodes so I am able tell which alarm to cancel

Android AlarmManager not cancelling alarms correctly

I'm working on an app which will allow users to set multiple notifications, and cancel any notification they choose.
The problem I have is that when I cancel a pending intent using the AlarmManager it is cancelling all alarms. Each of my pending intents has it's own unique request code.
For instance I would call this to create the alarm and then delete:
setAlarm(5062, 1453269670) // Set alarm 1
setAlarm(5063, 1453774418) // Set alarm 2
cancelAlarm(5062) // Cancel alarm 1
cancelAlarm(5063) // Cancel alarm 2
Setting mutiple alarms always works, I can set as many as I like and they all produce the notification. However if I was to cancel alarm 1, it also cancels alarm 2.
I know that the pending intent has to be the same when setting and cancelling, and each pending intent has it's own unique request code, so I don't know why it's not working. I've spent many hours googling, but none of the suggested answers have helped me.
void setAlarm(int request_code, long alarm_time) {
Intent intent = new Intent(context, NotificationReceiver.class);
intent.putExtra("request_code", request_code);
PendingIntent pendingIntent = PendingIntent.getService(context, request_code, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, alarm_time, pendingIntent);
}
void cancelAlarm(int request_code) {
Intent intent = new Intent(context, NotificationReceiver.class);
intent.putExtra("request_code", request_code);
PendingIntent pendingIntent = PendingIntent.getService(context, request_code, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
pendingIntent.cancel();
alarmManager.cancel(pendingIntent);
}

The answer is simple
Intent firstIntent = new Intent(this, Receiver.class);
intent.setAction("action 1");
intent.putExtra("extra", "extra1");
firstPendingIntent = PendingIntent.getBroadcast(this, 0, firstIntent, 0);
Intent secondIntent = new Intent(this, Receiver.class);
intent.setAction("action 2");
intent.putExtra("extra", "extra2");
secondPendingIntent = PendingIntent.getBroadcast(this, 0, secondIntent, 0);
if you compare two PendingIntents created in ABOVE code they are NOT EQUAL
But in code BELOW:
Intent firstIntent = new Intent(this, Receiver.class);
intent.setAction("action 1");
intent.putExtra("extra", "extra1");
firstPendingIntent = PendingIntent.getBroadcast(this, 0, firstIntent, 0);
Intent secondIntent = new Intent(this, Receiver.class);
intent.setAction("action 1");
intent.putExtra("extra", "extra2");
secondPendingIntent = PendingIntent.getBroadcast(this, 0, secondIntent, 0);
if you compare two PendingIntents they gonna be EQUAL, so doesn't matter what you pass in putExtra method

AlarmManager doesn't seem to be working

I'm trying to schedule a method to be called using AlarmManager, but it doesn't seem to be working. I've looked at other examples and theirs isn't working for me. So I'm thinking it's something from my code. Here's the AlarmManager code:
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent = new Intent(SplashScreenActivity.this, KinectReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(SplashScreenActivity.this, 0, intent, 0);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 2);
calendar.set(Calendar.MINUTE, 25);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
And my broadcast receiver:
public class KinectReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Done", Toast.LENGTH_LONG).show();
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_stat_notify)
.setContentTitle("Kinect")
.setColor(ContextCompat.getColor(context, R.color.colorAccent))
.setWhen(System.currentTimeMillis())
.setContentText("Your Kinects and Likes have been refilled. Now get to swiping")
.setAutoCancel(true)
.setSound(uri)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText("Your Kinects and Likes have been refilled. Now get to swiping"))
.setVibrate(new long[] { 100, 500, 100, 500, 100 });
Intent targetIntent = new Intent(context, MainActivity.class);
targetIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
targetIntent.putExtra("action", "main");
targetIntent.putExtra("id", "");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);
builder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
}
}
Neither the Toast nor the Notification show.
The AlarmManager code is in the first thing that runs in my launcher activity, in case that helps. Thanks

Please register ur receiver in manifeast file like this
In application tag
<receiver
android:name=".KinectReceiver">

Second question is how to cancel alarm
Here is ur answer
Intent myIntent = new Intent(MainActivity.this, AlarmActivity.class);
pendingIntent = PendingIntent.getActivity(CellManageAddShowActivity.this,
id, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
pendingIntent.cancel();
alarmManager.cancel(pendingIntent);
The main thing that you will need is:
1).Create pending intent with the same id and appropriate intent FLAG.
2).Cancel that pending intent.
3).Cancel the alarm using alarm manager.

Stopping alarm and alarm ringtone together

I am developing an alarm app.
When it fires an alarm it throws notification with a disable button.
So when i click on the disable button it should stop the alarm ringtone and the alarm also.
so when i click on disable button it call the below method.
It stops the alarm.
But i want to know will this ringtone alive for next date with same time or it will remove the alarm forgood?
public void dismissRingtone() {
// stop the alarm rigntone
Intent i = new Intent(this, RingtonePlayingService.class);
stopService(i);
// also dismiss the alarm to ring again or trigger again
AlarmManager aManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
aManager.cancel(pendingIntent);
// Canceling the current notification
NotificationManager notificationManager =
(NotificationManager)getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
notificationManager.cancel(321);
}

Try, it will cancel future alarms.
Intent intentAlarm = new Intent(this, AlarmReceiver.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
// Set the alarm for a particular time.
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
try {
pendingIntent.cancel();
alarmManager.cancel(pendingIntent);
} catch (Exception e) {
e.printStackTrace();
}

How to create a custom notification in android

I would like to create a custom notification service in my app.
I wouldn't use the google service (google cloud messaging).
Is there a way to create a daemon that check every X seconds a particular condition on my app db and show a notification?
Thank you,
edit
I call this method in MainActivity's oncreate(). I get the times from my db
private void restartNotify() {
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
intent, PendingIntent.FLAG_CANCEL_CURRENT);
am.cancel(pendingIntent);
ArrayList<String> item = new ArrayList<String>();
item = GetLists.GetTimesListForNotification(this);
for (int i = 0; i < item.size(); ++i) {
String time = item.get(i);
int Position = time.indexOf(":");
int hour = Integer.parseInt(time.substring(0, Position));
int min = Integer.parseInt(time.substring(Position + 1));
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, hour);
cal.set(Calendar.MINUTE, min);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
am.set(AlarmManager.RTC, cal.getTimeInMillis(),
pendingIntent);
}
And this is my broadcast receiver
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManager mManager;
mManager = (NotificationManager) context.getApplicationContext()
.getSystemService(
context.getApplicationContext().NOTIFICATION_SERVICE);
Intent intent1 = new Intent(context.getApplicationContext(),
MainActivity.class);
Notification notification = new Notification(R.drawable.ic_launcher,
"New message to read", System.currentTimeMillis());
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP
| Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
context.getApplicationContext(), 0, intent1,
PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(context.getApplicationContext(),
"notification are work", "it's work",
pendingNotificationIntent);
mManager.notify(0, notification);
}
}

You can use AlarmManager + BroadcastReceiver like so:
private void setRecurringAlarm(Context context) {
Intent downloader = new Intent(this, MyStartServiceReceiver.class);
downloader.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, downloader, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 6000, 10000, pendingIntent);
}
BroadcastReceiver class:
public class MyStartServiceReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//do the stuff...
}
}
And don't forget to register receiver in your manifest:
<receiver android:name=".MyStartServiceReceiver"
android:enabled="true"/>

You have to use Alarm Manager to schedule code for execution every specific period. take a look here:
