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.

Using repeating Notifications using AlarmManager

I'm trying to develop an app which requires scheduled notifications everyday at 7am, 11am and 7pm. And when user taps on the notification it takes the user to MainActivity.
I have a working code but it's showing random behavior. I have the following problems.
1) Every time I open MainActivity, it triggers the alarm manager and shows a notification even though it's only supposed to be triggered at 7am, 11am and 7pm.
2) Also, I think I'm somehow duplicating alarms every time I open the main activity. Everytime I setup the alarm, I cancel the pending intent and then setup again. Is this the correct way to do it?
Manifest.xml
<receiver android:name=".AlarmReceiver">
<intent-filter>
<action android:name="android.media.action.DISPLAY_NOTIFICATION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
MainActivity.java
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Calendar cal = Calendar.getInstance();
Calendar cal1 = Calendar.getInstance();
Calendar cal2 = Calendar.getInstance();
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, 0);
PendingIntent broadcast1 = PendingIntent.getBroadcast(this, 101, notificationIntent, 0);
PendingIntent broadcast2 = PendingIntent.getBroadcast(this, 102, notificationIntent, 0);
cal.set(Calendar.HOUR_OF_DAY, 7);
cal.set(Calendar.MINUTE, 0);
alarmManager.cancel(broadcast);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, broadcast);
cal1.set(Calendar.HOUR_OF_DAY, 11);
cal1.set(Calendar.MINUTE, 0);
alarmManager.cancel(broadcast1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, broadcast1);
cal2.set(Calendar.HOUR_OF_DAY, 19);
cal2.set(Calendar.MINUTE, 0);
alarmManager.cancel(broadcast2);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, broadcast2);
AlarmReceiver.java
#Override
public void onReceive(Context context, Intent intent) {
String Text = getText();

Android: How to create a reminder such as google keep reminder

I want to add a reminder to my android app such as Google Keep app reminder for notes, as you know in Gkeep you can set reminder for your notes by set date (Today,Tomorrow,Next same day or Pick a date from Calendar) and set time (Morning, Afternoon,Evening, Night or pick a time from Clock).
Any help?

I found my answer! and share it with you because i think its nothing to do with Mechanical Turk :)).
in MainActivity:
final AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
final Intent intentAlarm = new Intent(MainActivity.this, AlarmReceiver.class);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 22);
calendar.set(Calendar.HOUR, 5);
calendar.set(Calendar.AM_PM, Calendar.PM);
calendar.set(Calendar.MONTH, 0);
calendar.set(Calendar.DAY_OF_MONTH, 6);
calendar.set(Calendar.YEAR,2015);
long when = calendar.getTimeInMillis();
alarmManager.set(AlarmManager.RTC_WAKEUP,when, PendingIntent.getBroadcast(MainActivity.this,1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
and the AlarmReciver class :
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Calendar now = GregorianCalendar.getInstance();
Notification.Builder mBuilder =
new Notification.Builder(context)
.setSound(android.provider.Settings.System.DEFAULT_NOTIFICATION_URI)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("my title")
.setContentText("my text");
Intent resultIntent = new Intent(context, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
}
And to cancel the reminder :
if (alarmManager!= null) {
alarmManager.cancel(PendingIntent.getBroadcast(MainActivity.this,1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
}

How to create a notification service?

Sorry if any of this kind of question has already been posted, i still didnt find the answer that I'm looking for.
My mission is simple - I want to create an app that pushes a notification excatly in 9PM.
Here's what I found and what I currently have -
Intent intent = new Intent();
AlarmManager alarm = (AlarmManager)getSystemService(ALARM_SERVICE);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MINUTE, 6);
cal.set(Calendar.HOUR, 9);
cal.set(Calendar.AM_PM, Calendar.PM);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 1000*60*60*24 , pIntent);
Notification noti = new Notification.Builder(this)
.setTicker("Ticker Title")
.setContentTitle("Content Title")
.setContentText("Notification content.")
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pIntent).getNotification();
noti.flags=Notification.FLAG_AUTO_CANCEL;
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, noti);
I herd there has to be a kind of service to display the notification. How do I create it? If my code's wrong, feel free to re-make it.
Thanks a lot in advance!!

inside manifest
<service android:enabled="true" android:name=".NotifyIntentService" />
<receiver android:name=".AlarmReciever"/>

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:
