I am building an android app to display recurring scheduled notification at a specified time of the day.
For this I have created broadcastReceiver using following code:
public class ScheduleNotification extends BroadcastReceiver {
public static final int NOTIFICATION_ID = 1;
#Override
public void onReceive(Context context, Intent intent) {
long when = System.currentTimeMillis();
MainActivity mainActivity = new MainActivity();
String _pasuram_number = mainActivity.get_pasuram_number();
String[] _pasuram_str = mainActivity.get_dd_text(_pasuram_number).split(",");
Log.d("VC", "Notification intent paasuram " + _pasuram_number);
intent.putExtra("pasuramnumber", _pasuram_number);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Intent snoozeIntent = new Intent(context, MainActivity.class);
PendingIntent piSnooze = PendingIntent.getService(context, 0, snoozeIntent, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setSmallIcon(R.drawable.ic_stat_name);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
builder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_stat_name));
builder.setContentTitle("Title of the notification");
builder.setContentText(_pasuram_str[9]+"-"+_pasuram_str[11]);
builder.setStyle(new NotificationCompat.BigTextStyle().bigText(_pasuram_str[0] + "-" + _pasuram_str[8]));
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, builder.build());
}
}
In the MainActivity added code to create alarm
private void createScheduledNotification(int days)
{
// Get new calendar object and set the date to now
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
// Add defined amount of days to the date
calendar.set(Calendar.HOUR_OF_DAY, 6);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
//calendar.add(Calendar.HOUR_OF_DAY, days * 24);
// Retrieve alarm manager from the system
AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(getBaseContext().ALARM_SERVICE);
// Every scheduled intent needs a different ID, else it is just executed once
int id = (int) System.currentTimeMillis();
// Prepare the intent which should be launched at the date
Intent intent = new Intent(this, ScheduleNotification.class);
// Prepare the pending intent
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// Register the alert in the system. You have the option to define if the device has to wake up on the alert or not
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
//alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
The code compiles fine and application runs, but scheduled notification does not appear as expected.
In the manifest file added receiver as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.vaishnavism.eclass.dinamorudivyaprabandam" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<!-- permission required to use Alarm Manager -->
<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
<!-- Register the Alarm Receiver -->
<receiver android:name="com.vaishnavism.eclass.dinamorudivyaprabandam.ScheduleNotification"/>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SettingsActivity"
android:label="#string/title_activity_settings"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.vaishnavism.eclass.dinamorudivyaprabandam.MainActivity" />
</activity>
</application>
</manifest>
Any help to resolve the issue is greatly appreciated.
Thanks
Try to use set your alarm like below :
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 6);
calendar.set(Calendar.MINUTE, 0);
int interval = 1000 * 60 * 60 * 24;
Intent myIntent = new Intent(yourActivity.this, ScheduleNotification .class);
pendingIntent = PendingIntent.getBroadcast(UserDashBoardActivity.this, 0, myIntent,0);
/* Repeating on every 24 hours interval */
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), interval, pendingIntent);
And you need to start an Alarm When the Device Boots.
For more info refere here.
Hope it will help you.

I am using notifications in my application and everything works well - the notification is showing at desired time to me, even after device reboot.
However, when I click the special button to close all apps, so it closes my app, the notification is not showing at all.
"The special button to close all apps" - I mean the one where you can list all the background apps and then with one click kill them all.
I am testing everything on OnePlus 3T.
Is it possible to run the service again after that "kill all apps" click ?

I need to start alarm at every 30 seconds, I need it to be activated without running the app. But whether the app runs or not the AlarmReceiver do not get called. Any suggestions?
start method is in MainActivity.java class
public void start() {
Calendar calendar=Calendar.getInstance();
calendar.add(Calendar.SECOND, 30);
Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pintent = PendingIntent.getService(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pintent);
Log.d("alarm","alarm set for alarm receiver");
}
My Receiver file
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Toast.makeText(context,"Alarm Receiver ",Toast.LENGTH_SHORT).show();
Log.d("Alarm","Alarm receive");
}
}

here i am able to set alarm, but i didn't receive alarm
In this page there is a finished example of what you need:
https://www.thepolyglotdeveloper.com/2014/10/use-broadcast-receiver-background-services-android/
Apparently you have to change the line:
PendingIntent pintent = PendingIntent.getService(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
To
PendingIntent pintent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Change your start method to this:
public void start() {
Intent alarmIntent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0);
AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
int interval = 30 * 1000; // 30 seconds of interval.
manager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), interval, pendingIntent);
Toast.makeText(this, "Alarm Set", Toast.LENGTH_SHORT).show();
}
Let me know if works.
I ran into this issue recently. The problem was with my custom Parcelable object, using primitives instead worked fine. This answer helped me: Sending Extras to onReceive only retrieves ALARM_COUNT
Here is my code below, what is the problem? If i look at log, there is no start of AlarmReceiver class. So no notification is sent to user. I tried every minute in loop and still nothing happened. What am i doing wrong?
Thanks in Advance!!
public void setRepeatingAlarm(int hour, int min)
{
Intent myIntent = new Intent(this , AlarmReceiver.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, min);
calendar.set(Calendar.SECOND, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24 * 60 * 60 * 1000, pendingIntent);
}
//Receiver Class AlarmReceiver
public void onReceive(Context context, Intent intent)
{
taskDb = new TaskDb(context);
PendingIntent pIntent = PendingIntent.getActivity(context, 0, intent, 0);
String temp ="";
for(String s: taskDb.selectTodayTasks())
{
temp +="-" + s + "\n";
}
if(!temp.equals("")) {
Notification n = new Notification.Builder(context)
.setContentTitle(context.getString(R.string.today_tasks))
.setContentText(temp)
.setLights(Color.CYAN,500,500)
.setContentIntent(pIntent)
.setPriority(Notification.PRIORITY_MAX)
.setAutoCancel(true).build();
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(MainActivity.NOTIFICATION_SERVICE);
notificationManager.notify(0, n);
}
}

Change PendingIntent.getService to PendingIntent.getBroadcast:
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, 0);
Because PendingIntent.getService is used to Retrieve a PendingIntent that will start a service,... but PendingIntent.getBroadcast for Retrieve a PendingIntent that will perform a broadcast,...
I have looked through a ton of documentation and stackoverflow questions on how to set a repeating notification set to a certain time but can not get any of them to work. Here is what I have right now.
The method I set up the AlarmManager in:
//set alarm method
private void setAlarm() {
if(enableCheckBox.isChecked()) {
//save time / title / message
mTinyDB.putInt(Constants.SAVED_HOUR, timePicker.getCurrentHour());
mTinyDB.putInt(Constants.SAVED_MINUTE, timePicker.getCurrentMinute());
mTinyDB.putString(Constants.SAVED_TITLE, titleEditText.getText().toString().trim());
mTinyDB.putString(Constants.SAVED_MESSAGE, messageEditText.getText().toString().trim());
mTinyDB.putBoolean(Constants.SAVED_NOTIFICATION_ENABLED, enableCheckBox.isChecked());
//create repeating notification
Intent intent = new Intent(NotificationActivity.this, Notify.class);
AlarmManager manager = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this,
0, intent, 0);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, mTinyDB.getInt(Constants.SAVED_HOUR, 0));
cal.set(Calendar.MINUTE, mTinyDB.getInt(Constants.SAVED_MINUTE, 0));
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
manager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 24 * 60 * 60 * 1000, pendingIntent);
}
}
The Notify class which extends BoradcastReceiver:
public class Notify extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
TinyDB mTinyDB = new TinyDB(context);
Notification builder = new Notification.Builder(context)
.setContentTitle(mTinyDB.getString(Constants.SAVED_TITLE))
.setContentText(mTinyDB.getString(Constants.SAVED_MESSAGE))
.setSmallIcon(R.drawable.ic_action_check)
.setContentIntent(pIntent)
.build();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, builder);
}
}
Am I doing this completely wrong? I can't get anything to come up (at least at the set time). Help or guidance is appreciated :)
You're using PendingIntent.getService, but your intent is not for a service. For a BroadcastReceiver, you should be using PendingIntent.getBroadcast.
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
The problem you're running into is that you can't set an exact, repeatable alarm in Android. If you want your repeating alarm to occur at an exact time, you must set a one time exact alarm and recreate it after the alarm goes off in your code.
Citation: Documentation for setRepeating
In order for the system to be able to launch a component, it should be registered in your manifest:
AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mypackage.myapplication" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".Notify" />
</application>
</manifest>
I am trying to create reminder using alarm manager. But seems it's not working. I am trying to set multiple reminder using different id but my broadcastreceiver not getting called. I am not seeing any notification or nor any sound.
I have tried 30-40 times.
I am setting date to calender like 25/11/2014
Here is myactivity code which setting alarm notification.
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, 2014);
calendar.set(Calendar.MONTH, 11);
calendar.set(Calendar.DAY_OF_MONTH, 25);
calendar.set(Calendar.HOUR_OF_DAY, 19);
calendar.set(Calendar.MINUTE, 30);
//calendar.set(Calendar.SECOND, 1);
Intent myIntent = new Intent(CreateReminder.this, MyReceiver.class);
myIntent.putExtra("reminder_id",reminderid);
myIntent
.setAction("com.sandeep.alarm.REMINDER");
PendingIntent pendingIntent = PendingIntent.getBroadcast(
CreateReminder.this, reminderid, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
pendingIntent);
MyReceiver.class
public class MyReceiver extends BroadcastReceiver {
private Ringtone r;
#SuppressWarnings("deprecation")
#Override
public void onReceive(Context context, Intent intent) {
int ID=intent.getExtras().getInt("reminder_id");
Log.i("CreateReminder", "reminder_id:-"+ID);
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, "reminder", when);
String title = context.getString(R.string.app_name);
String subTitle = "Please complete task";
Intent notificationIntent = new Intent(context, ReminderActivity.class);
notificationIntent.putExtra("reminder_id", ID);
PendingIntent intent1 = PendingIntent.getActivity(context, 0,notificationIntent, 0);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
notification.setLatestEventInfo(context, title, subTitle, intent1);
//To play the default sound with your notification:
//notification.defaults |= Notification.DEFAULT_SOUND;
notification.flags |= Notification.FLAG_INSISTENT;
//notification.defaults |= Notification.;
notificationManager.notify(0, notification);
Uri notification1 = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
r = RingtoneManager.getRingtone(context, notification1);
r.play();
new Handler().postDelayed(new Runnable(){
public void run() {
r.stop();
}
}, 10000);
}
}
I am registering my receiver in AndroidManifest.xml with permissions.
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
<uses-permission android:name="android.permission.VIBRATE" />

android:exported="false" >
<intent-filter>
<action android:name="com.sandeep.alarm.REMINDER" />
</intent-filter>
</receiver>
</application>
I don't understand why it's not working. Please give me some hints or reference.
You are not sending your broadcast after you set your action in your intent.
Intent myIntent = new Intent(CreateReminder.this, MyReceiver.class);
myIntent.putExtra("reminder_id",reminderid);
myIntent
.setAction("com.sandeep.alarm.REMINDER");
sendbroadcast(myIntent);//YOU FORGOT TO ADD THIS
I have compared your code to mine and have a couple of things for you to try...
Is com.sandeep.alarm a real namespace? The activities within your app have the differing namespace com.sandip.remindme so you could use this ("com.sandip.remindme.REMINDER") for your action name.
Your intent is created with a specific context and class target. Try constructing it with just the action name, then you will know if the action name is the issue:
Intent myIntent = new Intent("com.sandip.remindme.REMINDER")
I'm also working on Alarm remainder and I've implemented successfully in my app. you can download the example code in the following link. I hope it helps you. Please note that alarm takes 30secs to 1 min to call broadcast receiver. i.e., if you set alarm at 3:30:00pm then broad cast receiver will be called at around 3:30:30pm.

You're never sending the broadcast.
sendbroadcast(myIntent);
Add that directly after you do .setAction, and the code should work just fine.
