I am really new to android, I have been researching about alarms. I want to alarm if there is a birthday on that day. I've have used alarm manager. I was confused because i have read that it clears after reboot. I don't have an android phone so I'm just using the emulator.
Here's my code :
public void schedAlarm() {
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent = new Intent(this, AlarmService.class);
pendingIntent = PendingIntent.getBroadcast(this, contact.id, intent, PendingIntent.FLAG_ONE_SHOT);
am.setRepeating(AlarmManager.RTC, timetoAlarm, nextalarm, pendingIntent);
}
I made this BroadcastRecever in replace for AlarmSerivce
Here :
public void onReceive(Context context, Intent intent) {
nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence from = "It Birthday!";
CharSequence message =" Greet your friend.";
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(), 0);
Notification notif = new Notification(R.drawable.ic_launcher, "Birthday", System.currentTimeMillis());
notif.setLatestEventInfo(context, from, message, contentIntent);
nm.notify(1, notif);
}
is this enough??
A simple answer would be NO. But yes you can achieve this by creating a BroadCastReceiver which will start the Alarm while booting completes of the device.
Use <action android:name="android.intent.action.BOOT_COMPLETED" /> for trapping boot activity in BroadCastReceiver class.
You need to add above line in AndroidManifest.xml as follows,
<receiver android:name=".AutoStartUp" android:enabled="true" android:exported="false" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Yes , you can make AlarmManager to work even after rebooting.
Perhaps this is the easiest way : add the below code in your AndroidManifest.xml:
<receiver android:name=".AlarmReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
don't forget to include user-permission to the AndroidManifest.xml as:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
in some phones only adding
<action android:name="android.intent.action.Boot_COMPLETED" />
does not work you also have to add
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
along with previous one

I have to show notification to user at user's selected time and date and my code is below.
public static void setAlarm(Context context, long id, int rYear, int rMonth, int rDay, int rHour, int rMinute) {
if (Share.wantReminder) {
Share.wantReminder = false;
Calendar calendar = new GregorianCalendar(rYear, rMonth, rDay, rHour, rMinute);
Calendar calendar1 = new GregorianCalendar();
calendar1.setTimeInMillis(System.currentTimeMillis());
calendar1.set(Calendar.YEAR, calendar.get(Calendar.YEAR));
calendar1.set(Calendar.MONTH, calendar.get(Calendar.MONTH));
calendar1.set(Calendar.DAY_OF_MONTH, calendar.get(Calendar.DAY_OF_MONTH));
calendar1.set(Calendar.HOUR_OF_DAY, calendar.get(Calendar.HOUR_OF_DAY));
calendar1.set(Calendar.MINUTE, calendar.get(Calendar.MINUTE));
Intent intent = new Intent(context, ReminderService.class);
intent.setAction(String.valueOf(id));
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar1.getTimeInMillis(), pendingIntent);
Toast.makeText(context, "Alarm set", Toast.LENGTH_SHORT).show();
}
}
My Manifest.xml
<receiver android:name=".service.ReminderService">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
No notification are comes to actionbar
What should I do?
Please share ReminderService.class
you must have the notification settings complete to trigger this place.
<receiver android:name=".ReminderService">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
My method is triggered here and it doesn't accept service per
<receiver android:name=".AlarmReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.TIME_SET" />
<action android:name="android.intent.action.TIMEZONE_CHANGED" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
Make below changes to your receiver in Manifest.xml
<receiver
android:name=".service.ReminderService"
android:process=":remote"
android:excludeFromRecents="true" />
Create and display notification inside onReceive() method of ReminderService class as shown below.
public class ReminderService extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
wl.acquire();
//Put your code here to create notification
wl.release();
}
}
Add below permission in your Manifest.xml
<uses-permission android:name="android.permission.WAKE_LOCK" />
After a Push Notification is received, I want to open an Àctivity when the Notification is pressed.
Here are my Services:
public class GCMIntentService extends GcmListenerService {
#Override
public void onMessageReceived(String from, Bundle data) {
String title = data.getString("title");
String message = data.getString("message");
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(message)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setTicker(message)
.setAutoCancel(true);
mBuilder.setDefaults(Notification.DEFAULT_LIGHTS);
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
mBuilder.setDefaults(Notification.DEFAULT_VIBRATE);
Intent myIntent = new Intent(this, MyActivity.class);
PendingIntent intent2 = PendingIntent.getBroadcast(this, 1, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(intent2);
notificationManager.notify(1, mBuilder.build());
}
public class GCMIDListenerService extends InstanceIDListenerService {
#Override
public void onTokenRefresh() {
InstanceID instanceID = InstanceID.getInstance(this);
String token;
try {
token = instanceID.getToken(Resources.getSystem().getString(R.string.gcm_defaultSenderId), GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
} catch (IOException e) {
e.printStackTrace();
}
//TODO:send token to the server
}
}
I just did everything following the Google documentation. I implemented that feature for another project sometime ago but it was a bit different, I used my own 'BroadcastReceiver' instead of the 'com.google.android.gms.gcm.GcmReceiver' provides by Google.
Here is my Manifest:
<application>
...
<!-- GCM Push Notifications Config -->
<receiver
android:name="com.google.android.gms.gcm.GcmReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="gcm" />
</intent-filter>
</receiver>
<service
android:name=".push.GCMIntentService"
android:exported="false" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
<service
android:name=".push.GCMIDListenerService"
android:exported="false">
<intent-filter>
<action android:name="com.google.android.gms.iid.InstanceID" />
</intent-filter>
</service>
</application>
Any ideas? Am I missing something?
Here some documentation I have follow:
Google official documentation
CGM tutorial By Dustin Rothwell
And of course I have researched a lot here at stackoverflow.
Thanks!
You have done one minor mistake. You are writing this code for opening activity.
PendingIntent intent2 = PendingIntent.getBroadcast(this, 1, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(intent2);
As you want to open activity you need to create pending intent using getActivity method instead of getBroadcast method.
Hope this will help.
I'm trying to trigger a notification every 15 minutes, starting from the time I set. Currently my app notifies only when my application is open or when it is in the recent applications but when i closed my application the notification doesn't work any longer but when i open again my app it will trigger the notification. Based on my research I need a Service. So I have 3 files.
In my MainActivity, i set the alarm
private void scheduleNotification(int week){
Intent notificationIntent = new Intent(this, NotificationPublisher.class);
notificationIntent.putExtra("notifId", getResources().getInteger(R.integer.notification_id));
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, getResources().getInteger(R.integer.notification_id), notificationIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.DAY_OF_WEEK, week);
calendar.set(Calendar.HOUR_OF_DAY, 9);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmManager.INTERVAL_FIFTEEN_MINUTES, pendingIntent);
}
in the MainActivity i call a BroadcastReceiver which is the NotificationPublisher. Here is my NotificationPublisher
public class NotificationPublisher extends BroadcastReceiver {
final String TAG = "NotificationPublisher";
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, NotificationAlarmService.class);
service.putExtra("notifId", intent.getIntExtra("notifId", 0));
context.startService(service);
}
then I start a service by using the BroadcastReceiver which is the NotificationAlarmService, here i build a Notification using NotificationCompat.Builder.
public class NotificationAlarmService extends Service {
. . . .
#Override
public int onStartCommand(Intent intent,int flag, int startId)
{
notificationManager = (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent mIntent = new Intent(this, MainActivity.class);
pendingIntent = PendingIntent.getActivity(this, intent.getIntExtra("notifId", 0), mIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle("App");
builder.setContentText("Notify Me");
builder.setAutoCancel(true);
builder.setSmallIcon(getNotificationIcon());
builder.setContentIntent(pendingIntent);
notificationManager.notify(intent.getIntExtra("notifId", 0), builder.build());
return super.onStartCommand(intent, flag, startId);
}
I already tried returning START_STICKY instead of super.onStartCommand I understand that when i used a service it will run in the background even if the user closed the application. I also tried changing this and used getBaseContext() in the service but this it doesn't trigger the notification. I don't know if i'm missing something. Thank you in advance.
EDIT
Here is my Manifest
<receiver android:name=".NotificationPublisher"
android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<service android:name=".NotificationAlarmService"
android:enabled="true">
</service>
After a week, I finally got it. In my Manifest i put something like this
<receiver android:name=".NotificationPublisher">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
<service android:name=".NotificationAlarmService"
android:enabled="true"
android:exported="false" >
<intent-filter>
<action android:name="NOTIFICATION_SERVICE" />
</intent-filter>
</service>
i've removed the enabled="true" in the receiver and also add QUICKBOOT_POWERON. Then add an action in the service which is NOTIFICATION_SERVICE and call it in my service like this
NotificationManager mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
Try adding Service in your Manifest file (Same as declaring an Activity) under application tag like this,
<service android:name="com.example.android.NotificationAlarmService">
</service>
I am trying to setup an alarm at a specified time, but it is not being caught in my reciver.
Setup:
Intent intent = new Intent(this, ActionReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
Calendar current = Calendar.getInstance();
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, (current.getTimeInMillis() + 60000),3600000, pendingIntent);
Here is my reciver:
public class ActionReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras(); //breakpoint here that doesn't get triggered
}
}
I have put these values in my manifest:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<receiver android:name="com.project.ActionReceiver" android:enabled="true" />
Not sure what is wrong... thanks!
Finally got the receiver to fire! I added the following code to my manifest:
<receiver
android:name="com.project.ActionReceiver"
android:exported="true" >
<intent-filter>
<action android:name="com.project.ActionSetter" >
</action>
</intent-filter>
</receiver>
Found here with details: https://stackoverflow.com/a/16119351/1174574
The name of receiver in your manifest should be class name, such as:
<receiver android:name="com.project.ActionReceiver">
BTW, set an action is a better practice.
Intent intent = new Intent(this, ActionReceiver.class);
intent.setAction("com.project.action.ALERM");
And in the manifest
<receiver android:name="com.project.ActionReceiver">
<intent-filter>
<action android:name="com.project.action.ALERM"/>
</intent-filter>
</receiver>
Try changing the android:name attribute of your receiver to the fully qualified class name of your ActionReceiver. Something like:
<receiver android:name="com.project.ActionReceiver" android:enabled="true" />
I am creating an service which is use Service Component ,I want to run the application always in background . Suppose i switch off the mobile and when i on the mobile our application is closed i.e. automatically.
am trying this code
androidManifest.xml
<receiver android:name=".receiver.ConnectionReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
and adding this code in BroadCastreceiver Class
update
private class ConnectionReceiver extends BroadcastReceiver{
private Timer mTimer;
private TimerTask mTimerTask;
private long interval;
#Override
public void onReceive(Context context, Intent intent) {
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, ConnectionReceiver.class), PendingIntent.FLAG_UPDATE_CURRENT);
am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, interval, pi);
{
calGps();
}
}
Hi Leema Rose
You want to launch your service/activity after the device booted. Check the below links you will understand how to use BroadcastReceiver.
Autostart an application at bootup
Start Service at boot
I hope it may help you.
New Answer:
Add <category android:name="android.intent.category.HOME" /> in intent-filter of receiver's manifest file.
You have to add a manifest permission entry:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
(of course you should list all other permissions that your app uses).
Then, implement BroadcastReceiver class, it should be simple and fast executable. The best approach is to set an alarm in this receiver to wake up your service (if it's not necessary to keep it running ale the time as Prahast wrote).
public class BootUpReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, MyService.class), PendingIntent.FLAG_UPDATE_CURRENT);
am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, interval, pi);
}}
Then, add a Receiver class to your manifest file:
<receiver android:enabled="true" android:name=".receivers.BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
