I want to send notification by BroadcastReceiver. Notification sent by AlarmReceiver but again sent notification when i clicked the notification. The same thing happens again, again and again like endless loop
Here is my AlarmReceiver.java
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
android.support.v7.app.NotificationCompat.Builder builder = new android.support.v7.app.NotificationCompat.Builder(context);
builder.setSmallIcon(R.mipmap.ic_launcher);
// This intent is fired when notification is clicked
Intent i = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, i, 0);
// Notifcation notify sound
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
// Set the intent that will fire when the user taps the notification.
builder.setContentIntent(pendingIntent);
// Large icon appears on the left of the notification
builder.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher));
// Content title, which appears in large type at the top of the notification
builder.setContentTitle("Have a good weekend");
//Notification click after clear notification
builder.setAutoCancel(true);
//Set notification sound
builder.setSound(alarmSound);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Will display the notification in the notification bar
notificationManager.notify(1, builder.build());
}
}
and MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setAlarm();
}
private void setAlarm(){
AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent alarmIntent = new Intent(MainActivity.this, MyAlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, alarmIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.DAY_OF_WEEK,6);
calendar.set(Calendar.HOUR_OF_DAY,16);
calendar.set(Calendar.MINUTE,53);
calendar.set(Calendar.SECOND,0);
manager.setInexactRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent);
}
}
As on click on notification it open MainActivity and in onCreate method of this activity you are calling setAlarm() . So on click of notification onCreate method is invoked then setAlarm() is invoked , this again set Alarm and build notification.
Do following changes
call setAlarm() onClick of a button, so that it is not invoked automatically onCreate of activity.
If you want to send notification automatically
change the intent of notification
Intent i = new Intent(context, MainActivity.class);
As of now you are using intent to open ManinActivity on click of notification.
Change Intent to
Intent i = new Intent(context, OtherActivity.class);
OtherActivity is the activity which does not setAlarm() or build notification in onCreate method.
Alternative Method
Use sharedPreferences to check whether the notification is build once or not.
if build once then don't call setAlarm()

I would like to know - how to show pop up window when AlarmManager will call? I've already created AlarmManager now I need to create something what will show popup window to cancel this Alarm.
My code:
public void setAlarm(long timeInMillis){
if(Build.VERSION.SDK_INT >= 23){
mCalendar.set(
mCalendar.get(Calendar.MONTH),
mCalendar.get(Calendar.YEAR),
mCalendar.get(Calendar.DAY_OF_YEAR),
mCalendar.get(Calendar.HOUR_OF_DAY),
mCalendar.get(Calendar.MINUTE)
);
}
final AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, MyAlarm.class);
intent.setData(currentUri);
final PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
alarmManager.setExact(AlarmManager.RTC, timeInMillis, pendingIntent);
}
and
public class MyAlarm extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
MediaPlayer mediaPlayer = MediaPlayer.create(context, Settings.System.DEFAULT_RINGTONE_URI);
mediaPlayer.start();
}
}
onReceive(context, intent) {
/*show the dialog in this method. set the onclick so it can dismiss the alarm,
get the value for the alarm from the bundle. I may be wrong about this
but i think alarmManager has a cancel(PendingIntent operation) method that u can
just send in the intent and your done.
Call a stopMedia(context) method after the cancel in order to stop the media
that is playing
*/
showDialog(context, intent)
//Extract the play media code to a method for readability
playMedia(context)
}
That should solve your problem
Before the code was posted:
We can either use the pending intent and have an activity that handles the pending intent. or use the handler to execute the code.
In either case, create a dialog fragment and then use the appropriate context to show it. setOnClickListener { alarmManager.cancel } for the dialog fragment button.
A little more explanation may be required depending on how the alarm manager is setup
Here there is an activity called grouchat. The messages are sent and received by gcmIntent class. In that class I have the code that issues the notification to the mobile.
In our app more than one event is there for groupchat. If I click the notification, it should take me to the right chat window, so I have passed the eventMO by putExtra parcelable. In the groupchat there is code to get a parcelable
The following is the code in groupchat activity:
eventMO = (EventMO) getIntent().getParcelableExtra("eventMo");
List<ChatMO> chatMOs = dbHelper.getGroupChatMessageForEvent(eventMO.getEventId());
The following code is in gcmIntend class to build the notification:
Intent groupChatActFrag = new Intent(getApplicationContext(), GroupChatActivity.class);
//here i have messageMO so i just set the eventid from messageMO to eventMO according to get the eventID in groupchat Activity
EventMO eventMO = new EventMO();
eventMO.setEventId(messageMO.getEventId());
groupChatActFrag.putExtra("eventMo", eventMO);
groupChatActFrag.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, groupChatActFrag, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_dialog_info)
.setContentTitle(messageMO.getEventTitle())
.setStyle(new NotificationCompat.BigTextStyle().bigText(messageMO.getfromUserName()))
.setContentText(messageMO.getMessage())
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
mBuilder.setContentIntent(contentIntent);
mBuilder.setAutoCancel(true);
Log.e("gcm","eventid"+messageMO.getEventId());
mNotificationManager.notify((int) (long) eventMO.getEventId(), mBuilder.build());
If I clicked the notification it throws a null pointer exception, because I get eventMO as null. Please tell me how to pass the current event id in GcmIntent class to groupchat activity.
I use this code in my projects
Notification
Intent intent = new Intent(context.getApplicationContext(), MainActivity.class);
intent.setAction(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context.getApplicationContext(), id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new NotificationCompat.Builder(context)//
.setContentTitle(title == null ? context.getString(R.string.app_name) : title)//
.setContentText(message)//
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))//
.setSmallIcon(R.drawable.ic_launcher)//
.setContentIntent(pendingIntent)//
.setTicker(context.getString(R.string.app_name))//
.build();
notification.defaults |= Notification.DEFAULT_ALL;
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Service.NOTIFICATION_SERVICE);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(id, notification);
In Activity check intent in onCreate and onNewIntent
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
if (getIntent() != null) {
checkIntent(getIntent());
}
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
checkIntent(intent);
}
private void checkIntent(Intent intent)
{
...
}
You need change getEvent Id to id of notification.
int notification_id = 123;
notificationManager.notify(notification_id, notification);
I have a Timer and I send a notification to the user when the timer finishes, I've added a "Stop" button to my notification and when the user clicks it I want the sound of the timer to stop.
What I tried is registering the action to my BroadcastReceiver in my TimerActivity like this:
filter = new IntentFilter();
filter.addAction(TimerService.BROADCAST_ACTION);
registerReceiver(broadcastReceiver, filter);
this is the BroadcastReceiver inside the TimerActivity:
private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ScheduledService.STOP_TIMER))
{
if(timerAudio.isPlaying())
{
timerAudio.stop();
timerAudio.release();
timerAudio = null;
}
}
};
And this is my how I create the notification inside the ScheduledService class:
Intent notificationIntent = new Intent(getBaseContext(), CookingTimer.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
Intent nextIntent = new Intent(STOP_TIMER);
PendingIntent stopTimer = PendingIntent.getBroadcast(this, 0, nextIntent, 0);
Notification noti = new Notification.Builder(this)
.setContentTitle("This is a sample notification")
.setContentText("Subject")
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pIntent)
.addAction(R.drawable.ic_launcher, "Stop", stopTimer).build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Hide the notification after its selected
noti.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, noti);
I've registered the Service and the action inside my Manifest and I receive the notification correctly, but the button action doesn't work.. Can someone explain me how to fix this?
Post the Activity that has the MediaPlayer controlling the sound.
If you are not receiving Null Pointer Exceptions, I suppose that timerAudio is correct.
However specify if the current view is defined and in context.
So I don't know why this code is not working. I wanted to make an "alarm" notification that would go off once a day. Just wanted to say I'm new to android. Changed up the code a bit couple of times but still wont work.
Alarm method executes notification does too but I get this : -248/? D/PowerManagerService﹕ releaseWakeLock flags=0x1 tag=AlarmManager W/ActivityManager﹕ Unable to start service Intent { flg=0x4 cmp=com.example.polakken.test/.lol (has extras) }: not found 06-13 00:00:00.825 231-267/? D/PowerManagerService﹕ acquireWakeLock flags=0x1 tag=AlarmManager 06-13 00:00:00.825 231-248/? D/PowerManagerService﹕ releaseWakeLock flags=0x1 tag=AlarmManager
My Code:
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = preferences.edit();
int i = preferences.getInt("numberoflaunches", 1);
if (i < 2) {
alarmMethod();
i++;
editor.putInt("numberoflaunches", i);
editor.commit();
}
if (savedInstanceState == null) {
splashMethod();
}
}
//...
private void alarmMethod() {
Intent intentbro = new Intent(this, lol.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intentbro, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.HOUR, 0);
calendar.set(Calendar.AM_PM, Calendar.AM);
calendar.add(Calendar.DAY_OF_MONTH, 1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60 * 60 * 24, pendingIntent);
Toast.makeText(MainActivity.this, "start alarm", Toast.LENGTH_LONG).show();
}
//notification class
public class lol extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
NotificationCompat.Builder b = new NotificationCompat.Builder(this);
Intent intent1 = new Intent(this.getApplicationContext(), MainActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 1, intent1, 0);
b.setContentText("lol");
b.setContentTitle("Default notification");
b.setSmallIcon(R.drawable.iconography_small_size);
b.setContentIntent(pIntent);
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, b.build());
}
}
You are creating the PendingIntent with PendingIntent.getService(), but you are supplying an Intent with an Activity.
So for your code to work you would need to use PendingIntent.getActivity().
(Additionally you have to add the corresponding <activity> tag to your AndroidManifest.xml.)
However, this is probably not exactly what you want: The only thing the lol Activity does is adding a notification. You might want to use a BroadcastReceiver (or perhaps a WakefulBroadcastReceiver) instead. In this case you would need to use PendingIntent.getBroadcast() instead of getActivity().
Follow these steps
1Create an Activity and add this code to setAlarm(can be any name)
Suppose you want to set Alarm for 24/02/15 ,14:00PM
#SuppressLint("UseSparseArrays")
public void setAlarms(Long id,String event_date,String event_time,Context context)
{
Calendar cal=Calendar.getInstance();
String[] parts=event_date.split("/");
String Event_date=parts[0];
String Event_month=parts[1];
String Event_Year=parts[2];
String[] parts1=event_time.split(":");
String Event_HOD=parts1[0];
String Event_MIN=parts1[1];
cal.add(Calendar.YEAR, Integer.parseInt(Event_Year)-cal.get(Calendar.YEAR));
cal.add(Calendar.MONTH, (Integer.parseInt(Event_month)-1)-cal.get(Calendar.MONTH));
cal.add(Calendar.DAY_OF_MONTH, Integer.parseInt(Event_date)-cal.get(Calendar.DAY_OF_MONTH));
cal.add(Calendar.HOUR_OF_DAY, Integer.parseInt(Event_HOD)-cal.get(Calendar.HOUR_OF_DAY));
cal.add(Calendar.MINUTE, Integer.parseInt(Event_MIN)-cal.get(Calendar.MINUTE));
cal.add(Calendar.SECOND, 0);
AlarmManager am =(AlarmManager)context.getSystemService(Activity.ALARM_SERVICE);
//Your BroadcastReceiver which will receive Alarm
Intent intent = new Intent(context, AlarmReceiver.class);
//you can use PutExtra() to send additional parameter with Intent
//PendingIntent to add
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
(int)(long)id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
pendingIntent);
Toast.makeText(context, "alarm Set for Know", Toast.LENGTH_LONG).show();
}
2)Inside BroadcastReceiver onReceive() method
#Override
public void onReceive(Context context, Intent intent) {
//Receive parameter and do what you want to do with parameter
//Using RemoteViews you can Inflate a CustomLayout when user clicks on Notification when you do not want any CustomLayout for Notification remove it
RemoteViews contentView1 = new RemoteViews("com.example.new_reminder_book" , R.layout.custom_notification);
contentView1.setTextViewText(R.id.cn_tv_title, Event_title);
contentView1.setTextViewText(R.id.cn_tv_category, Event_category);
contentView1.setImageViewResource(R.id.cn_tv_image, R.drawable.event);
NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.appicon)
.setContent(contentView1)
.setAutoCancel(true)
.setOngoing(true);
//Target Activity that will start when you click on Notification
Intent result=new Intent(context, EmptyActivity.class);
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(EmptyActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(result);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
Notification notification=mBuilder.build();
notification.contentView=contentView1;
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify((int) System.currentTimeMillis(), notification);
//A mp3 fine in res->raw that will play when notification fire
MediaPlayer mp = MediaPlayer.create(context, R.raw.listen);
mp.start();
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
wl.acquire();
/*Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
//Set pattern for Vibration
long[] pattern={2000,3000,4000};
vibrator.vibrate(pattern,1);*/
wl.release();
}
}
3)Declare Two permissions in Manifest.xml
<uses-permission android:name="android.permission.WAKE_LOCK"/> <uses-permission android:name="android.permission.VIBRATE"/>
4)Declare You AlarmReceiver in Manifest.xml
<receiver android:name=".extra.AlarmReceiver" android:label="#string/title_activity_alarm_receiver" android:exported="true"> </receiver>

I'm developing an android app where I display notifications with actions. But on action click notification not clearing, It stuck in that shade. How do I clear a notification on action click?
MY CODE
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
Intent intent = new Intent(this, SettingsActivity.class);
PendingIntent openSettingsActivity = PendingIntent.getActivity(this,1, intent, PendingIntent.FLAG_CANCEL_CURRENT);
notificationBuilder.addAction(R.drawable.ic_notification_button, "Settings", openSettingsActivity);
notificationBuilder.setPriority(Notification.PRIORITY_MAX);
notificationBuilder.setDefaults(Notification.DEFAULT_VIBRATE);
notificationBuilder.setContentTitle(title);
notificationBuilder.setContentText(text);
notificationBuilder.setAutoCancel(true);
notificationBuilder.setColor(color);
notificationBuilder.setSmallIcon(R.drawable.ic_notification);
notificationBuilder.setContentIntent(openSettingsActivity);
final NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1,notificationBuilder.build());
Hiding notifications should be processed in the place where the intent is sent.
In your current code:
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
Intent intent = new Intent(this, SettingsActivity.class);
intent.putExtra("hide_notification", true); //add boolean to check later in activity if it should remove notification on activity create
And in your activity smth like this, to check if it should remove notification:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//check for notification remove
boolean hideNotification = getIntent().getBooleanExtra("hide_notification", false);
if (hideNotification) {
NotificationManagerCompat nmc = NotificationManagerCompat.from(this);
nmc.cancel(1); //1 - is your notification id
}
}
Depends on what you want, maybe it will be better to call that not in onCreate() but onStart()
