local Notification on click open an activity

I have a local notification which is set in one of my receivers. Onclick of notification I want to open a specific activity. Below is my code.
NotificationCompat.Builder builder =
(NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Its Your day!!")
.setContentText(message)
.setAutoCancel(true);
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIntent);
// Add as notification
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(times, builder.build());
But this is not working. On Click of notification it just removes notification from status bar. Am I missing anything ?

try this :
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
instead of this :
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
use this codes before your notification builder code.
now this is the full version :
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder builder =
(NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Its Your day!!")
.setContentText(message)
.setAutoCancel(true)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(times, notificationBuilder.build());
try to use this. i hope you will get you desire answer.
UPDATE
here is the sample project : https://github.com/ImtiazDipto01/SimpleNotification

Add Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP as Flag on your `Intent. Like -
notificationIntent .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
Also provide unique id for notification. like -
int uniqueNotificationId = (int) (System.currentTimeMillis() & 0xfffffff);
PendingIntent contentIntent = PendingIntent.getActivity(context, uniqueNotificationId , notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
Also on -
manager.notify(uniqueNotificationId , builder.build());

Notification action not working in Android

I have this code
Intent launchIntent = new Intent(context,WidgetAlarmManagerActivity.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, launchIntent, 0);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Nicilis")
.setTicker(messageBody)
.setContentText(messageBody)
.setAutoCancel(true)
.addAction(android.R.drawable.ic_menu_close_clear_cancel, "Cancel Upload", pendingIntent)
.setSound(defaultSoundUri);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
The action is in the notification but when I press it, nothing happen
Thanks a lot

Intent launchIntent = new Intent(context,WidgetAlarmManagerActivity.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, launchIntent, 0);
getBroadcast() returns a PendingIntent that will invoke sendBroadcast() on the wrapped Intent. getActivity() returns a PendingIntent that will invoke startActivity() on the wrapped Intent. WidgetAlarmManagerActivity seems like the name for an activity, suggesting that you should replace getBroadcast() with getActivity().

I think instead of
pendingIntent = PendingIntent.getBroadcast(context, 0, launchIntent, 0);
you should use be using
pendingIntent = PendingIntent.getActivity(context,
0, launchIntent,
PendingIntent.FLAG_CANCEL_CURRENT);

Android AlarmManager putExtra to PendingIntent and NotificationCompat.Builder

I'm trying to putExtra to Activity which will be launched after clicking on notification, but instead of value that I set I'm getting default value. This is my code in AlarmReceiver:
Intent notifActiv = new Intent(context, NotificationActivity.class);
notifActiv.putExtra("ID", id);
PendingIntent pI = PendingIntent.getActivity(context, 0, notifActiv, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
context).setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(string).setTicker("You got meeting today!")
.setContentText("Click here for more details");
mBuilder.setContentIntent(pI);
mBuilder.setDefaults(NotificationCompat.DEFAULT_VIBRATE);
mBuilder.setAutoCancel(true);
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, mBuilder.build());
And this is my NotificationActivity where I'm trying to get Extras:
Intent intent = getIntent();
int id = intent.getIntExtra("ID", 0);
Could you please tell my where I'm doing something wrong?

How to open a specific activity based on Notification

I am currently working on a reminders app in which the user gets a notification with the name of the reminder and is then redirected to an activity which contains the text of the reminder in detail.
I am however, only able to redirect to the same activity each time.
I am using this code :
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0);
notification.setLatestEventInfo(this, title, text, contentIntent);
So this redirects to the MainActivity on clicking the notification. I would like to redirect to a separate screen and then based on a key value display a text on that activity.
How do I achieve this ?
Thanks

Just change the PendingIntent using another Activity and/or append extra information on the Intent you are using to create the PendingIntent:
Intent launchIntent = new Intent(this, AnotherActivity.class)
launchIntent.putExtra("myKey", "myValue");
//....
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, launchIntent , 0);
notification.setLatestEventInfo(this, title, text, contentIntent);
And than, in you Activity's onCreate():
//...
getIntent().getStringExtra("myKey")
//do your stuff..

Just pass the value in the intent . eg.
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0);
contentIntent.putExtra("phone", value);
contentIntent.putExtra("name", value);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, contentIntent,
PendingIntent.FLAG_CANCEL_CURRENT);

Question has already been anwered and accepted, but here's another method:
int mId = 1;
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, TwoActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);
Notification.Builder builder = new Notification.Builder(this)
.setContentIntent(pendingIntent)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Title")
.setContentText("Content")
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true)
.setNumber(1);
NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(mId, builder.build());

Push notification open Activity with same intent

I receive push notifications with data(intent). If I received two or more notifications with different ids, but open one Activity and ids are same. For example, I receive three notifications with different id=1,2,3. But when Activity is started use one id = 3. When I click first or second notification with ids 1 and 2, open Activity with id 3.Can you help understand my mistake in the code?
NOTIFICATION_ID ++;
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(msg.getString("title"))
.setContentText(msg.getString("message"))
.setDefaults(Notification.DEFAULT_SOUND)
.setStyle(new NotificationCompat.BigPictureStyle().bigPicture(Picasso.with(getApplicationContext()).load(msg.getString("icon")).get()).setSummaryText(msg.getString("message")))
.setAutoCancel(true);
Log.e("msg---",msg.toString());
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName(this, ActivityDetail.class));
// intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
// intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.putExtra(Keys._PostId,msg.getString("id"));
intent.putExtra(Keys._Image, msg.getString("icon"));
intent.putExtra(Keys._PostType, msg.getString("post_type"));
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

Create your PendingIntent like this and do a trick
PendingIntent contentIntent = PendingIntent.getActivity(this, (int) (Math.random() * 100), intent, PendingIntent.FLAG_UPDATE_CURRENT);
