Android Push Notification Not opening the Activity if n number of notifications in Notification Bar

I am developing an android app and i am implemented GCM push notification also,and notification id is different for each,The problem is When i have n push notifications and app is not in background ,When i click on the notification first time it will open the activity. Then i again cleared the app instance from background and clicked on the another push notification it will not open the app.
Intent intent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(intent);
long[] vibrate = {0, 100, 200, 300};
Uri notification = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
PendingIntent contentIntent = stackBuilder.getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT
| PendingIntent.FLAG_ONE_SHOT);
Bitmap largIcon = BitmapFactory.decodeResource(this.getResources(),
R.mipmap.ic_launcher);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
this).setSmallIcon(R.mipmap.small_icon_notification)
.setContentTitle(getResources().getString(R.string.app_name))
.setLargeIcon(largIcon)
.setSound(notification)
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg). setSound(notification)
.setStyle((new NotificationCompat.BigTextStyle()).bigText(msg)) .setAutoCancel(true);
mBuilder.setVibrate(vibrate);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify((int) System.currentTimeMillis(), mBuilder.build());

In the line(s)
PendingIntent contentIntent = stackBuilder.getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT
| PendingIntent.FLAG_ONE_SHOT);
you always use the same request code for the PendingIntent.
All instances of PendingIntent with the same request code (first argument) and same intent (maybe even that is unimportant, I did not test that yet) are the same pending intent, no matter what extras you put to the intent. The only way to make them different is to use different request codes.
Especially if you use the FLAG_ONE_SHOT, a "Flag indicating that this PendingIntent can be used only once"

I removed PendingIntent.FLAG_ONE_SHOT and pending intent request code to a random number. Now it works fine.

Android click on notification does not open the attached Activity

I want to open an Activity when I click on the notification from the Status bar. I have seen this answered on StackOverflow but none of these answers work for me.
This issue is only seen on Lollipop devices and best way to reproduce is:
1. launch the app.
2. Back ground the app.
3. Receive a push notification.
4. Click on the notification and try with 3-4 push notifications.
Below is my code: I have also tried the following:
adding Intent.ACTION_MAIN
Intent.CATEGORY_LAUNCHER to the intent
PendingIntent.FLAG_UPDATE_CURRENT.
android:exported="true" in my AndroidManifest.xml
but nothing works. I am seeing this issue only on Lollipop devices.
Please note I see this issue intermittently. Is this something related to the intent getting cached and not getting delivered. Please help.
PendingIntent pendingIntent = getPendingIntent(context, payload);
Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_stat)
.setContentTitle(res.getString(R.string.app_name))
.setContentText(payload.getMessage())
.setTicker(payload.getMessage())
.setContentIntent(pendingIntent)
.setSound(soundUri);
private PendingIntent getPendingIntent(Context context, NotificationPayload payload) {
int requestID = (int) System.currentTimeMillis();
Intent intent = new Intent(context, DeepLinkActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setPackage(BuildConfig.APPLICATION_ID);
intent.putExtra(NotificationHelper.KEY_NOTIFICATION_PAYLOAD, payload);
return PendingIntent.getActivity(context, requestID, intent, PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
}

try adding Intent.FLAG_ACTIVITY_CLEAR_TASK flag in the intent
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
this seems to solve my problem

Have you set the pending intent in the notification setContentIntent method?
Try this, it works for me on all api versions
Intent intent = new Intent(this, TestActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.logo)
.setContentTitle(getResources().getString(R.string.notification_title))
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());

Notification does not work properly on some devices

In my app I use a service for background work(send data to server) when my app is in the background.So I create a notification which tells to the user that app is running in the background.I want when the user taps on the notification my app to come to the foreground so I use an Intent like this that android use to launch my app
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.final_driver_notification_icon)
.setContentTitle("...")
.setContentText("...");
final Intent notintent = new Intent(getApplicationContext(),EntryScreen.class);
notintent.setAction(Intent.ACTION_MAIN);
notintent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent pendint = PendingIntent.getActivity(this, 0, notintent, 0);
mBuilder.setContentIntent(pendint);
int notID = 001;
startForeground(notID, mBuilder.build());
In the emulator and some physical devices works perfect.But in some other it launches the app from the start(It puts Entry screen in the top).
Any idea why is this happening?

You should start your service with startForeground(). this is the way to start a service in foreground and report by a notification. Android - implementing startForeground for a service?
or try something like this:
public void initForeground() {
Intent intentForeground = new Intent(this, Activity.class);
intentForeground.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intentForeground,0);
pendingIntent.cancel();
pendingIntent = PendingIntent.getActivity(this, 0, intentForeground,0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.drawable.icon)
.setContentIntent(pendingIntent)
.setContentTitle(getString(R.string.app_name))
.setContentText(getString(R.string.something))
.setTicker(getString(R.string.something))
.setAutoCancel(false);
Notification notification = mBuilder.build();
startForeground(myID, notification);
}
Hope it helps you!

Intent data not updated in activity while launched from andorid push notification click

I am using Google cloud messaging for my android application.GCM part is running successfully.Now I want to show the message in a UI activity when the user taps on the notification icon in the status bar.
I am launching my ResultShowActivity from the notification using the following code.
Intent notificationIntent = new Intent(context, ResultShowActivity.class);
notificationIntent.putExtra("Message",msg);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
this).setSmallIcon(R.drawable.gcm_cloud)
.setContentTitle("GCM Notification")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setAutoCancel(true)
.setSound(alarmSound)
.setContentText(msg);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
The message is being sent properly,and shown correctly when the GCM notification appears but when I capture the extras of intent in ResultShowActivity it is always showing the old message.
I am using following code to receive message from intent in ResultShowActivity.
String GCMMsg = showViewIntent.getStringExtra("Message");
I have tried removing the in ResultShowActivity by using
intent.removeExtra("Message");
or
intent.replaceExtras(extras);
Can anyone please suggest how to retrieve the updated message from intent.Thanks for any help regarding this.

Please use following code
int iUniqueId = (int) (System.currentTimeMillis() & 0xfffffff);
PendingIntent contentIntent = PendingIntent.getActivity(this,iUniqueId,notificationIntent, 0);
Instead of following line of code
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
Hope this will help

You need to add Intent.FLAG_ACTIVITY_SINGLE_TOP to intent flag and PendingIntent.FLAG_UPDATE_CURRENT to pending intent flag.
Intent intent = new Intent(this,YourActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent =
PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
Important: Make sure to implement onNewIntent(Intent intent). This function will be called when your activity is in foreground.

android clear intent which send from notification

My app is getting called by an intent that is passing information(pendingintent in statusbar) but when I hit the home button and reopen my app by holding the home button it calls the intent again and the same extras are still there...
is there any way to clear the intent? or check whether it has been used before?
Intent intent = new Intent(context, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("reportID", reportID);
intent.putExtra("message", message);
intent.putExtra("toast_show", true);
intent.putExtra("detail_open", true);
intent.putExtra("SplashActivity", true);
PendingIntent pendingIntent = PendingIntent
.getActivity(context.getApplicationContext(), 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT
| PendingIntent.FLAG_ONE_SHOT);
// Intent.FLAG_ACTIVITY_NEW_TASK
/* get the system service that manage notification NotificationManager */
NotificationManager notificationManager = (NotificationManager) context
.getApplicationContext().getSystemService(
Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
context.getApplicationContext())
.setWhen(when)
.setContentText(message)
.setContentTitle(title)
.setSmallIcon(smalIcon)
.setAutoCancel(true)
.setTicker(message)
.setLargeIcon(largeIcon)
.setDefaults(
Notification.DEFAULT_LIGHTS
| Notification.DEFAULT_VIBRATE
| Notification.DEFAULT_SOUND)
.setContentIntent(pendingIntent);
/* Create notification with builder */
Notification notification = notificationBuilder.build();
notificationManager.notify(0, notification);
The problem starts when I receive a notification. If I start the app from the notification, it starts the correct screen and I can use the app => ok. But when I quit the app (with home or back button) it do not appears anymore in the "recent app" list. More precisely:
Does anyone knows how to keep the app in the "recent app" list after being started form a notification?

Update this line and try
PendingIntent pendingIntent = PendingIntent.getActivity(context, (int)(Math.random() * 100),intent,PendingIntent.FLAG_UPDATE_CURRENT);

What you need is the PendingIntent.FLAG_CANCEL_CURRENT :
If the described PendingIntent already exists, the current one is canceled before generating a new one. You can use this to retrieve a new PendingIntent when you are only changing the extra data in the Intent; by canceling the previous pending intent, this ensures that only entities given the new data will be able to launch it.
PendingIntent pendingIntent = PendingIntent.getActivity(
context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
This will ensure that your latest data will pe present on your Intent.
