问题
I am using this code to show the local notification and When notification comes then on click of notification want to launch the ListActivity but on Google nexus device ListActiviy is not launches when click on notification, but on other device this code is working well.
Intent notificationIntent = new Intent(context,
ListActivity.class);
notificationIntent.putExtra("clicked", "Notification Clicked");
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); // To open only one activity on launch.
PendingIntent pIntent = PendingIntent.getActivity(context, reqCode,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager nM = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder notify = new NotificationCompat.Builder(
context);
notify.setContentIntent(pIntent);
notify.setSmallIcon(R.drawable.app_icon);
notify.setContentTitle("Hello World");
notify.setContentText("");
notify.setAutoCancel(true);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notify.setSound(alarmSound);
notify.setLights(Color.BLUE, 500, 1000);
nM.notify(reqCode, notify.build());
Adding logcat when the activity is not launched:

This is reported issue for kitkat 4.4 not opening activity when click on notification here is an issue url
http://code.google.com/p/android/issues/detail?id=63236
http://code.google.com/p/android/issues/detail?id=61850
suggested workaround is to cancel existing PendingIntent, or use PendingIntent.FLAG_CANCEL_CURRENT
OR
Try below
Adding a flag in Activity in AndroidManifiest.xml
android:exported="true"
回答2:
This issue is known for Android Kitkat 4.4 and Lollipop. Please add :
android:exported="true"
in android manifest inside activity tag which is supposed to be opened after tapping notification from status bar
回答3:
You can also add PendingIntent.FLAG_ONE_SHOT to fix this.
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT);
回答4:
Add android:exported = "true" in the manifest
<activity
android:name=".ListActivity"
android:label="ListActivity"
android:exported="true">
</activity>
ListActivity is the activity which will be opened on the notification click.

My above code is working well for all OS version except Kitkat 4.4 and 4.4 + But i have got solution i, put the receiver in another process and it works well for all most Android OS versions...
Like this way..
activity android:name=".NotifyReciever" android:process=":remote"
and we can learn more about processes here....
Should I use android: process =":remote" in my receiver?

The solution proposed by mass has worked for me and it's very simple, no need to change your code:
In your AndroidManifest.xml add the following attribute to your <activity> tag:
android:exported="true"
It has worked in a Samsung Galaxy Young 2 with Android 4.4.2.

Try to replace this
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); // To open only one activity on launch.
PendingIntent pIntent = PendingIntent.getActivity(context, reqCode,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
to
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); // To open only one activity on launch.
PendingIntent pIntent = PendingIntent.getActivity(context, reqCode, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK);
it will work for all version even with Kitkat also.
Note : Activity will be started outside of the context of an existing activity, so you must use the Intent.FLAG_ACTIVITY_NEW_TASK launch flag in the Intent.
回答8:
If android:exported="true" doesn't work for you, just redirect the intent from your LAUNCHER activity.
In your LAUNCHER activity check for incoming notifications as follows:
if(getIntent().hasExtra("type") && getIntent().getStringExtra("type").compareTo("notification")==0){
Intent redirect = new Intent(getIntent());
redirect.setClass(this,YourNotificationActivity.class);
startActivity(redirect);
}
If you need to filter the intent then use:
Intent incoming = getIntent();
if(intent.hasExtra("type") && intent.getStringExtra("type").compareTo("notification")==0){
Intent outgoing = new Intent(this, YourNotificationActivity.class);
outgoing.putExtra("title", incoming.getStringExtra("title");
outgoing.putExtra("content", incoming.getStringExtra("content");
startActivity(outgoing);
}

I hope it will help u.
long uniqueId= System.currentTimeMillis();
/** This is the part to let your application recognise difference notification when the user click on the notification.
* You could use any unique string to represent your notification. But be sure each notification have difference action name.
**/
taskDetailIntent.setAction("notifi" + uniqueId);
PendingIntent contentIntent = PendingIntent.
getActivity(this, 0, taskDetailIntent, PendingIntent.FLAG_ONE_SHOT);
builder.setContentIntent(contentIntent);
/** Set the unique id to let Notification Manager knows this is a another notification instead of same notification.
* If you use the same uniqueId for each notification, the Notification Manager will assume that is same notification
* and would replace the previous notification. **/
notificationManager.notify((int) uniqueId, builder.build());
