问题
I got a Activity which creates an alarm. The alarm calls a Broadcast Receiver. In on Receive i create a Notification with the extras from the Activity (ID, Title, Content). The Alarm triggers the Broadcast Receiver creates the notification well.
But when i re install the application or install a newer version and setup a new Alarm with a new title and content the receiver shows me the first create notification intent. i can create may Alarm triggers all works but they show always the first create Notification intents.
I use a internal application counter for creating a notification ID
public class CollectApplication extends Application {
private Integer reminderCount;
@Override
public void onCreate() {
reminderCount = 1;
super.onCreate();
}
public Integer getReminderCount() {
return reminderCount;
}
public void setReminderCount(Integer reminderCount) {
this.reminderCount = reminderCount;
}
}
Of course after re installing or updating the application the counter starts from 1. But i create a new intent with the same ID 1 so i override it right?
How to override it or remove the intent from the notification to create a new one with new extras to display?
Or Should i save the current ID in the shared preferences?

Use FLAG_UPDATE_CURRENT when you create your PendingIntent for the new Notification.

No, because you should only have one ID. You may wish to persist your reminder count, though.
回答2:
->Just add PendingIntent.FLAG_UPDATE_CURRENT
Example:
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
