I need to know when a notification is created because I want to change the audio mode. Is possible?
Thank you very much.
With the release of Android 4.3 it is possible to get Notifications within a third-party app.
See NotificationListenerService for reference
You can use Notification class, However an answer on SO, suggests that
There is currently no generic way to intercept Notifications sent from other applications.
However if you want to listen something like SMS notifications than this link can be useful for you..

I'd like my android auto notification to not have any reply mechanism to it. I just want a notification that you can swipe to dismiss, but the only two options i see for android auto are messaging and audio. The messaging makes the notification have a reply to it like this:
notice how there is a microphone for user to reply. I dont want that on my notification. I only want to display info but no reply mechanism. I am not interested in reply, only to notify user of something. i want it to look like this instead but it seems only system has this kinds of notifications.
Android Auto has defined guidelines for Messaging Apps.
It didn't consider normal notifications as a scenario that needs to be addressed now in Auto environment.
We can hope it may be made more flexible on future along with measures to make sure that distraction is avoided by strict certification process.
So the answer to your question is - Not possible now.
I have never developed something in Android before, but now my company has put me on a project which includes android.
My question is this: Is it possible to write an application that runs in the background and waits for triggers (if that is the correct word for it). For instance lets say I want my application to do something as soon as you open your emails or as soon as you get an email. Is there some API that I can use to interact with other applications such as Mail. The application does not have to have any GUI, it will literally just push some information notifications on the mail just received or opened.
I don't require a to technical answer, but rather just yes or no, and indeed yes, where can I get more info on it. Also if it is not possible, is there some workaround to achieve this. I have googled it, but most of the links are how to send an email from your application.
Thanks
EDIT: So it can even be triggered when a notification is received. Then I just want to look at the notification and determine if it is an email?
You could register BroadCastReceiver for the actions that you need to be caught
I'd like to be able to listen for notifications being sent to the status bar, and intercept and suppress (temporarily) those notifications.
I've seen AccessabilityEvent.TYPE_NOTIFICATION_STATE_CHANGED, and NotificationListenerService.
However, I just don't want to be informed when a notification is displayed, I want to prevent the notification from being displayed.
I can see how this could potentially be a security threat, so I can understand if it's not possible. Is this possible? If so, how would I go about doing it?
I think you're on the right track with the NotificationListenerService. Google has made these API's available from Android 4.3 on, so an application using this method would just be available for new devices.
In the following blogpost you can find an example of what you can do with the NotificationListenerService: http://weimenglee.blogspot.ch/2014/03/android-tip-notification-listener.html
The basic idea is to implement the onNotificationPosted() method, which gives you a StatusBarNotification instance. You should then be able to cancel the notification with this.cancelNotification(
notif.getPackageName(),
notif.getTag(),
notif.getId());
See the blogpost for a further description of what to extend and how to implement the methods.
Hope this helps.
I'm currently working on app that read certain notifications and then silencing some of them. I've managed doing this using NotificationListenerService on Android 4.3+ but I would like to make it compatible for previous versions too. So is there anyway to listening to incoming notifications and getting its content?
I heard about AccesibilityService but I don't quite understand if it is possible to use it to read notifications' content and how. Any suggestions?
Thanks from adavnce!
It's possible with the accessibility service (event 64)
You can get at the notification object from this and then parse it.
There's a sample class of parsing the notification here: http://notifications-widget.googlecode.com/svn/trunk/NotificationsWidget/src/com/roymam/android/notificationswidget/NotificationParser.java
The android home page displays notifications from different applications.
I would like to read those notifications using my program.
I tried to find information on that in forums and in android help but I was not able to find any information.
My actual goal is to read the notifications and if the notification is about an email from a certain person then I want to perform something in my application.(I use touch down for my email)
Any help is appreciated.
Not possible due to security reasons.
If you want to respond to events then you should try listening to them directly with intents.
You need to create an AccessibilityService and set it to listen to TYPE_NOTIFICATION_STATE_CHANGED events. This way, each time any of the application packages specified while configuring the AccessibilityService generates a new notification, the onAccessibilityEvent callback of your service will be called with all the information about the notification.
