I want to know how does notification read and unread functionality works in android. I want to know how the badges number count is set visible and invisible on read and unread message method.
When I create notification in my application then it will create successfully and add with +1 increment on badges. But after read this notification all other unread notification will also disappear. I want only the reeded message notification/count will be disappeared not for all.all other those are not open will be remain unread on badge. how could I did this.
same like as our message box functionality.

No there is no any direct method to do this. but i show you one way how to achieve this. This solution only working in SAMSUNG Devices. There is no guaranty it's working on all devices.

also another way is you can achieve this by App Widget Provider in Android. for more information go to AndroidWidgets
If you want to put it on Launcher Icon , then in android its not by default functionality given. The reason behind it is, when apk is generated, apk will not find that icon attached with it, so that is the main reason.
Alternate is, you can create widget for it. Creating widget is only solution to achieve this.

The problem here often appeared, but I didn't found anything about it for delphi and firemonkey.
I would like to display some information when my application detects an incoming call (Android).
I know it would be best to create my own phone application and set it as the default one.
But Android has Toas and Notification and I thought to use it.
1) I tried to use a toast but did not manage to display information ON THE incoming call screen
2) Notification displays the message but I must first swipe down notification bar. It gives me nothing. I would like information to appear for example like
information about the end of the battery (information available above all screen application)
Is anyone able to tell me something?
It may sound a weird question at first but I want to learn the name of the first alert in Android so that I can research how it is done.
What I mean is, for example, while you are talking to some person on WhatsApp, some other person or group sends you a message and you are firstly alerted on top of the screen for a few seconds (which is directly clickable) and then that notification takes its place back on the notification bar, meaning you have to scroll down this time to reach.
How can I search this? Or, if anyone has any tutorial about how to implement it, I'd appreciate much.
Thanks,
Its called Heads-up Notification.

I am given a task to show local push notification. I have successfully completed showing push notification on bar. But also I have to show local notification on app launching icon on home screen like in i-phone. See the image
I want this kind of notification. Here, may be the dialog I create using custom AlertDialog. But I'm stuck with the notification on the app icon i.e. that bubble containing notification no on upper right corner of app icon. I think this functionality is not given by android sdk. but our client says that she has seen these kinds of notifications on her Android mobile for some applications.
So is it possible in Android, and if yes then how to do it?
What you're looking for is a "badge" and I'm sorry to tell you that this does not exist on Android - your client must be mistaken.
One workaround you could do is to create a widget for your app (and you can even make it look like an app icon if you wish...), and you can add a badge or update how it looks any way you choose.
My app is using the new VoicemailContract functionality in ICS to insert voicemails that show up in the stock call log. I've got it working perfectly, but I can't figure out how to control the new Voicemail notification that pops up when the new voicemails are added. The notifications seem to be controlled by the Phone app, and even if I manually update the voicemail's IS_READ attribute, the notification doesn't go away. In fact, I can delete the voicemail altogether, and the notification doesn't go away. The only way that it goes away is if that notification is clicked, or if I manually go into the call log and open one of the new voicemails.
Does anyone have any idea on how to control that programmatically from my app?
Unfortunately you can't. Status bar notifications can only be cleared by the app that placed them there. The phone app is the app that placed it there and this is why only that app is able to clear it.
I wish there was a way to do this myself, but currently, there is not :(
I have seen in android native Email application that it updates the icon by showing how many new mails are there ?
Is it a service that updates the icon or is it a process who does it ?
Can someone tell me which file does this change ?
It cannot be done from the application. There are two ways that I know of to achieve that:
A widget that updates itself and changes its icon (but it's not a regular icon to an app)
Some launchers do that on regular icons (e.g. GoLauncher) but they do that from the launcher application code itself: they have a plugin that checks for pre-defined services (mail, Gmail, text messages, missed phone calls, etc.) and then draw a little notification on top of the application icon.
There is no line of code that can do that, at least not in Gingerbread...
What you can do (and that's what most applications that do that use) is create a 1x1 widget that updates its "number of events" whenever an event occurs.
