I have a server socket bound to a port and I want to send notifications using NotificationManager when a client connects. This all works well.
What I want to avoid is sending notifications if a specific activity is currently being used by the user. E.g., I'm trying to avoid something like GMail notification if I'm already reading email.

I have total 3 activities.
First activity(A) starts second activity(B). From Activity B, 3rd activity(C) is called.
Activity B, shows list with checkbox to select items and single OK button. On clicking OK button Activity C is called with selection.
When user clicks BACK button in Activity C, by default Activity B is displayed (with selected checkbox).
I want to display Activity A when BACK button is clicked in Activity C.
How to achieve that?
I have handled OnKeyDown() in Activity C to startactivity(A). it is working. But when user clicks BACK button on Activity A, again Activity C is displayed. while application should end.
In this direction how to skip Activity B is ever called?
Since I seem to have caught two activity references in a heapdump, where the Activity is set to singleTask. Romain's advice on avoiding memory leaks includes: "Avoid non-static inner classes in an activity if you don't control their life cycle, use a static inner class and make a weak reference to the activity inside"
What does this mean exactly? I can't find any examples, positive, or negative for this rule. I do have some non static inner classes in my activity. Most of them are anonymous inner classes like this one. I see hundreds of them in the samples:....................
In my application I notify the user with notifications, if something special happens:
public void triggerNotification(String msg) {
notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent contentIntent = new Intent(this, ABC.class);
Notification notification = new Notification(R.drawable.icon, msg, System.currentTimeMillis());
notification.setLatestEventInfo(this, "ABC", msg, PendingIntent.getActivity(this.getBaseContext(), 0, contentIntent, PendingIntent.FLAG_CANCEL_CURRENT));
notification.flags = Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(notificationCounter, notification);
notificationCounter++;
}
If the user clicks on the Notification, the onCreate() method is called. But I want that a specific method in my app is called, or if the app is not in the foreground, that it is brought back to the foreground. I know there are lots of tutorials that explain how to handle notifications, but I just don't understand them completely and wasn't ever able to implement the things like I'd like to.
From notification manager, how do I resume a task instead of creating a new instance of it?
I want to create a link in the status bar on the phone through notification manager. When I click on it, I want want a particular task to come to the foreground.
However, it seems my code always launch a new task even if there is an existing one running. For example, I click on the link the first time, a task shows up. When I click the second time, I see an animated task showing up again ... repeat that 5 times. And then when I hit "back" button, the 5 instances will disappear one by one (proving it's not just a single instance). code...

Do you know any way to by pass that ? I tried to create an Activity for each notification bu it seems ugly, and I can't find a way to launch an Activity without any view.

I have an Android Service which copies files to an ftp server.
While it is doing that, I want to send feedback to my Activity so the user knows what happens.
I tried implementing it using the RemoteMessengerServiceSample code, but I have a problem ... All messages I send during the ftp transfer arrive at my Activity the moment the copy operation is finished ... not message by message while the copy job runs as I would like.
Is there any way to fix this? Maybe i'm using the wrong method for sending messages to my activity?
I was wondering if there was a way for a website to send an alert/notification to a cell phone (smart phone, android, iphone... stuff like that) where the notification will ask the user a question and they have to answer the question and the response is sent back to the website and their answer is logged in the database.
I would also like to know if this notification could have checkboxes? I am needing this for a project and would like to know if there is anything out there like this.
I am little confused with the use of intents used for sending data to activity from service. In my application I have to have startactivity from the service and have to pass data ,so that activity can utilize the data while launching.For this i have written the following code Intent intent = new Intent(Service.this,Activity.class); intent.putExtra("data", data); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.start Activity(); I assume that the data is passed to the activity and can be parsed on the oncreate function of the activity.Now the service running in the background has to pass data to the activity continously for UI updates.For this I have written the following codeIntent intent = new Intent(Service.this, Activity.class); intent.putExtra("Data", data); intent.setAction(Intent.ACTION_ATTACH_DATA); sendBroadcast(intent,null); (Do I need to broadcast the intent???) In activity I have done following things:- Implemented broadcast reciever:private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (Intent.ACTION_ATTACH_DATA.equals(intent.getAction())) { Bundle extra = intent.getExtras(); float Data[] = extra.getFloatArray("Data"); update(Data);

View 2 Replies View RelatedI have a newbie question which is puzzling me regarding using Intents to start a new Activity but passing some data with the Intent for the new Activity to use. My app has (say) MainActivity from which I want to launch a second activity, SecondActivity, within the same app, whilst I pass an integer parameter to SecondActivity. Now my problem is : how do I receive the Intent when SecondActivity gets started and recover the value of the integer parameter ? Which member function of.
View 3 Replies View RelatedI am a bit new to Android. What I need to do is send data back and forth between an activity and a service locally. The information sent is sensitive and must not be able to be picked up by other apps. This excludes using broadcast and the onBind() function if I understand things correctly? So the activity needs to send some string parameters to the service. Also it somehow needs to tell the service which activity started it so the service can reply to the correct class since many different activities will use this service.
Once the service has fetched the information via a http request it is suppose to send that data (just a long string which will later be parsed) back to the activity that started it. How do I go about doing this? Using static variables/functions is not an option since again many actives will be using this service. Sure it would be possible to use a static array to hold the classes but that just seems ugly. It's only possible to send simple variables (not objects) via the intent? There must be a better way to do this.
Within the past week, I have gotten a "Sending..." notification at the bottom of my screen when I turn my phone on. Also, my phone gets a bit warm and the battery doesn't last a half a day. I use Handcent and have cleared the cache and the "unsent messages". I don't know what other program is sending things.
Nexus S AT&T
Android 4.0.4
I'm just wandering if there is a way to stop the notification tone from playing after I send a message?
Running android 2.1.
