Hello pluminus, the Notification functionality in SDK m3 had the option to set the message on the status bar, which automatically disappeared after a couple of seconds. Is this still available on SDK m5? An alternate solution (but not smart) would be to have a service running, clearing the message every so often.

Having a issue with the overriding of onClickView, I have a direct copy of your code however I receive the error

"The method onClick(View) of type new View.OnClickListener(){} must override a superclass method"

Any ideas?

are they the same or not can you guys give us some examples, btw im using a Chronometer and i wanted to run it in the background if i exit the app and it will show in the notification status bar and when clicked it a timer will then be seen .

one more thing is the back button of the emulator is the only way to exit an activity? how about if i have one activity like MapView?

thanks

MrSnowflake · by **MrSnowflake** » Sun Nov 23, 2008 2:16 pm

The first parameter is the context of the Application which creates the notification, and the last is the Intent to launch when the user touches the extended info of the notification (ie. If you receive a new message, the last param will be an intent to start the ViewMessage activity).
I got this info from the link you gave...

Also check the samples directory, there are some good Notification examples in there.

Artur79 · by **Artur79** » Sun Nov 23, 2008 7:01 pm

thanks for an answer.
I suppose, for plusminus application example, it should be something like this:

but there's a problem with a type or last param, should be PendingIntent, how to get this ?

Tinky · by **Tinky** » Mon Nov 24, 2008 3:07 pm

Hello,

I have created a sample example of statusbar notification, but now i am unable to start another intent when i click on statusbar notification icon,
my code is

Intent contentIntent = new Intent(this, HelloActivity.class);

contentIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Notification notification = new Notification(imageID, msg, System.currentTimeMillis());

PendingIntent appIntent = PendingIntent.getActivity(this, 0,contentIntent, 0);

notification.vibrate = new long[]{100, 250, 100, 500};

notification.setLatestEventInfo(this, getText(R.string.app_name), getText(R.string.app_name), appIntent);

nm.notify(id, notification);

I am able to start another intent on clicking the status bar notification icon as given below

==> click and hold on the status bar icon, then drag down to the bottom of the screen and let go

on doing this, a list of all notification get display on that dragged screen and we can click on to that to start the respective intent.

Regards
Tinky

Hi,

I see that the above example is written in an earlier SDK. I have written a notification example using the APIs of 1.5. Here is the code for the same:

Code: Select all: public class SimpleNotification extends Activity { private NotificationManager mNotificationManager; private int SIMPLE_NOTFICATION_ID; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); final Notification notifyDetails = new Notification(R.drawable.android,"New Alert, Click Me!",System.currentTimeMillis()); Button start = (Button)findViewById(R.id.notifyButton); Button cancel = (Button)findViewById(R.id.cancelButton); start.setOnClickListener(new OnClickListener() { public void onClick(View v) { Context context = getApplicationContext(); CharSequence contentTitle = "Notification Details..."; CharSequence contentText = "Browse Android Official Site by clicking me"; Intent notifyIntent = new Intent(android.content.Intent.ACTION_VIEW,Uri.parse("http://www.android.com")); PendingIntent intent = PendingIntent.getActivity(SimpleNotification.this, 0, notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK); notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent); mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails); } }); cancel.setOnClickListener(new OnClickListener() { public void onClick(View v) { mNotificationManager.cancel(SIMPLE_NOTFICATION_ID); } }); } }

Hope this helps people who are looking at the latest SDK.
