remove SMS notification

 Hi,
I have a BroadcastReceiver that fetches incoming SMSs. I need to know how
can I remove/cancel the notification for a particular SMS. I found no way to
list the contents of the notifications bar, and also only marking a SMS as
read doesn't do the trick.
Is it possible to remove a particular notification from the notification
bar?

Thanks

remove SMS notification

 I would also like to know how to do this, but for missed call
notifications. I'm worried that it is not (yet) allowed by the SDK.

Anyone?

1. Custom Toast from a Service

I am able to display a custom Toast from an Activity; however, a
service does not inherit the findViewById() method needed to build the
custom Toast.  Is there a way around this?  See below:

public class CService extends Service {
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public void onStart(Intent i,int startid) {
        LayoutInflater inflater = getLayoutInflater();
        View layout = inflater.inflate(R.layout.toast_layout,
                               (ViewGroup)
findViewById(R.id.toast_layout_root));  // I get error: method
findViewById is undefined for CService

        ImageView image = (ImageView) layout.findViewById(R.id.image);
        image.setImageResource(R.drawable.android);
        TextView text = (TextView) layout.findViewById(R.id.text);
        text.setText("Hello! This is a custom toast!");

        Toast toast = new Toast(getApplicationContext());
        toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
        toast.setDuration(Toast.LENGTH_LONG);
        toast.setView(layout);
        toast.show();
    }

2. Bluetooth Serial Connection from Milestone (Droid) Android 2.1 to Holux M241 GPSLogger stalls

Hi everyone,

I need some help, I am not sure whether I am using the Bluetooth API
in a wrong way or whether I discovered a bug. First of all, sorry for
all the verbose output, I already tried hard to shorten it and I hope
it is sufficient to understand the problem. Should you need more
output - I got plenty!

Thank you for your time!
Marek

Here is the short summary:

Serial Bluetooth connection blocks in readline of BufferedReader
although the GPSLogger sent more data, Connection library worked fine
on desktop linux machiene connected to GPSLogger via bluetooth.

Here is the long version:

I am attempting to write an application that connects my Motorola
Milestone (Droid) with Android 2.1 to my Holux M241 GPSLogger and to
download the contents of the memory. I want to be able to dump my
GPSLoggers memory to my mobile phone so that I can delete the
GPSLoggers memory contents and it can continue to log positions. I
read the source code to MTKBabel on linux for the protocol involved
and wrote some classes to communicate with the GPSLogger on my Android
phone. Before porting my communication library to Android I did try it
out with my desktop computer and everything worked fine (downloading
the whole memory consistently without problems). Then I ported the
communication library to Android and wrote several simple Activities
that enable the user to select the Bluetooth device and to connect and
download.


Problem description:

Unfortunately the download stalls unreproducibly after a random amount
of downloaded data. Sometimes (but very rarely) the download finishes
without problems but mostly my code stalls in the readline of the
BufferedReader that controls the InputStream of the serial bluetooth
connection.

I have attached the logcat output of my application and the hcidump
but do not understand the hcidump output (The F's are the GPSLogger's
memory contents which I deleted so you cannot see where I have
been ;-) - Download works from the desktop with other applications
(e.g. mtkbabel) ).

Here is my analysis so far:

In fact the last message received from the GPSLogger is the one at
2010-05-14 22:10:05.632079 in the hcidump output. Although more is
received in the hcidump output, it is not passed to the java
BufferedReader.
