How to calculate co-ordinates on touch in android on screen?

I implemented program to calculate co-ordinates, pressure, orientation, finger size etc on blackcanvas(canvas). But I need to calculate these on top of every application. That is on top of PDF, web browser etc. i.e. It should run as a background process. It has to capture every touch instances of screen. I should bind screen to canvas.

So using WindowManager.LayoutParams
when I am calling wm1.addView(bcan, params);
It is throwing an error
You should have your activity implements OnTouchListener, not SensorEventListener.
public class CaptureEventsActivity extends Activity implements OnTouchListener {
...
// Set the listener as itself
setOnTouchListener(CaptureEventsActivity.this);
...
#Override
public boolean onTouch(View v, MotionEvent event) {
// Do things here
}
}
By the way, you might not want to do everything in onCreate(), creating methods like setView() do things related with the view would be better. It does no harm, just a good habbit.
Hope this helps (:

J2ME, Nokia, HttpConnection

This code works fine on SonyEricsson and Motorola cellphones, but on Nokia it either fails at the beginnig not making any request at all or returns empty response, depending on model.
HttpConnection hc = null;

InputStreamReader isr = null;
String result = "";
try

int rc = hc.getResponseCode();
if (rc != HttpConnection.HTTP_OK)

isr = new InputStreamReader(is, "utf-8");
int ch;

I am not sure if this will work for you but I had a similar problem and found that specifying a port number made it work (on some older Nokia models). i.e convert:
http://www.mysite.com/my_page.html
to:
http://mysite.com:80/my_page.html

Filter a SharePoint list by audience

I am very new to Sharepoint development. I have the following code that I need to have display the list items by targeted audience. I know I am suppose to add something like this
AudienceLoader audienceLoader = AudienceLoader.GetAudienceLoader();
foreach (SPListItem listItem in list.Items)
{
// get roles the list item is targeted to
string audienceFieldValue = (string)listItem[k_AudienceColumn];
// quickly check if the user belongs to any of those roles
if (AudienceManager.IsCurrentUserInAudienceOf(audienceLoader,
audienceFieldValue,
false))
But I have no idea where to place it in my code below. Please I would appreciate any of your advise.

Telerik RadGrid Export to Excel. Missing operand before '=' operator

I am getting the error
Missing operand before '=' operator.
when I try and export and the code is running fine in the grid.
Here is the code for the web part. The error only occurs on the rebind. It works fine in the grid itself. Is there any way to narrow down the exact thing it is erroring on?
I am willing to pay for a support / solution to this problem, I just need it to work.
