That's not possible. Double-check your logs and what variable they point to.

TreKing I had this in a previous thread to but that problem was fixed. This

Your location variable is null.

It is a NullPointerException so I suppose it is returning null.

NullPointerExceptions are cause by *objects* that are set to null. The only
*object* in that statement is
But the thing is location can't be null. If it was the app wouldn't have

if (location != null) {

Okay. Maybe I am missing something here but AFAIK the if statement check to
see that location is not equal to null and if that is true (location not
being null)
it passes it on to the Overlay.
Did I get that right?

Correct. But this is not where the crash is.

Right. Got it now.
Basically I need to check location for null twice. Once in the Activity and
once in the Overlay.
Thanks

I needed a custom graphic and text on the location point and the book I used
said it was not possible with MyLocationOverlay. Also later on I plan on
adding a few more things that would not work with MyLocationOverlay.

Well your overlay has access to the MapView on which it is drawing, which in
turn has a Context, which is all you really need for
I should probably change it.
Seeing as this book has given me more errors than knowledge I think I'd get
another one. Maybe one of Mark's.
@Mark: Where can I get your book in New Delhi, India? I can't find it at any

You can use a status bar notification, or implement some sort of
callback (listener) that takes you back to the activity, where you can
e.g. display a dialog:
myObject.setErrorListener(new ErrorListener() {
@Override
public void somethingBadHappened( ) {
// display a
I think I'll go with Status Bar notification. I might add a form later
asking them whether or not they have a SIM card and ship it as a custom
variable with ACRA. (Only reason I can think of for the null value is a
missing SIM card as I use the cell network for location.)
And before someone tells

You're 14?

Thanks Mark. I really appreciate all the help all of you have given me so
far. I got your books and they are a lot more straightforward than the one I
was using so far.

Thanks a lot for your help.
