Just for your information, the speed conversion does already exist in the GPSExample program. When you touch the header of the speed column the speed unit does change from m/s to km/h to miles/h and so on.
It's done in the UpdateDispSpeed routine in the GPSPaths module.

I'm trying to compile the GPS demo and I'm getting the following error:

Compiling code. Error
Error parsing program.
Error description: Unknown type: webviewextras
Are you missing a library reference?
Occurred on line: 138
Dim MapViewerExtra As WebViewExtras

I've seen the other posts about the additional libraries I need and have created an AddLibraries folder and have ByteConverter, Dialogs, WebViewExtras in there.

Anyone offer any further suggestions?

Edited to add: I just checked and I can compile and run the WebViewExtras demo program.

Problem fixed. My apologies.

I hadn't used the check boxes to add the libraries.

Amazing the difference reading the manual makes

OK, thanks you!

It's a very good example.
I'll have to look in depth. I'm a beginner and I'm still learning how everything works.
Thanks.

Morning all
When Running the GPS Example on my Galaxy Tab 10.1 or on my HD2 phone I get the following exception:

Error Occurred
An Error has occurred in sub: main_gps1_locationchanged (java line: 1415)
lava.lang.
NumberFormatException
Continue ?

--
The App sterts Ok and picks up several sattelites in the SATS Tab, but will go no further.

btw: I notice that the Altitude reading is '1,653.1' and it seems that the format of this should not have the ',' (comma) in it. Perhaps this is what is troubling the java NumberFormatException.

Is there perhaps a setting in my phone I can change (ie to make the format of the Altitude returned from my GPS 'correct') or is it an omission in the java library that stops it from properly handling an Altitude (or any other number) that is returned with a ',' in the string ?

I'd appreciate some advice on getting this App to work in the same way everyone else seems to have done.

The bug was in the format as you suspected.
The code in the first post has been updated.

Best regards.

Thanks Klaus
It works nicely on both devices now.

I'm really looking forward to learning from your code

I hope I can contribute something every now and again as a gesture of respect and thanks for your very generous code and postings.

Thanks again

Malcolm

Gruetzi Klaus,

Sorry for splitting hairs once again (I think in French you'd say, "splitting hairs into 4 pieces"). Anyway, there are a couple of undefined variables...

Activity Main
MapYCursor: Line 32 (declares MapXCursor twice)

Activity GPSPaths
GPSFilenameOld: line 106
txt: lines 228/252
MapZoomCalculated: line 260
GPSPathModified: lines 280/785

Activity Satellites

Hallo Robert,
Thank's for having "coupé les cheveux en 4", but I don't consider it like that.
I had'n looked at the code with the IDE version1.8, the new feature showing non declared variables is very useful.
In the first post I updated the program version 1.56

Best regards and thank you.
