Android Question A question about "Types"

[Roger Daley]

Hi All,

I have been playing round with Klaus's "GPSExample" as a learning excercise. In trying something different I changed the Name part of this "Type" line:

    Type GPSLocation(Latitude As Double, Longitude As Double, Altitude As Double, Distance As Double, DistTot As Double, Time As Long, Speed As Float, Bearing As Float, Marker As Boolean)

to

    Type GeoLocation(Latitude As Double, Longitude As Double, Altitude As Double, Distance As Double, DistTot As Double, Time As Long, Speed As Float, Bearing As Float, Marker As Boolean)

I then changed all occurences of GPSLocation to GeoLocation in all modules.

When I run the code [Release] I get this error:

When I run the code [Debug Legacy] I get this:
If I change the code back all runs OK.

My understanding was that in defining a "Type" you assign a name, whether it is GPSLocation or GeoLocation should not matter.

Can someone please explain in simple terms what it is I am missing.

The name doesn't matter with one exception. When you serialize an object with RandomAccessFile the type name is saved to later you will be able to read the object. If the original name no longer exist then it will fail.

Thanks Erel,

I will keep the original name and try to remember this one for the future.
