Hi Mike, thanks for your answer.
No, I don't implement the Serializible Interface. The class gets the lon/lat pairs and if i call saveFile()-method, I save my way- and trackpoints on the sdcard (my source code blow up so i decide to implement this in an own class). Now my question is: if I have stored many way- and trackpoints and if the config change i call getTrackpoints() for example - how efficient is that and how fast is that?? I use a StringBuilder with: <trkpt lat=\""+lat+"\" lon=\""+lon+"\">\n" +"</trkpt>". So if i get a new location each second and if my track is 20km long, i think, that this is a cost-afflicted function (i don't drive, i walk or i drive with a bike)? I never implement the Serializible interface. Is this the best way?? Whats up with the efficency in this case (battery, responsivness and so on) My Location variables only holds lat and lon value. This is not the problem. Thanks, Stefan --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
