I had a similar problem and plusminus suggested i make this call

myMapView.invalidate();

to force the map to redraw. I haven't had time to try it out yet, but give it a try and let us know if it fixed your issue.

Hi!

I have a silly doubt, how to convert the strings coordinates: 37.423157,-122.085008 to int: 37423157, -122085008
like you did on the code above?



Thx in advance.

following this application I found that if start and end are way too far the current zoom level dont allow two pins and route to be shown in map

I found a way how to dynamically adjust the zoom level so that whatever two destinations you add you can still see the two pins on map
for e.g
NJ to MA is hardly 215 miles
NJ to IL is 785miles
MA to CA is 3000 miles

But the zoom level which is calculated dynamically according to latitude/longitude and points on map shows it

Dont know if my ignorence allowed me to waste whole night or some of us are facing this problem also

If you are in same boat do let me know I will paste the code here

I went through this tutorial, but I am unable to get the map to show up. The emulator just shows a grid with a circle in the middle, and then the button from the layout. Pardon my ignorance, but I am new to both JAVA and Android. It looks like I would need to DL a maptile from Google, but I am not sure how to go about doing that.

any help is appreciated!

Thanks!

Are you behind a proxy ?

Yes most likely..... if that is the case, if I were not behind a proxy, would it go and get the map tile automatically?

Hi just one question,

google has a driving direction.
Has anybody an idea if I can regognize (I travel on a road from point a to b) the next incoming roads or one road that crosses this road. Because I need this to get roadsections to save data to this road sections which i get from the gps and the CAN -bus of a car. Or has anybody another idea to devide the driven road in sections. But it must be always the same section length for all users?

Maybe someone has an idea?

Thanxx

Hello Christian,

imo this is really really hard (probably impossible if you want the results to be satisfying) to do this just with GoogleMaps, as one does not have access to the underlying mapdata.

But there is a route service (imo they had xml-reponse to requests) to get nearby streets, what could be a tiny point to start with. But unfortunately I forgot the name of that service

Hi All,
is it possible to start the Overlay class with an Intent ? That you only send the coord. (x,y) with the Intent and then you draw the PINs and so on ?
Is that possible ?
Thanks.

Yes it is.
Look in the apidocs for registerReceiver, so you can handle intents directly within your activity.

Hi plusminus

Thanks for this app, it's a really great intro to Android

One quick question.

How would I go about changing this app to move the "show me the directions" button to another activity? so that when the app starts all that I see is the button, upon pressing it I'm taken to another activity with the map in it only. So this is really separating one activity into two. I can't imagine it being too difficult but I cannot get it to work no matter what.

Could you please advise?

Thank you

Michal
