Ah sorry. No maps won't be on every devices. Any manufacturer can make a device and decide not to talk to Google to include maps.
You can't call out to the classes of the maps app as you don't have access to them. Intents are the way to do this on Android. Now, I don't know if we publish the intents needed to talk to the map app. Do a search. If you launch an intent and no app are available to answer the intent you'll get an exception I think. Just catch it. On Mon, Sep 13, 2010 at 10:06 PM, cool.manish <[email protected]> wrote: > Hi Xavier, > > Thanks for your reply.
