How do you get your current position in Android?

Hey,

I was wondering if there was a straight forward way to get the current location from an android device. I tried looking on the Android Developer site, but their examples only confused me... and also seemed like a very roundabout way to do something so simple, which made me think I missed something in the translation..?

Could anyone point me to a more simpler straight forward tutorial?

Thanks in advance!

Are you looking for an app that will do this or how to code this in android?

There is an app called maverick that will give yours coordinates

Hm... tried the code at the link, and it runs without errors...

But I'm having trouble getting it to run on the emulator, the command telnet localhost 5554 isn't working... is there another way around this?

It just says connection refused. Tried this on ubintu and Mac OSX.

I ran this command in the terminal after starting the simulator.

The port number of the emulator should be displayed in the title of the emulator window. Like this: 5554 MyEmulator

What does it say in your emulator?

Hm, never noticed that before... but mine says 5554.

The connection works now for some odd reason after restarting... but I still see a blank screen on the emulator.

This is what I have... do I have it right?

Do you have Maps API Key from Google? You have to get one in order to use the maps. Here is how you get it:

Yes, I got the google maps API key using keytool.

The application works fine - it tells you the current location when you change it.

There is no map view in this example, it is only an appication which tells you the current location.

So, you start the app and then change the location through the telnet and the coordinates will be displayed on the blank screen. Thats it, no map view involved.
