Apps Need help copying code into new app

[warrenwsav]

Hello,

I found a small example of code for a GPS location app to use in Eclipse. Below is the URL of where the code is. I created a class and then pasted the code in there. I immediately got errors which you can see marked. I opened the error box for one which you can see in the screen shot attached. Well, it won't let me post links or images as a new user. The word Activity and LocationManager in the function line is highlited as an error as many others in the code.

Can someone tell me why I get these errors? How do I run the code from the web page? Thanks!!

/* CAL METHOD requestLocationUpdates */

// Parameters :
// First(provider) : the name of the provider with which to register
// Second(minTime) : the minimum time interval for notifications,
// in milliseconds. This field is only used as a hint

Explanation :


requestLocationUpdates Method :

Registers the current activity to be notified periodically by the named provider. Periodically, the supplied LocationListener will be called with the current Location or with status updates.

Parameters :

First(provider) : the name of the provider with which to register
Second(minTime) : the minimum time interval for notifications, in milliseconds. This field is only used as a hint to conserve power, and actual time between location updates may be greater or lesser than this value.
Third(minDistance) : the minimum distance interval for notifications, in meters
Fourth(listener) : a {#link LocationListener} whose onLocationChanged(Location) method will be called for each location update


onLocationChanged Method :

Called after each 3 sec ( we have defined in requestLocationUpdates ).

onProviderDisabled Method :

Called when User off Gps in phone setting.

onProviderEnabled Method :

Called when User on Gps in phone setting
