7. Manually enter the longitude and latitude of your location. (Note they are in
   reverse order.)


8. Click Send.

Back in the emulator, notice that the Google Map now shows the

location you seeded. Your screen should now display your location

as Yosemite Valley, as shown in Figure.

Your emulator now has a simulated location.

Finding the Last Known Location

To add location support to MyFirstAndroidApp, edit the file My First

AndroidApp .java. First, you must add the appropriate import

statements:

import android.location.Location;
import android.location.LocationManager;

Now, create a new method called getLocation() in your class and

make a call to this method in your onCreate() method. The

getLocation() method gets the last known location on the phone

and logs it as an informational message. If the operation fails for

some reason, the method logs an error.

The getLocation() method should look something like this:

public void getLocation() {
try {
LocationManager locMgr = (LocationManager)
getSystemService(LOCATION_SERVICE);
Location recentLoc = locMgr.
getLastKnownLocation(LocationManager.GPS_PROVIDER);
Log.i(DEBUG_TAG, “loc: “ + recentLoc.toString());
}
catch (Exception e) {
Log.e(DEBUG_TAG, “Location failed”, e);
}
}
