    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 13,
            14, new GeoUpdateHandler());


}

@Override
protected boolean isRouteDisplayed() {
    return false;
}

public class GeoUpdateHandler implements LocationListener {

    @Override
    public void onLocationChanged(Location location) {
        int lat = (int) (location.getLatitude() * 1E6);
        int lng = (int) (location.getLongitude() * 1E6);
        GeoPoint point = new GeoPoint(lat, lng);
        mapController.animateTo(point); //  mapController.setCenter(point);




    }

    @Override
    public void onProviderDisabled(String provider) {
    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }
}

}

This is My mainfest ?xml version="1.0" encoding="utf-8"?>

<application android:icon="@drawable/icon" android:label="@string/app_name">

<uses-library android:name="com.google.android.maps" />
    <activity android:name=".ShowMap"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<uses-library android:required="true" android:name="com.google.android.maps"&开发者_如何学Cgt;</uses-library>

And main.xml

           <?xml version="1.0" encoding="utf-8"?>
         <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/mainlayout"
         android:orientation="vertical"
          android:layout_width="fill_parent"
         android:layout_height="fill_parent" >

        <com.google.android.maps.MapView
            android:id="@+id/mapview"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:enabled="true"
                android:clickable="true"

             android:apiKey="0cHF-o_cvW1DEz3ocWAyybGqUsg8aUlwKMoyr4A"
             />

Do you have the required permissions in place in the AndroidManifest.xml? In an Android app that I've made for GPS + Maps I have the following:

<uses-permission android:name="android.permission.ACCESS_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_GPS" /> 

This is a problem with an API-Key.

Here you can do it.

You need to generate different one for each emulator, device etc. and for final release, and you need to merge them with an keystore you're using, what sux, but there is no different way :/.

Good luck!
