我嘗試使用Google maps API開發Android地圖應用程序。java.lang.SecurityException：提供者gps需要ACCESS_FINE_LOCATION權限
使用Google API測試幾個emulatet Android設備（2.1; 2.3.3; 4.0.3）。
的問題是，logcat中拋出這個我：

下面是代碼：
package map.test.activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
public class MapTestActivity extends MapActivity {
private MapController mapController;
private MapView mapView;
private LocationManager locationManager;
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.main); // bind the layout to the activity
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapController = mapView.getController();
mapController.setZoom(10); // Zoom 1 is world view
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, new GeoUpdateHandler());
} //public void
@Override
protected boolean isRouteDisplayed() {
return false;
}// protected boolean
public class GeoUpdateHandler implements LocationListener {
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);
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status,
Bundle extras) {

}

我已經嘗試轉變的位置的權限並將編譯器設置爲JAVA 1.6（並將@Override添加到最後三個公共空隙中）。 這可能是非常明顯的東西，但我剛開始用Java開發。
不幸的是我不斷收到同樣的錯誤。 – Teonee 2012-02-05 06:56:40
@Override只是一個註釋，建議使用它來指定重寫，但對相關代碼的操作沒有直接影響... – 2012-02-05 07:07:59
謝謝@Rahulgarg ..... – Lucifer 2012-02-05 11:36:51
