我需要在物理 Android 设备上运行地图，我该怎么做？

我不想使用 AVD 来调试它。

顺便说一句，我在 AVD 上遇到了同样的错误，所以请帮忙？这是我的代码 

<com.google.android.maps.MapView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/map"
        android:apiKey="0enZtoViiB7JtEUxmyjwYWuw0Hz8pdTqNNWtBjQ"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true" />

AndroidManifest.xml

<uses-library android:name="com.google.android.maps" />

活动：

public class AroundMeActivity extends MapActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.qa_layout_activity);

    MapView mapView = (MapView) findViewById(R.id.map);
    mapView.setBuiltInZoomControls(true);
}

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

这Exception通常意味着您的项目中存在符号冲突。确保您maps.jar在项目中只包含一次。

public class second extends MapActivity

MapView mapView;

Location location;
@Override

            mapView = (MapView) findViewById(R.id.MapView);
            mapView.setBuiltInZoomControls(true);
            mapView.setSatellite(true);

            mapController = mapView.getController();
            mapController.setZoom(16);

            GeoPoint point = new GeoPoint(lat,lon);
//lat and lon are integer values for describing the location
            mapView.invalidate();
            mapController.animateTo(point);
