当我运行我的应用程序（谷歌地图应用程序）时，我看不到地图。我只看到一个白屏（如下图所示）。
主要节日

活动
package com.williamroma.example;
import com.google.android.maps.MapActivity;
import android.app.Activity;
import android.os.Bundle;
public class GoogleMapActivity extends MapActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
这是我看到的屏幕，我想在这个 tuotiral http://www.androidhive.info/2012/01/android-working-with-google-maps/中看到地图
