我只是尝试使用android中的googlemaps v2。当我运行它没有错误但地图不能显示我从lat和long设置的地方（显示空白区域）。谁能告诉我我的想法？非常感谢你。

这是logcat

这是我的主要活动

    map.moveCamera(CameraUpdateFactory.newLatLngZoom(RAGUNAN, 15));
    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);

    }

@Override

    getMenuInflater().inflate(R.menu.main, menu);
    return true;

}
