Android gridview中的图像在emulator中显示，但在设备中不显示

我有一个图像gridView，我正在使用url中的图像

它在模拟器中正常工作，但图像不会显示在设备中。日志中没有错误。下面是我尝试过的代码

public class Home extends Fragment implements TabHost.OnTabChangeListener,
        OnClickListener {

    TabHost tabHost;
    View vi;
    StaggeredAdapter adapter;
    TextView tv;
    public String urls[] = {

        _row = row;
    }
