下载管理器崩溃上下载完成

这是我的广播接收器：下载管理器崩溃上下载完成

BroadcastReceiver broadcast = new BroadcastReceiver() { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     String action = intent.getAction(); 
     if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) { 
      dwnId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0); 
      Cursor c = DownloadManagerWrapper.getInstance(getActivity()).getDownloadManager().query(new DownloadManager.Query().setFilterById(dwnId)); 
      c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS)); 
     } else { 
      Toast.makeText(getActivity(), "ERROR!", Toast.LENGTH_SHORT).show(); 
     } 

    } 
};

在我onCreateView我注册它：

(getActivity()).registerReceiver(broadcast, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

这是我DownloadManagerWrapper看起来像：

public class DownloadManagerWrapper { 
private static final String DOWNLOAD_SERVICE = "download"; 

private DownloadManager mgr; 

private static DownloadManagerWrapper i; 

private DownloadManagerWrapper(Context c) { 
    mgr = (DownloadManager) c.getSystemService(DOWNLOAD_SERVICE); 
} 

public static DownloadManagerWrapper getInstance(Context c) { 
    if (i == null) { 
     i = new DownloadManagerWrapper(c); 
    } 
    return i; 
} 

public DownloadManager getDownloadManager() { 
    return mgr; 
} 

}

这就是我所做的，使它成为FC：

if(Util.hasNetworkConnection(ctx)){ 
     Uri destination = Uri.parse("file://" + Environment.getExternalStorageDirectory().getAbsolutePath() + "/media/video.mp4"); 
     DownloadManagerWrapper.getInstance(ctx).getDownloadManager().enqueue(new DownloadManager.Request(uri).setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE).setAllowedOverRoaming(false).setDestinationUri(destination)); 
    }else{ 
     Toast.makeText(ctx, "No Internet Available!!", Toast.LENGTH_SHORT).show(); 
    }

我得到这个错误：

您是否尝试过调试Environment.getExternalStorageDirectory（）。getAbsolutePath（）+“/media/video.mp4”以查看它是否返回正确的路由？ – 2013-02-14 13:11:09

是的，我不得不做广告“file：//”。现在它是正确的。但我有另一个问题。我现在要编辑我的问题 – 2013-02-14 13:13:07

评论这条线，使得它的工作：

c.getInt（c.getColumnIndex（DownloadManager.COLUMN_STATUS））;

它为什么有效？ – joseRo 2014-02-11 11:30:53
