WiFi Direct在Samsung Devices上无法正常工作

Question

我正在开发基于WiFi的文件共享项目。我面临的问题是三星设备没有收到文件。这是我的代码。

private static final String TAG = MainReceiver.class.getName();
public static final String ACTION_TRANSFER_DONE = "action_transfer_done";
private MainActivity mActivity;
public MainReceiver(){
    super();
}

public MainReceiver(MainActivity activity){
    super();
    mActivity = activity;
}

@Override
public void onReceive(Context context, Intent intent)
{
    if (intent.getAction().toString().equalsIgnoreCase("action_transfer_done"))
    {
        Log.d(TAG, "transfer done");
        List<String> mFileNames = intent.getStringArrayListExtra(ServerService.FILES_NAME);
        mActivity.transferDone(mFileNames);
    }
}
