    }
    catch (Exception e) {
        e.printStackTrace();
    }
    return newsItems;
}
}

我必须做类似的事情，但是对于不同的web服务。但是，org.apache.http导入在较新版本中不起作用。我可以回到旧版本，但这似乎并不是最佳的。目前做这样的事情是什么（连接到web服务和读取数据）？任何人都可以给我一个简单的例子，或解释我应该做什么？谢谢

现在Android支持HttpURLConnection而不是Apache Http，

你可以在这里找到一些参考资料：

https://developer.android.com/training/basics/network-ops/connecting.html

https://developer.android.com/reference/java/net/HttpURLConnection.html

此外，您应该检查改造：

Android连接到webservice，org.apache.http是否已被删除？
